Redundant Array of Independent Disks
Level : 0 1 2 3 4 5 6 7 10 53 General Info

RAID 3:
Parallel transfer with parity

The data block is subdivided ("Striped") and written on the data disks. Stripe parity is generated on Writes, recorded on the parity disk and checked on Reads.
RAID Diagram: RAID Level 3

RAID Level 3 requires a minimum of 3 drives to implement

CHARACTERISTICS/
ADVANTAGES		 DISADVANTAGES
  • Very high Read data transfer rate
  • Very high Write data transfer rate
  • Disk failure has a low impact on throughput
  • Low ratio of ECC (Parity) disks to data disks means high efficiency
  • Transaction rate equal to that of a single disk drive at best (if spindles are synchronized)
  • Controller design medium complexity
  • Very difficult and resource intensive to do as a software RAID

RECOMMENDED USES
Applications
  • Video Production and live streaming
  • Image Editing
  • Video Editing
  • Any application requiring high throughput
