File size is a measure of how much data a computer file contains or how much storage space it is allocated. Typically, file size is expressed in units based on byte. A large value is often expressed with a metric prefix (as in megabyte and gigabyte) or a binary prefix (as in mebibyte and gibibyte). [1]
A cluster is the smallest logical amount of disk space that can be allocated to hold a file. Storing small files on a filesystem with large clusters will therefore waste disk space; such wasted disk space is called slack space. For cluster sizes which are small versus the average file size, the wasted space per file will be statistically about ...
Density is a measure of the quantity of information bits that can be stored on a given physical space of a computer storage medium. There are three types of density: length ( linear density ) of track , area of the surface ( areal density ), or in a given volume ( volumetric density ).
The usable capacity of a RAID 01 array is the same as in a RAID 1 array made of the same drives, in which one half of the drives is used to mirror the other half. ( N / 2 ) ⋅ S m i n {\displaystyle (N/2)\cdot S_{\mathrm {min} }} , where N {\displaystyle N} is the total number of drives and S m i n {\displaystyle S_{\mathrm {min} }} is the ...
The fundamental components of a general-purpose computer are arithmetic and logic unit, control circuitry, storage space, and input/output devices. Technology and capacity as in common home computers around 2005. Generally, the lower a storage is in the hierarchy, the lesser its bandwidth and the greater its access latency is from the CPU. This ...
As far as cloud storage goes, TeraBox offers the most free storage for photos or videos, with 1TB of space. This is enough to store 400,000 photos or 51,200 one-minute videos, according to the ...
The capacity of a hard disk drive, as reported by an operating system to the end user, is smaller than the amount stated by the manufacturer for several reasons, e.g. the operating system using some space, use of some space for data redundancy, space use for file system structures.
