Seagate Barracuda 7200.14 2TB hard disk preview: Extremely fast 7,200rpm hard drive

At the start of 2012, Seagate launched a new series of 3.5in hard drives, called the Barracuda 7200.14. These are interesting because they have 1TB platters, which is a new milestone. The high data-density has two advantages: more MB per square centimetre always results in better performance, and less platters means lower prices.

It's interesting that Seagate views the new Barracuda as the successor to its entire line-up of 3.5in disks. Last year it consisted of the Barracuda Green (5,900rpm, energy-efficient), Barracuda 7200.12 (7,200rpm, standard) and Barracuda XT (7,200rpm, high-end). Seagate claims that the new hard drives are now so efficient that there is no longer a reason for a Barracuda Green series. Barracuda XT is also end-of-life, and will eventually be replaced by hybrid HDD/SSDs. What happened to the 7200.13 is unclear -perhaps in a bout of superstition they decided to skip it.

We tested the 2TB version of the Seagate Barracuda 7200.14, which you can recognise by the product code ST2000DM001. You can find this for an average price of £90, which is quite affordable for a 2TB disk. You have to pay quite a bit more for a Hitachi 7K3000 2TB or Western Digital Caviar Black 2TB. Seagate's newly acquired Samsung brand only has a 5,400rpm 2TB drive available for that price.

The hard drive uses the SATA 600 interface, and has a 64MB cache. According to Seagate it should have an average transfer rate of 156MB/s, and an average access time of 8.5ms. Those are good stats for a 3.5in 7,200rpm drive.

We tested both 4TB hard drives with our standard hard disk benchmarks. To provide comparison material, on the following pages you will find all recent 2TB, 3TB and 4TB drives we have tested recently, in addition to the Western Digital Raptor 1TB.
