In Korean, it is common to use the term “하드” (“hard”) to mean a drive on a computer, like “hard drive” in English. Unfortunately, in English, the meaning of “hard” is closer to “딱딱한” or “어려운” than anything computer related.
Instead, the best way to express this one is either “hard drive,” for the drive on your computer, or “the cloud,” for saving it remotely. For example, “Save it to the cloud,” or, for downloading, “Download it from the cloud.” A longer example is, “I saved the document to the cloud.”
