It all comes down to speed the 10K has faster access time. A common practice is to run two raptors in Raid 0. which can cut the access time even more.
10000 RPM
Brand: Western Digital
Series: Raptor
Performance
Capacity 36GB
RPM 10,000 RPM
Cache 16MB
Average Seek Time 4.6ms
Average Write Time 5.2ms
Average Latency 2.99ms
7200 RPM
Brand Western Digital
Model WD1600YS
Performance
Interface SATA 3.0Gb/s
Capacity 160GB
RPM 7200 RPM
Cache 16MB
Average Seek Time 8.7ms
Average Latency 4.2ms
Note: 10K SATA drives come with 16MB cache, 10K SCSI 320 come with 8MB.

the 10,000 rpm drive would be faster but not by leaps and bounds

the price between the two drives would be a better factor to focus on


example


Drive:A is 10,000 RPM's and 160gig with 8mb cache in size for $80.00


Drive B: is 7,200 Rpms and 250 gigs in size w/16mb cache for $80.00


Drive A is faster but drive B is the better deal and more desirable
