That makes for 7800x the capacity of early 128MB microSD cards. 7800x improvement with the same physical media. 3.5" Floppy disks, on the other hand, went from 1.44MB to 2.88, but no one used 2.88. CD-sized disks went from ~650MB (CD) to around 100GB (3-layer ultra HD Blu-ray), just a 153x improvement, and CDs were released in the early 80's!
To be fair, 3.5" floppy discs were introduced at 400kb, ended at 2.88MB which is about a 720% capacity increase. Still not stunning but not as bad as a simple doubling.
That's a terrible comparison for floppy drives. They started out at 80KB in the early '70s and ended up at the 240MB LS-240 drive, or even higher if you consider ZIP disks a type of floppy.
3.5" disks started at 80KB in the early 70's? You should edit Wikipedia and give the right citation. The article starts with "In 1981, Sony introduced their 3 1⁄2-inch floppy disk cartridge (90.0 mm × 94.0 mm) having a single sided unformatted capacity of 218.8 KB and a formatted capacity of 161.2 KB." It also references '76 as the time when 5.25" disks were discussed. If you have other information, I'd like to see that. Or maybe you were talking about plastic diskettes with magnetic discs inside them in general? If that is the case and especially if you want to include ZIP disks, we might as well throw EEPROMs into the mix. Which would trounce everything again. :D
Just to think I remember the day in the pub when a nerd pulled out a 256MB full size SD card for their digital camera, and I was amazed at the capacity, and the small size, and how that compared to my first 3.5" HDD about a decade before.

3D does it for you. Imagine a stack of 96 Blue-ray disks. :)Reflex - Tuesday, February 26, 2019 - link

https://en.wikipedia.org/wiki/List_of_floppy_disk_...Looks like wiki was already correct.
My 1st experience with floppy disks was the DEC 01 at 250KB. God that was so long ago.

I was quite happy with a 50MB HDD for my Amiga...plb4333 - Tuesday, February 26, 2019 - link
I was happy with a 400KB floppy and a 'Casette Tape Player' for my Commodore 16. LOL! What a change there's been...jjj - Tuesday, February 26, 2019 - link
WD/Toshiba's 1.33Tb die should be 158.4mm2 so you can't quite fit it in a microSD.mkozakewich - Tuesday, February 26, 2019 - link
In a year or two, we'll reach the 2TB limit of SDXC! I wonder when they'll release the next spec?GTRagnarok - Tuesday, February 26, 2019 - link
They already did. SDUC.spaceship9876 - Tuesday, February 26, 2019 - link
The bigger news is that the SD association announced micro sd express cards yesterday.Xajel - Thursday, February 28, 2019 - link
UHS-I ? nope, we want microSD Express now.supriyadn - Wednesday, June 12, 2019 - link
Very beneficial article. Also, I get some very useful information about top ten budget-friendly MicroSD card on dealnews.in.
