RAID 01 vs RAID 10: Is There Any Difference?
Here you would find out:
- is there any difference in RAID 10 and RAID 01
- is there any difference in RAID 01 and RAID 10 recovery
Are you ready? Let's read!
RAID 10 benefits
RAID 10, or 1 + 0, is the unofficial name for stripe mirrors; that is, striping and mirroring are used to implement this array. The main disadvantage of this array is the low percentage of storage capacity utilization — only 50%. But for home systems, RAID 10 may be the best solution, and the cost is also not high. RAID 10, along with its high performance, has maximum protection; for example, an array of 10 disks can remain operational if up to 5 hard drives fail!
However, in order for this array to work, it will take only 4 disks, or more, but necessarily an even number of them.
Comparison of RAID 10 to RAID 01
If you compare RAID 10 vs RAID 01, then you can say that RAID 0 + 1 is often called a “mirror stripe”, and RAID 1 + 0 is called a “strip mirror”. In almost every sense, these two options for arrays have the same characteristics:
- Read speed and write speed are equally good
- The storage capacity for RAID 01 and RAID 10 is also the same; they allow you to use only half the volume, while the rest is needed in case of failure and recovery of disks.
RAID 01 is supported even by cheap RAID controllers, in some cases cheaper than RAID 10.
However, it should be understood that RAID 10 is used much more often, and is rarely more expensive. There is a simple and affordable explanation for this solution: protection and reliability of data is very important for owners of arrays, and RAID 10 can provide this to a greater extent.
Peculiarities of RAID 10 data recovery
Despite the high fault tolerance of RAID 10, there are still cases of damage to disks with missing data. In such cases, the best software for returning multimedia, documents and files of other formats is DiskInternals RAID Recovery.
Here it is possible to do both manual and fully automatic recovery to determine important parameters, such as array type, strip size, RAID controller type, disk order. All major Windows restrictions are ignored by the recovery process. The built-in recovery wizard helps you recover data without any hitches or errors. Virtual disks can be used as local disks available on Windows Explorer, etc. The application supports Unicode file names, and in addition multi-level folders are supported.
Here are the instructions on how to recover an array using DiskInternals RAID Recovery.
- 1. Download and install the RAID Recovery utility.
- 2. Run the recovery wizard and follow its instructions.
- 3. Select the desired RAID array to restore it.
- 4. Decide which scan you prefer: full or fast.
- 5. After scanning, the software will display all the results. Any of these files can be viewed for free.
- 6. To save these found files, you need to purchase a license for this software. Then complete this process by exporting data to the desired drive using the Export Wizard.
