Hmmmm...Lies??

I haven't had any problems with Seagate, and my brother hasn't had problems with Western Digital, so just go with what you think is better. At this point there's not much difference between them.

Im running 3x500GB Seagate ST3500320AS in Raid 0 and i dont see or feel any differnce compared to the 2x300GB VelociRaptors in Raid 0 that i just sold.And the benchmarks were very close also.Except acess times with the seagates around 11ns and the raptors were at 6.9ns.But i cant tell the differnce with my eyes.Oh and Window's 7 scored my Raptors at 5.9 and the seagates get the same score.But im happy with my seagates or i would have kept the raptors.Im still one of the frist people on the servers in most games

Neither.

Get a Samsung F3. They are slightly faster than the Seagate .12s, and much cheaper. The random access is slightly lower than the 640GB Black drives, but the 1TB F3 costs the same as the 640GB Black. Once short stroked to 640GB, the F3 is faster overall. It is therefore the better drive in all respects.

Don't go for the 500GB drive - get the 1TB. It is not much more expensive (~$80), but is a much better buy than the 640GB WD for ~$75.

I am very happy with my "infamous" 7200.11's, which were about the fastest out there when I bought them. I also have WD, Samsung, Hitachi..

I buy what meets my needs at the time..

^^ This.

Either of the current-gen performance drives (the Seagate .12s or the Samsung F3s) will be indistinguishable in use. Even the last-gen Blacks will be hard to tell from the newer drives.

But the Samsungs are the cheapest/best value of the lot right now, which is why I recommend them currently for those looking to buy new disks. They are not really a worthwhile upgrade for anyone whos disks are less than ~2 years old, and probably won't really make a noticeable difference for anyone with disks less than 4 years old.

In the future my recommended drive may change. And the future is never far away in the IT world...
