3.5 inches.
Today, the most commonly used floppy disks are 3.5 inches and have the capacity of 800 KB to 2.8 MB (with a standard of 1.44 MB). The high-density floppy disk drive was first introduced in 1995.

What is the largest size of floppy disk?
The largest size floppy disk is 8 inches. In order: 8 “, 5 1/4”, 3 1/2″ floppy disks. Copied from Wikipedia, used under the act of Fair Use. 8 inch floppies could hold a whopping 110 kB if data!
What is the capacity of a 5.25 floppy disk?
Originally designed as a single-sided, low-density format with a storage capacity of 100 KB, the 5.25-inch floppy disk underwent many enhancements, including the introduction of a double-sided, high-density variant with a capacity of 1.2 MB.
How thick is a 3.5 floppy disk?
The term usually refers to the magnetic medium housed in a rigid plastic cartridge measuring 3.5 inches square and about 2millimeters thick. Also called a “3.5-inch diskette,” it can store up to 1.44 megabytes (MB) of data.
How many bytes is a floppy disk?
The unformatted capacity of 3½-inch double sided high density floppy disk is 2.0 megabytes; in its most common format it has a capacity of 1,474,560 bytes or 1.47 MB (simply dividing by 1,000,000).
How much do floppy disks hold?
Floppy disks store much less data than a CD-ROM disk or USB flash drive. A normal 3½ inch disk can store 1.44 megabytes of data. This is usually enough for simple text documents.
What is the capacity of 8 inch floppy?
Floppy disk technology evolved over time. The first 8-inch floppy disk had a storage capacity of about 80 kilobytes. By 1986, IBM introduced the 3-1/2 inch floppy disk with 1.44 megabytes of storage space.
How much memory can a 3.5 and a 5.25-inch floppy disk hold?
To equal 1 Gigabyte, you would need 1,456 720 KB floppy disks. Image by Greg Shultz for TechRepublic. In the late 80’s, the 5.25-inch floppy disk was on its way out and in 1987 the 3.5-inch floppy disk had moved into the high density category with a capacity of 1.44 MB.
When did 3.5 floppy disks become obsolete?
1990s
The 3.5-inch floppy disk format was the last mass-produced format, replacing 5.25-inch floppies by the mid-1990s. It was more durable than previous floppy formats since the packaging was rigid plastic with a sliding metal shutter. It was eventually made obsolete by CDs and flash drives.
Can Windows 10 read floppy disks?
While 99 percent of users have moved onto solid state drives, USB flash drives, and even CD-ROMs to store their data, Windows 10 can still handle floppy disks.
How can you look at a 3.5 floppy disk and tell if it is a high density or double density disk?
Second, the top-right corner of the back of the floppy has a small hole. If the drive mechanism detects that this hole exists, the computer knows it is a high-density diskette.
Are 3.5 floppy disks still manufactured?
3.5″ floppy drives are still manufactured in the form of external USB floppy drives. Internal drives for desktop and laptop systems are not manufactured anymore, but can be found used/refurbished/new-old-stock.
How big is a Zip drive?
The Zip drive is a data storage device. The company Omega published it in late 1994. Originally it only supported 100 MB disks, but later versions began to support 250 MB and 750 MB disks. Now capacities have reached 1GB and 2GB disks.
How many MB means 1gb?
1024 MB
In this convention, one thousand and twenty-four megabytes (1024 MB) is equal to one gigabyte (1 GB), where 1 GB is 10243 bytes (i.e., 1 GiB).
Who invented the 3.5 inch floppy disk?
Alan Shugart
Invented by IBM engineers led by Alan Shugart, the first disks were designed for loading microcodes into the controller of the Merlin (IBM 3330) disk pack file, a 100 MB storage device. So, in effect, the first floppies were used to fill another type of data storage device.
Do floppy disks have any value?
Such is what’s called “progress” in the computer world. The most interesting thing I discovered in researching this topic is that old floppy discs actually have some value, in large enough quantities. Some large organizations, including the U.S. government, still use floppy disks for data storage.
How much does a floppy disk weigh?
The result: One 3.5-inch floppy disk weighs between 17-22 grams. The average weight of one 3.5-inch floppy disk is 19 grams.

What was before floppy disk?
Cassette Recorder
Even floppy disk drives were rare at the time. When you turned the computer off, you’d lose your data, unless you had something to store it on. The solution that the first PC makers came up with was to use a cassette recorder.
