As the quantity of records that human beings wish to store on their computers grows, greater customers – both at domestic and in commercial enterprise – are seeking to RAID facts structures to do the job. Many specialists believe that RAID systems are the pleasant way to save big amounts of track, photo and video files, and to save you them from being lost inside the event of a difficult disk failure.
In the most effective sense, RAID merely stands for ‘redundant สำรองข้อมูล array of impartial disks’ – or in different phrases, an array of multiple hard drives running together to enhance overall performance or increase secure garage. There are several different varieties of RAID systems, which might be called degrees – regardless of their innate variations. The maximum important systems for the house person are RAID 0, RAID 1, and RAID 5.
RAID 0 structures are designed to growth a laptop’s performance, through the approach of ‘striping’ – breaking up records into fragments and writing it throughout more than one drives. The data throughput is drastically expanded because all 4 drives are accessed in parallel. The disadvantage of this is that although one of the drives fails, the facts may be corrupted or misplaced. RAID records healing professionals can often restore this however it’s far a volatile challenge.
RAID 1 structures are the most not unusual shape of RAID system. It writes facts to more than one disks – known as ‘mirroring’ – and this means that in the event of one disk failing, the records is saved on any other. This makes RAID facts recuperation tons easier, on the grounds that there can be a whole set of facts on the alternative drive. The weakness of this gadget lies with the truth that overall performance is not optimised, inside the way that a striped system would be. It also can be expensive considering, as an example, two 500GB drives are required to get 500GB of facts garage. However, on the subject of protection, this device is paramount.
RAID 5 structures are designed to optimise each overall performance and protection by way of the usage of each kinds of configuration. The gadget stripes the statistics across all of the difficult disks, however does no longer unload all of the parity onto a unmarried power. This prevents a postpone whilst parity statistics is written onto one pressure. With this, one disk can fail and there are no severe effects, because the parity statistics will always be on a extraordinary disk. Again, RAID information recovery is enormously risk-free in the occasion of this happening.
However, there are worries that as hard drives continue to extend in length; the dangers are bound to mount. The extra complicated the device, the greater the probabilities of something going wrong, and the more crucial it’s miles to have access to RAID records restoration specialists.
