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.

Worry free backup
This is a really useful piece of kit, with 2 x 1tb of external hard drives, either use independently, or mirror together, giving extra security. It is easy to swap an internal hard drive via simple catch. It starts and shuts down with PC, gives visual feedback of its working, and so easy to install.
Amazing
I am completely delighted with WD! For two months it has been working perfectly and smoothly under Leopard and Snow Leopard (you just plug the device, install the WD Device Firmware, configure Time Machine and you are done!). A MUST have if you want massive storage or an excellent backup drive that above everything is reliable and quiet. The only "thing" may be the light that may disturb you at night (I have it in my bedroom) but that is not even a problem (you can always put something over the light). I repeat, a MUST have. Congratulations WD!
Compact and quiet
I have just had it for a couple of days now. I am using it in RAID 1 mode. It seems to be quiet and its all fine now . The USB cable seems to slip out of its socket quite easily which is not a worry unless you keep moving it once its set up. The Setup program installed some additional trial-ware even though it was not selected for install. other than that i am happy with it.
