1What is RAID?Redundant Array of Independent/Inexpensive Disks
2What is the difference between software and hardware RAID?Software RAID is built into the OS and hardware RAID has a controller installed onto the MOBO for RAID
3What does it mean when a device is hot swappable?You can remove them when the system is still on without any damage occurring to the device and data is retained
4What is RAID 0 (Striping)?Stripes (splits) a file between multiple drives
High performance, optimal disk space
No redundancy
Can cripple a network
5What does redundant mean?Multiple ways to access information if one source fails
*something that has “high redundancy” means there’s many pathways
6What is RAID 1 (Mirroring)?The file is duplicated (mirrored) across multiple drives
Doubles the amount of dive space
High redundancy and 100% uptime
7What is RAID 5 (Striping with Parity)?The file is striped between drives
One block however is a a parity block in each drive
Data can then be reconstructed using the parity block
Good use of disk space
High redundancy with decent uptime
Need at least 3 drives
8What is RAID 10/ RAID 1+0 (Stripe of Mirrors)?The files are striped across drives
Then there would be a mirror of each block from each drive
The mirror would also be striped
Minimum of 4 drives
