My thoughts exactly.
And 64GB is more than enough for your boot drive if you put all your data on another drive.
If it were not for all the different hardware configurations you could walk up to any PC and pop in your boot drive and go to work.
You can have multiple hardware configurations on windows, that would be extreamly handy for business.
You could check out you boot drive when you come in, pop it any machine you want, do your thing, then check it back in when you leave.
At the end of the day, they just put all the boot drives in the safe.
Take it step further and have no HD's in the PC's, you would just connect to a central secured data server when you booted up, even at home via internet VPN.
Very handy when there is problem too.
Hardware or Software?
Easy to tell, just pop in your backup boot chip and see.
If it still fails, try it on another box.
If it still fails, then add it as a second (not boot) drive to another machine and then fix the software problem, otherwise fix or replace just your box.
Use another box until yours is fixed, and when you get your box back plug it in and go as usual.
This might be handy for homes with multiple PC too.
There is always one "best machine" in the house.
It has the most memory, best video, etc.
You can pop your boot in and use it with no chance of messing up anyone elses boot machine.
Take it with you when you leave and your PC is always in your pocket.
Data transfer speeds are pretty close between sata2 and USB2.
SATA2 is 300MB/s and USB2 is 490MB/s, but it's the seek time factor HD's suffer from.
HD's have to move the disc heads to the starting data segment point and then each subsequent data segment track, then wait for the disc to spin around to that point.
That is why faster spining drives like the 10,000 RPM 72GB Raptor HD I use for boot is about as fast as you get for sata2 boot drives.
That is also why a good defrag and pack (moving all your file segments end to end) util speeds your HD based system up so much, it cuts down on the seek time.
Chip drives have 0 seek time all the time.
Speed is only limited by memory speed and the pipe that connects it to the motherboard.
Even USB speed would be an improvement, but if you could tap even your usually unused PCIe x1 slot that is 500MB/s, an 8x slot is 4GB/s, and a 16x is 8GB/s transfer speed!
We are talking zero seek memory speed on an 8GB pipe.
That my friends is about as close to "Instant on" we'll see this decade, maybe next too.
