No one wants to lose data on their computer, it is to some, liken to a death, literally losing part of your life. Well, fortunate for all computer users around the world, we no longer need to worry about that. There are now many ways to store and back up your data, and an excellent example of this is the RAID hard drive.

RAID? Okay, you might be thinking of the insect spray, but that is not what I am referring to. RAID is the acronym for Redundant Array of Independent Disks. The RAID technology was to make a disk storage system that was reliable and relatively cheap. The RAID hard drive is comprised of several storage disks, but the computer recognizes it as a single hard drive. reading and writing to the disk as it would to a single disk drive.

There are several RAID hard drive types, and I will list a brief description of the most popular two here.

It is important for you to know, that there is a risk to using a RAID 0, because if one hard drive goes out, you will lose the data on the entire RAID 0 array.

Raid 0 is about increasing performance by having 2 hard drives working together as one, and it does this storing half of every piece of data on first hard drive, and the other half on the second hard drive. Thus, higher performance is achieved by each hard drive only having to half the work to load or write a file.

RAID 1 adds redundancy by having every piece of data on one hard drive, mirrored to the other. This way if one hard drive goes out, all the the data is still preserved. The drawback is you only have the storage space of one hard drive rather than 2, whereas with RAID 0, you have the space of the combined hard drives.

RAID 0, you have more hard drive space and higher performance, but a greater risk of failure, whereas, with RAID 1 you have less space but more security. With that in mind, here are a few of the best options of the External RAID Hard Drive.
