The very first Apple computer, the Apple I released in 1976, did not have a hard drive. It was a motherboard-only personal computer kit with no built-in or optional hard disk storage; storage was typically done via cassette tape

. Apple's first hard disk drive product came later with the Apple ProFile, introduced in September 1981 as an optional peripheral for the Apple III. The ProFile had a formatted capacity of 5 MB

. Therefore, the original Apple I had no hard drive capacity, and the first Apple hard drive available was the 5 MB ProFile in 1981.
