  1. 1. RAID Technology<br />By Nicole Moore<br />
  2. 2. About RAID<br />Redundant Array of Inexpensive Drives<br />Created in the late 80s early 90s to create the same or greater storage capacity at a lower price. <br />Uses multiple hard drives for performance and reliability. <br />
  3. 3. RAID 0<br />Not a valid type of RAID.<br />Uses a method called “striping”.<br />ADVANTAGES<br />Increased performance. <br />No loss in data capacity.<br />DISADVANTAGES<br />No redundancy of data.<br />
  4. 4.
  5. 5. RAID 1<br />First real implication of RAID.<br />Uses a method called “mirroring”.<br />ADVANTAGES<br />Provides full redundancy of data.<br />DISADVANTAGES<br />Storage capacity is only as large as the smallest drive.<br />No performance increases.<br />Downtime required to change active drive during a failure.<br />
  6. 6.
  7. 7. RAID 0+1 and 10<br />Hybird form of RAID.<br />ADVANTAGES<br />Increased performance .<br />Data fully redundant.<br />DISADVANTAGES<br />Large number of drives required.<br />Effective data capacity is halved.<br />
  8. 8. RAID 1+0<br />RAID 10<br />
  9. 9. RAID 5<br />Most powerful form of RAID that can be found in a desktop computer system.<br />Requires a minimum of 3 drives to build.<br />Uses a form of binary math called parity.<br />Uses a method called “Hot Swap”.<br />
  10. 10. ADVANTAGES<br /><ul><li>Increased storage array performance.
  11. 11. Full data redundancy.
  12. 12. Ability to run 24x7 with hot swap.</li></ul>DISADVANTAGES<br /><ul><li>High costs to implement.
  13. 13. Performance degrades during building.</li></li></ul><li>(n-1)z = Array Capacity<br />n= number of drives<br />z= capacity <br />EX: Three 500GB (3-1)*5000GB= 1000GB<br />
  14. 14. RAID n<br />Offers higher reliability and more storage space than conventional RAID.<br />Allows customers to select the level of protection desired.<br />Currently implemented in Linux only.<br />
  15. 15. G-SPEED eS PRO XL<br />Created for small film studios and videoproduction.<br />Supports multi-stream uncompressed High Definition video and 2K workflows.<br />Web-based control panel lets users manage, configure, and monitor the system.<br />Faster.<br />More storage space.<br />Is Mac and PC-compatible.<br />
