TOSHIBA DT01ACA100 is a hard drive model created by Toshiba. It is based on the Hitachi HDS721010DLE630, with Toshiba labelling and drive revision numbering. It, along with the TOSHIBA DT01ACA025, TOSHIBA DT01ACA032 and TOSHIBA DT01ACA050, is the first consumer-targeted 3.5" hard drive model to be released by Toshiba.
Competing drives include the various incarnations of the WDC WD10EZEX, ST1000DM003 and ST1000DM010-2EP102/ST1000DM010-2DM162.

Trivia
- This hard drive, like most Hitachi desktop drive firmware (dating back all the way to the IBM Deathstar family), has a bugged Power-off Retract Count counter; it always matches Load/Unload Cycle Count, even if the hard drive has always been powered down normally. It can sometimes exceed Power Cycle Count, which is also illogical. The SMR 1-platter variant based on the same HDA, TOSHIBA DT02ABA200, does not exhibit this issue due to it running native Toshiba firmware; the Power-off Retract Count increments independently from Load/Unload Cycle Count.
- Early hard drives (prior to around December 2012) reported using the Hitachi model number, Hitachi HDS721010DLE630, instead of TOSHIBA DT01ACA100 like modern units do, bore the Hitachi logo in addition to the Toshiba one, and used a monospaced font for drive details, as opposed to the Arial-like font used on modern Toshiba units (see gallery for example and the Hitachi HDS721010DLE630 page for more details).
- Another Hitachi design trend that was later phased out was the date code, which, prior to October 2019 (when the Toshiba DT02 series was released), listed only a three letter month and a year, seperated by a dash. However, the serial number contained the date. For example, in the page image, the date code is APR-2019, but the serial number's first three digits, 49U, reveals the drive was manufactured on 30 April 2019. Starting from October 2019, all Hitachi HDAs switched to the date code seen on mobile Toshiba MQ drives, such as "23OCT2019", without requiring decoding the day from the serial number date code. For example, if this date code were used on the page image drive, it would read "30APR2019".
