Hitachi HDS721010DLE630 is a hard drive model created by Hitachi. Produced shortly before the transfer of most of Hitachi's 3.5" IP to Toshiba, the latter company also sold these hard drives rebranded under the TOSHIBA DT01ACA100 for a time, but still reported (over ATA_IDENTIFY) using the Hitachi model number. Beginning in around December 2012, the ATA_IDENTIFY name was fully changed to TOSHIBA DT01ACA100 and all mentions of Hitachi on the label removed, effectively discontinuing the HDS721010DLE630 in its original form, though the DT01ACA100 is still in production and is mechanically identical to the HDS721010DLE630.
Competing drives include the various incarnations of the WDC WD10EZEX and ST1000DM003.

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.
- Hitachi HDS721010DLE630s sold by Toshiba have two serial numbers; a standard serial number assigned by Hitachi using their scheme and is used over ATA_IDENTIFY, and a T S/N, assigned by Toshiba, which replaces the first three characters with a Toshiba-style date code (e.g. 924 to indicate a September 9, 2012 manufacture date), and adds four characters to the end (one seperated by a space from three more, similar to most Toshiba serial numbers). Fully integrated DT01ACA100s have standard Toshiba serial numbers which fully follow their scheme, including using a trailing S on the first block to indicate the country of manufacture, China, the only factory used for Hitachi HDA drives (Toshiba's Phillipines factory do not make them).
