Hey,

So i got a new dedi with 4x1TB In SW RAID10, as the drives are cheap ($15/month/each) I will assume they have been previously used. I have also installed cPanel (No accounts)

avg-cpu: %user %nice %system %iowait %steal %idle 0.28 0.37 0.27 0.23 0.00 98.85

dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync; unlink test

16384+0 records in 16384+0 records out 1073741824 bytes (1.1 GB) copied, 6.19182 s, 173 MB/s

dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync; unlink test

I think 170MB/s with SW Raid10 is good, but confused to why there is 0.23% IO Wait. What do you think?

Cheers
