I have been reading an old thread about digital chart storage on
remote usb drives.

A lot of speculation about power consumption and particularly
hardiness.

If you purchase a hard drive based Mp3 player such as an iPod or
creative system you get it all done for you. The software can be setup
to recognise the attached unit as disk storage in the same way that a
traditional drive can, the power consumption has been engineered to a
minimum, they are significantly 'hardened' against rough treatment
and .....
you get a music store for all those bulky cd's as well.

Our ipod has 40 gig of storage and currently about 5000 song
recordings on it. Theres still 2/3 free on the disk!
