Although the Adaptec Threadmark 2.0 is getting quite old, it is still an useful measure of performance when comparing similar drives on the same platform. Here we can see that the IBM 75 GXP manages to beat out the highly rated Maxtor DiamondMax Plus by .3 MB/s. It also comes in slightly lower on CPU utilization that the Maxtor.
I would like to comment that this is one area where the Adaptec Threadmark benchmark is beginning to show its age, as the CPU utilization numbers here are a bit misleading. While the Threadmark numbers are quite high, the IBM 75 GXP uses only about 4.0% CPU utilization during the ZD benchmarks. While we currently do not list the ZD Benchmark CPU utilization scores, they will be available for viewing on all of the drives we have tested, once the new benchmark engine gets put into place.
