The Fireball Plus AS' access time
measures out at a disappointing 13.2 milliseconds, nearly 2 ms greater than that of its predecessor. Subtracting 4.2 milliseconds of rotational latency
yields a measured seek time
of 9.0 milliseconds. Thus, rather than handily beating its spec as its predecessors did, the AS actually comes in a bit behind. Granted, 13.2 milliseconds isn't an awful score... the only drive in the AS' class, the WD400BB
, scores 13.9ms. Even so, the AS fails to meet the lofty expectations set by its precursors.
The Fireball's outer-zone sequential transfer rate of 35.3 MB/sec is decent, though not enough to dethrone the Deskstar 75GXP as the fastest we've measured from an ATA drive. Inner track rates drop to 20.7 MB/sec, somewhat slower than Western Digital's WD400BB.
Let's see how these figures translate into the higher-level WinMarks.
