... which is still much higher than you would get from a blu-ray 120mm
disc. So the point is that 120mm Blu-ray is not a good substitute for the
HDD in the new generation portable HDD recorders.

...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.

.. unless the recorder is a 96k 24 bit uncompressed LPCM recorder - the
memory cards would cost nearly as much as the recorder!
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
