Hey all - I am putting together an all-flash FreeNAS array using a pool of (10) Samsung PM863 960GB SSDs and (12) Intel S3710 400GB SSDs. I've always used mirrors for SSD pools/RAID, but thinking about RAIDZ (spanned or not) variations... but am concerned about write amplification when using SSDs which ultimately have a limit of DWPD. Anyone have an opinion or information?
The Intel S3710 are high-endurance write disks, so I am thinking of trying RAIDZ2/3 across those (proably 2 since they're only 400GB so rebuild times will zip). But the PM863s are "general purpose" - maybe stick to mirrors? I am just looking for peoples experience - thanks!
