So, I have the raid working with the new drives, and new controller, but it seems slower than the single disk. Ive done some looking, and some benchmarking... these are my findings/results.
hda is running at ata100 instead of 133 (udma5) hde and g are 133 (controller says so in dmesg), and hdparm shows udma6 The drives are 133, and the hda controller should be 133... Ive tried 3 programs to bench the drive/array hdparm bonnie++ tiotest I ran tiotest with 512M, 1G, 2G test block sizes, and got very simular results. Raid Single 512 21.770 MB/s 25.942 MB/s 1024 21.771 MB/s 24.780 MB/s 2048 21.770 MB/s 26.307 MB/s It would apear my single drive is about 20% faster than my raid!!! Bonnie++ shows the single disk at about 29 MB/s, and 23MB/s for the raid. heres the hdparm info: [EMAIL PROTECTED]:~# hdparm -Tt /dev/hda /dev/hda: Timing buffer-cache reads: 2928 MB in 2.00 seconds = 1463.49 MB/sec Timing buffered disk reads: 170 MB in 3.01 seconds = 56.41 MB/sec /dev/md0: Timing buffer-cache reads: 3288 MB in 2.00 seconds = 1643.43 MB/sec Timing buffered disk reads: 150 MB in 3.01 seconds = 49.91 MB/sec So, at this point, It looks like my raid is sucking. Id get better performance as regular single drives than I am with this raid setup. any ideas on how I can get this working right?
