Hello,
I recently purchased 24x ST32000444SS to use on my areca 1680ix-24 and I built a 23 drive + 1 hotspare raid 6 array it initialized in 6 hours and I did some testing with dd and the write speed was around 1.1GB/s however the read speed was only 300-400MB/s.
I did some further testing and broke the raidset and created a 5 drive raid 0 and read/writes were around 700MB/s.
So it seems that having a lot of the ST32000444SS drives on a single raidset/volume causes the read speeds to suffer dramatically.
I also created enough different raidsets/volumes for 5 drives in raid 0 to test all the drives and all were able to get around 700MB/s read/writes.
I should also note that I did not have this problem with my previous ST31000340NS sata drives.
Any ideas? Thanks
