I have a normal desktop running 2 SSD's in raid 0. Have you read anything about how those get burned out in months?
No. I would be interested in any links to that effect.
"burned out" refers to the inability to do updates. Nand has a limited number of updates before it can no longer do any more.
At that point, read integrity is not compromised.
The number of reads is unlimited. For a normal desktop user, even with heavy usage, it is estimated that there is at least a 10 year lifetime for a MLC ssd. SLC is longer. Such a drive will be long obsolete before you have a problem.
SSD microcode distributes usage balancing updates among the nand chips to improve longevity.
The "trim" command helps by not requiring a read/update sequence when items are deleted.
If a ssd is part of a raid array, the trim command can not be passed to the ssd and extra read/writes will be required. It still will not be enough to hurt longevity. I have tried ssd's in raid-0, and found that there was no apparent benefit to performance. Only synthetic sequential benchmarks looked good.
