WinBench 99 measures the P20's
access time at 13.5 milliseconds, just wee bit higher than a the tightly grouped trio of the
Maxtor DiamondMax Plus 60, the
Quantum Fireball Plus AS, and the
Western Digital WD800BB. This in turn results in an access time significantly higher than
IBM's Deskstar 60GXP and significantly lower than
Seagate's Barracuda ATA III. Subtracting the average
rotational latency of 4.2 milliseconds for 7200 RPM operation yields a measured seek time of 9.2 milliseconds... slightly off the mark.
An outer-zone transfer rate of 34.5 MB/sec places the P20 at the lower end of the pack. Our sample exhibits some dips in the transfer rate graph indicative of remapped sectors... these shouldn't affect performance tests, however.
