SSD Wear Endurance
Discussions focus on the limited write cycles and endurance of SSDs using NAND flash, including wear-leveling mechanisms by controllers, read/write degradation, and concerns over lifespan versus practical usage.

Modern SSD controllers should be doing wear-leveling such that you don't need to worry about this.
SSDs are only weared by writing AFAIK.
Might've worked for HDDs, but SSDs have a cap on lifetime writes.
Don't SSDs store information about how often they've been written?
SSD endurance isn't a problem.
I thought all SSDs did that for wear-leveling purposes.
SSD is not for you then, data retention is very poor (single digit years, or few months until read speed degrades in case of Samsung 840 :P). Whats more mere reading degrades flash, current SSDs keep a log of how many times sector has been read, and reallocate that sector when it triggers because read operations upset stored values.
Modern SSDs (last 5 years or so) will wear level by relocating infrequently written blocks.
Reading also wears out nand flash. SSD have read counters next to erase counters, too many reads and drive forces whole sector rewrite to mitigate data degradation.
NAND blocks aren't precious now. Just buy large reliable SSD (may have around 500TBW) and just forget it.
