[ale] Microcenter Free USB sticks

[Greg Freemyer]

Define slow.

I use usb a lot in both linux and windows.  Similar performance in both.

1GB/min best case, uses rotating disk typically.

Cheap thumb drives, way slower.

These cheap thumb drives seem to require a erase cycle for every erase
block update.  It makes them painfully slow.  Ie. A erase cycle takes
longer than a head seek with rotating drives, so they are slower than
a disk randomly seeking around the platter(s).

I haven't tried to optimize the partition layout.  I've just assumed
the thumb drive manufacturer does that.  If not, repartitioning with
the partition starting on a erase block boundary should help.
