Check out this PCI adapter that lets you use up to 4 CF cards as a SSD (via John).
Of course I have a bunch of more questions-
Can this support the newer huge CF cards? 64GB ones are supposed to exist although the largest on NewEgg is 32GB. But the 32GB one only costs $134, so a 128GB SSD for $600 would be awesome. The pictures only show the 2GB and 4GB cards so?
There are versions of this that work with notebook sized IDE and SATA adapters. I bought one of the IDE ones before I realized that the app I have in mind I really should have gotten the SATA one.
Is there going to be a PCI-Express version soon?
What does the performance look like? For boot? Does it help Windows runtime performance much? Would you want to use it as Swap? What about for running a database?
I wonder if this thing would be interesting for data-center machines. If you could have great performance and higher reliability than a hard-drive, this would be really attractive for servers. For your typical web-server 128GB is more than enough…
