WHICH DISK DRIVE DO I NEED?
The choice of disk drive which is best for you depends upon your data storage needs. With a smaller
capacity disk drive, you will have to change disks more often than with a larger capacity drive. If you
envision needing storage for small blocks of data at a time (short letters/reports or programs), you might
find the small capacity disk convenient.
If you have large blocks of data to store (either one large block, or many related small blocks), the need to
change disks to access various portions of the data soon becomes inconvenient. Medium to high capacity
disks will be more practical.
For the case where numerous users are sharing the same machine, medium sized disks allow the
convenience of moderate data storage capacity while letting each person keep track of his own disks.
If you are handling very large amounts of data, want FAST access, or would just like the convenience of not
having to find the proper disk for each application, the rigid disk will allow you to store vast amounts of
information, and access any of it without having to find and insert another disk.
Compare your projected usage with the chart below to determine your disk drive needs. Hint: You might as
well double your usage figure, you'll find twice as many uses for your 820-11 as you had thought.
