Right. I'm new to 2.5" drives. The connector SD uses in the 744 is
shorter than the 2.5" drive's (at least the sone they supply) and
requires that two of the pins on the drive be bent back for the
connector slide fully on. I need to do some research on this; I'd
hate to blow the warranty on a new drive installing it into a 722/744.
If I went on a long trip, I'd take along another 80GB drive to swap
out about half way and not mess with transfers at all until I got
back home.

I should ask SD if the Mic/Line inputs have the same A->D, I assume
they do. The difference in clarity below 400Hz is glaring, even shows
in the wave form to my eye.

I've been experimenting with two warm omni's in the "rear" (mbho
603/100D) in part to make sure I get plenty of low-mid data for
capturing local reverberations. (These mics, also are very immune to
walking vibrations). I would, however, prefer to process the signals
from these mics with a 744 style pre (If I could) because it adds
less "grunge" in this Hz range. Terese, my wife, noticed the improved
clarity when walking through my studio with my very first tests. I
should conduct a Peet test comparing the 744T's A->D to my RME's. I
think you'll find the MKh30/60 combo will have less grunge thru the
722 pre.

Maybe the above mentioned 2.5" drive swap is best and you could use
the CF for dual record BU all the time. When you get home one can
mount the 2.5" drive on a mac or PC's internal drive harness with a
$12 adapter. The 2.5" drive even works in a external 3.5" FW case
with the $12 adapter.
Recording to a drive is fantastic. I can spend the time I once spent
listening to transfers in real time making "select outs" and do
things like drop markers
SD's planned FW code will allow simultaneous record to a "pocket"
2.5" external drive using the power from the 744. That has some neat
applications when you think about it. No transfer is necessary with
this, really. You could mail a CF to someone who needed 2GB of files
in a hurry and still be BU'd on the road with no laptop.
The advantages of fully-compatible drive tech for recording/uploading
are pretty significant. Makes me more aware of the proprieties of the
MD formats. Rob D.
