and to think we used to run a mainframe off a 128Kb fixed hard disk, to run personnel management of the RAF...
 
My first PC had a 40mb hard drive and I remember thinking "I'll never fill that!"

Yeah. Our first 10GB hard drive at the NHS many moons ago, was in a cabinet about 6 foot tall with dedicated psu and aircon.
We had multiple removable platters (layers of disks) and they were only 80MB each
 
Saying that. The NHS had very good DR back in the 80’s.
There were regional computer centres, each with identical main frames.
Everything was based on removable media.
Do we could just take all our media to another centre and run say our weekly or monthly payroll
 
  • Seagate Exos M 36TB
    : This is the highest-capacity single HDD available as of July 2025, using Heat-Assisted Magnetic Recording (HAMR) technology.
  • It is mainly sold to enterprise customers, not standard retail channels.

Enterprise customers? Is that a “Beam it up Scotty” item?
 
The Enterprise would probably have had memory in the kB range rather than MB, GB or TB!

The earliest built computer I worked on (mid 80's ) used perforated paper tape loading for loading the program and had ferrite core memory....

My first for work used paper tape input, mag tape for data files, and the aforementioned fixed disk for the OS, with 4k of ferrite core memory - a Univac 1106 vintage late 1960;s which I met in 78. I then moved onto an ICL 2980 with 200Mb exchangeable disks and 4Mb main memory. Punched cards for data input. Happy days, programming in Assembler and then COBOL, debugging Octal and then Hex dumps.

Yeah ours was punch cards and printers with paper program ribbons.

Probably the most fun job I could have had at 20.

Box of top shelf mags under the desk, read at any time and no one batted an eyelid.
Alcohol keep under the false floor where it was cool.
Playing rugby with a cushion in the main room, once we hit the emergency power off button and all got an almighty roloking.
On evening shift after clay shooting I would take my shotgun in and clean it during my lunch break. No body cared.
Occasionally when on my own waiting for the security guard I would set up an air rifle range using scrap paper and boxes which were plentiful.
One evening I was on call and took the dog in with me and let her wondering around whilst I fixed the issue. When I got home I hoped she had not left any little messages on the carpet.
Knew what every single person got paid as we printed off the pay slips.
Regularly set the alarm off with the smoky exhaust of the generator, fire brigade we’re not impress as they had to send 2 engines down if the got called to the hospital.
If the modem phone rang by accident, the youngest was sent to prank the caller.

Meet my now wife there on our first day as computer operators

My involvement was mainly with the hardware of data-logging systems.... Looked after a few DEC PDP11 series systems with the older ones using 8" floppies for archiving and later built systems using RL02 Drives..... Looked after a couple of Commodore PET based systems that were used for monitoring process temperatures which were museum pieces by the time they were replaced!!! Was getting trained on VAX based systems but then decided on changing to a different role and working shifts which gave me a much better work/life balance which had the added benefit of a substantial pay-rise too!!!
