You're too funny!When you leave for a month the rats come in and take over
Trust me....I'm totally on board (excuse the pun) with using a HW RAID controller. I'm just a bit surprised that a dual core 800MHz ROC would be a bit of a bottleneck when it should be doing very little other than passing the reads and writes through. Otherwise, I'd think we'd have to worry about the speed/power of the SSD controller. My guess is the LSI firmware has a bug and is doing more processing than it should be in this case.RAID0, a multi Ghz CPU on a Mobo can do this faster than a few 100 Mhz ROC
As RAID0 requires no real processing, just a matter of storing data in a stripe across drives
HW controllers like the SAS9260 are for enterprise use ie SAS drives which are slower but more reliable.
Mobo controller can't do SAS
Mobo controller can't do more than 2x SATA3 (Z87 can do 6) off the controller for RAID
Mobo controller has no HW caching
Mobo controller has no error checking correcting
Mobo controller can't do RAID6, or spanned RAID5 (ie 50/60)
Try and take a Mobo created RAID set to another computer, LSI RAID will work on all LSI RAID cards.
