IBM FBA (Fixe4d Block Architecture) 3310/3370 pre-formatted at 512 bytes/block.
Records in files were written according to record-size, etc.

Sound familiar? Kind of like PC HDD's? Think Original IBM PC's...

BWAHAHAH!

Well, thanks guys. But the point (if there really is one) is the correlation between the Fixed Blocks of 512 bytes of the said Mainframe drives and the original (and up to now) HDD's used in PC's and how they "shrank"...

And I really don't care who knows my age. We old duffers should be pleased we made it this far and still have much to offer.

Cheers!

(thanks for that great clip...)

I saw some 3380 drives where i studied. I always wondered at what size (physical and capacity) the hard drive would get. Now you could put the entire data of stored on twenty of those that took a room in a single micro sd.

Well, just to keep things in the correct perspective, the 4004, Intel's very first (4-bit) processor, had as much computing power as the ENIAC did. :yes:
