IDF: Seagate, Intel and Silicon Image showcase Serial ATA II
Yesterday Seagate posted an interesting press release, reporting about the demonstration of new Serial ATA II capabilities at Intel Developer Forum. Today even Serial ATA 1.0 are not well-presented in the market, but Seagate, Intel and Silicon Image are already preparing Serial ATA II.
The main difference of new specification is Native Command Queuing to significantly extend device and basic storage functionality. Using Native Command Queuing, controller will analyze processor requests and queues them to maximize transfer rate and minimize access time. Besides, Serial ATA II controllers will be able to organize request queues and perform them without any processor interference.
For the demo, companies used Silicon Image SATALink SiI 3112A PCI-Serial ATA host controller and Seagate hard disk prototype; the whole system worked under Intel software.
It´s interesting that the press release dates the Seagate Serial ATA hard disk release to the next quarter. So, let´s be patient and wait.
