RAID LEVELS

RAID.EDU: Interactive RAID Tutorial | RAID Levels Explained

Understanding RAID levels would be easy if you could simply watch your data being written to the drives.  RAID.EDU’s award-winning educational materials do just that, along with listing the pros and cons of every RAID level. Your JetStor system engineer will also make recommendations, which you can use to make the most informed decision about your RAID needs.

RAID LEVEL 0: RAID Level 0 Storage | Striped Disk Array | ACNC

RAID Level 0 requires a minimum of 2 drives to implement. Learn about RAID 0 advantages and disadvantages below.

RAID LEVEL 0: RAID Level 0 Storage | Striped Disk Array | ACNC

Characteristics and Advantages

  • RAID 0 implements a striped disk array, the data is broken down into blocks and each block is written to a separate disk drive
  • I/O performance is greatly improved by spreading the I/O load across many channels and drives
  • Best performance is achieved when data is striped across multiple controllers with only one drive per controller
  • No parity calculation overhead is involved
  • Very simple design
  • Easy to implement

Disadvantages

  • Striped RAID is not a "True" RAID because it is NOT fault-tolerant
  • The failure of just one drive will result in all data in an array being lost
  • Should never be used in mission critical environments

Recommended Applications

  • Video Production and Editing
  • Image Editing 
  • Pre-Press Applications
  • Any application requiring high bandwidth
