When using RAID5 disk controllers will write large blocks/stripes to disk, so a single 4KB page update can result in the controller actually writing 64KB* to the SSD. This a form of "write amplification" and will increase the speed of SSD failure. Sean * The block size can be even larger, up to 1MB, so the selection of stripe size is very important. For example, Adaptec has a default strip size of 256KB.
