There is something called read-disturb, where reading a row of NAND over and over again can disturb adjacent rows. The effect is many orders of magnitude lower than the erase wear effect and data caching within the drive (as well as data caching in the OS) mitigates it significantly. So for all intents and purposes you don't have to worry about it.

The SSD's normal internal scans will detect the bits when they start to get flaky and rewrite the block then. It might do some rough tracking to trigger a scan sooner than it would otherwrise, but it is more a firmware issue and not so much a wearout issue.

Does this mean that SSDs will lose data if you reach the write limit and continue reading from it?
