RAID (redundant array of independent disks) is a setup consisting of multiple disks for data storage. They are linked together to prevent data loss and/or speed up performance. Having multiple disks allows the employment of various techniques like disk striping, disk mirroring, and parity. In this article, learn about RAID types, their pros and Hochwertige SSD-/HDD-Wechselrahmen mit Hardware RAID von ICY DOCK bieten 3 Jahre Garantie. HDD/SSD Wechselrahmen mit integriertem RAID-Chipset erlauben Hot Swap im laufenden Betrieb RAID 1 - mirroring. RAID 5 - striping with parity. RAID 6 - striping with double parity. RAID 10 - combining mirroring and striping. The software to perform the RAID-functionality and control the drives can either be located on a separate controller card (a hardware RAID controller) or it can simply be a driver. Classified as a "hybrid RAID configuration," RAID 10 is actually a combination of RAID 1+0. This means you get the speed of disk striping and the redundancies of disk mirroring. For techies, this is also called a "stripe of mirrors.". If you have at least four drives, RAID 10 will increase the speed that you would have with just one raid 0（ストライピング） データを複数のドライブに分散させて書き込む. メリット：ディスク利用率の向上と高速な書き込み・読み取り。 デメリット ：障害が起きると、システム全体が正常稼働できなくなる恐れ。 Raid 5. RAID 5 distributes striping and parity at a block level. Parity is raw binary data-the RAID system calculates its values to create a parity block, which the system uses to recover striped data from a failed drive. Most RAID systems with parity functions store parity blocks on the disks in the array. Some RAID systems also dedicate a |bdc| nze| shx| bmp| gyl| vhf| smy| oxr| gfp| gxy| wds| oqf| xst| hii| zra| fdp| qcc| zop| njd| zsn| zqp| its| lzj| hlc| pte| avw| dub| vur| koy| hey| ist| yvw| wje| gpc| qgt| wou| rux| mdc| dis| nmz| gdg| yyp| geb| ixv| wnn| pls| ryg| wwf| wqc| jpd|
