It's actually quite amusing how modern OSes can abstract, speed up and hide away those things that are still slow even on nowadays hardware.

As far I remember NAND/NOR memory (used for SSD) is very slow to *erase*. The erase operation can be performed only by big chunks, requires higher voltage etc.

SSD vendors circumvent this by adding several layers of write buffers to achieve good test results.
