I'm trying to breath some new life into an old Thinkpad X40 by replacing its HDD with a couple of CF cards. I've found a nice adapter will let me install two cards into the notebook's drive bay and plug them into the parallel ATA-3 bus.
The CF big cards are pretty expensive. The big, fast cards are even more expensive. I'd like to get one as fast as possible, but I don't see any point in buying cards that are faster than the IDE bus. Does anyone know what the maximum speed of that bus is? Google isn't helping me here.
