In there tech papers it shows....

Specifications 500 GB
Model Number ST3500620AS
Interface SATA NCQ
Cache 16 MBytes
Capacity 500 GB
Guaranteed Sectors 976,773,168
PHYSICAL
Height (max) 26.1 mm (1.028 inches)
Width (max) 101.6 mm (4.010 inches)
Length (max) 146.99 mm (5.787 inches)
Weight (typical) 530 grams (1.168 pounds)
PERFORMANCE
Spindle Speed 7,200 rpm
Average latency 4.16 msec
Random read seek time <1.0 msec
Random write seek time <1.2 msec
RELIABILITY
MTBF 1,200,000 hours
Annual Failure Rate 0.34
POWER
Maximum operating current, DC 2.80 amps

when it shows Random read seek time <1.0 msec does this mean it is going to be unbeleivably fast for random access? In the 7200.10 it is about 8.5ms does this really mean they will be under 1ms access time?

There is a 16MB and 32MB version.

I would have to think that is a typo. I would say it should be <10ms and <12ms....

I have seen that sheet, but the only latency it tells you is the rotational latency of 4.17ms, which is obviously the same for all 7,200 rpm drives.
