Yes in fact most do. While there is new SSD(solid state drive) technology, standard hard drives still have disks. An SSD is extremely fast and efficient but more expensive.
A standard 3.5-inch floppy disk has a capacity of 1.44 megabytes. To convert 1 terabyte (1,000,000 megabytes) to floppy disks, you would divide 1,000,000 by 1.44, which equals approximately 694,444 floppy disks. Therefore, it would take around 694,444 3.5 floppy disks to equal 1 terabyte of data.
It is a standard CD driver, for use with DOS and other low level boot disks, Google it for more information.
No. A standard DVD disk does not have the capacity to record a movie in BluRay format.
The best format is Blu-Ray DVD disks, but the most common disk is a standard DVD disk.
They are different sizes, but 3.5" and 5.25" were fairly standard. They even had huge 8 inch drives on some machines.
That would depend on what you mean by "standard." All drives made in last 20 years or so have supported HD (1.44 MB) disks.
The diameters of the disks can vary widely depending on their intended use. For example, standard compact discs (CDs) have a diameter of 12 cm, while DVDs are also typically 12 cm. Hard drive disks can range from 2.5 inches (about 6.35 cm) for laptop drives to 3.5 inches (about 8.89 cm) for desktop drives. Other specialized disks, like those used in certain scientific applications, may have different dimensions.
