Description
The DK228A-65 was the first Hitachi drive to use GMR heads, which gave a recording capacity of 6.48 GB, about 1.3 times more than conventional MR-head drives. The disk speed was also boosted to 4,200 rpm from the 4,000 rpm of previous models. Together, the GMR head and faster disk speed enabled a maximum data transfer speed of 13.4 MB per second, which improved the drive’s overall processing speed. The drive had an ATA-4 interface, which was the industry standard at the time.
