HDD Seagate Barracuda 7200.10 320 GB brandnew Philippines

The 7200.10's biggest advantage over its predecessor is maximum total capacity. Older Barracuda 7200.9 drives topped out at 500 GB, but the 7200.10 is available in capacities as high as 750 GB. Curiously, though, Seagate doesn't offer a mid-point between 500 and 750 GB flavors of the 7200.10. The 7200.10 isn't available in capacities lower than 200 GB, either. However, with 250 GB Barracuda 7200.10s selling for less than $100 online, there's hardly a need for lower capacities. The 7200.9 line should be available for some time, as well.

With perpendicular recording and higher capacities, the Barracuda 7200.10 line obviously boasts higher areal densities than its predecessor. How much higher depends on which drive you compare. The 750 GB Barracuda 7200.10 packs an impressive 188 GB per platter, and although that areal density is only 15% higher than 160 GB versions of the 7200.9, it's 34% higher than 500 GB models. We were unable to confirm the platter sizes of other capacities in the 7200.10 line, but Seagate assures us all use perpendicular recording technology.
