Multitrack recording on SDHC card in MacBook Pro SD-slot

[Tony Scharf]

Most of the current crop of cheap multi-track recorders manage to do
it, so I cant see why your macbook couldnt (Though OS overhead may
come into play here).  It would be worth a shot, anyway.

But I have to ask:  Why not just record to the hard drive and then
move the project to the SDHC card later?  I do that with my netbook
with good results (never tried recording direct to SDHC).

>>> From Wikipedia: sustained write speed for a class 2 SDHC card (the slowest available) is 2MB/s so you should be fine even with 100% overhead for protocol.  I'm sure someone will be quick to point out if my maths are off (which they might well be).
