hm... i'd trust solid state drives for alot of things, still mainly
routers and in thin clients though tbh... and that's because the read
process doesn't affect it
(apologies if there's a stack of grammatical faults with that sentence!)
Russ, Andy yes, you are absolutely correct. I wrote it incorrectly as
read write processes. It is write processes that 'wear out' solid
state drives. Pure read processes don't do any harm, or so I believe.
What I want to do is have the server boot from a CF card in RO mode.
The second drive is to be a hard drive (as in standard platter type)
and that shouldn't have all that much sue in write states. However,
with a standard moving platter(s) hard drive even read states have a
wear effect because of the mechanical movement of the read write
heads. This should be lessened to a normal hard drive in a PC though
because it will contain large contiguous files that once in place are
not overwritten.
