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. Hai. Lu. RAID.

Magnetic disk doubled capacity and halved in price every 3 years. Use multiple smaller disks (c.f. one large disk). 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. In an increasingly competitive market Communication Service Providers CSPs are being forced to quickly adapt to meet customer expectations and market trends by di31erentiating themselves from competit Questions to consider during this lesson:. - How is digital evolution similar to biological evolution? How is it different?. - How can the principles of natural selection be applied to solve engineering design problems?.
