Got this new drive, there doesnt seem to be any benchmarks or reviews yet so i though i would post this.

Cant figure out if these are 500gb per platter, they seem a little slow, the samsung f3 is much faster in sequential benchmarks.

640GB cannot have 500GB platters; a 500GB-platter drive either has capacities of 500GB (1 platter), 1000GB, 1500GB or 2000GB (4 platters).

640GB uses 320GB platters which is one generation below the 500GB-per-platter drives.

Yes it can, it could be the same drive as a 1000gb, 2x500gb platters but with 180gb disabled per platter.

Yeah sure, and AMD is selling 64-core CPUs with 60 cores disabled; so your quadcore is actually 64-cores!

While it is all theoretically possible, of course HDD manufacturers are not going to waste their highest-gen platters. So you will never find a 640GB drive with 500GB platters in reality. Doing so would be utterly stupid, and not very profitable.

AMD are actually selling triple cores which actually have 4 cores, and some people have successfully re-enabled them.

Western digital has the WD8000AARS 800gb drive which is 500gb per platter (same as the WD10EARS 1000gb). Also its priced the same as the WD6402AAEX so its probably is as profitable as the WD8000AARS.

The Phenom dualcores are quadcores in fact too, but my point was that no manufacturer will waste its own products with gross inefficiency.

You can count on any 500GB disk to come in 500/1000/1500/2000 capacities. Now if we would get 666GB platters, that would mean 3-platter 2TB disks, or 2.5TB with 4 platters. In the latter case, some capacity is wasted but only minor. And by removing the capacity in the inner tracks you remove the slower parts of the HDD which aren't really missed after all. So this might make sense and is not inefficient at all.

Hey does anyone else have this drive now? Just wondering how you like the performance and noise on it.
