Hello, I am new to intel forums and looking for some information.I just finished installing latest firmware and Windows Ultimate 64 bit along with all drivers. I ran a bench for my RAID 0 performance and something does not add up right. I should be getting over 800 mb read but I am not getting those type of numbers. To bench my raid I used HD Tune Pro 4.60 and these are the results.
Minimum = 555.4 MB/s
Maximum = 697.3 MB/s
Average = 621.0 MB/s
Access Time = 0.082 ms
Burst Rate = 5662.9 MB/s
CPU usage = 3.0 %
System Specs
I7 950 Bloomfield D0 @ 4.21
EVGA 4 Way Classified Bios.82
Corsair Ram CMT6GX3M3A2000C8 12 GB total @ 8-9-8-24-88 2T 2000 mhz
Corsair AX 1200 PSU
EVGA GTX 570 HD 3x
Sound Blaster X-Fi fatality pci-e
Intel X -25 M 80 GB 4x in Raid 0 mode
Cpu is water cooled along with my motherboards NB,SB and Mosfet. Not sure what could be the bottleneck

Hello and thank you for the replies, I am using the most recent updated drivers for ICH10 raid controller and only option I have toggled is
Write Back Cache : Enabled in my Intel Rapid Storage Technology application. Is there any other setting I should look in to ?
Here is a screenshot of HD Tune Pro stats.
Intel X25-M SSDSA2MH080G2K5 2.5" 80GB SATA II MLC Internal Solid State Drive ( 4X )Sequential Access - Read up to 250 Mb/s on each driveForgot to mention I am also using latest firmware for each ssd drive. On a side note which raid controller would you recommend ?04-28-2011 08:35 PM
Parsec, I am not sure if Intel prints the peak bandwidth of the ICH10R anywhere. However, I have seen that 600-700MB/s bottleneck occur on multiple benchmarks over the years.
Certified, I can really make direct recommendations. However, you would be looking at server hardware RAID controllers with dedicated RAM and CPU. The newer models specifically have support for SSDs. Note that RAID0 provides sequential performance gains.for the most part. Your random performance is probably about the same. Unless you have specific workloads that do large (1GB+) sequential read/writes, the benefit is questionable.
