Seagate Barracuda XT 2TB
11 January 2010
Excerpt: When Seagate told us it would be shipping the first 6Gb/s SATA hard drive, we were a little surprised. And when we found out it wasn’t going to be a solid state drive, but a 7,200rpm Barracuda drive, our skepticism increased. Sure, we’d been waiting a long time for Seagate’s 2TB 7,200rpm drive, and it’s nice to see the SATA 6Gb/s spec ship on a real-world product, but putting a 6Gb/s controller on a mechanical hard drive is like putting a Formula 1 airfoil on a golf...
Pros: 100MB/s-plus reads and writes; props for early adoption of 6GB/s SATA.
Cons: Performs better on 3Gb/s SATA; can't match WD Caviar Black; 6Gb/s SATA is unnecessary.
Summary: We were expecting Seagate Barracuda XT 2 TB to smash its main competitor, Western Digital Caviar Black 2 TB, because of the use of the new SATA-600 interface, but this didn’t happen: both achieved the same performance level. In fact, Western Digital Caviar Black 2 TB achieved a somewhat lower access time; so if you are looking for a fast 2 TB hard drive, Western Digital Caviar Black 2 TB has a little bit of an advantage.
Excerpt: Seagate's 2TB Barracuda XT is the first internal hard disk we've seen to use the new SATA 600 interface. On paper, it can transfer files at a top speed of 600MB/s, which is twice as fast as the existing SATA 300 interface. We didn't expect the Barracuda XT to come anywhere near its theoretical top speed in our file- transfer tests, but we were still surprised that it was no faster than the quickest SATA 300 disks.
