Serial ATA II specs officialy announced

At yet another IDF session (in Barcelona) Serial ATA Working Group officially announced final specs of Serial ATA II or Serial ATA 300. Besides, they for the first time introduced specs of new SATA cables and connectors designed for some newer applications.

Serial ATA II specs define up to 3Gbps (300MB/s) throughput that doubles the performance of the previous standard version.

It has been already announced that first Serial ATA II products are to go on sale in a month after the standard is fully approved. At that, the new technology won´t require any newer connectors and cables to support higher bandwidths.

Besides doubling SATA 1.0 physical-level performance, the new specs also defines higher-consumption version for computing centres. These external physical-level specs are only to be used to connect whole storage systems and is not meant for single drives.

As for the new (second) version of cable and connector specs, it defines several new connection types:

  • Internal multichannel cables and sockets to speed up port and device interconnects onboard
  • External cabling and connectors to use Serial ATA for connecting external storage systems
  • External multichannel cables and sockets for computing centres allowing for several Serial ATA connections per PC.

Products utilizing new cables and connectors are expected by the year-end.

Currently Serial ATA Working Group includes Serial ATA 1.0 Working Group and Serial ATA II Working Group that, in their turn, include 153 companies, including Dell, Intel, Maxtor, Seagate, Vitesse, etc.
