Redundant Array of What Disks?!
We are thankful to have discerning readers looking at our blog posts, and one of these readers commented on a recent post we did about RAID setups. In this article, we discussed how RAID stands for Redundant Array of Independent Disks. This is true, though originally the acronym stood for Redundant Array of Inexpensive Disks, as our reader pointed out. More often now the “I” stands for “Independent”.
Either acronym can be misleading depending on the setup. Some RAID setups can use quality (read: not inexpensive) disks, and some RAIDs are actually set up so the multiple disks require each other to function, meaning they are not completely independent. For example, in a RAID 0 setup the data is split between disks, making it not entirely redundant (or independent for that matter). These setups are used more for performance, while setups like RAID 1 have mirror images on each disk, so they are actually redundant but perform slower.
So what does RAID stand for? Redundant Array of Independent Disks? Redundant Array of Inexpensive Disks? Well, it doesn’t really matter. Different RAID setups can be fitting for different people’s needs. If you work in an environment where data loss is not an option, it is worthwhile to create more redundancy and sacrifice performance speed. If you are looking for storage and speed, it’s possible you can use a more performance speed based system.
You’ll want to do your homework before putting any type of RAID system together, but you can give us a call here at DriveFish and we will be glad to answer any questions you may have and help you construct a custom RAID setup suited to your needs.
