    40GB ATA-6 and:
    5400RPM with 8MB cache -or- 7200RPM with 2MB cache?

    no brainer. 7200rpm

    Indeed. The integrated cache on a hard drive has virtually no effect on real life performance while RPM translates almost directly to speed (seek times). 7200 RPM is about ~30% faster.

    I was asked if a 10K rpm 2.5" drive was available - never seen one. Unless anyone knows better?

    10K (and even 15K) RPM 2.5" SAS hard drives are pretty common :)

    I suppose you are interested in SATA? I don't think there are any such things out there. The heat output and power consumption would make the things unusable in a laptop.

    Thanks to all. 10K would be nice but $---.

    Be careful eventhough the drive is running at 7200RPM you'll use more battery life to power that drive. The 5400RPMs with the 8MB buffer will make it feel like a 7200RPM which would use less battery. You won't even noice the speed difference if any.
