I am glad you said flash ram is slower than hard disk.
I've been saying this for years, trying to help people realize that flash ram has a specific purpose, and speeding up operations compared to a hard disk, just isn't one of them.
Now flash ram will be getting faster in the next few years, and if it surpasses hdd speeds, then an update to this information is due.
but for now...PEOPLE FLASH RAM IS SLOW, on top of that it has a more limited life...anyone buying these flash solutions for boot speed....just stop it. ok seeks are electronic, you'll find a slight speed increase on seek times, but certainly not on sequential reads.
