That was the Model 350 disk drive for the 305 RAMAC system. Its capacity was 3.75 megabytes with a 1-second average access time.
Interesting history in Wikipedia:
"The IBM 350 drive had fifty 24-inch (0.6 m) platters, with a total capacity of five million 6-bit characters (3.75 megabytes).[9] A single head assembly having two heads was used for access to all the platters, yielding an average access time of just under 1 second."
