Same as SATA? Not a chance. Not until USB starts adding DMA instead of doing everything the slow way by dumping everything on the CPU via interrupts.Most modern drives should be faster on usb 3 just because data can be sent full duplex instead of the half as it was in usb 2. Performance should basically be the same as if it was a sata connection.
Honestly, I don't see what the big deal is. The only thing that this will affect is portable hard drives. Let's face it, even USB v1.0 is perfect for devices like mice, keyboards, webcams, Internet dongles, Bluetooth dongles and even magicjacks. 99.9% of the time there will be no difference between one and the other unless you drop a PANTLOAD of money on a USB v3.0 hard drive. The eSATA ones are expensive as it is, wait and see what the USB v3.0 drives will cost. I wouldn't have it as a criterion for purchasing a motherboard. If I want USB v3.0 later, I'll add a card. It's just not worth it right now.
I have a Zotac H55ITX-A-E motherboard. It has a mini-PCIe slot which conforms to the PCI-SIG's PCIe Base Specification 2.1. I purchased a mini-PCIe USB 3.0 card:
http://www.commell.com.tw/Product/Peripheral/PCI Express mini card/MPX-7202.HTM
and am using it on this motherboard. My case is a LianLi PC-Q08 which has two front USB 3.0 ports. When in Windows, the ports work as they should. However, when I go to the boot selection screen after POST, none of my bootable USB flash drives appear when connected to either of the USB 3.0 ports.
They do appear when connected to any of the USB 2.0 ports on the motherboard though.
Does USB 3.0 not support booting from USB flash drives? I have checked my BIOS and have set it to be able to boot from USB flash drives.
Also, when any USB flash drive is connected to any of the USB 2.0 ports on the motherboard, they're listed as hard drives in the BIOS, but when connected to either of the USB 3.0 ports, they're not listed at all.
Anyone know why this is happening?
Also, Windows 7 Ultimate x64 didn't have USB 3.0 drivers built in. Anyone know where I can download the latest USB 3.0 drivers? The card I have uses a NEC D720200F1 USB 3.0 chip.
How about fall this year? In the Q3 Intel product matrix thier SmackOver2 board (X58SO2) is described as having twelve USB3.0 ports (six rear and six by three internal headers) and ten SATA 6Gb/s (+eSATA speed not stated).Intel won't be doing a USB3 chipset until next summer, at earliest. Is every non-intel controller garbage and every driver not provided by intel crapware?
Is it confirmed that those USB ports are actually native to the southbridge and not using a 3rd party controller?First post yay!

Looks like a new southbridge while retaining the X58 name.
No but the spec does not mention any USB2.0 ports and I am not aware of a third party controller that has that many ports.Is it confirmed that those USB ports are actually native to the southbridge and not using a 3rd party controller?
SATA is limited to 300MB per port, not overall. You can get 500MB/sec with drives in raid using SATA2 controllers, ideally the ICH10 which is by far the best on board controller.I have an OCZ Vertex 2 that writes as fast as it reads, pretty much, at around 250MB/s.That's pushing the SATA II limit. I'd like to get another one, since they are excellent drives, and run them in RAID 0. But the only benifit I'd get right now, using SATAII would be +50MB/s transfer and more single drive space. IOPs would go up too, but would still hit the SATAII wall. I can run SATA III on my new MB too. I'm just wondering is the tech is mature enough to do two SSDs in RAID 0. 500 MB/s transfer speeds would be finally getting at some serious speed, but at 30GBs a minute, that's really not that fast considering program and file sizes now--for the user that does CAD, Photography, etc. But then again, 30GB a minutes would transfer two OCZ V2 60GB drives in two minutes--lol.
Actually aft3er I thought about it from writing this, I'm really not too worried about it until SSDs come down in price and offer at least 500Gbs of space.
There are a few types of RAM drive. Some are on the PCIe bus and have backup power to keep the data intact. Others are a virtual drive created in system RAM. The latter is ideal if you need a scratch drive for Photoshop, 3DS and such.But, don't you have to install every time? Explain this please. Thnx.

There is the option of having some app copy certain data into a RAM drive made in system RAM every time you start the system. That'd have an initial bit of lag, but after that would be super fast. When the system is powered down the contents of the RAM drive would then be stored on a HDD or SSD.OK. I thought I heard of fellows installing there game on the
system ram. So they were talking about PCIe ram?
Well there is "light peak", information on it is sketchy but it looks like it will turn out to be primerally used for docking apple laptops (and maybe other brands too later).I wonder why fiber-optic inter-connects aren't being developed....or are they???
