First, the scsicmd program couldn't figure out the drive geometry, so I inputted those by hand. While this has worked, I'm getting pretty poor performance out of the drive... I'm wondering if I misguessed the rpm info. Write performance seems terrible when writing to the the last partition that resides on the last cylinders. I'm seeing 300 KB/sec write performance, and 600 KB/sec read. (Based on using iostat and some wallclock timings...) Is anyone happily using this drive under BSD? If so, what geometry information did you use? How did you prepare this drive for use? What kind of performance are you seeing? Any help would be greatly appreciated... Thanks in advance!
