硬盘 (yìng pán): Жесткий диск

I saved all my photos and videos on an external hard disk, so I won't worry even if my computer breaks down.

This game is too big; my hard disk doesn't have enough space. I have to delete some old files before I can install it.

The engineer is checking the server's hard disk to see why the data reading speed has become so slow.

Don't forget to regularly back up the important data on your hard disk. If it fails, the loss will be huge.
