HDTach seems to be a benchmark that many like for comparisons. You can download a copy from http://www.tcdlabs.com This program can give you indications of speed, as well as CPU load.

Hi all, Not long ago I installed an Abit BE-6II Motherboard with Highpoint ATA 66 controllers. My primary drive (WD 10 Gig Caviar I think it is) is attached to these controllers while my second drive is attached to the slower ATA 33 controllers. The BIOS ? screen at boot up specifically for the highpoint controllers says that the primary drive is running in UMDA mode 4 but what's a good way to verify that my hard drives are running at the speed they're suppose to. Thanks for any info., Bill Nussbaumer PCBUILD's List Owner's: Bob Wright<[log in to unmask]> Drew Dunn<[log in to unmask]>
