Still, I'm not paying $399 for a single HDD. Also, how can they have lower seek times with lower spindle speeds?

thats probably for a 1TB Drive, but of course thats an assumption.

They are slower than the raptor in spindle access times, raptor = 2.99ms, and 7200.11 = 4.16ms. But then there is the seek time (normally 8 to 9ms for most 7200rpm drives), this is what is advertised on most products. On the seagate its advertised as being 8.5ms. The raptors are about 4-5ms i believe.

You have to add up the total times for the overall time (spindle access time + seek time).

7200.11 total would be around 12.7ms then (not too shabby)
The Raptor would be around 7-8ms.

Thats why when you run HDTach seek time test you always get a value of about 13-17ms because advertised HDD's dont take into account the 4.16ms spindle access time for 7200rpm.

But yeah 4x500GB in RAID0+1 would rock and you could sleep like a baby at nite

All the 7200.11 come in 2 or 3 platter versions. I want a single platter 200GB drive! I don't need the storage but I want the speed.
