I think it was Dave that was recommending the solid state disks.
When moving over to solid state, keep in mind that the consumer CF/SD
cards are not designed for environments where there are a lot of small
writes. The technology is improving rapidly as well, so the market is now
swimming in flash of varying degrees of durability with no clear
identification.
There are wear levelling algorithms built into the cards to help extend
the lifetime of the flash, but you'd be surprised how many writes there
are when using conventional filesystems! For instance, every time you
access a file, the atime (last access time) gets updated unless you
disable it.
Another caveate is that the cell size is (I believe) 32kb, and requires a
full erase/write cycle to update any byte in that cell. You unfortunately
can not control this, as the memory storage mechanism is abstracted away
in the hardware and presented to you as a block device unless you are
using an MTD (you're likely not if ATA/IDE/USB adapters are involved).
This will all be moot in a year or so though, the newer solid state disks
support a stupid number of writes.

Hi all, thanks to a tip from Simon I'm looking at replacing HD with
Solid state drive SDHD in IBM thinkcentre PCs I would have to replace
the IDE drive for a new drive anyway, so the cost for the adaptor and
memory card (say 8/16 Mb) must be in the region of $85
My question is can I what combo would work well as there are many
adaptors (at Dealextreem) and lots of memory types.
