The '''ProFile''' (codenamed '''Pippin'''<ref>{{cite book |last=Linzmayer |first=Owen W. |title=Apple Confidential 2.0 |url=https://archive.org/details/appleconfidentia00linz_028 |url-access=registration |year=2004 |page=[https://archive.org/details/appleconfidentia00linz_028/page/n52 41] |isbn=1-59327-010-0 |publisher=[[No Starch Press]] |lccn=98-49132}}</ref>) is the first [[hard disk drive]] produced by [[Apple Inc.|Apple Computer]], initially for use with the [[Apple III]].<ref name=release1983 /> The original model had a formatted capacity of 5 [[Megabyte|MB]] and connected to a special interface card that plugged into an Apple III slot. In 1983, Apple offered a ProFile interface card for the [[Apple II]], with software support for [[Apple ProDOS]] and [[Apple Pascal]].

Additionally, in 1983, Apple introduced the [[Apple Lisa|Lisa]] computer, which was normally sold with a ProFile.<ref>{{cite book |chapter-url=https://books.google.com/books?id=qZiwCwAAQBAJ&pg=PA166 |chapter=LISA PERIPHERALS: Disk Drives |title=Microcomputer User's Handbook: The Complete and Up to Date Guide to Buying a Business Computer |editor1=Dennis Longley |editor2=Michael Shain |publisher=The MacMillan Press |year=1983 |isbn=9781349067374 |doi=10.1007/978-1-349-06737-4 |page=166 |quote=...The Lisa is supplied with a Profile 5-1/4 inch hard disk unit providing a further 5 Mb of storage.

Up to three such interface cards could be installed, so in principle up to seven ProFile drives could be used on a Lisa.

The 5 MB ProFile was Apple's first hard drive, and was introduced in September 1981 at a price of {{USD|3499}}.<ref name=oldcomp /><ref>{{cite magazine |url=https://books.google.com/books?id=ej4EAAAAMBAJ&pg=PT1 |title=Santa Clara Systems |type=Advert |magazine=[[InfoWorld]] |date=15 February 1982 |page=46 |quote=Comparison table: ''...Apple ProFile / Integrated Backup: None / Error Correction : None / Capacity Formatted: 5 MBytes / Avg Seek Time: 95 ms / Suggested List : $3495...'' |access-date=October 17, 2021 |archive-date=October 17, 2021 |archive-url=https://web.archive.org/web/20211017025548/https://books.google.com/books?id=ej4EAAAAMBAJ&pg=PT1 |url-status=live }}</ref> Later,{{when|date=May 2018}} a 10 MB model was offered, but required an upgraded [[Programmable ROM|PROM]]/interface card to recognize the additional 5 MB.{{cn|date=May 2018}}

Internally, the ProFile consisted of a bare [[Seagate Technology|Seagate]] [[ST-506]] [[stepper motor]] drive and mechanism, without the usual Seagate electronics, a digital and an analog circuit board designed and manufactured by Apple, and a power supply.

Later Lisa models could be configured with an internal 10 MB "Widget" [[Voice coil|voice-coil]] drive with a proprietary controller designed and built entirely by Apple, but the Widget was never offered as an external product for use with other Apple computers.

Apple did not offer another hard drive until it released the [[Hard Disk 20]] designed specifically for the [[Macintosh 512K]] in September 1985 which could not be used on the Apple II or III families, or Lisa series. The ProFile could not be used on the Macintosh or the [[Apple IIc]] (for which Apple never offered an external hard disk drive of any kind).

By September 1986, the ProFile would be superseded by the introduction of the first cross-platform [[Hard Disk 20SC]] [[SCSI]]-based drive for the Macintosh and interface card for the Apple II family (excluding the IIc series, which had no SCSI interface of any kind) and Lisa/XL series.
