Upgrade your data resiliency with RAID 1
The sound of a dying hard drive can be terrifying. It means a headache, downtime, and replacement costs in the best case. In the worst case, it means sending the drive to a data rescue lab. Using a redundant array of independent disks with mirroring (RAID 1), you can make a drive failure less of a nightmare.
RAID 1 is one of several RAID „levels,“ and is the polar opposite of it’s speedier cousin, RAID 0 . Where RAID 0 stripes data across drives to attain higher read and write performance, RAID 1 writes the same data across all the drives in the array. Using RAID 1, the chances of losing data to a drive failure is one divided by the number of drives in the array. In comparison, those chances are multiplied in RAID 0.
If you’re thinking that RAID 1 is a lazy man’s backup, think again. RAID 1 is not a backup, and is never, ever a replacement for a good backup. Always remember that RAID 1 is a hedge against hardware failures, not malware…
