Not well known but Tektronix was a pioneer in desktop computing. They had a huge hard drive available. Management decided to go in a different direction. en.wikipedia.org

IBM 2311 disk drive used in the 360 system. I used similar drives into the late 80's. Don't remember the brand. About the size of a washing machine for 300 Megabytes! 14" platters, I think about 8-10 of them.

re: 2311 I remember the bank(s) of 2314s in the computer room of the bank where I was employed right out of school as the apprentice Assembler programmer for an IBM field rep as he extended CICS to support the 2980 teller banking terminals. It used to take FOREVER to get a dump printed out on the 1403 printer so we could debug whatever caused an abend. We were the first bank in the country to use automated 2980s in daily operations. Remember the IBM Selectric rotating ball typewriters? Futuristic, baby! The disk drives sat on a raised flooring so cold air could be blown underneath them. The room was so darned cold and noisy that nobody wanted to enter it, which was a good thing. That room contained the hard drives and the tape drives that were used as backups for them. The drives were "easily" swapped out during the day to meet whatever data requirements the manually defined operations schedule demanded. Ahhhh, memories. My phone now has more storage and computing capacity than that entire many-million dollar computer room. It's a tad bit faster, too. ibm.com Sure is a pretty day. TED
