Maybe we've talked about this before-I've got 2 10 TB drives in this computer. Bought in 2019. The only thing I've seen greatly improve in the last 10 years is solid state memory. This computer's C drive is a 2 TB SSD. My first computer was a Tandy 2000 with 256 KB RAM, 8 MHz 80186, and a 8 color 640x400 display running DOS 2.0. It still was $3500 in 1983 $. An original IBM PC was about the same price. A 5MB hard drive for the Tandy was another $1000.
I wonder what the total amount of electronic data stored, worldwide, was when you bought your IBM PC? I bet it could not have been more than a few terabytes.Maybe we've talked about this before-
My first PC was the original IBM PC bought in early 1980s. It had 256kb RAM, monochrome display and 2 floppy drives. I think it cost around $3500. Later I was in Austin looking around in this tiny little computer store and they had hard drive kits for sale. They had a full height 10MB kit for $400 and a 20MB half height kit for $450. I had not idea what I would use the additional storage for of the 20 vs 10 but I bought the 20MB kit. Well famous last words... eventually I bought a second 20MB drive, then took both of those out and replaced by a single 60MB RLL drive, then a 105MB IDE drive, then 383MB ESDI, then a 676MB ESDI. Now my desktop computer has a 1TB SSD boot drive and a 4TB SSD data drive. I have a couple of 5TB portable mechanical drives for backup. Maybe 5 years ago I was using 2TB portable mechanical drives for backup. I showed one to my wife and told her it had 100,000 times as much storage as my first hard drive and quite a bit smaller maybe 1/10 the size. Solid state storage is really crazy- what you can store on a microSD card. Size for size I think it is even a higher density than what my 4TB SSD drive is.
there were petabytes in tape libraries, thousands around the world.I wonder what the total amount of electronic data stored, worldwide, was when you bought your IBM PC? I bet it could not have been more than a few terabytes.
Early 2000's I had an IBM 3494 library with 16x 3590 drives. Library held 3000 or 4000 tapes I think. Each tape at that time was ~50GiB. That library was connected to a bunch of RS/6000s We also had 4x 3490 drives connected to the AS/400. I didn't manage it but one of the other sites had STK Silos. Powderhorns I think.there were petabytes in tape libraries, thousands around the world.
I worked on a giant library "storage silo" machine that held thousands of 3490 cartridges (200MB each). the robot arm would pick, mount, and restack the carts. after the 1989 earthquake, they added bar code reader to the robot arm. all those tapes came loose, what a mess.
That's amazing!! What was stored, financial data? Scientific stuff?Early 2000's I had an IBM 3494 library with 16x 3590 drives. Library held 3000 or 4000 tapes I think. Each tape at that time was ~50GiB.
Don't forget the "Utah Data Center" of 5 Eyes spy data. Everything that happens, everywhere on earth.With all the cheap storage we have in the world today, I wouldn't be surprised if we've surpassed a yottabyte now.
Business in the "Medical Device" part of healthcare so some medical, some scientific but mostly boring business records (testing, manufacturing lot info, etc.) that legally has to be kept "30 years plus the life of the product" Ever wonder how the FDA can order a recall for stuff made decades ago? There's your answer.That's amazing!! What was stored, financial data? Scientific stuff?
The NSA datacenter in Utah is full of the same storage that I deployed today. Extremely fast and dense, but not very cheap. Obviously they have a wee bit more than I do.Don't forget the "Utah Data Center" of 5 Eyes spy data. Everything that happens, everywhere on earth.
Had to look up “yottabyte”. One septillion bytes. Oh my goodness! That is 1 x 10^24 bytes. That’s a lot of bytes.Early 2000's I had an IBM 3494 library with 16x 3590 drives.

Ok, back of envelope... 25Gbps * 220 / 8 = 687.5 GBps;The 36PiB I deployed today has 220x 25Gb/s interfaces for read/write access
What's your hurry?Ok, back of envelope... 25Gbps * 220 / 8 = 687.5 GBps;
36PiB (36*1024^5) would take about 6E13 seconds to read completely. 1.9 million years. Hmmm.
I think your math is slightly off. Your conversion from PiB was to B, not GiB. It should have been 1024^2Ok, back of envelope... 25Gbps * 220 / 8 = 687.5 GBps;

Mine was cassette tape.My 1st data storage device was a 8" floppy diskette
TI 99/4A?Mine was cassette tape.
No. 2650 computer built from Radio Electronics articles.
Oh, duh! Thanks!I think your math is slightly off. Your conversion from PiB was to B, not GiB. It should have been 1024^2
Went on a trip to Quebec in black fly season and had a yottabytes just on me. And that was decades ago.snip

Mine was a tape data recorder for a Radio Shack 32k CoCo connected to the Internet via a 300 baud modem! And it was GLORIOUS!My 1st data storage device was a 8" floppy diskette
I still run WordPerfect. Great program.I ran “Empire: Wargame of the Century” and WordPerfect on this rig.
I still have an old RL01 disk pack. 14" removable. We used to use them on our tram, bus and train control systems here.67 MB RM03 disk drive, cir. 1980. Used with DEC PDP/11 systems... had this funky SMD interface with a bunch of really fat cables. It was about the size (and weight) of a washing machine, with 14" disks that rotated in a pressurized chamber at 10,000 RPM or so.
My first laptop was a Tandy model 100 (I think) which had 3 or 4 lines on the display and could be powered by D batteries.
