What is RAID. ?. RAID is an acronym for Redundant Array of Independent Drives (or Disks), also known as Redundant Array of Inexpensive Drives (or Disks). The various types of RAID are data storage schemes that divide and/or replicate data among multiple hard drives. Case Study: Facebook f4. Steve Ko. Computer Sciences and Engineering.

Parallelism improves performance. Plus extra disk(s) for redundant data storage. Provides fault tolerant storage system. Especially if failed disks can be “hot swapped”. media. PM Video 10:28. Selecting a Hard Drive. Some considerations when selecting a hard drive:. Drive capacity. Today’s hard drives range from 60 GB – 10 TB. Spindle speed (measured in RPM). Common spindle speeds are: 3600, 5400, 7200, 10,000, and 15,000 RPM.
