The guys over at PC Perspective have done some initial tests with the Seagate 2TB SATA 6G 6.0 Gb/s XT drive, and the results leave the consumer market wanting. Showing little to no performance gain over the older 3GB/s interface, the results are far from stellar.
“So…what can we say here? In reality, the performance benefits of SATA 6G technology are basically completely unrealized in our current testing. We have no idea what really to expect in future iterations of SATA 6G hard drives, but if the Seagate XT is any indication, the performance benefits for standard spindle-based hard drives will be pretty low.” – PC Perspective test crew
However, one needs to take into account that:
a) The new interface is aimed at SSD drives which are pushing the limit of the current SATA 3Gb/s interface at the moment.
b) The test sample was an early pre production unit, which should improve before retail.
With SSD drives demanding a price premium for relatively small storage capacities, the SATA 6G 6.0 Gb/s interface is likely to remain a wasted feature for some time to come.
