SSD writes are slow because the technology requires to write (erase)
in large chunks of 256k or more but the OS writes in chunks of
4K..64K. Such small writes therefore cause extra read-modify-write
cycles.

The better SSD therefore have some huge write cache so that at least
large sequential writes get faster.
