USB 3.0 ad un passo dal rilascio





It seems like everything uses USB today from cell phone chargers to keyboards, mice, printers, and cameras. What many really want are faster USB connections. USB 3.0 has been on the horizon for a while now and for a time the future of the specification and cross compatibility was unknown.
The USB 3.0 Promoters Group announced yesterday that the USB 3.0 specification was finally complete. The specification is a sort of roadmap that allows manufacturers to build controllers and products utilizing the USB 3.0 standard. The specification has now been turned over to the USB Implementers Forum, the managing body for USB specifications.
Members of the USB 3.0 promoters group including -- HP, Intel, Microsoft, NEC, ST-NXP, and Texas instruments -- have had a long road with accusations from non-forum members that it was keeping the completed specification from other manufacturers in order to give member companies a competitive edge in the market.
The accusations led AMD and NVIDIA to announce that they intended to begin work on their own open host controller for USB 3.0. This move was potentially catastrophic for USB 3.0 as different manufacturers would not have been able to guarantee compatibility across platforms for USB 3.0 devices.
USB-IF president and chairman Jeff Ravencraft said in a statement, "SuperSpeed USB is the next advancement in ubiquitous technology. Today’s consumers are using rich media and large digital files that need to be easily and quickly transferred from PCs to devices and vice versa. SuperSpeed USB meets the needs of everyone from the tech-savvy executive to the average home user."
The specification for USB 3.0 debuted at the SuperSpeed USB Developers Conference in San Jose on November 17. Among the new improvements that USB 3.0 will bring are higher data speeds and enhanced power efficiency.
The first USB 3.0 discrete controllers will be available in the second half of 2009 and the first consumer products using USB 3.0 are expected to be available in 2010. The first products to be commercially available for the specification will be flash drives, external hard drives, and digital music players.
Intel, AMD, and NVIDIA went around and around in June with accusations over how complete the open host controller specifications for USB 3.0 were. AMD and NVIDIA claimed the specification was complete and Intel wasn't releasing it in an attempt to gain a competitive edge. Intel maintained that the specification wasn't complete and when it was complete, they would release it to other manufacturers.
This is what led AMD and NVIDIA to announce they were starting work on their own specification for USB 3.0 open host controller. Exactly how far the two firms went with their own specification was never announced. The competing specification was never made available and if the two firms did begin developing their own product and just haven’t released it yet, the project is certainly dead now. It's a safe bet that the first specification to market will be the standard for USB 3.0. An AMD source claimed that it was at work on its own specification in June.

Bella notizia....Quindi se ho letto bene , i primi controller seconda metà del 2009 e invece piena disponibilità nel 2010??

[EmaXOC]

hmmm... veloità di trasferimento di circa 10 volte maggiore allo standard USB 2.0, mica male!
Finalmente le pen drive da up to 32gb lavoreranno benone...
però troppo in là la piena commercializzazione e soprattutto disponibilità... chi vivrà vedrà!

SATA 3.0 comes in 2009




AMD to support it

We've just learned that ATI's SB800 Southbridge, the one scheduled for second half of 2009, is supposed to support brand new SATA 6Gb/s or better known as SATA 3.0 standard.

AMD will be among the supporters and we believe that the hard drive industry will follow. We are sure that SATA 3.0 devices will run a bit faster and you can forget about doubling your performance simply from going from SATA 2.0 to 3.0. Theoretically, SATA 3.0 has doubled the bandwidth that jumped from 3 Gb/s to 6Gb/s and this should bring some performance improvements; but we wouldn't expect huge leaps.

We are sure that Intel and Nvidia, the other major chipset players, will support SATA 6Gb/s as well, but we are not aware of these plans at this time.
