Hey,
I have been having slow write speeds on my Unraid system since I started using it, but recently it has started to bother me a lot. (was Solaris before with the same hardware, speed was much better). So I have started trying to troubleshoot, but don't really know how to.
Doing some basic testing gives my this:
The cache drive:
1073741824 bytes (1.1 GB, 1.0 GiB) copied, 4.80028 s, 224 MB/s
A normal hdd:
1073741824 bytes (1.1 GB, 1.0 GiB) copied, 114.004 s, 9.4 MB/s
Now the cache drive is fine and not relevant, but the normal hdd is not performing well at all.
Doing "hdparm -tT /dev/sdc" gives me:
/dev/sdc:
Timing cached reads: 3412 MB in 2.00 seconds = 1705.82 MB/sec
Timing buffered disk reads: 332 MB in 3.05 seconds = 108.98 MB/sec
Anyone got any ideas on how to troubleshoot and fix this?
Copying large files takes forever at the moment.
Thanks,
activ
