Supertalent has annonced the release of 2,5" SSD discs equipped with a PATA interface. These discs will have rather average performances, 80 MB/s in reading and 40 MB/s in writing and will range in capacities from 16 to 128 GB.
However, if their price is kept low, they could find their place in older Macs (the Cube?) which would give them a whiplash in performance and silence. One could even consider in installing one in an Apple TV so that it ceases playing the role of a radiator during the summer.
