RAID is a high-tech acronym for Redundant Array of Independent Disks. The acronym is not important. What is important is that the inclusion of RAID technology in WD's dual-drive external storage systems make them very powerful storage products.
With RAID enabled on a storage system you can connect two or more drives in the system so that they act like one big fast drive or set them up so that one drive in the system is used to automatically and instantaneously duplicate (or mirror) your data for real-time backup.
There are two reasons you might want a RAID system of drives.
1. You need tons of storage space and you need it to be fast. (RAID 0)
2. You want to instantaneously and automatically backup your data. (RAID 1)
Which RAID mode should I use?
 RAID Mode Comparison |
1. 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 you need a lightning-fast Photoshop scratch space.
- Recording large DV files while maintaining clean audio performance.
- Editing DV or HD video and you want a smooth work flow with no dropped frames.
- Rendering complex 3D objects or special effects.
- Performing disk-intensive database operations.
- Driven to be the first geek on your block with a computer so fast it blows your socks off.
Why is RAID 0 so fast?
It's a bit complicated, but suffice it to say that two heads, or in this case, drives, are better than one. Picture two hoses filling a bucket at the same time or two men bailing a boat and you can understand why two drives striped are faster than one. Data is saved (striped) across both drives and accessed in parallel by both drives so you get higher data transfer rates on large data accesses and higher input/output rates on small data accesses.
2. Data protection (RAID 1)
Set the system to data protection mode (also know as mirrored mode or RAID 1) and the data is duplicated onto one of the drives providing two copies of all the data. This reduces your capacity to the size of a single disk.
So why do I want that kind of redundancy?
It's your data, your family pictures, your movie of baby's first steps, your first novel. Is it important? You decide. If it is, then RAID mirroring if for you.
