Exillis Posted March 23, 2009 Share Posted March 23, 2009 I just measured the performance of 4 Corsair SSD in RAID0 running off the motherboard controller (ICH10R chipset). These drives are impressive (320MB/s write and 389MB/s read) and it appears I'm getting decent scalability on both read and write. The performance is very consistent. I'll buy a couple more to fill the remaining slots on the backplane. I think at that point I may need to go with a hardware RAID solution. I'd like to measure peak CPU utilization across the test but it doesn't look like ATTO has that capability. Can anyone suggest another benchmarking tool?

FEAR6655 Posted March 23, 2009 Share Posted March 23, 2009 I use HDTune which has a really good benchmark with CPU usage. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted March 23, 2009 Corsair Employee Share Posted March 23, 2009 Also Please try the HD-Bench software or Sysoft Sandra to test the performance. Link to comment Share on other sites More sharing options...
Exillis Posted March 24, 2009 Author Share Posted March 24, 2009 I use HDTune which has a really good benchmark with CPU usage. Thanks, here are the results. Can anyone explain why the read throughput spiked at the end of the test and stayed there? Link to comment Share on other sites More sharing options...

Exillis Posted March 24, 2009 Author Share Posted March 24, 2009 RAM GUY, Do you know why the throughput spiked (and then stabilized!) torward the end of the HD Tune benchmark? I did not see this behavior in the ATTO benchmark. What is the cause of this behavior? The average of the first phase is around 389MB/s, so it looks like these drives are capable of ~97MB/s. Also, what is the burst rate? I can't believe I'm measuring over 1GB/s burst. Looks like CPU peak is just below 4%. A hardware RAID controller would likely bring that down to 2%. Check out the consistency...very nice. That is more important to me than a higher peak throughput. Link to comment Share on other sites More sharing options...

I did not see this behavior in the ATTO benchmark. What is the cause of this behavior? A: More than likely its just a bug or anomaly in the software. Test the drive with a few different application to get a better average. Also, what is the burst rate? I can't believe I'm measuring over 1GB/s burst. A: Burst rate is harder to calculate with a raid setup because the burst rate of the drives and what the controller can cache will all affect this. Looks like CPU peak is just below 4%. A hardware RAID controller would likely bring that down to 2% A: I would suspect that would change noticeably with the brand of controller you use but yes I would agree for the most part. Check out the consistency...very nice. That is more important to me than a higher peak throughput A: Agreed the consistent performance is what you should be looking at!

Corsair Employee RAM GUY Posted April 28, 2009 Corsair Employee Share Posted April 28, 2009 I was going to say they seemed a bit slow for a Raid setup. Link to comment Share on other sites More sharing options...
