reduce write access to hard disk

[Jonathan Schmitt <list@detla.de>]

Dear all,
I'm currently trying to build a low power/low noise computer and as a part of 
the concept, I would like to use a flash card as the main storage.
I'm aware, that flash cards have only a limited amount of write cycles before 
the cells wear out and therefore I'm looking for ways to reduce the number of 
write cycles.
First of all, it is obvious, that swap partitions have to be avoided and 
replaced by real ram, so currently I'm planing for 2 maybe even 4 GB of 
memory.
Now, I've once used noflushd on a notebook, which somewhat does, what I want, 
however, with every read cycle also writes are performed.
What I would like to have would be to assign - say .5 to 1 GB memory to store 
all write accesses and only make them permanent every hour or so. So noflushd 
would still perform write access too often. 
Any ideas are welcome :)

Jonathan
