Maxtor is set to announce two hard drives today, including one with 160GB of storage space.

The Maxtor DiamondMax D540X, a 160GB hard drive running at 5,400rpm (revolutions per minute), uses Maxtor's ATA/133 ultra advanced technology attachment. This enables data transfer speeds of up to 133MBps (megabytes per second).

Maxtor, which launched the ATA/133 standard in August, said it is 33 percent faster than the previous version.

The second drive, the DiamondMax Plus D740X, is designed as a high-speed drive, rather than one with a large storage capacity. The 740X operates at 7,200rpm and can store 40GB per platter, allowing up to 80GB on a drive, the company said.

Both drives are bundled with ATA controller cards and are backwards-compatible with older ATA cards.

The D540X drive will also be integrated into the MaxAttach NAS 6000, an enterprise-class file server that Maxtor will announce on Tuesday at the Networld+Interop conference in Atlanta, US, the company said.

The D540X will be available from early October, while the D740X is available immediately. Expect to pay between £200 and £300 for it.
