UPDATE: I just ordered a MyDigitalSSD High Speed 32GB ExpressCard/34 SSD Solid State Disk from Amazon. It does use the PCI Express interface instead of USB. First, I will install the piano software then install the samples on this card.

Even if it doesn't work, I can always use it for extra storage or it might work for the PTP project storage. After I experiment, I will post how it worked for the piano.
