Why not use eSATA?

Later UDMA's yes, but the original (first) UDMA was slower than the
47MB/s, which Tim got at the beginning. Practically this proves the
possibility to find a USB/IDE -diskpair, where the USB-disk performs
better than the IDE-one.
Just splitting some hairs...

BTW, is eSATA a one-device-per-channel -bus, or can it be used to hook
n+1 drives via one cable?

Or memory buffering, depending on how much RAM you have. I regularly
wind up in the situation where I make 10 gig of changes in a short
timeframe on the machine with 16G of RAM, and the (say) untar finishes
in 40 seconds, and running 'sync' afterwards takes another 90. :-)
