RAID 0 vs RAID 1: Comparison of two different RAID types
Here you will find out:
- comparison between RAID 0 vs RAID 1
- what benefits of RAID 1 or RAID 0
- how DiskInternals can help you
Are you ready? Let's read!
What is RAID 0?
This RAID option consists of two physical hard drives that work as a unit.
The advantages of this configuration include faster implementation of tasks; in theory, it should be twice as fast. However, in practice, this is not always the case, and sometimes users generally cannot notice the difference. There is also a doubled risk of damage to the array. This is more like the truth and certainly cannot be a good indicator. But, if the data is not so important, then you can use this RAID 0 and periodically make copies of important data.
What is RAID 1?
The components of RAID 1 are not much different from RAID 0: the same two hard drives are combined into one array.
The striking difference is the speed of writing and reading: in RAID 1 they worked on this and achieved the desired result.
In addition, your data here is more secure.
Therefore, this is also a good option for an array.
Comparison: RAID 0 vs RAID 1
Since these arrays are very similar, there is a need to compare RAID 1 vs RAID 0, which we will now try to do according to the main features.
1. Distribution of data on disks:
- RAID 1 - information is divided into disks separately.
- RAID 0 - information flows evenly on both disks.
2. Fault tolerance:
- RAID 1 - present
- RAID 0 - absent. In RAID 0, maximum disk usage.
3. Increase read/write speed:
- RAID 1 - the write and read procedure is slower due to redundancy.
- RAID 0 - should be faster for both, but not always.
4. The required number of disks to create RAID:
- In both cases, two hard drives.
- RAID 1 is more reliable, since when you reset one disk, the second one is still able to work correctly for some time.
- RAID 0 is not safe and the data undergoes spontaneous disappearance.
How data can be restored from RAID 0 or RAID 1
You should not look for complex and expensive ways to recover lost files; you can just download DiskInternals RAID Recovery and export the recovered files to a suitable device.
This application has constantly been improved for more than 15 years. Satisfied customers constantly use the services of DiskInternals and highly recommend this application to colleagues and acquaintances. The application recovers data primarily from Linux, as well as from NAS and UNIX. It is possible to recover data from RAID 0, 1, 0 + 1, 1 + 0, 1E, RAID 4, 5, 50, 5EE, etc.
Disk imaging is also available here. At the beginning of the process, you can activate the Recovery Wizard and feel more confident and relaxed. Any questions you may have can be addressed to technical support after you have a license, which can be bought at any time of day on the company's website and thus get more features and options.
