Operating Systems in Memory (I Wonder...)

[Haarsma, Michael (SAPOL)]

Exactly Kym, you are restricted to SATA speeds 'only 150MB/s' but you
get the crazy seek times of RAM + PCI bus latencies. By RAM speeds I
meant latency because during boot there isn't much sustained read/write
so the 150MB/s wouldn't help as much as the ~8ns access times :)

Could be a handy option to look into David, that doesn't involve bizarre
scripts and additional complexity. As you leave your machine on all the
time, you wont have too many issues with it loosing its data. Check out
some reviews and see if you think it will suit your needs.

Cheers,

Michael
