It's amazing that ... ( 1 year ago by JDonahue79)
It's amazing that in just 50 years, it went from 5 megs of space that was the size of a kitchen room to a 1 terabyte hard drive that's the size of a small purse. There's also word that by the year 2025, hard drives may hit the pedabyte mark.

RAMAC RAMAC. RAMAC. I can't stop saying it! RAMAC!
Actually this thing is pretty significant. First time data storage went 'online'. Begining of the end for punchcards (though that would take another 25 years!)
RAMAC!

its more like 5-6 years, and even then most likely we wont even be using "read/write" hard drives, but solid state drives much like large flash drives. By 2025, computers wont even use transistors, but instead might use photons (charged light particles)to process operations.

Did anyone else catch the "compact" part... its the size of a shed so i guess its compact.

Whats amazing is just ten years later they made a computer the size of a bread box for Gemini.
Wow! what a beast, ... ( 2 months ago by cpmisalive)
Wow! what a beast, I guess it uses only one side of the disc. The price must have been astronomical, the maintenance contract, eye watering. 600ms access time for the RAMAC vs. 6ms for a decent modern drive (100x faster) Modern drivs 6ms vs. 6
µs for SSDs (1,000x faster) Modern hard disc drives have reached a plateau of performance, Flash memory will replace them in the very near future, my XPS has two 512GB SSDs and its like lightning.

Back then 5 MHz was very very fast!

As a girl, I'd go on one Saturday a month with my father where he worked on these machines. Lots of noise in a big warm room with fans, elevated floors containing miles of wire that he sometimes needed to replace and rework. It was neat-o. I would rollerskate on those floors.

Holy krap!
Has anyone ever had seen the size of those HDDs?
Plus, if you've programmed those mainframes with punch cards back then, it must've been hell to wait to see your syntax errors come out the compiler after a hour long wait.
I'll never complain about a slow C++ compiler again.

but still, SSD's produce great heat... it'll take some time before they develop a real HDD replacement
