SATA 300 drive performs exactly the same as SATA 150?
I recently purchased a SATA 300 WD drive from Dell as an addition to my SATA 150 drive that is already in my system, and after running HD Tach, the test results show both drives running at the exact same performance level, and not at the SATA 300 level either. What's the deal? Did I get scammed by believing the SATA 300 will be faster? I used a 300mb data transfer compatible (supposedly) cable and all that I bought from satacables.com. Any ideas? The burst rate for both drives is 196mbps.

SATA300 is just another performance solution in search of a problem that does not exist.

However, in reality as the actual hard disk is the same . SATA / IDE / SATA2 are the interface technology names. The interface only handles the data from the disc to the motherboard. The slowest thing is the HDD its a mechanical thing the best go at maybe 70mbyte/sec ie 560mbits/sec all well within ATA100 ( 100mbytes/sec) let alone ata133 or SATA150 . Its a bit like having a huge water tank feeding a long thin pipe to your tap you get a trickle ( like Big disk/big cache on USB1) and the mains feed on a 22mm pipe keeps up easily. The other extreme is having a pipe 20foot in diameter to an equally big tap when the tank empties in milliseconds and you have to wait for the tank to fill from the mains via a 22mm pipe ( SATAxx) . In both cases the water main feeds at the same basic rate no matter what

Check out http://www.seagate.com/support/disc/sata/st3160812as.html
for info on setting autonegotiation speed faster. Also, there's lots of
useful info & links under Wikipedia w/SATA entry.
