Which of these would be true about RAID 1?
A) In the case of a failure, an exact duplicate of your data exists
B) RAID 1 is generally much faster than RAID 0
C) In the case of failure, the array is broken and data is unrecoverable
D) Data is made redundant through the use of parity blocks
E) RAID 1 is a hard worker who is always on time and isn’t afraid to go the extra mile
The answer: A) In the case of a failure, an exact duplicate of your data exists
RAID 1 may not be the fastest form of RAID, but it’s certainly one of the safest. With RAID 1, data is completely duplicated between drives. If a drive were to fail, the remaining drive would continue to provide uninterrupted data reading and writing.

Want to know more? Watch “RAID.” RAID arrays are common ways to provide high-throughput and redundancy for groups of hard drives. In this module, you’ll learn how the different RAID technologies can be used to build large-scale storage infrastructures. You’ll also learn the advantages and disadvantages of the different RAID technologies and how hardware and software RAID compares. |
