Not sure that anyone will be able to help you get non-certified drives to work correctly.  There have been several reported issues with off-the-shelf/consumer SSD's on Dell controllers.  The firmware simply doesn't have all the answers to the controller requests ... in some cases, the drives don't even show up on the controller, in some cases, they show up but can't be configured, in some cases, they randomly fall offline, and in every case I've seen, they show erroneous status LED's (showing offline when they are online - a sign they cannot effectively communicate with the controller).  You may consider trying to leave the drives unconfigured (no RAID) and letting Windows mirror them ... maybe the problem won't be present in non-RAID mode. The H310 is a very low-end controller, so expectations should be adjusted accordingly (performance, flexibility, reliability, compatibility, etc.).   What problems exactly are you having with your conventional HDD?
Hoping someone here can help me out.  I have been banging my head trying to figure this out and to no avail. We have a new t420 with a Perc 310 running 2008 R2.  I ordered the computer from Dell with a single 2.5" 7200RPM SATA drive (500gb) and a 16 hot swappable front panel.  We wanted to add more drives to the system mostly SSDs that the customer owns.  There are a total of 4 Samsung 840 SSDs.  To install I found a seller of some second hand caddies as Dell would not sell me any caddies.  I also install two regular hard drives (2.5) into the system one as a mirror (raid 1) for the drive that I ordered the server with and the other as a backup for the mirror OS drives. Problems started when I attempted to setup windows backup to backup the OS mirror to the other hard drive in the bay.  It failed saying it had an I/O error.  I thought at first that perhaps I had a bad hard drive out of the box and setup the backup to go to an external hard drive which has been working fine while I work on a replacement drive. That said, I dont think I actually have a bad drive as yesterday we started having trouble with Quickbooks Database Server Manager crashing on the server and throwing I/O errors in the event viewer.  These quickbooks files were stored on one of the 4 SSDs I installed.  I did a good deal of testing to get QUickbooks to be stable but was only successful when I moved it to the actually C drive of the server and off the SSDs.   Also I have had trouble with CrashPlan which is a backup software we were using for cloud backup.  It crashes as well when it attempts to backup the SSDs.  This software is normally very stable so again odd.  Unfortuntely, it is not logging errors that I can point to I/O. All that said, I spoke with Dell Pro Support and the only thing they can point to is that the drives I have installed after the fact are not "certified" and are therefore showing up as explanation points in the RAID Manager OpenManage.  Basically, I am stuck.  Not sure if anyone else has had issues like this before or can give me any direction on how to troubleshoot. I really would like them to be able to use these SSDs but at this point I am unsure what else to do.  That said, I do not believe it to be just the SSDs as I am also having trouble with the conventional hard drive that was supposed to be a backup to the RAID.  It is a WD Black 500GB. Thanks in advance for your help.
