We took a look at both of WD’s 4TB hard drive options in the past month, so it’s a great time to get some Seagate action going. The Constellation ES.3 competes with WD’s RE in the enterprise space, but it brings an interesting feature to the table: a 128MB cache. So let’s give the the drive a good test and see if it can topple the RE drive we raved over.
One of the best-known storage benchmarking tools is HD Tune, as it’s easy to run, covers a wide-range of testing scenarios, and can do other things such as test for errors, provides SMART information and so forth. For our testing with the program, we run the default benchmark which gives us a minimum, average and maximum speeds along with an access time result, and also the Random Access test, which gives us IOPS information.
Seagate’s ES.3 drive continues to perform very well here, beating out everything aside from WD’s VelociRaptor in the throughput tests, and coming ahead of that in the write access time test.
A trend that’s becoming obvious is that Seagate’s ES.3 drive is a great performer where writes are concerned. In most read tests, it goes head-to-head with the WD RE, but in the write, as with the graph above, it inches ahead. The gains are not “blow it out of the water” good, but it’s undeniable that Seagate has an edge here.
