And now a 5TB chip???? WOW.
To be clear the 5tb is a drive. The largest microsd cards, like the picture you showed, are currently in the range of 200gb. Which is still amazing at the size of a fingernail.
Btw, those 200gb microsd cards sell for $80, which is also crazy, considering what I remember paying for a 200gb hdd not too long ago.
I used to work on IBM 3350 and 3380 disk systems. Big giant platters. The principle on these giant systems were no different than the floppy or HD systems on PCs. I wrote machine code to manipulate the read/write heads on 3350s to seek data from cyl/trk/sectors in custom database software. Expensive drives, we lost a few of the newer ones at a mainframe site I ran during the 1989 earthquake and were down almost a week when IBM was scrambling to replace many client’s equipment. Solid state stuff is much more resilient and hardy during earthquakes (but not as much fun).
