External RAID drives
RAID
— RAID arrays implemented as separate devices (usually external, see "Execution"). Such a device consists of several hard drives installed in one housing and combined into an array, perceived by the system as a single drive. There are several types (levels) of RAID, which differ in the way disks interact in an array and, accordingly, in the specifics of their application. So, in RAID 0, information is alternately written to each disk, which increases the speed of work; in RAID 1, each disk is a copy of all the others, which gives maximum fault tolerance, etc. Detailed information on RAID levels can be found in special sources. Also note here that buying a RAID array may turn out to be more convenient than assembling it from separately purchased disks: a ready-made array is initially equipped with everything you need and requires only minimal configuration. The main thing is to clarify before buying which RAID levels the selected model supports.| clear | Save List |
