The reason for this is because swap does a lot a small read/writes on the disk, and (because this process was never optimized for SSD) uses the same sectors a lot. This is not a problem for ordinary HD's, but in the case of SSD's, this would mean certain memory cells would wear out faster, effectively shortening the life span of the SSD a great deal. More recent SSD's firmwares contain specific algorythms that try to write to all the cells of the SSD an equal amount of times, while also trying to avoid certain cells getting written more to than others.

In any case swap is not necessary when you have enough RAM, and certainly not when the OS is on an SSD since that's a multitude times faster in terms of speed (and certainly in terms of access times) than an old school hard disk.


Yes.
