Question

What type of RAID would be better for a home-based computer setup that has frequent power failures that could cause hard disk failures?

Answer 1

Answer:

Answer:

RAID 1 (YES !)

Explanation

RAID 1 have the disadvantage of disk space but over all its the best Option in the times of power failure .because remaining RAID does not support for a quick back up as RAID 1.

Advantages of RAID 1

1. RAID 1 offers excellent read speed and a write-speed that is comparable to that of a single drive.
2. In case a drive fails, data do not have to be rebuild, they just have to be copied to the replacement drive.
3. RAID 1 is a very simple technology.

Disadvantages of RAID 1

1. The main disadvantage is that the effective storage capacity is only half of the total drive capacity because all data get written twice.
2. Software RAID 1 solutions do not always allow a hot swap of a failed drive. That means the failed drive can only be replaced after powering down the computer it is attached to. For servers that are used simultaneously by many people, this may not be acceptable. Such systems typically use hardware controllers that do support hot swapping.
3. Ideal use

RAID-1 is ideal for mission critical storage, for instance for accounting systems. It is also suitable for small servers in which only two data drives will be used.

IF U Wanna know about RAID u can read from that webpages

Thank You

• RAID (redundant array of independent discs) is a technique for protecting data in the event of a drive failure by storing the same data in several locations on numerous hard discs or solid-state drives (SSDs).
• Computer storage systems that distribute or copy data across numerous drives are referred to as redundant arrays of independent discs (RAID). RAID storage functions in this fashion for two key reasons: it boosts data durability and I/O (input/output) performance.
• Redundant Array of Inexpensive Disks is referred to as RAID. In other words, RAID is a method of logically combining several drives into a single array. The concept is that these discs, when used in conjunction, will have the speed and/or dependability of a disc that costs more money.
• AID improves performance by distributing data across many discs and enabling balanced input/output (I/O) operation overlap. Replication of data increases fault tolerance since employing many discs lengthens the mean time between failures.
