New 'SATA Express' spec supports speeds up to 16Gb/s

The Serial ATA International Organization (SATA-IO) has announced the development (PDF) of a new standard that combines SATA software infrastructure with the PCI Express interface. Colloquially dubbed "SATA Express," the new technology…

Sata 3 @ 6Gb/s is enough for me.
lol that's great that is good enough for you, but you're just one man.

Its not fast enough for the industry and these are the people that bring in the money not end users!

I wouldn't get this even if i could buy it like Lion said, there's a big gap between devices and ports :p

Techspot Quote above:
"The amalgamation will offer an affordable way to provide devices with interface speeds of 8Gb/s and 16Gb/s (one lane via PCIe 2.0 or two via PCIe 3.0)"
------
I'm having trouble understanding this statement. If PCIe 3.0 effectively doubles the transfer rates of PCIe 2.0, then adding an extra lane with PCIe 3.0 should quadruple the rate of PCIe 2.0 with one lane.

Studying the PCIe pin-out, each lane has its own set of pins. Maybe this is why there is two SATA ports, one SATA port per PCIe lane. This would give 8Gb/s with PCIe 2.0 and 16GB/s with PCIe 3.0, while using both PCIe lanes.

Please tell me if I'm going in the wrong direction. I've spent a few hours trying to understand the comment above.

Sweet another standard we all have to upgrade to now...
Here's a tip: if you weren't planning on dumping several thousand dollars into PCIE-based SSD storage, you can safely ignore this. Most drives can't saturate the 3Gb/s SATA link, let alone 6Gb/s or 16Gb/s.

The devices that use these ports really have some catching up to do. The computer world is beginning to resemble Black Widow breeding habits. The convex or "male" is improving at a drastically slower rate than the concave or "female".

"speeds of 8Gb/s and 16Gb/s (one lane via PCIe 2.0 or two via PCIe 3.0)"

How is 1 lane PCIe 2.0 only half the transfer rate of 2 lanes PCIe 3.0?

The problem here is that SATA 3 is being completely saturated already so, what we really need is SATA 4 to keep up. It's the slowest link in the chain at this point. Especially in a couple months after PCI Express 3.0 capable motherboards, CPU's & GPU's are out.

I dont know about you all but i dont plan on giving up my beautiful, precious PCI's up... they are reserved for my loving graphics cards and workstation cards <3 <3 <3 If i want that kind of speed ill get a SSD PCIe 4x drives and keep my storage drive as a HDD...

:D
