Inside the drive itself, it *may* be using UDMA/133 to transfer data
between the PATA circuitry and the SATA bridge chip (inside the drive).
Not all drives are built that way (in which case the drive is merely
trying to keep people like you happy by reporting these obsolete fields)
but many SATA drives are.
Outside the drive, over the SATA cable, it is SATA150 just like
every other SATA1 drive.
