Jerry,

I forgot to explicitly say that the sata controller does have to have
SATA II support.  Alternatively it may say it supports 150 & 300
MB/sec sata bus.

300 is the SATA II speed.  And AIUI SATA II is a marketing phrase.
There is only one spec I think, but the spec allows for 150 MB/sec
transfers and 300 MB/sec transfers.  Early controllers and drives only
supported the 150 MB/sec speed.
