Pros: reliable for over six months so far

Cons: none so far

Other Thoughts: Purchased this for my PC i built about six months ago as my main drive. I also own the 1TB version that i ran in my old PC for over a year and now use it as my storage drive in my new PC. Good all around drive for gaming or anything else.

Pros: It works and is faster than my old 80GB WD BLUE SATA 3.0 GB/sec drive. If I had a put a figure on it, I'd say, depending on what you're doing, it can be anywhere from 20% to even 50% faster.

Both my BLACK and BLUE 640GB WD drives were anywhere from 20% to 50% faster than my old 80GB WD BLUE SATA 3.0 GB/sec drive.

Cons: I also bought a Western Digital Caviar Blue WD6400AAKS 640GB 7200 RPM 16MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive (N82E16822136218). When I formatted both of them (not the quick format option), by the time the BLUE hard drive was finished, the BLACK one was at 90% only.

After that, I ran some tests and copied some files from my C: drive (80GB WD drive) to my other two drives, at first it appeared that the BLUE drive was a few seconds faster copying about a GB of data. After some subsequent tests, it appeared they were very close.

Maybe it's just coincidence or something but it seems the BLUE drives are faster.

Pros: Running these in a raid zero config, getting about 212 mb/s throughput.

Cheap, fast and reliable, I always buy drives with 5 year warrantys

Cons: None

Other Thoughts: Great drive on the cheap, in raid zero as fast as SSD drives throughput, with out the cost and tiny storage size.

buy em.

Pros: Wester Digital has never let me Down. The black series does boot faster and has been faster period. The price per storage capacity is excellent

Cons: None to date.

Other Thoughts: It is not a digital drive, but then again it did not cost an arm and a leg!

Pros: It's one of the best hard drives for this price range. Worked out of the box as it should and have no issues with it.

Packaging was exaggeratedly good. It came wrapped in tons of layers of bubble wrap and paper.

Cons: It doesn't have wings.

Other Thoughts: We all know that the hard drive is the bottleneck of any system today. My score is around 7.5 for everything except my hardrive, which is 5.9.

If you have the money, just get like a 128gb SSD and put your OS and Apps on it. Combine that with this Black Caviar hard drive, and your set.

Pros: CAVIAR BLUE IS FASTER THAN CAVIAR BLACK AS FOR MY EXPERIENCE.

Cons: the speeding is not fast as caviar BLUE....

Other Thoughts: Now I'm using all caviar BLUE 640G RAID0

very good

Pros: It works. No problems installing Windows 7. Reasonably quick.

Cons: It's noisy. Like late-90's hard drive noisy. It also vibrates more than I'd care for - I can feel it in my keyboard, mouse, and desk surface at all times. It's sorta got a "rough around the edges" quality to it because of this.

Also, it lags now and again - where there will be a brief pause in my activity because of the drive's operations. This is something that the drive on my other computer (a S**sung) does not do.

Other Thoughts: Overall: 3 Eggs

Not quite as fast as I'd expect. Only pulled a WEI of 5.9, but it's not a SSD, so what can be expected?

Honestly, it would seem that the WD Black series and maybe the WD brand is altogether overrated. Even with the minor annoyances, this is still, so far, a solid hard drive. Some sources would also suggest WD drives last longer than those from other manufacturers, too. If this is indeed the case, then I will be able to forgive this drive's shortcomings in the long run. Let's hope.

Pros: Neutral odor.

Cons: CrystalDiskInfo shows 'Caution' with Current Pending Sector Count increasing every hour. It is now up to 838 having started today at 12 or so. WDC's test run time was first estimated at 5 hours and then keep increasing as the test ran. I stopped the test when it estimated 34 hours remaining. WDC Tech Support seemed to think that this length of test was OK. On restart the test duration is now estimated at 72 hours!

Other Thoughts: WDC Tech Support person seemed incompetent.

Pros: look my best friend has Two 300 GB Veliciraptors in a Raid 0 and this is a good set up he is pulling a 6.2 on windows performance test. Get this he spent $400.00 for them to. I have three of these drives I caught on sale for 54.99 and have them in Raid Zero as well and I am pulling a 6.3 performance rating on Windows 7 Ultimate same OS as my friend and I only spent $144.00 these Drives are the best for the Money I had one Veliciraptor and returned it tripled my space and performance 19200 GB now instead of 300 Can't beat it Rideout Computer Engineer these Drives are nice trust me

Cons: I am very satisfied to date nothing negative to report about these Drives no failure nothing

Other Thoughts: These Drives out perform Raptors I have owned both and have seen PC MARK test on both granted Raptors spin at 10,000 RPM but the cashe is 16 MB these Drives are 7200 RPM and 32 MB of Cashe they cancel out These dives for $250.00 less with triple the space so worth it

Pros: Super silent if AAM is tweaked

Super fast load times as expected

Cons: Must google for AAM and download it and tweak to quiet mode to make drive quiet

Quiet mode will lower performance by 1 to 5% ish.
