Although they tried this before with little success there’s something to be said for giving it another go. Hybrid technology can be hit and miss, who knows that this new drive will bring. Seagate is offering up a hybrid drive with SSD technology. Boasting SSD performance while attempting to keep prices reasonable.
The SATA drive (dubbed “Momentus XT”) spins at 7200 RPM, has 32MB of DDR3 cache, and 4GB of SSD capacity. This combination can result in faster applications and access to data compared to traditional hard drive technology. Actual platters should only spin 10% of the time reducing energy costs. Frequently accessed data would be stored on the SSD portion of the drive. 250 GB version is estimated to cost $113.
A speed test compares this drive to others and the XT doesn’t come out looking so good. Performance is disappointing. Given the price drops in hard drives you should just probably stick with a pure SSD drive if you’re looking for the best performance.
