The capacity of flash drives is increasing all the time. 4, 8, 16 and 32 Gb are common and very cheap.
128 Gb drives are available.
USB flash drives hold large amounts of information due to the advances in silicon technology. The storage inside the flash drive is very small and dense. This allows the manufacturer to build a small flash drive that can store gigabytes of data.
MFM is modified frequency modulation and it works on floppy discs to encode the data. It is now becoming an obsolete system since DVDs and flash drives hold so much more data.
Zip,Super Disk, and Jaz drives hold large amounts of data and are portable.Floppy Disk and hard drives and notportableand cant hold that much data.
There are thin fibers in the middle of every flash drive that help to secure all of the data. The strength of the fibers determines how much data you can hold.
Not all flash drives are the same. Some will hold as low as 512MB while a few will hold as much as 128000MB (128GB). The most common amount of capacity (now days) for a flash drive is 1000MB (1GB).

A CD is useful if you are going to play music in an older stereo or car. Most will have a CD player. Some newer CD players will play CD's with MP3 compressed audio, extending the play time by as much as 90%. A flash drive is useful if you want to hold more music (most flash drives hold much more than 1 Gigabyte (1024MB) of info, CD's top out at 800MB. Flash drives can also hold any type of compressed audio or higher-than-CD quality audio (higher than 16 bit, 44.1kHz). Flash drives also have no moving parts, and are not as susceptible to extreme temperatures, scratching or moisture.
USB sticks vary in data storage from 2GB to 32GB. Many external hard drives are 250GB, 500GB or 1TB, and are often more cost-effective.
Digital Versatile Disks (DVD) will store that much as will thumb drives/ memory sticks/ USB drives
floppy drives arn't stable enough, they don't hold much data and can be completely ruined if you drop them. whereas harddrives can hold up to 200x data a floppy disk can. although they can break if you drop them,they have a better chance of another useage. buy a portable harddrive. that way, you can take it wherever you go.
Every flash drive can hold 10 kilobytes. In fact they can hold much more than 10 kilobyte. It is likely that during original development and testing there may have been some with a 10 kilobyte capacity but those first available commercially were in the multiple megabyte range.
A flash drive can hold anywhere from 256 MB to 8 GB.
