I've got an extra sitting on my desk, and it's either ebay or try it in a laptop.
It's too small to run in the HTPC, old gaming machine, and, to be honest, I didn't notice a big difference between it and the Velociraptor when I had it installed in the Athlon 3000.
I've got Kingspec drives that show 70 MB/s Pata, and good access time in a used CF-51, so, I figured if I double the through put, I might actually notice the difference.
Would probably have to be an XP Pro laptop, since I suspect 7 would eat the speed difference.
