Seagate's Momentus XT hybrid drive worth the money
A standard VelociRaptor with 150GB of capacity, sells for $185 at Newegg.com.
The VelociRaptor, with a 10,000rpm spindle speed, is considered by most to be the fastest consumer hard drive on the market. But, the Momentus XT's platter rotates at 7,200rpm, and still beats the VelociRaptor for write speeds. So you can see how that drive's SSD really can boost performance.
It bears noting that I did not test the Momentus XT for its affect on the laptop's battery life. After testing more than a dozen SSDs for this, I've found very little difference between a hard drive and an SSD.
Overall, I like the Momentus XT for several reasons. It is a very fast drive, particularly for data writes, and it has a very attractive price that is likely to only get better as Seagate ramps up sales. Would I recommend this for a tablet or other device that would be left running while in transport? No. In the end, it's still a hard drive with an actuator arm that can damage a disk platter if bumped hard. But I would not hesitate to buy this drive for my laptop for the faster boot-up times, application loads and overall better performance.
