I've been thinking about this and have some thoughts...
- Density. In having a camera that's based on SmartMedia, I've been
for larger parts and I can't find anything on the market larger than
CompactFlash is generally available up to 128meg, and it looks like
Electrix found 256meg parts.
- Durability. While I love the small size of SmartMedia, my impression is
that it is a medium which was designed for thin applications such as
digital cameras. Short of storing it in an external plastic shell, it is
not exactly resilient to bending. I cringe every time that I move the
from the camera to my USB reader.
- Cost. CompactFlash seems to be slightly less expensive on the street
(about $20 less for commonly available 64meg parts). This isn't a
significant difference to the consumer, but the *value* is greater when
add in the durability question.
I don't think that the part speed will be much of an issue. I would think
that the Repeater will *not* try to play _directly_ from the media, but it
will instead buffer the data stream first. This solution would be much
cost effective in the terms of being able to use slower/less expensive
media, and allows for various data manipulation tricks along the way.
Given the price of RAM these days, I would suspect that there is a healthy
buffer available in the machine for stream buffering as well as scratch
area for time/pitch shift magic.
If this is all correct guessing, then I personally would option for the
larger and more durable media at a lower cost, CompactFlash.
If we figure that the machine is *not* using any compression, and that it
is sampling/storing data at 44.1khz, 16 bit, then we're looking at the
general numbers of 5meg/minute for a mono track. Given a 256meg part, that
would give us about 50 track minutes. Obviously, even simple data
compression would double that.
100 track minutes on a looper box? And the ability to slam in another 100
minutes on a dark stage without worrying about breaking the media if you
insert it off-center?
