Q

RAID0 - Method, Min # of Drives, Common Usage?

A

Stripping = SPEED
Requires min of 2 Drives.
Heavy Read Operations

  • If 1 Drive fails, all Data Lost.

+ High Performance Speed
- Data is LOST if one disk fails

Q

RAID1 - Method, Min # of Drives, Common Usage?

A

Mirroring = REDUNDANCY
Requires atleast 2 Drives

  • Primary Purpose of RAID1 is Redundancy - Slows things down because you’re Mirroring/Writing the Data Twice.

+ Fault Tolerance, High Read Performance
- LAG for Write Ops, Reduced Storage by 50%

Q

RAID5 - Method, Min # of Drives, Common Usage?

A

Stripping + Parity = SPEED + REDUNDANCY
Requires Minimum of 3 Drives.
Normal File Storage & App Servers

  • Stripping occurs with 2 of the 3 Drives, and the 3rd Drive does Parity.
  • If 1 Drive Fails, data can easily be recreated - Replace the Failed Drive and Rebuild the Array.
  • If more than 1 Drive Fails, you can’t rebuild the Array.

+ Speed and Fault Tolerance
- LAG for Write Ops, Reduced Storage by 33%

Q

RAID10 - Method, Min # of Drives, Common Usage?

A

Stripping & Mirroring = HIGH SPEED + HIGH REDUNDANCY
Requires Minimum of 4 Drives
Highly Utilized Database Servers

  • 2 of the Drives are RAID1 and Mirrored to the other 2 RAID1 Drives
  • If you lose a Mirrored PAIR, you are in trouble.
  • You can lose 2 Drives as long as they aren’t in the same Mirrored Pair.
  • Includes Stripping across two drives for faster performance and Mirroring of the Stripped Array for Safety.

+ Write Performance and Strong Fault Tolerance
- Reduced Storage by 50%, Limited Scalability

Q

RAID6 - Method, Min # of Drives, Common Usage?

A

Stripping + Double Parity
Requires 4 Drives Minimum
Large File Storage & App Servers

  • It’s like RAID5, Stripping with Parity, but instead of 1 Parity Drive you get 2 Parity Drives.
  • You can lose up to 2 Drives before Data Loss.

+ Extra Level of Redundancy, High Read Performance
- Low Write Performance, Reduced Storage by 40%
