Subject: Re: [LIB] solid state disk

I looked at using PCMCIA flash drives as in place of removable hard disks
as removable media some time back. I was using SyQuest 88Mb SCSI drives,
which are no longer produced and it was hard to find internally mountable
removable SCSI devices. Size wasn't a big issue, as it was for a system
running OS-9 (a real time system, not to be confused with MacOS 9) which
needs about 20Mb for a full development system...

I think the show stopper for the flash option was the limited number
of rewrites that each block could take. I think it was in the hundreds, or
at best thousands, which might be OK for a seldom modified root partition,
but not so good for inodes and super blocks, or worse still systems which
use bitmap sectors for managing free space... 

Anyone know that the specs are like on this for current devices, and
how it compares, say, to re-writeable CD media?
