If you're a corporate executive or work in medium-to-large business, you may use a raid data server for data storage. But you may never think twice about how it works. When it crashes, though, you know there's trouble. And, as reliable (after all, RAID stands for Redundant Array of Independent Disks) as they are, there's a lot that can go wrong with these complicated devices.

 Let's take a look at how a raid server works.

 A raid array is designed to:

- protect your data against loss with an added level of duplication

- provide higher input/output speeds

In some cases, a raid array also provides additional storage capacity. Since this set-up does not offer data redundancy, though, you lose the benefits of added data storage reliability typical with many raid servers.

 A raid server distributes data across an array of disks, duplicating that data on each disk (except in the case of a Raid 0 server). If one disk or hard drive goes bad or becomes corrupt, a professional RAID data recovery service can swap out the disk and your data is protected on the other disks in the array.

 In a Raid 1 data server, the data is duplicated across multiple disks (at least two, but it can include more). Your raid data server will continue to function as long as at least one disk in a mirrored pair is still functional.

 The more disks you have in a raid 1 server, the less chance you have of losing your data. 24 Hour Data recommends this form of raid array. If your server should fail, rely on professionals in RAID Data Recovery to replace a drive, recover your data, or repair your server.
