A few other companies have announced solid state drives with a USB 3.0 interface, but we have yet to see them made available. We know that distributers will be receiving their first shipment of A-DATA N002 products any time now. That means that by the time you read this major etailers should have the products listed, but I think the cost will keep them from selling, unlike the A-DATA S599 SandForce controlled drive that comes in at 380 USD for the 100GB capacity.
When it comes to performance, we have yet to see USB 3.0 live up to expectations or even the claims of 10x performance. Right now we are seeing around 5 to 6x the speed of USB 2.0, but I have a feeling things will change once Intel hits the market later this year with their USB 3.0 chip and next year when Intel has a USB 3.0 solution built into the south bridge. NCQ in USB 3.0 will take a while longer and I am surprised that the USB-IF consortium didn't address this issue from the start.
Either way it goes, USB 3.0 is faster than USB 2.0 by a significant margin and we all have been counting the days for USB 3.0 products to hit the market since transferring anything of significant size over USB 2.0 takes so damn long. The A-DATA N002 makes great progress to the kinds of products we all want to see at the high end and as such we really can't complain about the cost. This is a premium product and one that shows great engineering, determination and innovation from A-DATA.
Other companies with much larger marketing budgets have been showing off USB 3.0 SSDs, but the reality is that only A-DATA has gotten them out into reviewers hands and has confirmed shipping products to distributers at this time. This coupled with A-DATA's successful launch of a SandForce SF-1200 before all but one other manufacturer means that A-DATA is starting to become a larger player in the SSD market.
