Tech Level: somewhat high - Ownership: 1 week to 1 month
Pros: 9.5mm height to fit all common laptop configurations. full 5400rpm spindle speed. dual platter, 320GB per platter areal density. nice and quiet in my 15" uMBP.
Cons: i just wish it were a 1TB, 7200rpm drive with 16MB cache and a low 4ms latency. ;)
Other Thoughts: why does this one win against the 750GB drive for the same price?
superior access times through higher areal density per platter and (to a much lesser extent) the faster spindle speed.
the 750GB drive is 12.5mm high due to it's inclusion of a third platter. 750GB divided by 3 platters equals 250GB per platter.
this 640GB drive is 9.5mm and thus only has 2 platters. 640GB divided by 2 platters equals 320GB per platter.
therefore, the increased areal density of the 640GB drive's platters results in reduced seek times due to reduced drive head movement for both reads and writes. to a lesser extent, the 2 platter configuration also allows for the full 5400rpm spindle speed with less vibration than the 750GB's 5200rpm speed; again, this helps with access times.
if you need the space and have the room, get the 750GB. if you want the faster performing drive and a 500GB drive was enough room, the 640GB drive will give you more performance for the buck.

PS3 Compatible 640GB Drive
Reviewed By: Jesse on 10/12/2009
Tech Level: high - Ownership: less than 1 day
This user purchased this item from Newegg
Pros: Standard 9.5mm design, low noise, relatively decent price
Cons: 5,400 rpm, not a huge leap over 500gb for the price
Other Thoughts: From the PS3 perspective, I have high hopes for this drive. I don't forsee the spindle speed as being particularly bothersome, as the stock PS3 hard drive was a 5,400rpm drive as well. I held out on buying a 500gb drive in hopes of a 750gb or 1tb drive coming soon, but my little 60gb drive filled up faster than those two could reach the common 9.5mm height. Actual formatted capacity under the PS3 OS is 596gb, with 529gb available following a bone-stock format under firmware 3.01.

Pros: Great drive so far. I bought this as a secondary storage drive for my Asus G50V laptop and now I'm considering replacing my main drive (320 GB 7,200 rpm western digital) with one as well. 1.2 TB in my laptop would be nice. The sacrifice in speed would be barely noticeable anyway. SSD drives are overrated and I'm not about to sacrifice precious space for the hype, much less the ridiculous price and the firmware bugs they have.
Cons: None that I have seen so far.
Other Thoughts: I work as a systems administrator for a large hosting company and I can assure you that Western Digital is the way to go. I replace bad Seagate drives almost daily and very seldom do I have to replace Western Digital drives unless it's at the very end of it's life cycle. When I get replacement drives back from Seagate, they are always the exact same drive and often fail not long after. Some I have have had to RMA 3-4 times. When I RMA a 3 year old Western Digital drive, they always send the very latest version of that capacity drive, brand new. My desktop (4 x 1TB drives), my laptop (1 x 320 GB and 1 x 640 GB), my wife's laptop (1 x 320 GB) and my netbook (1 x 320 GB) all have Western Digital drives in them, I made sure of that.

Pros: Nice and quiet. Compatible with my 13" Macbook Pro 2009.
Cons: None.
Other Thoughts: The swap to this drive was very easy using cloning software and a SATA USB enclosure I had kicking around. I've been running from this hard drive for a few months, and doing a lot of ripping, decoding, and rendering. No problems whatsoever. Catch this drive on sale and you're golden.
