Are there any small factories for hard disks?

We do have domestic manufacturers of desktop hard disk drives, such as the Great Wall Hard Disk Drive and Ecto Hard Disk Drive, whose origins are located in Shenzhen, Guangdong Province. Later on, Great Wall and Ecto merged. There were OEM hard disks for ibm.

And micro hard disk production company also exists in the country, such as the South Huitong and Guizhou Shihua, its origin is in Guizhou. Mainly produces 1.0 inch micro hard disk and 1.8 inch hard disk. I don't know what the status is now.

Overseas, when the Maxtor was acquired by Seagate, and ibm hard disk was also acquired by Hitachi.

All of the above was back in the day

Currently the mainstream international hard disk manufacturers are Seagate, Samsung, Hitachi, Western Digital, Toshiba, and Fujitsu. And the latter two companies have had recent news about mergers and acquisitions. (Excluding the SSD category)

The DragonBox uses a 2.5-inch laptop hard drive.
