Double-density disks stored 720 kilobytes of data while high-density disks stored 1.44 megabytes. Floppy disks and their associated drives were gradually replaced in many personal computers by hard disk drives, also pioneered by Alan Shugart and manufactured by Seagate Technology. Early hard drives could store up to 5 megabytes of data after formatting. Similar in concept to floppy disks, hard disk drives stored data on a rigid platter connected to the computer by a data cable. Hard disks were used primarily for storage and easy access, not for moving data from computer to computer. For portability, floppy disks were eventually replaced by recordable compact discs (CDs) and digital video discs (DVDs) as well as flash drives.
