Installation was pretty straightforward, I only had to cut/saw the plastic bit off one side of the adapter’s IDE connector to fit. I also had to shorten the master/slave jumper so it doesn’t poke the PCB and battery, use a slimmer jumper bridge, and electrical tape on the backside (see red dots in the photos).
Speed with a 300x Lexar CF is blazing, bootup is almost instantly. Too bad there’s no affordable 300x 32GB card available, so I have to see which 16 or 32Gb card is fast enough to be useful in the X5. I’m leaning towards a Kingston Elite Pro 133x (should be faster than 133x in reality), or a Hama HighSpeed Pro (should have similar speeds as the twice as expensive SanDisk Extreme III). On another note, the X5 is now also quite a bit lighter than with the 1.8″ HDD inside.
