Yeah, The new firmwares really opened up the LSI Controller.
Try to do this in Command prompt as admin and show me your numbers Moose ( winsat disk)
here are my numbers before one of my SSDs went bad and i had to get an RMA.
This is a 1mb stripe size
> Disk Sequential 64.0 Read 1933.80 MB/s 7.9
> Disk Random 16.0 Read 207.80 MB/s 7.8
> Responsiveness: Average IO Rate 0.29 ms/IO 7.9
> Responsiveness: Grouped IOs 5.50 units 7.9
> Responsiveness: Long IOs 1.57 units 7.9
> Responsiveness: Overall 8.62 units 7.9
> Responsiveness: PenaltyFactor 0.0
> Disk Sequential 64.0 Write 1244.74 MB/s 7.9
> Average Read Time with Sequential Writes 0.284 ms 7.9
> Latency: 95th Percentile 0.683 ms 7.9
> Latency: Maximum 38.740 ms 7.9
> Average Read Time with Random Writes 0.446 ms 7.9
> Total Run Time 00:00:56.94
The funny thing is like an hour before one of my drives went back and with the new LSI firmware i had these numbers
> Disk Sequential 64.0 Read 2496.89 MB/s 7.9
> Disk Random 16.0 Read 212.08 MB/s 7.8
> Responsiveness: Average IO Rate 0.36 ms/IO 7.9
> Responsiveness: Grouped IOs 6.10 units 7.8
> Responsiveness: Long IOs 2.50 units 7.9
> Responsiveness: Overall 15.22 units 7.9
> Responsiveness: PenaltyFactor 0.0
> Disk Sequential 64.0 Write 1226.32 MB/s 7.9
> Average Read Time with Sequential Writes 0.287 ms 7.9
> Latency: 95th Percentile 0.699 ms 7.9
> Latency: Maximum 38.129 ms 7.9
> Average Read Time with Random Writes 0.430 ms 7.9
> Total Run Time 00:00:57.05
Now i dont know how accurate the second benchmark is because my drive died like an hour afterward so who knows!
Check this guys post out.
Computard on the OCZ forums is badass when it comes to raid cards and advice. He has tested them all :P. Maybe you can pick something up in the middle of that thread about his take on stripe sizes and speed your array up a bit!
http://www.ocztechnologyf...466-LSI-9260-8i/page79 His post on the stripe matter is really worth a read.
