ECS Also Providing USB 3.0 and SATA 6Gb/s Cards
ECS is also releasing two PCI-Express cards for USB 3.0 and SATA 6 Gb/s.
It looks as if a good handful of manufacturers is ignoring Intel's hesitancy and is jumping on the USB 3.0 / SATA 6 Gb/s bandwagon. ECS is the latest to produce new hardware, sporting two tasty PCI-Express expansion cards: one providing USB SuperSpeed and one providing the new SATA. These PCI-E cards provide access to the new technology without the need for replacing the entire motherboard.
The news originally appeared on XFastest, however TechPowerUp translated the post, reporting that the cards use the NEC µPD720200 controller for the USB 3.0 version and the Marvell 88SE9123-NAA2 controller for the SATA 6 Gb/s version. According to the post, the USB 3.0 card provides both ports on the rear-panel; the SATA 6 Gb/s card provides one internal SATA port, and one eSATA 6 Gb/s connection.
Currently ECS has not released pricing or ship dates for either version, but we're expecting them to hit the market during Asus's and ASRock's launch window of similar products. There may be a drawback to using these cards however: both supposedly remain in 1x PCI-E format. If that is indeed the case (for who knows why in a 16x world), the narrow pipeline may limit the overall Mb/s speed.

Of course, neither of these will really be cost efficient until they are integrated on motherboards.
True, integration would be nice...
Also would be kind of cool if we just ditched SATA and eSATA altogether and used USB 3.0 only for all. I already have dozens of cables around my place, I don't need any more (plus SATA cables are too stiff for proper cable management).
I'd think one with two USB, 1 eSATA and two SATA would likely be the best on a 8x lane.
Now, how about PCIe 3.0?
And also how about GPUs recognizing what revision (PCIe 1.0, 2.0, 3.0 etc.) you have so it can detect how many external cables you need (PCIe 3.0 allowing all modern GPUs with any external cables).
As for PCIe 1x - its 250mb/s both way, the USB3 card will be fine (atleast quicker then ~44mb/s USB2) but SATA3 on PCIe 1x is useless when an onboard SATA2 controller can push ~270mb/s - beyond PCIE 1x
Overall, Im happy as I can start planning for a true future proof build.......
I'd rather see this on the motherboard early next year than in add-on cards.. because motherboard designers really suck at making pci-e slots far enough apart so that they don't overlap with a video card. Generally on most boards, you lose a 1x pci-e slot during this tradeoff especially if you sli-crossfire config. When properly config'd a mb/ should have 2 x16 slots back-to-back (but far enough apart for cooling which means dont make them fatter than a 3.5" hard drive, dummies-- make cooler running chips!), an X1 or X4 slot, then 1 or 2(if there's room left) for legacy pci 2.X (without costing mega bucks $$)
** Then again, why not just make 2 x16 slots for video, and an x8 slot which can also pair down to 2 or 3 legacy pci slots with an adapter (yeah, how would that look? well, the x8 slot would utilize the next breakout on the case for wiring, obviously) 2010 is the year of new mobo sockets anyway.. might as well toss legacy pci as well.
Thats because of the flash side not the USB side (for most anyhow)
