The Protégé's measured access time
of 18.1 milliseconds certainly won't win any awards. Its right on par with Quantum's Fireball lct15
... and the Fireball features a 4400 RPM spindle speed! That said, 18.1 ms is an expected figure. Adding 5.6 milliseconds of rotational latency
to the specified seek time
of 12.1 milliseconds yields a theoretical average access time of 17.7 ms... proportionately speaking, the Protégé isn't far off the mark.
A maximum sequential transfer rate of 25.6 MB/sec is also decidedly mediocre. While the WD manages a 5 MB/sec lead over the Fireball lct15, it trails offerings from competitors such as Maxtor and Seagate.
