Any of those drives should work. Serial ATA150 and SATA I are the same thing as are SATA 3.0Gb/s and SATA II. The Western Digital SATA drives that come with the S3 Tivo have a jumper that limits the transfer rate to 1.5Gb/s or SATA I mode. Removing the jumper or getting a SATA II drive won't have any effect on the operation of the Tivo.
