The X25-M drives referred to are Intel's Mainstream drives, using MLC flash.
The Enterprise grade drives are X25-E, which currently use SLC flash (less
dense, more reliable, much longer lasting/more writes). The expected lifetime
is similar to an Enterprise grade hard drive.
Yes, but they store hardly any data. The X25-M sizes they mention are
getting to the point that you could use them for a data drive.
With wear leveling and zfs you would probably discover that the drive
suddenly starts to wear out all at once once it reaches the end of its
lifetime. Unless drive ages are carefully staggered, or different
types of drives are intentionally used, it might be that data
redundancy does not help. Poof!
