Barracuda ATA V will also offer a native Serial ATA interface - a faster,
simpler, more intelligent technology designed to replace today’s Parallel ATA
hard drive interface.
ATA V will begin shipping next month with the Ultra ATA/100 interface; the
native serial ATA option will be available this fall. Seagate and Intel are
demonstrating the Barracuda ATA V with its native Serial ATA interface this week
at PC Expo in New York.
Barracuda ATA V builds on the proven technology of its extremely successful
and reliable predecessor, ATA IV. The new disc drive is ideal for
high-performance PCs, home entertainment PCs, NAS and entry-level ATA servers.
It V a PC hard drive internal transfer rate of 570 Mbits per second and a 9-msec
seek time. The Ultra ATA/100 version features a 2-Mbyte cache, and the Serial
ATA version will sport an 8-Mbyte cache, the largest on any PC hard drive.

Seagate’s patented Soft-Sonic Fluid Dynamic Bearing (FDB) motor makes the
fast 7,200-rpm Barracuda ATA V almost too quiet to hear, using the same
technology that made Barracuda ATA IV the first virtually silent PC drive. And
with Seagate’s exclusive 3D Defense System, Barracuda ATA V offers the best
combination of performance, quiet operation and ruggedness.
Soon, Barracuda ATA V will feature native Serial ATA technology. Seagate’s
native technology enables Serial ATA’s full 150-Mbytes-per-second transfer
speed and adds no excess components or slow overhead to reduce performance.
Seagate will first ship the Barracuda ATA V with standard Ultra ATA/100
interface and will then offer its native Serial ATA version in a few months.
