While often thought of as a storage solution for businesses, RAID can provide several benefits for the home user.

RAID can be set up in a number of ways, each offering something different, and some combining two or more benefits into one. While a standard hard drive or solid-state drive might do you just fine, you should consider upgrading to RAID.

Redundant Array of Independent Disks, or RAID, is a way of combining multiple drives together for improved performance, capacity, redundancy, or a combination. While in the past RAID required expensive hardware beyond the budget of a home user, nowadays most modern computers and laptops are capable of supporting RAID. This can either be through software i.e. built into your operating system, or hardware, with a controller built into a RAID unit. So what kind of RAID setup would a home user require? There are a multitude of RAID levels, all offering improvements on a standard hard disk drive. However, for home users, RAID 0 and RAID 1 are probably the best solutions; both are easy to set up, and both offer different benefits. What's more, they can be combined to form RAID 10, sometimes referred to as RAID 0 + 1.

RAID 0, also known as striping, is RAID in its purest form, and turns two or more hard drives into a single storage unit, providing increased capacity and performance. RAID 0 is, in essence, the sum of its parts; you have multiple platters to store data, and multiple read/write heads in operation. For example, if you set up two 2TB hard drives as a RAID 0 system, you'll have a 4TB storage unit that is twice as fast. However, due to data being striped (or spread) across both/all disks in the array, if one drive fails, the data is lost. The failed drive will then have to be repaired by a RAID recovery specialist. RAID 0 would suit home users who want lots of storage space and fast read/write speeds, but remember to regularly backup your data.

RAID 1, or mirroring, provides increased read speeds, but doesn't provide additional capacity. This is because data is mirrored across the drives in the array, meaning if one fails, there will be another copy on hand. Because multiple heads are working in tandem, read speeds are faster; write speeds, on the other hand, are slower, as data has to be written multiple times. Additionally, you only have 50% of the total storage space of the drives; for example, a RAID 1 array with two 2TB drives only has a storage capacity of 2TB. RAID 1 is a better solution for home users who are less concerned about having lots of storage space, but want an extra copy of their data for peace of mind. However, backing up is still essential, as multiple drives in the same array could fail, especially if they are from the same batch.

For home users who want the benefits of both RAID 0 and RAID 1, there is solution - RAID 10. RAID 10 requires at least four drives, and data is striped and mirrored across two pairs, offering more capacity, faster speeds, and protection against data loss. There are of course a multitude of RAID levels, and RAID 0 and RAID 1 aren't the only solutions for home users.
