Seagate New Barracuda XT 3TB Review

Testing:

Crystal Disk Mark 3.0: Crystal Disk Mark is a hard drive benchmark designed to measure the read and write speeds of drives by using 4k blocks, 512k blocks, and sequential data. For the test, we chose the 1000MB option.

In the sequential read and write testing, the new 3TB drive is easily ahead of the old drive. In the rest of the testing, the drives are more evenly balanced in performance.
