The very first Apple computers did not have any hard drive at all; they relied entirely on cassette and then floppy disks for storage. Apple’s first actual hard disk product, the external Apple ProFile, had a capacity of 5 MB.

Quick Scoop

  • The Apple I (1976) used cassette tape for storage and had no hard drive.
  • The early Apple II machines also shipped without a hard drive and commonly used 5.25‑inch floppy disks.
  • Apple’s first hard drive product was the Apple ProFile , introduced in 1981 with 5 MB of capacity, sold as an external unit for systems like the Apple III and later the Apple II.

So if you’re asking “how much hard drive capacity did the first Apple computer have,” the historically accurate twist is: the first Apple computer had 0 MB of hard drive capacity , because it didn’t include a hard drive at all. The first Apple hard drive itself, the ProFile, was a 5 MB unit.

In other words, the earliest Apple machines lived in a world of cassettes and floppies; the 5 MB ProFile was Apple’s big leap into hard disk territory.
