Low level tests using ZD's WinBench 99
show that, in outer zones
, the DiamondMax 80 clocks in with a sequential transfer rate
of just under 30 MB/sec... about 10% slower than the IBM Deskstar 40GV
. The DM80, however, maintains its transfer rate more proficiently as we advance inwards through the cylinders
rates come in at 17.5 MB/sec, 17% faster than IBM's unit.
WB99 measures the DM80's access time at 15.5 milliseconds... subtracting a 5400 RPM rotational latency of about 5.5 milliseconds, this figure comes in a millisecond higher than Maxtor's specification of 9 ms seek time. Interestingly, this figure is also a millisecond higher than that of its predecessor, the DiamondMax 60. Maxtor indicates that it scaled back its next-generation 7200 RPM unit, the forthcoming DiamondMax Plus 45, due to concerns of combining high areal densities with swift seek times. The three-platter version of the DM80 may turn in slightly faster seeks.
