USB 3.0 and SATA 6G Performance Preview - ASUS brings the goods
ASUS brings the goods
Earlier in the week we took a look at our first bit of hardware for the upcoming SATA 6G standard: the Seagate Barracuda XT hard drive and the ASUS P7P55D Premium motherboard with the integrated Marvell 9123 SATA 6G controller.
It is obvious upon reading that article that while we were more than a bit let down by the performance changes from standard SATA 3.0 Gb/s the fact that ASUS has a solution available today that will provide an upgrade path for SATA 6G hardware down the road is good.
Probably more exciting than SATA 6G is the upcoming adoption of the new USB 3.0 specification that will greatly reduce a bottleneck in external storage that exists today on almost all PCs. USB 2.0 is limited to 480 Mbps (or 60 MB/s) and in reality very few components were ever able to go much faster than 40 MB/s on a good day. The new USB 3.0 standard runs at 4.8 Gbps (or 600 MB/s) - this is obviously a HUGE jump in performance and has the potential to make external storage a more reasonable high speed solution. Backing up a 2TB hard drive over current USB 2.0 would take about 10 hours or so; with USB 3.0 that could move to as little as an hour.
The ASUS P7P55D-E Premium - USB 3.0 and SATA 6G in one package
This week we heard our first rumblings of the new ASUS P7P55D-E Premium motherboard that would offer both of these new storage technologies on-board.
The ASUS U3S6 Add-in card - USB 3.0 and SATA 6G for everyone else
Along with this new motherboard ASUS also sent us an add-in card that will offer both USB 3.0 and SATA 6G connectivity to all other users that didn't have the good fortune to have them integrated on their current motherboard. The ASUS U3S6 (get it, USB 3.0 and SATA 6G?) card will be sold individually with a modest MSRP of $29.
USB 3.0 Hardware Arrives
While we have already gone over our first SATA 6G hardware, we obviously needed some USB 3.0 accessories in order to put this new technology to the test as well. Along comes an engineering sample of an ASUS USB 3.0 hard drive docking station.
