Sorry, but you are comparing apples and oranges.
Sure the SATA drives look good on paper, and sure they perform well in
applications without lot's of parrallel IO/s and seeks around the whole disk.
For a more useful comparison regarding fileservers or databaseservers look
into the performance database of storagereview.com:
Thanks.

Select for example "IOMeter File Server - 16 I/O". The top drives are all 15k
SCSI or SAS, followed by 10K SCSI or SAS, followed by the raptors and than
the rest of the SATA drives.
So I see. A 2.5" drive (higher density platters? probably all use the
same density just smaller platters come to think of it...) running at
the highest speed taking the crown. Current SATA versus older 15k RPM
SCSI generation then :D
Sure the SATA drives are still acceptable for a wide range of server
applications, especially since you can use lots and lots because of their
attractive price point.
Yeah.
