So, just how long will flash be
around before someone invents some new sexy "standard"? It could be
tomorrow. I've got a perfectly good digital camera tied to the older
PCMCIA form.
Compact Flash has a roadmap of between five and 10 years, but our machines
aren't necessarily tied to CF, because we made the decision to have the PC
Card form factor which allows all sorts of other media ( Microdrives, ATA
Flash, Sony Memory Stick, DataPak etc. ). It's the bus rather than the
card that we are working with. In our major markets such as broadcast, we
are looking to have product ranges with long lifetimes, because our users
demand it. At the minute solid state is still in an interim phase, so we
are keeping the options open as to developments here.
Most of the things using the compact flash assume it went ok and don't
really test or even provide a testing method. They really are not doing
much to the memory, so it probably will do most of the time. I think you
can forget having a recorder that can both play the recording as you
make it from the chip and record at the same time to the chip. The
programmers seem to assume perfect reliability.
This is a good point, and one that I have discussed extensively with our
engineers in Japan. In some ways playing from the flash whilst recording
is not really an issue, depending on where the monitoring is taken from in
the circuit, since it's extremely unlikely that you would have a failure
in the actually write process. If there is a failure, then it is much more
likely to occur in the logic or software, so if you are listening at some
point in this chain ( rather then you would hear any failure. However, I
would very much like to have an effective way of proper confi monitering.
It is possible in software to read and write from the flash
simultaneously, but the main issues are memory overheads in doing this. Be
assured though that we are looking at the possibility of doing this.

It's a lesson in stopping to write the TOC. I make sure the TOC writes
after every track I record. The HHb will remember the TOC through a
battery removal, however, so it's better off.
My old Sony's used Lion batteries, they seem to last forever, they are
all still good, my son is using one of my old recorders as, well, a
walkman. I also had spares, and never pushed my batteries to the end. A
advantage of Lion or NIMH batteries is that you can recharge when they
are partially down.

I figure eventually they may be a way to go. I'm a little worried about
going to any computer item. The manufacturers seem to think we can buy a
new, incompatible model every year. So, just how long will flash be
around before someone invents some new sexy "standard"? It could be
tomorrow. I've got a perfectly good digital camera tied to the older
PCMCIA form. When buying I always try to factor in expected life. With
computer stuff you almost have to figure it's got to give you enough
return in a few months.

I've got a bunch of PCMCIA Type 3 drives I use with my digital camera
and as file transfer to notebooks. I've not had any fail yet and they
are 6-7years old. It's a case of trying to figure what's going to be
around the longest. And playing the lottery is easier and probably safer.

That's one of the flaws in the idea that a couple chips will be enough
for field work. Spares are even more necessary there.
