Supercomputers do not usually use any type of floppy disk, they usually use custom made high data rate hard disks and tape drives.
Modern supercomputers would typically use a RAID system of multiple disks providing a high reliability high data rate facility that looked to the computer's OS like a single drive with a capacity of several petabytes (or possibly exabytes by the time you read this).
The floppy disk which is commonly referred to as a high density floppy disk is a 3.5 inch disk. It has a storage capacity of 1.44 MB.
supercomputer is probably what you are looking for.
Floppy drive was the first storage with portable data storage capacity.. However the data storing capacity of floppy drive is not enough but in early days it helped a lot..
1.44MB
Zip drive, floppy capacity is usually only ~1.4GB
The maximum storage capacity of a floppy disk that uses the 64kb keyword is 64 kilobytes.

In old machines floppy drives were primarily used for booting up the machine. Floppy drive has a very small memory capacity. Almost all of the latest Operating Systems are larger than a Floppy drive capacity of e.g. 1.44MB. Floppy's are not as reliable as other media and can easily get corrupted.
