Fast and initially stable. Have three RAID 1 pairs with one each of these plus a HDD in each raid set. Overall works great as I get 25-45 % better performance over 2 HDDs. Except for writes but that’s expected. So I get the speed of SSD reads and the reliability of a spinning platter.

Maybe this is a batch issue but one day on a reboot Windows booted to a recovery screen. All windows options failed at that point including troubleshooting as it couldn’t diagnose any issues. So unplug all drives except the boot disks. Now it boots. Installing just the HHDs in the raids and the system boots. Install a SSD cable and I get only the recovery screen. One SSD failed but a second one failed 48 hours later. There are different VMs on each raid pair but some VMs get substantially less booting and use. Fortunately the IPR kicked in and after a tech checkout at Mem Exp I have received 2 new SSDs. Hoping the 3rd one stays stable.

Very strange that a fault / failure on a SSD (maybe a Samsung problem?) causes all SATA ports to hang the system. The BIOS cautions about mixed raid (and so it should) but is happy to allow the config and for the last 8 months it has worked perfectly. HDDs usually show minor issues as they degrade but rarely outright fail. I’ve just found SSDs just fail. Thanks to the HDDs I haven’t lost any data. And yes I do do backups but that’s not the point here. Samsung gets 1 star and Mem Exp gets 5.
