I've just finished running Michael Sinz's DiskSpeed v2.0 (from Fish Disk
288) on my systems, and I thought that others might be interested in the
results.
My main system is an A2000 with an A2620, Hardframe controller, and CDC
Wren III 150M drive. This was also used as the "remote" system for the
Parallel Port Network (ParNet) tests. An A500 with 1M of RAM & 2 floppies
was used for the "local" system on the ParNet tests, and the floppy tests.
I didn't really attempt any complete comparisons of the different test
intensities on all the devices (especially floppies, that could take
days!), but I have run at least a couple of different intensities on most
of the devices.
One point of interest is that fragmentation cuts the speed in half on the
hard drive tests. And for some reason, the remote hard drive is actually
faster through the ParNet than the remote RAM disk.
Some notes on DiskSpeed: There is a trivial bug in the labeling of the
results; the Create, Write, and Read rows all get labeled "Create". I've
corrected this by hand in the results included below, and e-mailed Michael
about it. Michael claims that DiskSpeed is more accurate than the rest of
the disk performance benchmarks, and from the results I've seen, I believe
him. I've run ALL of the benchmarks I can find, and there is a wide variety
of results, but DiskSpeed compares closely to the one I trust the most,
Joanne Dow's rewrite of DiskPerf.
My DiskPerf benchmarking was going to be part of Christian Balzer's massive
hard drive review/comparison, but I've never seen it posted (Christian ?),
so I'll post my rather lengthy article after this one.
Ok, here are the numbers. HD tests are with FFS, floppy tests with OFS.
