Seagate Unveils Momentus XT 750GB Solid State Hybrid Drive

Seagate has unveiled its third generation Momentus XT drive, which comes with 8GB SLC NAND Flash plus a 750GB traditional magnetic spinning hard disk drive.

Other key features include a 6Gbps SATA interface with NCQ, a 2.5-inch form factor and, according to Seagate, up to 70 per cent better performance. There is also a smaller 500GB model which has 4GB flash and a 3Gbps SATA interface.

The storage giant has come up with a fancy new technology called FAST factor which "give(s) you the instant-on response of solid state memory and the extremely large capacity of a hard drive."

FAST factor works with Seagate's Adaptive Memory technology to deliver even more oomph for the money. Based on Seagate's own benchmark, the new Momentus XT is faster than even a MacBook Air which comes with a solid state drive.

According to the Register (opens in new tab), the FAST Factor is where the magic works. Seagate told the publication that the "brains of the SSD hybrid drive" are 100 per cent internal to the drive, that it is a proprietary design, that it works with any SATA driver and is transparent to the OS.

The drive carries a suggested retail price of $245 in the US, and while the 500GB model costs around £138 in the UK, we suspect that the 750GB model will reach around £200.
