Toshiba DT01ACA100 1TB preview: Toshiba's first 3.5-inch hard disk

In March, 2011 Hitachi sold its hard drive division to Western Digital (opens in new tab). Under pressure from the EU and the Japanese competition watchdog, Western Digital was forced to sell off the 3.5in Hitachi division to Toshiba. Until that point Toshiba only made 2.5in disks, but the acquisition of Hitachi has enabled the company to offer 3.5in hard disks as well.

The models they're currently selling are still in fact Hitachi disks, only with a Toshiba sticker. The Toshiba DT01ACA100 1TB that we're reviewing here is an example of just that.

Toshiba sent us one of their new 3.5in disks, the DT01ACA100 1TB. Hardware-wise it is identical to the Hitachi Deskstar 7K1000.D 1 TB. Moreover, the sticker carries both Hitachi's old product code (HDS721010DLE630) and Toshiba's new code product code. It's interesting that Toshiba doesn't tend to give its products names that you can pronounce or remember. Product names such as 7K1000.D, Caviar Black or Barracuda 7200.14 are still manageable, but something like DT01ACA100 doesn't seem very consumer-friendly from a marketing perspective. It doesn't exactly facilitate word-of-mouth advertising.

The DT01ACA100 is a 1TB disk running at 7200 rpm. It has a single 1TB platter, which puts it in the same family as the Hitachi Desktop 7K400 4TB which has four of them. The hard disk has a Serial ATA 600 interface and 32MB of cache.

The average price is £58, which is slightly more than what it costs under its old Hitachi name. The main competitors for this products are the Seagate Barracuda 7200.14 1TB (£58) and the Western Digital Caviar Black 1TB (£75).
