How to make RAID from USB drives
RAID stands for redundant array of inexpensive disks. It combines multiple disk units into a logical unit. If you make a RAID with two 128GB USB flash drives, it will appear as a single 256GB drive. In theory, if you had a single program that requires 256GB, you would have enough space using RAIDs from two USB drives, whereas if you used two separate disks and did not merge them into a logical unit, you would be limited to 128GB.
Are RAIDs still Necessary or Efficient?
Cloud Backup vs. RAID
If you have to reformat your hard drive or move some large files from your laptop, you can backup the files on a RAID array, whether you made them from USB drives or not. However, hard drives have an average life of 3-4 years, so expect your drives to fail occasionally. If you have a RAID 1 array as a backup system, even if one drive fails, you can buy two new drives and copy the files. You could also end up with a scenario that the other drive could also fail before you copy the files to two new drives. This used to be the case for a long time causing additional risk and lots of cost at unexpected times; however cloud backup now offers a new option for individuals and small and large businesses for backup. RAID’s backup function could be replaced by cloud backup and you can scale up or down based on your needs. If you choose a credible cloud backup provider such as Genie Backup Manager Pro to replace your RAID, you will easily keep your files safe for years to come.
