What type of RAID volume is used for fault tolerance and only requires two drives?

RAID 1 is mirroring without parity or striping. It requires a minimum number of two drives and has a fault tolerance of one.
RAID 1 works by writing data to both drives, thereby producing a mirrored set. When the read is requested, it is serviced by the drive that has the lowest seek time plus rotational latency.
An example of this set-up is two 1TB drives in RAID 1 that have a combined total of 2TB of storage, but because they are in RAID 1, the effective storage space is 1TB as data is mirrored on both drives. It is effectively a real-time back-up system. If one drive fails, data is not lost.

Does striped volume offer fault tolerance?
No
Which volume provides fault tolerance?
raid5
What type of volume uses 50 percent of available space to provide fault tolerance for the volume?
RAID-5
What type of volume uses 50 percent of available drive space to provide fault tolerance for the volume?
raid 5
Explain the difference between a spanned volume and a striped volume and specify which -if any- provides increased performance and or fault tolerance?
A striped volume writes to the physical disks evenly, rather than filling allotted space one and then moving to the next. Striped volume increases the performance while, striped and spanned volumes does not provide fault tolerance.
Why doesn't RAID 0 provide fault tolerance?
RAID 0 does not provide fault tolerance, it's to use space form two or more physical disks and increases the disk space available for a single volume. (pg 406)
What is RAID technology in server?
RAID technology uses multiple disk drives to achieve either fault tolerance or an increase in read and write performance.
Which topology has the most fault tolerance and redundancy?
The star bus topology has the most fault tolerance.
Does RAID 0 provide fault tolerance?
RAID 0 does not provide any fault tolerance.
What is the importance of fault tolerance in network?
Fault tolerance refers to the ability of a computer network to continue operating properly in the event that one of its components fail. Fault tolerance is therefore important in any network.
What is the advantage of fault tolerance?
Fault Tolerance means that the system will not fail and not stop during the execution (or operation) when a fault is occurred, so fault tolerance mean the ability of handling with faults without stopping the system.
What RAID implementation provides no fault tolerance?
RAID level 0RAID 0RAID 0 (block-level striping without parity or mirroring) has no (or zero) redundancy. It provides improved performance and additional storage but no fault tolerance. Any drive failure destroys the array, and the likelihood of failure increases with more drives in the array.
