Black vs. Blue
- Pros: Some are comparing this drive to the "Blue" WD6400AAKS, and though they are the same size there are differences. The Blue has 16MB cache vs. 32MB. In real life this actually doesn't make a big difference by itself. What the Black gives you to go along with double the cache is two microprocessors instead of one. The Black also has two motor mounts for stability, one on each end of the shaft, whereas the Blue has only one. All in all the differences in performance aren't going to be earth shattering for most every day use. Large transfers and mixed file access will favor the Black, but it isn't by a huge amount.
- Cons: None, mine is still running flawlessly.
- Other Thoughts: So what does the extra 15 bucks give you? For starters you get 5 years warranty rather than 3. The better construction should translate to longer life, but it is too new to know for sure at this point. If you think a better warranty, bigger cache, dual processors, and sturdier construction, and a little better performance is worth $15 then opt for this drive, otherwise get the WD6400AAKS which is a fine drive on its own merits.
Lightning in a Bottle
- Pros: Quiet
Cool
Lightning Fast
This drive is FASTER than my old WD Raptor WD1500ADFD and has the benchmark numbers from HD Tune 3.10 to prove it.
Vista Ultimate x64 SP1 (fresh install with all updates and drivers)
Intel D975XBX2 w/Intel Core 2 Duo E6600
FYI: this drive will format out to 596GB of usable space under NTFS

From the end of my BIOS POST screen until I'm at my desktop with a functioning network connection is just over 40 seconds.
EXCELLENT!
Newegg now seems to be shipping this OEM drive wrapped in bubble wrap, so thank you Newegg for listening to your customers on how OEM drives should be shipped!
- Cons: None
- Other Thoughts: If you are looking for a very fast hard drive and don't have the budget for a Western Digital Velociraptor or a good SSD, then this drive is your only other rational choice.
This drive is much easier to live with than my previous second generation Raptor (quieter, cooler, and 4x the space) and feels just as fast, if not slightly faster.
This drive is a steal at this price point, so why not buy two?

Excellent!
- Pros: Runs flawlessly so far. No problems. Loads everything quick. Decent amount of space for gamers etc. Unrars in a flash... about 200 fps while encoding movies.
- Cons: none so far.
- Other Thoughts: maybe should of got a little bit bigger drive. But Black is top notch.
Hard Drive
- Pros: The drive isn't loud and seems pretty fast. No complaints.
- Cons: None
Awesome!!
- Pros: 640GB, 32MB Cache, Sata II. This hard drive unlike my other that was DOA fired right up. Inexpensive for the quality drive you get. I love it and recommend you buy it.
- Cons: The packaging of the drive lacks attention. It could have been packaged a little better. That is how my last drive became DOA!
- Other Thoughts: I have been a WD fan for years and will continue to be one.
