Thanks, that's what I did. It works fine (I'm using a SOYO 5EHM
motherboard with an AMD K6-2/200). Performance is excellent; bonnie
gives:
-------Sequential Output-------- ---Sequential Input-- --Random--
-Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks---
MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU
svax32if 100 10336 95.5 14246 57.3 5733 35.9 11372 95.4 17128 57.0 147.9 3.3
that's 17MB/s for block reads (this varies quite a bit depending on
the physical position on the disk). Not bad for a disk costing £165
for 13.5GB. On the other hand the system really grinds to a halt while
the benchmark is running.
Incidentally, I tried bonnie on an MSDOS partition (just because it's at
the outside of the disk) and the result was:
svax32im 100 8940 89.2 12984 76.1 473 2.8 9108 92.1 15584 86.4 76.3 48.8
Note the abysmal rewrite speed!
