Sounds like writing to disk always takes an unacceptably long time, so we should stop writing to disk and do something else.

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.
