.. unless the recorder is a 96k 24 bit uncompressed LPCM recorder - the
memory cards would cost nearly as much as the recorder!
What is worth considering here, that even with a 4GB compact flash costing=
=A31500 ( which will drop very fast over the next six months to a year ) -=
this is a one off purchase, and not the archival media. How many DAT tapes=
does a professional recordist use during the lifetime of a DAT machine ?
Even with MD what is the total cost of media over the lifetime of the
product ? The Marantz PMD670 ( which is coming in at significantly less
than =A31000 without media, so the media would be about twice the cost of
the machine itself ), plus one of these 4GB cards would give you pretty
much a full working day ( six hours or so ) of uncompressed stereo
recording time. If you record every day in a professional context then
even with the media at this price it still works out a lot cheaper over
product lifetime than DAT or MD according to my calculations.
If you don't want to carry a laptop in the field, there are now also
available options for dumping the contents of a card onto a larger
portable hard drive
for example the KingByte X drive ( http://www.kingbyte.com ).

...but in combination with shock buffering, 2.5" HDD's work very well in
bumpy situations. The 'write' speed of an HDD is the key to extremely
effective shock control management.

Admittedly, I do agree that solid state is the most reliable form of
storage
for mobile, low storage capacity applications especially those using
compressed audio formats. Roll on the day we can buy 30GB flash memory
cards
costing around $100. 8GB will be available about 2006 and at a pretty
scary
price! so it could be some time.
all the best
