Its a hard disk at 1956....

The Volume and Size of 5MB memory storage in 1956.

In September 1956 IBM launched the 305 RAMAC,

The first computer with a hard disk drive (HDD).

The HDD weighed over a ton and stored 5MB of data.

Let us start appreciating your 4 GB jump drive

Damn, and I thought my external HD was heavy. Fuck that. But, interesting fact nonetheless.

Haha, insane. You could have alot of fun if you had a timemachine.

WTF. thats fucken odd hey.. but then again.. the data back then that they needed to store would have been of much smaller size.. so it would have been a large drive (storage space wise) for the time.

i wonder how much that would have cost.. lol

The IBM 350 disk system stored 5 million 8-bit (7-bits plus 1 odd parity bit) characters (about 4.8 MB). It had fifty 24-inch diameter disks. Two independent access arms moved up and down to select a disk and in and out to select a recording track, all under servo control. Average time to locate a single record was 600 milliseconds. Several improved models were added in the 1950s. The IBM RAMAC 305 system with 350 disk storage leased for $3,200 per month in 1957 dollars, equivalent to a purchase price of about $160,000.
