Hi people,
I am experiencing a poor sequental write performance with 3-disk RAID5 array on 3Ware 7500-8 - it is only 11-12 MB/s. Under Win2000 i get 30-35 MB/s from the same array.
I have used different methods: dd, iometer and "copy /dev/zero tstfile" - they all give me the same low figures (11-12 MB/s).
Are you using ext3 in the default journaling mode? If so try writeback journaling, or just use reiserfs.
