| RAID 1 Arrays Data Recovery |
Data Recovery from RAID 1 ArraysA RAID 1 array consists of two drives, the data on drive 1 is an exact copy of the data on drive 0. There may be other 'Hot Spare' drives installed in the array so that, should one drive fail, it will be automatically replaced by the spare and the array rebuilt. Because there is some redundancy, then should a single drive fail, then either hot spare will kick in or there will at least be a copy of the data on the remaining drive. however, backup your data on a regular basis and keep the backups in a safe place. Redundancy RAID systems are not a substitute for backing up. 
Advantages and disadvantages of RAID 1Because there are two drives in a RAID 1 array, writes take twice as long as a standalone drive, however, some RAID card manufacturers have utilises multi-drive-reads which improves the speed of reads. It does this in a similar fashion as RAID 0, simultaneously reading the first block from drive 0 and the next block from drive 1. Where multi drive reads are not utilised, reads take the same time as a standalone drive Uses for RAID 1One of the most common uses of RAID 1 is to install the Operating System on it. Because there are relatively few writes to the disks, using RAID 1 will mean that the system will still run should a single drive FAIL which could mean the difference between a server going down or remaining online. |
