This is a plain old Western Digital 320gb hard drive with VeloSSD caching software applied. This is really impressive.
I would like to see other benchmarks from some 3.5 hard drives. I don't care if they are 5400RPM or 7200RPM, I want to see a before and after.
My 32-bit Windows 8.1 supports only 3.2GB RAM out of a single stick 4GB Samsung 20nm module. I had to install 32-bit instead of 64-bit as there were only two 512MB DDR 2 modules at the moment.
