Seagate Barracuda 7200.10 - Up To 750GB Of Perpendicularly Recorded Data

Seagate published an interesting PDF document describing the soon-to-come Barracuda 7200.10 series utilizing the perpendicular recording. The series will include hard drives of 200GB to 750GB capacity. Like the previous Barracuda 7200.x, newer drives feature 7200 rpm spindles, SATA interface and support Native Command Queuing (NCQ).

Of course, the most interesting are two 750GB models: ST3750640A (Parallel ATA) and ST3750640SA (Serial ATA). According to the description, they will have 16MB cache and 4 plates (and 8 heads).

Pity, but there is no data about seek time, the current bottleneck of perpendicular drives. And the average latency is rated 4.16 ms. Maximum rated throughput is naturally limited by PATA and SATA standard limitations of 100MB/s and 300MB/s, respectively.

The new drives will seemingly be released for desktop machines and maybe even media PCs, though their sound power of 3 bels (seek) and 2.7 bels (idle) might be too high for the latter.
