But it does allow you to spread large files such as video projects and backup archives across multiple disks. A concatenated disk set provides no swifter access to your data, and it offers no additional data protection. In this case, the operating system simply combines the storage capacity of all the drives in the set, to create what appears to the operating system to be a single volume. Rather, it’s another way of treating multiple hard disks as a single volume. The other option Disk Utility offers in its RAID pane-Concatenated Disk Set-is technically not a RAID. The downside of a striped RAID is that because files are spread out among the drives, you lose all your data if one of them goes south. The advantage of a striped RAID is that it provides better read and write times, particularly if you’re working with large files-video and audio files, for example. And in some cases, a mirrored RAID can provide better read times.Ī striped RAID splits your data among the drives-parts A, B, and C of a file could go on one drive while parts D, E, and F go on another, for example. It helps protect your data by writing it to two drives rather than to one-so if one drive fails, you still have all your data on the other. Each drive holds the same data one mirrors the contents of the other. Whether the RAID shares or duplicates data is determined by itsĭisk Utility supports two RAID levels-Mirrored RAID Set (RAID Level 1) and Striped RAID Set (RAID Level 0)-as well as something called a Concatenated Disk Set (also known as JBOD, or Just a Bunch of Disks).Īt its most basic, a mirrored RAID is composed of two hard drives. ![]()
