What is RAID in Mac disk Utility?
You can create a Redundant Array of Independent Disks (RAID) set to optimize storage performance and increase reliability in case of a disk failure. When you create a mirrored RAID set, your data is written to multiple disks so the information is stored redundantly.

What is a concatenated stripe in Linux?
A concatenated stripe is simply a stripe that has been expanded from its original configuration by adding additional components. RAID 0 volumes allow you to quickly and simply expand disk storage capacity. The drawback is that these volumes do not provide any data redundancy, unlike RAID 1 or RAID 5 volumes.
What is a RAID 0 volume?
RAID 0 volumes, including both stripes and concatenations, are composed of slices or soft partitions and enable you to expand disk storage capacity. They can be used either directly or as the building blocks for RAID 1 (mirror) volumes, transactional volumes, and soft partitions. There are three kinds of RAID 0 volumes: Striped volumes (or stripes)
What is a concatenated volume in Linux?
A concatenated volume, or concatenation, is a volume whose data is organized serially and adjacently across components, forming one logical storage unit. Use a concatenation to get more storage capacity by combining the capacities of several components.
