hayDave!..........how they hangin!
The sky and your pockets is your limits..........to tailor your PC for a fast OS (Operating system C:) drive remember all you really need is enough room for the operating system and maybe a few programs........everything else from program through to photo storage can be put on slower drives
The OS takes up about 55Gb.....a few programs ....maybe 15 to 20gb...........so 80 to 100Gb of fast drive space
can be a workable minimum
This way you can spend a little or a lot depending on what sort of speed you need or want........need and want are very different!
Do you need or just want 7 to 800 mb/s read and write speeds ?
