    Any of the benchmarks > 100MB/s are on a sata interface so are misadvertising. Kingspec is a middle-of-the-range PATA SSD. The faster ones use a Indilinx controller + sata-to-pata bridge. See some in the 1.8" ZIF SSD comparison.

    It is my understanding that the limit on the PATA SSD is the 133MB/s transfer speed of the IDE bus, if I am wrong on this someone please correct me but if the PATA SSD has a greater than 133MB/s transfer speed it will be limited by the bus to 133MB/s.

    That's why the use of a SATA to PATA board is useless (bottleneck)
    The only benefit is the bigger storage capacity of the SATA disks

    That is correct if all you are looking for is the speed advantage of the SATA SSD, however here in the US PATA SSDs are getting harder to find and are usually more expensive than the SATA SSDs with comparable capacity.

    That is why i do my shopping directly in China (they are almost all manufactured there) it is way cheaper if you have the time to wait for arrival

    PATA will be limited to 133MB/s and can only do single-queuing. It doesn't have AHCI's NCQ for parallel read/writes.

    The fastest MLC PATA SSDs use an Indilinx controller and sata-to-pata bridge. eg: Renice K3VLAR or Runcore ProIV. The last very fast native PATA drive was a Mtron, but they are now a couple of generations old, don't appear to be in business anymore and miss critical features like TRIM.
