RAID is an acronym for Redundant Array of Independent Disks. With RAID enabled on a storage system you can connect two or more drives in the system so they act as one large volume fast drive or set them up as one system drive used to automatically and instantaneously duplicate (or mirror) your data for real-time backup.
Which RAID mode should I use?
Speed (RAID 0)
Set in high-performance mode (also called striped mode or RAID 0) the storage system gives you the power you need when you're:
- Designing huge graphics and need a lightning-fast Photoshop scratch space.
- Editing DV or HD video and want a smooth work flow with no dropped frames.
- Rendering complex 3D objects or special effects.
- Driven to be the first geek on your block with a computer so fast it blows your socks off.
Data protection (RAID 1)
Set the system to data protection mode (also known as mirrored mode or RAID 1) and the capacity is divided in half. Half of the capacity is used to store your data and half is used for a duplicate copy. If one drive goes down your data is protected because it's duplicated.
