Performance isn't always important. Suppose you need to bood a device who's internal disk needs reformatting and the system has no floppy or CD? Think of embedded systems. Additionally, embedded systems with compressed on disk data of less than 2MB are entirely useful. That would take 2 seconds by your estimate. There's nothing wrong with 2 seconds.Joshua Myer wrote on Thu, Nov 07, 2002 at 01:03:45PM -0500 :Is it possible to boot from USB storage?This is dependent on your BIOS, not on your OS. IIRC, Linux had some support for a USB storage root fs, but i don't know what the current state is.The only state I forsee is _slow_. A flat out balls to the wall copy from a local filesystem to a usb filesystem across a USB 1.1 bus proceeds at a rate of about 1 MB per minute. I just see that being horrifically slow, especially when people are used to ATA100 or ATA133 speeds. Hell, a plain old fashioned IDE controller runs faster than that. Now USB 2.0 will be interesting if it can sustain the throughput that it's rated at. Blue skies... Todd
BTW: That's a LOT faster than a floppy.
Not everything is a full desktop machine and performance of a system isn't always measured in MB/sec.
Cheers!
