Which disk can store more data?
High-density floppy disks, while sharing a 3.5-in size with the standard floppy disks, are much faster and have up to one hundred times more capacity than the standard floppy disks. One example is the Zip drive, produced by Iomega. Each Zip disk is capable of storing up to 100 MB of data.
What device can store data?
The term backing storage refers to any non-volatile data storage that will retain a computer’s data even after the computer is powered off. Common types of backing storage devices are hard drives, SSD, external hard disk drives, optical media such as CD or DVD, and flash media such as thumbdrives and memory sticks.
Which storage device can store the least data?
Computers need a floppy drive to read floppy disks, and many modern computers are no longer supplied with a floppy disk drive because we now work with much larger files. Now we are capable of storing at least 16 GB of data on a memory card which is, physically, six times smaller than a floppy disk.
How is data stored on a floppy?
How does a floppy disk store data? A floppy disk is a magnetic media and stores and reads data on the floppy disk using a read head. When a 3.5″ floppy diskette is inserted into the drive, the metal slide door is opened and exposes the magnetic disk in the floppy diskette.
Who holds a large amount of data than floppy disk?
A Zip disk is similar in size to a floppy diskette, but thicker. It is basically a “super floppy” but the higher construction tolerances and smaller read/write heads allow the Zip disk to hold more data than a floppy. The first Zip disks held 100 MB.
How big of a disc can I store on my computer?

DVDs have single and double-sided versions, and for example, a double-sided, double-layer DVD can hold 17.08 GB of data. That means 17080 MB in decimal and 17489.92 MB in binary bases.
What kind of storage does a computer have?
