Hi folks,
I'm running two different RAID arrays on two different machines. Thing is, the performance stats seem to be wrong on one of them. I expect System 1 to be faster, but actually it's System 2 that is. The specs are:
System 1: Supermicro s1366 mobo, LSI 9265-8i RAID card, 7x 2TB drives and 1x 480GB CacheCade drive, RAID 6.
System 2: Gigabyte s1155 mobo, LSI 9266-8i RAID card, 8x 4TB drives, RAID 6.
Now from System 1, I'm getting 190MB/s read, 190MB/s write.
From System 2, I'm getting 2,400MB/s read and 137MB/s write.
The write figures make sense - they're roughly the same, with a slight boost on that CacheCade-enabled system. But why the enormous discrepancy in read figures?? And why would it be System 1 that is the slow one??
System 1 is much more heavily used, so if anyone knows how I can improve the speed, I'd love to know! Many thanks.
