About RAID 50
RAID 50 is not widespread enough, so most users know little about it. In fact, it is 2 RAID 5 arrays united in RAID 0. The main mechanism for distributing information is interleaving with parity. It should be understood that, since two RAID 5 arrays are used simultaneously, the write speed is significantly increased.
However, all the free space cannot be used, as two disks must be reserved for possible recovery. This type of array is very expensive, because 1) it can consist of at least six disks, and 2) the controller will cost a lot of money. Therefore, only large corporations can afford such an array.
About RAID 10
RAID 10 is also a hybrid array, only it consists of two RAID 1 arrays united in RAID 0. Here, the data distribution mechanism includes interleaving mirroring. This array can withstand the failure of one disk with subsequent restoration of data. This RAID type is slightly cheaper, since it can work on four disks (their number must be even), and the controller costs a little less.
RAID 50 vs RAID 10: General Features
For comparing RAID 10 to RAID 50, it is best to look at the main characteristics of the arrays:
- 1. Write and read speed: RAID 50 has high performance, much higher than RAID 10.
- 2. Free space for data: RAID 50 has a fairly large amount of free space (more than just in one RAID 5). RAID 10 cannot boast of this, since it allocates as many as two disks for copying data.
- 3. Redundancy: Both arrays have redundancies, but again, RAID 50 has greater redundancy than RAID 10. This is due to the storage mechanism: RAID 50 uses striping with parity, while RAID 10 does not have parity.
- 4. File recovery capability: RAID 50 has this capability, but the recovery process will take a very long time. Moreover, if two or more disks are damaged, recovery is unlikely to happen. RAID 10 can also recover data from a damaged disk and it will be much faster, since mirroring is used here. However, it should be understood that if in the mirror set, two or more disks fail, you are out of luck; the data can no longer be restored.
- 5. Cost: RAID 50, as mentioned above, costs more, since you need more disks for the array to work and the controller is more expensive. In this regard, RAID 10 will be more budget-friendly.
These are the main arguments in favor of one or the other array. The choice is ultimately yours.
RAID 10 vs RAID 50 Data Recovery
DiskInternals RAID Recovery can perform data recovery on both RAID 10 and RAID 50. It is developed using advanced technologies and equipped with additional functions for seamless and safe data recovery. DiskInternals RAID Recovery supports both automatic and manual detection of important parameters, such as array type, RAID controller type, disk order, and lane size.
Below you can learn about how to use this application:
First, download RAID Recovery to your PC or server, and then install the software on Windows.
Open the application and enable the Recovery Wizard. Then select an array that needs to be restored.
Next, you will be asked to select a scan mode:
- Fast recovery
- Full recovery with deeper scanning
