DISK REDUNDANCY ASSIGNMENT
KENDAL JEFFERSON
1. What does RAID stand for?
Redundant array of inexpensive disks
2. When would we use RAID?
When you want to combine multiple disk drive components into a logic unit for the purposes of data redundancy or performance improvement
3. Define the following types of RAID.
a. RAID 0: provides no redundancy, splits or stripes the data across drives, resulting in higher data throughput.
b. RAID 1: usually preferred to as mirroring. Provides redundancy by duplicating all the data from one drive on a second drive so that if either drive fails, no data is loss.
c. RAID 5: stripes data at a block level across several drives and distributes parity among the drives. No single disk is devoted to parity.
d. RAID 6: a combination of RAID levels that utilize multiple RAID 5 sets striped in a single array. A single hard drive failure can occur in each of the RAID 5 sides without any loss of data on the entire array. If more than one disk in any of the RAID 5 arrays all the data in the array is lost.
4. Why is RAID 0 of any use if it offers no redundancy? It can be used to increase disk performance.
5. Why do you think that RAID 1 can be most expensive? Why would people utilize it if it’s so costly? It requires more disk space because you are mirroring the data. People prefer this because your data is always backed up.
6. If you, as a home computer user, were to purchase a form of RAID, which would you choose and why? I would use RAID 1 because I would want my files backed up for security in case something went wrong.
7. What is the difference between software RAID and hardware RAID? RAID hardware requires you use specialized hardware to handle the drives and it is more reliable.
RAID software is cheaper and it uses up a chunk of the host processor.
