An overview of RAID0, which was developed to improve the sequential read and write speed based on individual disks in form of a striped RAID array. Due to the striping (distributing/sharing) of data, the disks are receiving only smaller portions of the overall data flow, so their read/write speed adds up, and so is their total disk capacity. It is important to point out, that RAID0 offers absolutely no redundancy!<br /><br />To show the parallel nature of the data access and the way how data is being distributed via striping, here I use a single byte of information as data. However, real disks deal with 512Byte or 4096 (4kB) chunks, because of their inherent structure (namely, they are backwards compatible with the IBM floppy disks released for the first IBM PC). For this the physical disk is being explained in the context of cylinders, tracks, sectors and gaps.<br />Since RAID0 decreases the mean time between failure, i.e. decreases data security, in industry it is rarely used. Instead, RAID0 arrays are mostly being used for video editing, multimedia applications and gaming setups. In the video also the advantages and disadvantages of RAID0 are being discussed. In addition to RAID0, also the importance of onsite and offsite backup is explained together with disaster recovery.<br />...<br /><a href="https://www.youtube.com/watch?v=nyTJLTKGE-Y" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=nyTJLTKGE-Y</a>
