Drives Get Bigger, Faster, Cheaper

9.1-GB drives spinning at 7200 rpm will soon enter the mainstream.

Despite many competing technologies, hard disk drives continue to hold their dominant position as the medium choice for data storage. The price of hard disks continues to plummet, while capacity and performance climb upward. Seagate and Quantum are expected to ship 9-GB Ultra2 SCSI drives in mid-1998. The 3.5-inch-factor drives, which stand just 1 inch high, spin at 10,000 rpm.

The higher the rotational speed of the disk drive motor the greater the data transfer rate, and the lower the seek and latency times when the head switches tracks. Today, most hard disks spin at 5400 rpm, with higher-end models attaining a speed of 7200 rpm. The Seagate Bar-racuda, Quantum Atlas, and Micropolis Tomahawk 7200 drives have become popular in multimedia applications such as digital motion pictures.

Seagate is already shipping its first 10,000-rpm disk drives, the Cheetah family. With formatted data transfer rates peaking at 16.8 MB per second (around 40 percent better than top 7200-rpm hard drives), and prices around 40 percent higher than equivalent 7200-rpm offerings, these 4.5- and 9.1-gigabyte drives are currently limited to niche market applications. Early next year, however, Seagate will sell a new drive, the Medalist Pro 9140, that has a 9.1-GB capacity and spins at 7200 rpm. Street price will be about $495, according to Denise Lippert, product marketing manager.
