One must consult the documentation of that device. This wear leveling is low level and most devices do not export any information about it. Recent SSDs start to export some values through SMART that let you monitor the state. Some companies think that hiding is better than exposing... Jan

Hi, It's important to note that disk-replacement type SSDs perform much better with very small block operations, generally 512 bytes. So the lower your file system block size, the better -- this will be the single most significant performance tweak one should do. This is true for the bench
