Throughout our tests, the Seagate Barracuda 3 TB exhibited a very good level of performance, beating both the comparison drives in almost all of the tests.

In CrystalDiskMark, the Barracuda 3 TB showed the best level of performance in the Sequential test and Random test using 512 KB blocks, although it was beaten by both drives in the random read and write tests using 4 KB blocks.

Regarding HD Tune, the Barracuda 3 TB beat the other drives in every test by a significant margin, except the burst transfer rate where it achieved the same result as the Barracuda Green 2 TB. These results were also reflected in the access time test, where the Barracuda 3 TB achieved the best level of performance.

For many consumers, the cost of a hard drive is even more significant than the performance. When we consider the relative cost and performance of the Seagate Barracuda XT 2 TB, we can’t see why anyone would even consider purchasing it. Despite costing more than the Barracuda 3 TB, it offers a smaller capacity and an inferior level of performance.

As 3 TB hard drives are relatively new to the market, it’s not surprising that the Barracuda 3 TB costs slightly more per gigabyte than the smaller Barracuda Green 2 TB. More advanced users may consider purchasing two of the Barracuda Green 2 TB drives and setting them up in a RAID0 array, as this would create a 4 TB virtual drive with greater performance than the individual drives.

However, for less advanced users, the Barracuda 3 TB still offers reasonably good value for the money and is perfect for those building a home server or multimedia PC.
