seagate barracuda 7200.10 320gb hard drive

The 750GB 7200.10 is the version which has the most capacity per platter, but while the headline capacity figure of 750GB is certainly eye-catching, the areal density increase isn’t as great as you might think. You always get some variation of platter density across a family of drives in order that models can be sold with a nice round number of Gigabytes of capacity, and in this respect the king of the 7200.9 family was the 160GB version which was a single platter design. Seagate’s previous holder of the capacity crown was the 500GB 7200.9, which also used a four platter/eight head design to give an areal density of 125GB per platter. This is surely the first time that a 200GB drive has ever been the baby of a new range of drives. The 750GB, 500GB, 400GB, 320GB models all have 16MB of cache, the 250GB comes in both 8MB and 16MB versions, while the tiddly little 200GB model has a mere 8MB cache. There are six different capacities of drive in the 7200.10 range with a choice of ATA100 and SATA 300 interfaces. In other respects the 7200.10 is a conventional SATA300 hard drive, with a 7,200rpm spin speed and support for NCQ (Native Command Queuing) so we’re going to dwell on the areal density and 750GB capacity throughout this review. The result is a significant increase in areal density so we’ve leapt from the 500GB of the Barracuda 7200.9 to an enormous 750GB from the Barracuda 7200.10 family.

Perpendicular technology stands the particles of magnetic media on their end instead of laying them on their side. The major feature of Seagate’s new Barracuda 7200.10 hard drive is the use of perpendicular recording technology that boosts the capacity of the drive by an impressive percentage.
