The RAID( Redundant Array of Inexpensive Disk or Redundant Array of Independent Disk) is a single unit of many physical drives in a virtual manner. The RAID has different levels to increase the work. The RAID gives as a replacement to lose your data.RAID backup the data to the connected physical drives. The RAID provides improved performance and creates redundancy. Striping, parity, and Mirroring are Provides by RAID to enhance efficiency. RAID has many different configurations but has become old. More modern technology is introduced nowadays. People run like rabbits and RAID is the tortoise.
RAID 5 vs RAID 10
The main difference between RAId 5 and RAID 10 is the disk rebuilding methods. The default read and write programs can not change accordingly to the operations. The RAID 10 can read more and store the data in the drive with the replacement. The additional storage space is less expensive, and you need not spend much on buying extra devices for storage. Before buying things, make a configuration on that device.
The RAID 5 has a storage capacity of 6TB. That results in high performance and helps to cover drive failures. The RAID 5 can balance both the process of reading and writing. It has more workable storage compared to other raids. The RAID 5 is the most secured because the files are shared across all drives. The failed data can be recovered by parity data. The data here are stored only once and then duplicate by mirroring.
The RAID 10 has a minimum of four disks and no count in maximum. It is a mirroring data with striped disks. The services like email need high performance that is provided by RAID 10. It balance both the read and write process with high speed. RAID 1+0 is another name of RAID 10 with a combined called nested configuration.
Comparison Table Between RAID 5 and RAID 10
| Parameters of comparison | RAID 5 | RAID 10 |
| Definition | RAID 5 use parity data to improve the performance | RAID 10 use mirroring instead of parity data to improve performance |
| Usage | Data Parity is used in the disk | Data Mirroring is used in the disk. |
| Minimum Disk | Three in the minimum number of disk | Four in the minimum number of disk |
| Maximum Disk | No count in maximum | No count in maximum |
| Performance | Blocks are stripped | Blocks are stripped |
| Redundancy | Blocks are distributed parity. | Blocks are mirrored |
What is RAID 5?
In RAID 5, the data isn’t protected much. The RAID 5 gives a commensurate performance of RAID 0. The RAID 5 cannot create a new array. It has a combined unit called parity and stripped that results in good redundancy. The three si number od disks need my RAID % in minimum. The two drives present first can make equal by themselves and then transfer data to the third drive.
The RAID can do a replacement of failed drives without wasting time. The arrays present in parity are not equal in properties.
Those are determined by members present inside the parity data.
RAID 5 has the advantage of recreating the data. The RAID 5 takes more time to recreate the data. The recovery is impossible if a drive will lose data once.
The RAID 5 is famous among all the RAIDS. It can combine the best elements to give a better efficiency within the various RAIDS. It can also read the data that is present in some other device. The RAID 5 is categorized into four different parts. The disk will be swapped with data present in them. In simple it is an all-rounder.
What is RAID 10?
In RAID 10, the data are striped and mirrored. The RAID 1+0 is the other name of RAID 10. If two disks are mirrored then data will loss due to no parity instead mirror can take the responsibility here. The minimum requirement of the disk is four and no count in maximum. The mirror can make a copy called mirror copy which helps in the protection of data loss.
The RAID 1+0 and RAID 0+1 are equal and present in the opposite order in the layer. These both use an equal number of RAID levels. The storage capacity of RAID 10 is 20TB.The first 10TB for live data and the remaining 10TB for mirror copy. The levels present inside the RAID didn’t use the mirroring process. There is an alternative for RAID 10 that is called JBOD(Just a Bunch Of Disks).
The disk mirroring in RAID 10 is to duplicate the data and make a copy in every single storage connected to the controller. Mirroring can create one more layer for protection against data loss, and help in the fast recovery of data in case of failure. The RAID 10 boosts the speed of processing and gives a better performance in time.
Main Difference Between RAID 5 and RAID 10
- The RAID 5 use parity data for data redundancy and RAID 10 use mirroring for data redundancy.
- The RAID 5 has three minimum disks, and RAID 10 has four minimum disks.
- The RAID 5 read and write data but, RAID 10 do more faster than RAID 5.
- The blocks are stripped in RAID 5, and the blocks are mirrored in RAID 10.
- The RAID 5 causes a risk of data loss but, RAID 10 gives better protection.
Conclusion
Both hardware and software have RAID. On comparing both RAID 10 has more benefits and helps in data protection. The mirroring can do better performance in RAID 10. RAID 5 is better for reading options, and it is cost-effective. In RAID 5 the write operations are slow. Since RAID 5 uses a separate disk for parity, it is famous among the RAID methods or levels.RAID is an old technology trying to compete with modern devices. Many technologies are introduced nowadays people go with air and cloud for storage. They won’t depend on any physically carried devices. Before going for a new make sure to know the current trend and then invest you and your time.
