Enterprise ssd - why not just use a raid of cheap consumer ones? It's not like you can realistically wear them out, and even if you do then you could buy 5 for the cost of one enterprise one.
With the old spinning rust disks, the enterprise ones have tler - time limited error recovery meant that the raid array would not wait for repeated read attempts from a bad block - up to 2 minutes as a consumer level drive. It would wait for a maximum of 7 seconds before failing, and the raid controller would simply read that block from the mirror instead.
But enterprise ssds? Seems to mostly be higher write cycles tolerance, and even on consumer level ssds the endurance is "lots"
