SATA-IO finalises 6Gb/s spec

SATA-IO finalises 6Gb/s spec

The new SATA specification offers double the throughput of existing systems at an impressive 6Gb/s.

If you're looking forward to the next generation of ultra-fast solid state storage but are worried that the clunky old 3Gb/s SATA interface is getting too long in the tooth to keep up, fear not: the finishing touches have been put in place in the SATA Revision 3.0 Specification.

The Serial ATA International Organisation – also known as SATA-IO, and representing a consortium of companies behind the popular interconnection specification – has officially launched a final version of the next-generation SATA specification. In a press release – via Engadget – SATA-IO president Knut Grimsrud claimed the finalised spec would allow members to “design for their customers' products with the speed they crave, without compromising the quality and performance they've come to expect from SATA technology.

Fully backwards compatible with existing SATA 3.0Gb/s and SATA 1.5Gb/s drives, the new implementation promises throughput of up to 6Gb/s – twice that afforded by the current SATA specification. This additional bandwidth, along with a new streaming command added to the Native Command Queuing technology to allow improved isochronous data transfers for multimedia playback, should keep even the fastest solid-state disk ticking over.

The news is good for laptop users, too, with the power management facilities of the specification getting an overhaul and a newly designed LIF connector to shrink 1.8” drives still further.

A finalised specification does not a commercial product make, of course – and it may well be a while before we start seeing the first drives offering SATA 6Gb/s connectivity on the market; still longer until motherboards sporting SATA 6Gb/s chipsets appear for sensible money. So far no companies have officially announced a launch schedule, although this is likely to change after the group demonstrates what it describes as “several product implementations of SATA 6Gb/s technology” at Computex Taipei next month.

Are you looking forward to getting your 6Gb/s schwerve on, or does storage technology in general need to improve before we can make use of the extra bandwidth on offer? Share your thoughts over in the forums.

Coooooool... this and some nice big drives seems really... tasty!

No, no, no!

Especially when you mentioned SATA 3.0Gb/s earlier in the article.

I'd say it'll be 1 year from now until availability and price are acceptable. Otherwise it sounds interesting, but it already did before they finalized the specs.

//ninja-edit: Calm down buttercup, SATA 3.0 will be the name for this in public anyways. And now we can at least say Bit-Tech started it. :D

Sounds good, and it's a good time for the technology too what with drives finally offering good data rates. Another year or 2 and hopefully this will be available at an affordable price.

So why is it 6Gb/s ?

Is that the maximum speed the current level of technology allows or did someone explicitly decide on that number?

I'm curious to know if 6Gb/s really is the max they can do for this new spec. Feels like it shoudl be much higher... :|

Has anything saturated the sata 2.0 3GB/s bus?

But if they did they wouldn't be able to cash in as often as they want to. After all they're just a bunch of people sent to those meetings by their companies to make sure the next version gives enough new and shiny advantages to make people buy it but not too many to give them the chance to squeeze just that tiny little bit more out of us.

Nothing saturates SATA 3Gb/s anyway, we're limited by sustained read/write speeds, which still suck on mechanical drives. Once flash drives become viable this'll be relevant, though, hopefully.

The Gigabyte GA-EX58A-Extreme, SATA 6GB/sec, got the Computex best motherboard Award.
