The recent SSD endurance reviews on the review sites seem to show that it takes a long, long, long time before the modern SSD indicates that it has to remap blocks due to errors, except for the Samsung TLC drives, which operate for a long time in this state. Most drives appear to indicate few to no remaps until they are close to the end of their useful life. > Another question is of this buggy TRIM, but I'm afraid this may be > hard fight even with replication and checksumming filesystems > (ZFS/HAMMER/BTRFS). > The problem identified in this article is _NOT_ TRIM support. It's "QUEUED TRIM" support. It's an exotic firmware feature that is BROKEN. Suffice to say, if Windows doesn't exercise an exotic feature in PC hardware, it may not be well tested by anybody! Queued TRIM support is overkill. Regular TRIM support could be achieved by just telling the drive which blocks are to be zeroed during idle times with a stand-alone utility. That is the most reliable way to use TRIM on all drives with the current state-of-the-art
