Seagate 750GB Barracuda 7200.10 Serial ATA Hard Drive

Seagate has always been at the forefront of pushing the capacity of their desktop drives. With the release of the Barracuda 7200.10 hard drive, they were the first to achieve the remarkable single-drive capacity of 750GB.

Of course, Hitachi has recently upped the ante by beating Seagate to the 1 TB (terabyte) line. Still, it's a matter of time before Seagate releases their own TB capacity hard drive. We will be eagerly awaiting the opportunity to test one when it is released. In the meantime, we still have 750GB of storage goodness in the Barracuda 7200.10!

The Barracuda 7200.10 is not the first Seagate desktop drive to support the new SATA 3Gb/s transfer protocol. Neither is it the first Seagate desktop drive to support NCQ (Native Command Queuing). But it is the first 3.5" drive from Seagate to feature the new Perpendicular Recording technology which we first saw in the Seagate Momentus 5400.3 hard drive.

Thanks to Perpendicular Recording, this drive features a much greater areal density, giving it not only more storage space but also a higher platter-to-buffer transfer rate. In fact, that's just what we saw in our test results - significantly higher transfer rates than the Barracuda 7200.9 hard drive.

If you are looking for the largest-capacity desktop hard drive from Seagate, well, the Seagate Barracuda 7200.10 is your man for the job. It not only comes with a high capacity of 750GB, it also has much better performance than its predecessors even though they are all running at the same spindle speed.

You will also be glad to know that it comes with a magnificent 5-year limited warranty. While this does not guarantee that this hard drive won't quit on you in the next five years, it does show the amount of confidence Seagate has in the reliability of this model.
