I actually bought one of those and installed it in a laptop I previously had (was stolen). Worked nicely and quiet

, which was my main purpose. Linux didn't have any trouble installing on it, and I didn't notice any speed difference. The card was a "slow" 50x version so going with something faster would boost that. Of course for our application speed isn't a big deal for storage.
Looks like the guy I bought it from is not selling them anymore. I managed one for 10 dollars shipped from Hong Kong off of ebay from user mobilesupply. That was the one cf version though, not for two different disks.
