It is much easier to build hard drives with lots of memory than Ram with lots of memory. You need some RAM though because it can be read from and written too much faster than hard disks.
Hard drives, removable disks, and CDs are ways of storing information for computers. They make the process of backup up or moving data from a computer much easier.
a lot.
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.
how much did a 250 MB hard drive cost in 1988
4.470000000000001
2 million for just the building the tower was an additional cost
$48 (additional $10 to retake written test; additional $20 to retake driving test)
Enterprise class disks generally spin faster (over 15,000 RPM), have higher capacities, and are much more expensive.
Tape Storage.
A Zip disk was a brand of removable (and reusable) storage. They came in two varieties; the original Zip disks held 100 MB and the second generation held 250 MB. A Zip drive was a piece of hardware designed for reading these disks. The original drives could only take the 100 MB disks, later ones could take either the 100 or 250 MB disks. You don't see them much anymore, because even 250 MB is peanuts. A drive cost $100 or more, and the disks were several dollars each ... you can buy a USB "thumb drive" that holds as much as several Zip disks for less than the cost of a single Zip disk, and that's ignoring the cost of the drive to read them. So: very definitely hardware, not software, though you did have to have the proper drivers (software) for the drive to get it to work.
