today announced the release of the Ultra ATA/133 hard drive interface specification, which boosts data transfer rates between a computer and the hard drive up to 133MB per second.
The new interface is one-third faster than earlier record-breaking Ultra ATA/100 technology integrated in most personal computer systems and performance adapter cards sold today. Currently, VIA Technologies Inc., Silicon Integrated Systems Corp (SiS), Adaptec, Promise Technology Inc., and Silicon Image have formally completed licensing agreements to use Maxtor’s Ultra ATA/133 interface technology in upcoming systems and chipsets.
“Maxtor’s Ultra ATA patented technology has been the de facto standard since 1996,” said Vic Jipson, executive vice president of engineering for Maxtor. “The Ultra ATA interface has been one of the computer industry’s most important achievements and can be found on almost 90 percent of all hard drive, CD-ROM and DVD equipped systems shipped in the world today.”
ATA or Advanced Technology Attachment defines the connection and speed for the interface between the hard drive and the computer. As the industry introduces faster and higher capacity hard drives, work has to be done in parallel to speed up the interface between the drive and the host computer in order to avoid a data bottleneck from the drive outperforming the interface.
For example, the new Ultra ATA/133 interface, which Maxtor is branding as “Fast Drives,” is ideal for transferring large amounts of data such as digital video, according to Jipson. The Fast Drives specification and licensing rights for Ultra ATA/133 are now available from Maxtor under non-disclosure.
The Ultra ATA/133 interface uses Maxtor patented technology that was previously incorporated into the highly successful Ultra ATA/66 and Ultra ATA/100 interfaces. It is also backward compatible with the existing ATA standard. (For reference, the new Power Mac G4s introduced at Macworld New York have Ultra ATA/66 hard drives.)
