Which Of The Following Characteristics About Raid Is Incorrect?

What is RAID?

RAID stands for redundancy array of the independent disk it is defined as the method to store data on various places to any kind of hard disks or any solid-state for the protection of the data in case of hazardous. Here a question has been asked what statement is incorrect about the RAID? In the elective paper. We have gathered the information about RAID what are the types, the pros and cons, and the working of the RAID. To know more detail about it scroll to the end.

RAID and its working

RAID is a way of the drives connected in a way that helps the speed and the performance rate of the drive, it is not for the personal computer it is used in servers and the high computer with greater functions. Different techniques are used in RAID.RAID cannot be used as the proxy for data storage which means if any kind of problem occurs the data backup can’t be stored in it.

There are different modes of the RAID which are discussed below:

RAID 0: It is also known as the stripped disks in which data is even between drives.

RAID 1: The Mirror disk with the same data in both drives.

RAID 3: Striped set with dedicated parity, the data is even between two or more and the dedicated drive.

RAID 5: Stripped disk with dedicated parity, the data is even between three or more drives the parity is between disk.

RAID 10: 1+ 0 striped sets of mirrored subsets four or more disks are made into two mirrors which are stripped.

Working of the RAIDS:

Raid put the data of various disk and allow the input and output operations to crossover in a balanced way, which cause the performance to improve. The multiple drives enhance the meantime of the failure to store the data redundancy which in return enhances the fault tolerance. RAID is the single logical drive operating system. Disk mirroring is also applicable with the help of the RAID.

Pros and cons of the RAID:

Pros:

The prose of the RAID is in the following:

• The cost has been improved because the low-price disk is more in demand.
• Various hard drives allow RAID to enhance the single drive capacity.
• Through configuration, the speed and reliability are affected.
• With RAID 0 single drive RAID the reading and writing are efficient.

CONS:

The cos of the RAID is in the following:

• The traditional RAID is cost-effective than the nested RAID, because of the disk’s requirements.
• The RAID 1 AND 6 only manage till the single drive failure.
• The data in the RAID array is vulnerable as long as the drive is failing and is not replaced.
• Nowadays the capacity of dives is good rather than RAID was implemented, the time taken for the rebuild is long.
• If one disk fails then the change then the other ones have the vulnerability is quite high.

Which of the following characteristics of RAID is incorrect?

• High capacity of storage.
• Fast access speed.
• Reliability is high.

One high-capacity hard disk drive.

Answer: The correct statement about the characteristics of the incorrect RAID is one high-capacity hard disk drive.
