In this section, we have our full range of RAID External Hard Drives. RAID is a acronym, which stands for Redundant Array of Inexpensive Disks. This was a computer system which was developed so that a large number of low cost hard drives can be linked together to create a single capacity storage device. 

The result of RAID was better performance, storage capacity and also reliability compared to other solutions. It has been widely used and deployed method for storage in the enterprise and server markets, yet over the few years has become more common in the consumer market. It also offer a much more secure way to store your data, as depending upon you setup you can make copies of the hard drive using a mirroring technique. If you want to know more about different RAID setups, scroll down to the bottom of this page.

RAID 0 utilizes a technique known as striping. Striping uses a one piece of data such as a graphic image, and advances that data throughout multiple hard drives. The benefit which striping has is due to enhanced overall performance. Double the quantity of data may be written in a certain time period to the two drives in comparison to that exact same data getting written with a solitary hard drive.

RAID version 1 was the very first genuine execution of RAID. It possesses a simple type of redundancy for data via a method referred to as mirroring. This type usually needs 2 individual hard drives of comparable capability. One hard drive will be the active hard drive plus the supplementary hard drive will be the mirror. Whenever information is written on the active hard drive, the identical information is written on the mirror hard drive.

RAID 0+1 is a hybrid kind of RAID which a number of suppliers have put in place to try to provide the benefits of each one of the 2 variants put together. This typically only works over a system having a minimum of four hard drives. After that it offers the techniques of mirroring as well as striping to supply the overall performance and also redundancy. The initial pair of hard drives will probably be active and also have the data striped across these as the second pair of hard drives is a mirror of this data from the first two in the unit.

RAID 10 is actually effectively an identical variation of RAID 0+1. Instead of striping data between your hard drive sets then mirroring these, the initial two hard drives in a set are then mirrored with each other. The 2nd two hard drives form another pair of hard disk drives which is the mirror of each other yet keep striped data with the initial set. It is a type of nested RAID set up. Hard drives 1 and 2 is a RAID 1 mirror and drives 3 and 4 will also be a mirror. Both of these sets will be then set up as stripped array.

RAID 5 is most effective type of RAID that may be present in a desktop computer structure. Generally it takes the form of a hardware controller to handle this array, however, many desktop operating systems can create this using software program. This process utilizes a form of striping along with equality to keep data redundancy. No less than 3 hard drives is needed to create a RAID 5 array and so they needs to be identical hard drives to find the best overall performance from this setup.
