To the speed of the built-in Microdrive:
I've just compared the speed of the built-in Microdrive to an external CF-card (Sandisk Ultra II 512 MB).
Write-test:
TESTDD=/mnt/cf/test-dd
date; dd if=/dev/zero/ of=$TESTDD bs=1M count=256; date
TESTDD=/hdd3/test-dd
date; dd if=/dev/zero/ of=$TESTDD bs=1M count=256; date
Read-test:
TESTDD=/mnt/cf/test-dd
date; cp $TESTDD /dev/null; date
TESTDD=/hdd3/test-dd
date; cp $TESTDD /dev/null; date
The results (read - write):
Microdrive (2.080 kB/s - 1.986 kB/s)
CF Sandisk Ultra II (2.221 kB/s - 2.730 kB/s)
Of course, this test doesn't meassure the random-access-speed!
Nice infos about CF-card speed can be found at

It would be very interesting how fast the internal RAM-disk of the other models is, e. g. C860, C1000!
Did anyone change the C3000-Microdrive into a CF-card? Does that show speed improvements?
