Help w/ RAID

I can't speak for the 850's, but the SATA Edge SSD's we sell at xByte negotiate at 6Gbs and can be mixed with SAS. This works on both the H700 in the R610 and the H710 in the R620. The Edge drives will green light on the front panel but they do show up as non-Dell in open manage. While not supported by Dell, we sell these as a option to get the speed of SSD without the cost of Dell branded SSDs.

The R610 has a SAS 6/iR, not an H700 unfortunately.

Adding to what @todd-at-xByte said, our selection of Edge Drives are a great selection for either 11th or 12th gen dell servers when running the H series raid cards. Your going to be getting 6Gbps throughput on either the H700 series, or the newer H710 series cards as long as your running 6Gbps drives on the backplane. Generally i would never mix SAS and SATA on the same backplane because in my experience i have seen higher failure rates on hard drives being mixed because of the different voltages needed to run both types of drives. To answer your original question @creayt, if the 850 Pros are recognized by the backplane and raid controller, depending on the controller, they will negotiate either 3Gbps (sas 6/ir) or 6Gbps (H-series cards). This is all dependent on them even being recognized though, as they will not have the Dell enterprise firmware on them which is truly needed to be compatible.

Thanks for all of the info, very handy. I read somewhere recently that Dell pushed a firmware update to the controller that took the "Dell certified" restrictions off and lets normal drives work, have you heard anything about that?

To anyone who'se curious: the drives ( all 6 SSDs and the 4 10k SAS HDDs ) are now deployed and all are working/"negotiated" at 6 Gbps. Hooray. The only drawback is that the SSDs are throwing the little alert symbols in open manage, though they appear to be functioning fine and at full speed. Open Manage can't read the power status, etc, and shows them as "non-critical" ( while online ). It's unfortunate.
Pic: RAID 10 of 10ks on the left, Raid 10 of SSDs on the right.

For fun / reference;
840pro 256gb on AMD RAID (AHCI not passing through due to RAID enabled for another array, this is a single drive)

Now throw it into rapid mode and watch those numbers climb.

@creayt Can't unless it's pure AHCI

For comparison, "cheap" sandisk 256gb SSD in my work laptop:
