SSD or RAID Controller Issue?

post #1 of 3
Thread Starter 
Hi guys! I’m having a problem and hoping I can get some help. One of my RAID0’s (I have 3) continues to fail when I run CrystalMark. The other 2 have no issues at all. The RAID0 that I’m referring to is the 4 Mushkin Chrono’s 240GB SSD’s.

When we run CrystalMark to test the speed, it “prepare’s” and then my RAID controller will screen and we get an error message saying that it failed. When we reboot, if we don’t unhook and hook up the cables for the failed SSD, it will show as missing. If we unplug and plug back in, then we can rebuild the RAID with no issues.

We have tested each SSD individually and they seem to be fine. We have also tested the 4 SSD’s in RAID0 on 3 different machine’s and 3 different controller’s, all yielding the same results. We’ve tried different cables, different power supply and as I mentioned completely different machine’s.

*****EDIT***** Just to be clear, the SSD’s are hooked to the RocketRAID 2720SGL. We have tested them in a couple of different machines and on different RAID controllers with different cables. We also feel that the SSD’s are testing slow but close to the same speeds when tested individually (<400mb/s). Also, I just remembered that all but 1 drive drops. So there is only 1 of the 4 that never drop from the RAID, but still tests at the slow speeds.

Any advice? Is it possible we need a firmware update on these brand new SSD’s?
Below is my complete setup. Thanks!

From what I see, the culprit is most likely the raid card. You may want to check that your running the absolute latest fw for your rocket...also it's worth the little extra to be sure all the data cables going to the drives are up to snuff. You may want to try setting up/running the 2 V3's in RO using the rocket just to see if anything crops up.

You can check this review for information that may answer some of your questions: http://www.tweaktown.com/reviews/4306/highpoint_rocketraid_2720sgl_sata_6g_raid_controller_review/index.html

The review tested a single SandForce based SSD like yours on this card and its performance was below that of the Intel SATA III interface, and probably AMD's as well. They also tested with the most forgiving benchmark for SandForce SSD, ATTO, and all benchmarks are different.

I've never heard of Crystal or any storage benchmark program failing when it was run, and I've used some four SSD RAID 0 arrays. Did you try another benchmark? Does the RAID array function normally in use?

This card is a software RAID card, so that may have something to do with the problem. No idea what OS you use, but I would check any power saving options that apply to the PCI-E interface, Windows Power plans have such an option.
