Input interpretation:

RAID


Equation:

T = n F D |   |  \nT | total RAID capacity\nn | number of drives\nD | drive size\nF | storage factor


Input values:

RAID level | RAID1\nnumber of drives | 2\ndrive size | 500 GB  (gigabytes)


Results:

total RAID capacity | 500 GB  (gigabytes)\n= 0.5 TB  (terabytes)\n= 5×10^11 bytes\nbase-2 RAID capacity | 465.7 GiB  (gibibytes)


Parameters:

storage efficiency | 50% or 1\/2\nminimum number of drives | 2  (drives)\nmaximum fault tolerance | 1  (drives)\ntheoretical read performance | 2 ×\ntheoretical write performance | 1 ×


Minimum configuration:
