Western Digital VelociRaptor 300 GB Bulk/OEM Hard Drive 2.5 Inch, 16 MB Cache, 10,000 RPM SATA II WD3000GLFS Review

Average Reviews:

(More customer reviews)There is no other speed improvement investment you can make on your computer that will have a more significant effect on speed than a fast hard drive. Faster video card? Nope. More memory? Nope. Faster CPU? Nope. I have done them all.
For home use, us hacks are forced to use mainstream parts because of costs. SCSI is the fastest alternative to SATA and EIDE drives. But, an Adaptec SCSI card costs about $300+ and the hard drive can cost $300 to $500 depending on size. SCSI hard drives for that reason are always smaller in capacity and most are under 100GB. I'm in engineering and my work computers have always been SCSI. But, you can make any dog computer rock by upgrading to SCSI if you have a big wallet.
This WD Velociraptor hard drive is the in between choice. It is not as fast as SCSI but close, and it is much faster than the standard hard drives. Compared to the 120GB SATA hard drive I replaced, I can notice a huge improvement for programs to load. If I had to guess I would say the speed is about double or a little more. Based on the specs for a 12msec standard hard drive, these are in the 5 to 6 msec range. Not bad for a $200 300GB hard drive. Some have complained about the cost per GB being high, but if you look at the cost per GB per second of the Velociraptor, it is the cheapest available on the planet. And remember, speed upgrades are not linear relative to costs. To get this close to SCSI speeds for this size hard drive I could spend $1000 in the SCSI world. I am impressed with this hard drive.
For those out there who might be hesitant because of the difficulty factor on how to transfer your current data onto the new hard drive, WD has created software which will do this whole change process for you with about 3 clicks of the mouse. The software called Data Lifeguard Tools comes on a CD with every retail version. This version sold here is the OEM version and has no software. But, you can download the tools for free from the WD website. All I had to do was add the new hard drive to my system and the software recognized it even though it was not partitioned or formated. It asked if you want to transfer everything from your boot drive to the new drive and that was it. After it finishes which takes several hours, you shutdown and take the old one out and you're done. Very easy process.

Seagate FreeAgent Desk 500 GB USB 2.0 Desktop External Hard Drive ST305004FDA2E1-RK (Silver) Review

Average Reviews:

(More customer reviews)I do computer repairs.
I normally don't like to see reviews that rate a product with only one star because they got an "out of box failure" but I will have to add myself to the category of people that will not give a product the benefit of a doubt.
I already have a 500gb Maxtor that has worked perfectly. I back up a lot of customers machines in my line of work and like to keep their data for a few months in the event they have a failure, so that was the reason I needed even a larger external hard drive. Also I liked the fact this had an esata connection for my own personal computer.
I plugged the power in and started hearing a double clicking sound. It didn't sound good from my experience with hard drives. I then connected the USB connector. Nothing happened. I waited a while longer and, pulled up the directory and the drive was there. Created a folder and ran across the instructions again. It should have installed the software when the USB was connected.
So I shut it down (and powered down), rebooted my computer and went through the same process again. This time it worked as expected. No clicking sounds... just normal drive activity. It installed the software automatically. Good... I was happy... must have just been a fluke.
A few seconds later I got an error, "delayed write failure" and an explanation the data was not written.
I've never been too impressed with Seagate. I always liked Maxtor (before they were bought out) better with Western Digital in second place.
I decided to give it another chance. I uninstalled the software, ran a scan on the registry and cleaned it up. Started all over again with a new USB port, just to be safe. Exact same thing as my first experience. Started the double clicking sound, pause, then double clicking sound.
Once again, Seagate is not up to prime time. It will probably be a number of years before I try Seagate again. Too bad, because I like the company as I know some people that work there. I think the engineering is top of the line but production must really suffer.
Amazon reviews are so valuable. A quick search found the delayed write failure a common problem when it dies. I took it back (BestBuy) and got a 1 tb Western Digital (My Book). It is very quite... a little larger than the Seagate (about the size of my Maxtor), and much quieter (almost no sound) operation than my Maxtor and Seagate (when it wasn't clicking, but simply accessing data). I've only had the WD for a couple of hours so I can't attest to the software or how it will perform in the future, but I can say that I have been very pleased with the Maxtor. I've had the Maxtor for about a year.
Just looking at the reviews here and my own experience, I would say avoid this product... especially this model.
==============
It's now 2 years later and the Western Digital is still going strong with no problems.

Seagate FreeAgent GoFlex Pro 500 GB USB 2.0 Ultra-Portable External Hard Drive STAD500100 Review

Average Reviews:

(More customer reviews)I was not going to write a review for this product initially. However, I received an email from Amazon advertising this product, along with the other GoFlex drives from Seagate and I saw that this component received a one star rating. After reading the one-star rating, I can tell you all emphatically that the rating is NOT deserved.
First off, the initial customer review information about the dock station is inaccurate, way inaccurate. The HD comes with a dock station (with its own wiring) AND a separate portable connection cable, which truly makes it portable since you can have it set to connect to multiple pcs without breaking down a dockstation connection.
Second the USB 2.0 connection is false since both the dock station and connection cable attach to a pc via USB. Now, neither of the connection cables connect to the HD itself via USB, but thats becuz its connects using SATA type connections you would see on the back of an internal hard drive.
The installation software is built into the HD, so when you connect for the first time to a pc, it prompts you to install the drivers. The software is very easy to manage and pretty much begs you back up your files, although escaping that prompt is so easy, its almost amusing.
The best part of the HD is that its not bulky in the least. I am a lifetime Seagate supporter due to my undying love for Maxtor and the fact that Seagate bought them and for a long while, I have been shopping for portable external drives to use with my hp netbook. This HD is the smallest (although in fairness, its not ipod small) I've seen and fits comfortably in my carrying case.
I cant say that this protable HD is the end-all device becuz honestly, I wont ever compare it to anything else other than what eventually becomes its successor in my household. But, I can say that I am uber happy with this purchase and unless youre an eternal hater of the brand or youre looking for something with the device that you already know it doesnt have when you buy it, you will be happy with your purchase as well.

Seagate FreeAgent GoFlex Home 1TB STAM1000100 Review

Average Reviews:

(More customer reviews)I give this item a 3.5 stars. It looses some stars because it really is not "simple set up" as it states. It takes some time to get it up and your files to back up the first initial time. I was extremely excited to try this product with my home network since we have two Windows PCs (1 XP & 1 Windows 7), and one Mac computer.For each desktop computer, I have installed wired external backup drives. The idea of having ONE back up drive to backup all my files, photos and iTunes music seemed to be like a dream come true. Features a 1TB storage, which is equivalent to 1000GB.
Lets start with the installation. I am using the Windows 7 PC for initial setup. First and most important, you need a Home Network, a wireless router and of course an internet connection. Enclosed in the box is a very basic "Quick Start" guide, I recommend going to the manufacturer's website and downloading the 82 page manual which gives more information. I plugged in power and Ethernet cable to my wireless router. I powered up the drive and inserted the installation CD. I named and registered my drive and added additional user accounts , one for each computer. After that was complete I had to install the software on my other Windows PC and Mac. After I installed the CD on the other PCs, a screen pops up asking to insert the username and password. It's that simple. On my Mac the installation was a little different, but I was able to easily follow the instructions and get it connected using Time Machine with no hassles. One bit of advice for Mac users, if you plan on using Time Machine to back up your files instead of using the optional Memeo Instant Backup, you need to go to Seagate Share Preferences before installing the program on the Mac. Once you are in the preferences page, enable ComputersBackup. Create a password, this password will be used to configure the program when it is installed on your Mac. This information can only be found in the downloaded Users Manual online. Luckily I read the entire manual before attempting to install the Seagate GoFlex. It did take a long, long time to backup all files and folders from all three computers, but I had no bugs or issues. Depending on how many files and folders you are having backed up, it may take all day and night. The program will just run in the background and you do not have to do anything.
The drive will automatically created three folders for each PC account, a public, personal and backup folders. The Seagate Dashboard is the centralized location for all the computer files. This only works with Windows, this is the reason I used my Windows 7 PC as the main system. On the Mac it is Seagate Share and you must use the internet to access the files. You do have the option to use the internet storage base for Windows as well if you like.
There are a few options on how you want to backup your files, I went with the automatic backup. I clicked on instant backups on my menu and the computer shows you the amount of storage that will be included in the backup. If you only what to choose certain files, you can use the advanced settings and drag which files to backup. After clicking "Start Backup", my files started backing up. Whenever I add a new file to the folder or make and changes, the Seagate GoFlex will automatically back up the new file.
Every computer in my home already has a wireless printer, so I really have no use to for the share printer option. But if you do want to use a printer wireless throughout your home network, you must attach the printer via the printer's USB cable to the Seagate GoFlex Drive.
There are many other features and options that can be used, but my primary reason for using this device is to backup the iTunes and photo files on all the computers. When you have thousands of songs and spent several hundreds of dollars on iTunes purchases for every iTunes account on each system, you want to make sure you can access your file in case something terrible happens like the internal hard drive dies. Trust me, I have had this happen to me. I always burn my photos to a CD for added protection, but this way we can share our photos from any computer.
Overall, once you get the unit installed and your files and folders backed up it is extremely easy to use. I guess time will tell if the unit is reliable for retrieving backup files if your system crashes or dies. Hopefully I will not have to find that out! :-)
UPDATE: Sometimes I am not able to gain access to my account online. This is because I use Firefox with a 64-bit operating system and currently "Flash" is not not supported for this OS. I keep getting the "Flash Crash Error Report". However, I can sign in with no troubles using Internet Explorer. So if you have troubles signing into the account online, try a different browser.
If you notice that the drives are not showing under devices in your computer, best thing to do is to unplug it for 15 seconds and then plug it back in to reboot.

Seagate FreeAgent GoFlex 500 GB USB 2.0 Ultra-Portable External Hard Drive STAA500100 (Black) Review

Average Reviews:

(More customer reviews)This drive has a large capacity (by today's standards) and is very portable. It is convenient and highly compatible, not fast, but no slower than others in its class.
I seriously doubt the claim that buying a USB 3.0 adapter for the drive will speed it up noticeably, and certainly not 10x. I discuss this point below. [Update 8/10/10] See below. A discussion in the comments has convinced me that the optional adapters may indeed make a difference for transferring very large files, such as video.
PROS:
large capacity for portable drive by today's standards
small and not too heavy, similar to competitive products
USB 2.0 offers terrific compatibility (Win, Mac, Linux when drivers are available)
alternative interfaces available (eSATA, USB3, Firewire)
USB provides power, so no power supply needed
very standard USB connectors on both ends of cable
compatible with Windows and Mac, and probably Linux (not tested)
[Update] ability to connect directly to TV for playing audio and video without computer via new dock [see below.]
CONS:
misleading claims of value of changing cables [Update: maybe not, see Updates below]
slightly larger and heavier than WD Passport
glossy top attracts fingertips (like Passport)
black case is hard to find in my black computer backpack, but probably other colors will be available in the near future
NEUTRAL:
not fast, not slow, about the same as competitive products, slower than desktop drive or many 3.5" external drives, but far more portable
SPEED
The drive spins at 5400 rpm. This is not as fast as most desktop drives (which are 7200 rpm), but 5400 rpm saves power and runs cooler. It could be that 7200 RPM drives could not be used for an application like this without a power supply. Big drives make great archives, and archive drives don't need to be as fast as the drives that contain your system, programs, and files you are working on.
I copied my audio collection - over 50,000 files totaling 383 GB - to this drive, starting empty, and (separately) to an empty 500 GB WD Passport drive that had been freshly formatted. Both drives took about the same amount of time: a bit under 7 hours, with Windows 7 reporting 16-18 MB/second. The Passport was a little faster, but not enough to make a difference.
CHANGEABLE INTERFACES: QUESTIONABLE VALUE, MISLEADING CLAIMS [see UPDATE in this section]
The included "Personality Cable" allows this drive to be used with USB 2.0. You can get others for USB 3.0 and eSATA, and they CLAIM that this will speed performance by up to 10x. I haven't tried to be certain, but I sincerely doubt that this is true.
You see, USB 2.0 is capable of 57 MB/sec, yet my drive runs at 16-17 MB/sec, so it is performing at only 29% of the maximum USB 2.0 speed. I think the disk itself is the limiting factor. Although eSATA and USB 3.0 are faster interfaces, they can't make a 5400 RPM drive go 10x faster. By comparison, copying files from my internal 7200 rpm drive to an internal 10,000 rpm drive with direct SATA interface maxes out at 66-70 MB/sec, which is about 4x the speed.
By analogy, your car may be capable of 100 mph, but on a lot of roads you're only going to be able to go 25 mph. Putting a faster engine in the car won't help. In this analogy, the disk is the road, and the interface is the car.
Many manufacturers have been very misleading about disk speeds. They often rate the performance as that of the interface, when the device itself is significantly slower. The ONLY time any drive reaches the interface speed is when the data you wanted is already in the cache - that is, you just read it or wrote it, and now you're reading it again. Because the cache is tiny compared to the disk capacity, this is an uncommon situation.
In summary, I doubt the optional interfaces are worth buying.
UPDATE 8/10/10: This section triggered considerable and interesting debate in the comments, and I stand corrected. The upshot is that when transferring "smaller" files (jpg's, mp3's), the transfer rate may be limited by drive performance, but for "large" files (video files, say ~200 MB and larger), sustained reads may indeed mean that the drive is pumping out data faster than the interface, and using a faster interface such as firewire or USB3 could improve performance for transferring large files.
Also, I ordered an eSATA interface kit. For a system with SATA drives, I suspect this interface will be faster than Firewire or USB3, but I'm guessing. I will run some new tests and probably rewrite this review with the results.
CONNECT THIS DRIVE TO YOUR TV!
UPDATE 8/10/10: This is a cool innovation. A dock for this hard drive, which you connect to your TV to allow playback of photos, audio (including SPDIF digital audio), and video (including HD), is now available. See: Seagate FreeAgent Theater+1080P HD Media Player STCEA201-RK. That dock would be handy for people who don't have a computer connected to their home entertainment system but want to play back their media library there.
RELIABILITY
This is the most important feature, and only time will tell. New drives rarely have any problems, and I saw none. The drive has a 3-year warranty, less than some. *Many* years ago I had a Seagate drive fail and I lost data, and I have always held a grudge. With massive changes in technology and manufacturing, this grudge amounts to superstition, but I still normally prefer WD, because they have never failed me.
UPDATE 11 Feb 2011: I started experiencing some serious problems with the drive, amounting to USB failures. At times it would not be recognized; sometimes Windows said it needed to be reformatted; sometimes it did not appear at all; in all cases there were times that I could not access files, and later I could. Then I noticed that I was using a cable that was not the one that shipped with it, but was plug compatible. Now I'm using the original cable. So far, none of these errors. I'll update again if that changes. Lesson: not all USB cables are created equal, even when they are plug compatible.
THE CASE AND WEIGHT
Early drives are always boring black, and they are hard to find in a black computer bag. The comparison drive I used was a red Passport, which is easy to find, and I like the color.
The case is slightly longer than the Passport 1TB, and the drive is a little heavier 9.9 oz vs 7 oz for Passport 1TB, or 41% heavier) , according to the manufacturer's specs.
PRICE
1 TB is currently the largest size for this kind of disk. Starting with the 250 GB drive, these drives have started at the same price when new, and then decrease as larger ones come out, which is a good thing for consumers. Now we get 4x the capacity of the original 250GB drive for the same price.
BOTTOM LINE
Drives like this are now commodity items, with little to differentiate them aside from their size, so you can choose based on color/style or price. Seagate is a name brand and the drive should last.The WD Passport is somewhat lighter, slightly smaller, very slightly faster, and a little more expensive. The product is very good but does not excel, hence 4 stars.
UPDATE: My claim that the drive works for Mac is based on what Seagate says; I did not test that. I have read in other reviews people who have said that it did not work for their Mac. In one case, the review said he was running OS X 10.3.x. Someone suggested that this drive is said to require a later version of OS X, like 10.4.6(?). Please note: I am not a Mac user and my memory of OS X version numbers is not exact. The point is, Mac users might have more luck when the latest OS is installed.
DISCLOSURE: This product was provided to me by Amazon free of charge in return for a review. All of my reviews are written honestly - exactly as I see them.

Big drives make great archives, and archive drives don't need to be as fast as the drives that contain your system, programs, and files you are working on.
I copied my audio collection - over 50,000 files totaling 383 GB - to this drive, starting empty, and (separately) to an empty 500 GB WD Passport drive that had been freshly formatted. Both drives took about the same amount of time: a bit under 7 hours, with Windows 7 reporting 16-18 MB/second. The Passport was a little faster, but not enough to make a difference.
CHANGEABLE INTERFACES: QUESTIONABLE VALUE, MISLEADING CLAIMS [see UPDATE in this section]
The included "Personality Cable" allows this drive to be used with USB 2.0. You can get others for USB 3.0 and eSATA, and they CLAIM that this will speed performance by up to 10x. I haven't tried to be certain, but I sincerely doubt that this is true.
You see, USB 2.0 is capable of 57 MB/sec, yet my drive runs at 16-17 MB/sec, so it is performing at only 29% of the maximum USB 2.0 speed. I think the disk itself is the limiting factor. Although eSATA and USB 3.0 are faster interfaces, they can't make a 5400 RPM drive go 10x faster. By comparison, copying files from my internal 7200 rpm drive to an internal 10,000 rpm drive with direct SATA interface maxes out at 66-70 MB/sec, which is about 4x the speed.
By analogy, your car may be capable of 100 mph, but on a lot of roads you're only going to be able to go 25 mph. Putting a faster engine in the car won't help. In this analogy, the disk is the road, and the interface is the car.
Many manufacturers have been very misleading about disk speeds. They often rate the performance as that of the interface, when the device itself is significantly slower. The ONLY time any drive reaches the interface speed is when the data you wanted is already in the cache - that is, you just read it or wrote it, and now you're reading it again. Because the cache is tiny compared to the disk capacity, this is an uncommon situation.
In summary, I doubt the optional interfaces are worth buying.
UPDATE 8/10/10: This section triggered considerable and interesting debate in the comments, and I stand corrected. The upshot is that when transferring "smaller" files (jpg's, mp3's), the transfer rate may be limited by drive performance, but for "large" files (video files, say ~200 MB and larger), sustained reads may indeed mean that the drive is pumping out data faster than the interface, and using a faster interface such as firewire or USB3 could improve performance for transferring large files.
Also, I ordered an eSATA interface kit. For a system with SATA drives, I suspect this interface will be faster than Firewire or USB3, but I'm guessing. I will run some new tests and probably rewrite this review with the results.
CONNECT THIS DRIVE TO YOUR TV!
UPDATE 8/10/10: This is a cool innovation. A dock for this hard drive, which you connect to your TV to allow playback of photos, audio (including SPDIF digital audio), and video (including HD), is now available. See: Seagate FreeAgent Theater+1080P HD Media Player STCEA201-RK. That dock would be handy for people who don't have a computer connected to their home entertainment system but want to play back their media library there.
RELIABILITY
This is the most important feature, and only time will tell. New drives rarely have any problems, and I saw none. The drive has a 3-year warranty, less than some. *Many* years ago I had a Seagate drive fail and I lost data, and I have always held a grudge. With massive changes in technology and manufacturing, this grudge amounts to superstition, but I still normally prefer WD, because they have never failed me.
UPDATE 11 Feb 2011: I started experiencing some serious problems with the drive, amounting to USB failures. At times it would not be recognized; sometimes Windows said it needed to be reformatted; sometimes it did not appear at all; in all cases there were times that I could not access files, and later I could. Then I noticed that I was using a cable that was not the one that shipped with it, but was plug compatible. Now I'm using the original cable. So far, none of these errors. I'll update again if that changes. Lesson: not all USB cables are created equal, even when they are plug compatible.
THE CASE AND WEIGHT
Early drives are always boring black, and they are hard to find in a black computer bag. The comparison drive I used was a red Passport, which is easy to find, and I like the color.
The case is slightly longer than the Passport 1TB, and the drive is a little heavier 9.9 oz vs 7 oz for Passport 1TB, or 41% heavier) , according to the manufacturer's specs.
PRICE
1 TB is currently the largest size for this kind of disk. Starting with the 250 GB drive, these drives have started at the same price when new, and then decrease as larger ones come out, which is a good thing for consumers. Now we get 4x the capacity of the original 250GB drive for the same price.
BOTTOM LINE
Drives like this are now commodity items, with little to differentiate them aside from their size, so you can choose based on color/style or price. Seagate is a name brand and the drive should last.The WD Passport is somewhat lighter, slightly smaller, very slightly faster, and a little more expensive. The product is very good but does not excel, hence 4 stars.
UPDATE: My claim that the drive works for Mac is based on what Seagate says; I did not test that. I have read in other reviews people who have said that it did not work for their Mac. In one case, the review said he was running OS X 10.3.x. Someone suggested that this drive is said to require a later version of OS X, like 10.4.6(?). Please note: I am not a Mac user and my memory of OS X version numbers is not exact. The point is, Mac users might have more luck when the latest OS is installed.
