This hard drive is part of Seagate's high-end and high-performance XT range, and to make sure it doesn't disappoint, the 2 TB Barracuda XT has a 6 Gbps SATA-3 interface, a spin speed of 7200 rpm and 64 MB of cache memory.
The CrystalDiskMark test gives results that place the Barracuda XT neck and neck with its WD rival. However, it doesn't do quite so well at writing medium-sized files:
The results of the AS-SSD test confirm those seen with CrystalDiskMark:
The access time test—also carried out with AS-SSD—shows the Barracuda XT lagging behind the Caviar Black, which is the second-fastest hard drive we've tested in this field (just after the unbeatable WD VelociRaptor 600 GB):
The Barracuda XT got a score of 5388 while the Caviar Black managed 5702.
Our more practical tests showed that the differences in performance between the Barracuda XT and the Caviar Black aren't always that noticeable in reality, and they certainly depend on the type of program used:
- Good performances
- Huge storage capacity
- Write performances a little disappointing
- Gets a bit hotter than the average drive
Although its write speeds aren't quite as good as the WD Caviar Black, the Barracuda XT is still a very good hard drive. It will, however, need to come down in price before it makes a serious and attractive alternative to the WD.
