700+ CRC Errors on Samsung 860 SSD in General Support Posted December 19, 2019 I am indeed using Samsung SSDs as cache drives (2x 250GB 860 EVO). I assume there is no need to paste the diagnostics zip anymore, since there is no software fix? If I were to look for a SAS controller for my setup, are there some things I need to look for, compatibility wise? I currently have a 12 drive license, so with the 6 ports on my mobo, a 2 port SAS card (=8 SATA with 'special' cable, right?)should suffice for now.
