Seagate is on the verge of announcing a 3.5in desktop hard drive with a capacity of 750GB - increasing the Barracuda 7200.10 line's maximum storage space by 50 per cent. Seagate hasn't formally announced the 750GB model, but it is already beginning to appear on the company's marketing material.

The drive runs at 7,200rpm and contains 16MB of cache memory. Like other models in the line, it has an average latency of 4.2ms. Seagate will offer the HDD with a choice of Ultra ATA 100, 1.5Gbps SATA or 3Gbps SATA interfaces. The Serial ATA versions both support Native Command Queuing (NCQ).

The drive's contains four platters accessed using eight read and write heads. Its capacity is believed to be a result of Seagate's perpendicular recording technology.

Like other such drives, Seagate will offer the 750GB model with a five-year warranty. As yet pricing and availability is not known. ®
