I’ve read that any TRIM supported SSD prevents this and all SSDs have extra blocks (some more than others) that aren’t being utilized by default and are designed to replace any bad blocks. https://www.truenas.com/community/resources/some-differences-between-raidz-and-mirrors-and-why-we-use-mirrors-for-block-storage.112/ https://www.truenas.com/community/resources/some-differences... seems like ZFS might be special and if you have larger SSDs they will have different cell blocks and be faster because it’s 2x256 boards that can be used concurrently versus 1x256 which will have half the write speed. SSDs also complicate it further with RAM disks, mixed storage (like SLC+TLC/QLC) so the SSDs will be affected more if it’s a cheaper drive with no ram or SLC cache, and smaller sizes with less memory chips. I remember getting the Evo 850 because it had great firmware with ram and SLC cache, it was 3D TLC but it’s speed was still excellent.
