USB 2.0 bulk transfer rate is about 40MBps and ATA/133
on a 7,200 rpm drive has a sustained transfer rate that can be
twice that. Furthermore, installing a Windows OS in flash
memory and getting it to boot is still a trick - one that you
probably can't do. Just put it on a hard drive and be happy.

One very fundamental problem with this approach
is that most flash drives cant do that many writes.

Why does the speed matter to you ? >> Stay informed about: is a usb 2 flash drive faster than any IDE drive? |

Unless you use a IDE flash disk built for speed, you get much lower
trannfer rates and only somewhat better access times. USB flash
is pretty slow. Fast IDE flash is _very_ expensive.

Pity then that's not how the OS is accessing it.
Random access on a HD is about 1/10th the sustained transfer rate.

Tell us "Folkert", how does one measure the average
percentage of time that a HD is doing "random access"
as opposed to doing sustained transfer?
