Serial ATA International Organization wants 1GB/s per PCIe lane
The Serial ATA International Organization (SATA-IO) announces it has started the ratification process for SATA Express, a new storage standard that uses the PCI Express interface for client storage. The new standard is expected to be completed in 2013 and will enable transfer speeds of up to 1GB/s per lane.
The industry consortium dedicated to sustaining the quality, integrity and dissemination of Serial ATA (SATA) technology, today announced that SATA Express, a new specification that standardizes PCI Express (PCIe) as an interface for client storage, has started the ratification process. The specification has moved into the member review stage, the final step prior to the specification's release to SATA-IO members. SATA Express will be available to the general public in the next version of the specification, expected to be completed in 2013.
SATA Express enables an ecosystem for client storage in which SATA and PCIe solutions can coexist, providing a low-cost solution to fully utilize the performance of next generation solid state drives (SSDs) and hybrid drives. PCIe technology enables interface speeds of up to 1GB/s per lane in the client space, as compared to today's SATA technology at 0.6GB/s. Storage devices not requiring the speed of SATA Express will continue to be served by existing SATA technology. The specification will define new SATA Express device connectors and motherboard connectors that will support both new PCIe drives and existing SATA devices. See this page for more details.
"SATA-IO members have worked together to create the SATA Express specification to bring the scalability of PCIe to client storage," said Mladen Luksic, SATA-IO president. "This industry-wide effort has made a new level of performance available to client applications and enables connectivity to SATA Express enterprise hosts via the SFF-8639 multifunction connector."
The Complete SATA Ecosystem
SATA Express is one of several specifications from SATA-IO designed to offer low-cost, high performance storage solutions optimized for specific device segments. Since its introduction in 2001, SATA technology has penetrated 99% of the PC market and evolved to provide options for a number of applications beyond traditional hard disk storage. SATA is now implemented in a variety of applications including solid state and optical drives, embedded mobile devices, consumer electronics products and enterprise storage. Key specifications for implementing SATA technology beyond the HDD device segment include:
mSATA: A low-profile solution for mobile computing devices and other small form factor applications.
SATA Universal Storage Module (USM): An integrated SATA interface for providing portable, volume storage I/O to consumer electronics devices, as well as PC applications.
SATA microSSD: An embedded, single-chip solution that connects directly to the motherboard to enable ultra-thin form factor devices.

i will be watching this to see how it evolves wonder how many lane this will support from the start

Am I the only one that's not overly happy with SATA-IO and their lack of future proofing? 1GB/s is not even double the current bandwidth maximum of SATA3.
SATA3 was already being saturated by single SSD's on sequential read and write shortly after it's implementation. Granted, that's not Random I/O, but the point is the SSD tech available today seems to be, at least, somewhat limited by the interface.
I only see the same thing repeating itself with the implementation of SATA(4?)
I'd be much happier to see the interface have a max throughput of something like 4GB/s, where SSD tech would take a couple years before it could really begin coming close to saturating the bus.
Just my 2 cents, perhaps my thinking is flawed on this, however?
EDIT: D'oh, I must've missed the part where it says 'per lane'. This actually sounds pretty promising now. Like what was said previously, I would like to know how many lanes can be dedicated to this?

if you want more speed you can already use ramdisks or ssds that have a pcie interface. the advantage of using pcie lanes for harddisks as a standard is removing the need for current s-ata2/3 controllers and the interface surrounding them. ALOT of pcie lanes are unused in current generation systems.
the only way to realy saturate the pcie lanes is to run sli/xfire and jam up every single place you can plug in anything on your board. most ppl use 8/16 at most and have a huge amount of lanes that are just sitting there waiting for something to happen.
sata was a very neat development that got us all away from the ide interface. most ppl couldnt afford scsi at the time of the big ide boom. now that harddisks are growing in size and also in speed, it is a step in the right direction.

This is the MAIN reason why i invested in a PCI-E Solid State Drive. PCE-E SSD
I hope SATA 4 will be something like intel Thunderbolt, and not just a stupid speed bump!

Thats more like it.
I guess I'll be getting a new PC about the time thats released
