I've been tempted to use a solid state drive for the primary disk for my desktop. Of course I only need to look at the current prices in order to come to my senses. Sure, you could pick up a CompactFlash to IDE converter for next to nothing, but a decent sized CF card will still set you back a nice chunk. But what if you could combine two such cards to create one drive?
That's the idea behind the DIY SSD. Just pop in two CompactFlash cards, hook it up and you're good to go. In order to get the most out of your drive, you'll want to buy the fastest CF cards possible. While you might not be able to afford the largest cards, you can always upgrade them in the future.
The two downsides I see here are the price, and connection. First, a $200 adapter is going to keep things pretty pricey. What's strange is that while it is a SATA drive, it only supports 1.0. You'd think they would at least spring for SATA 2.0 compatibility.
