Absolutely. I took QuickBench, available as part of Intech HD SpeedTools, and did benchmark one of my CF cards w/ AztecMonster again:
For reference, here is the FWB benchmark result, taken 4 weeks ago:
The results for both sustained read and sustained write are more or less the same. Random read and random write are comparable, too. Please note that the FWB diagram has a linear x-axis, whereas the QuickBench diagram has a logarithmic one.
But guess what? Following JDW's thought I just bought the Intech HD SpeedTools and re-initialized the CF card with HD SpeedTools, thus deleting the FWB driver with the HDST driver. Look at that:
Lessons learned so far:
• Benchmarks made with FWB HDT and with Intech QuickBench show similar results. So presumably it's not the benchmark tool itself introducing the problem.
• CF card shows dramatically better read performance when formatted with Intech HDST. Regarding write performance, both FWB HDT and Intech HDST deliver the same, disappointing results.
For comparison, here are the QuickBench results of a Quantum Fireball 1280S real spinning platter hard disk.
