RAID is born to balance either the data redundancy or performance improvement, or both. So far, though many variations have involved such as nested RAID, the standard ones are RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10. They are using different techniques to work in a specific situation. As a comparison, among the standard levels, it's the RAID 5 technology that reaps the benefits of enhanced data security, excellent performance, high data redundancy, and acceptable budgets.
- RAID 0 - striping
- RAID 1 - mirroring
- RAID 5 - striping with parity
- RAID 6 - striping with double parity
- RAID 10 - combining mirroring and striping
Briefly speaking, this RAID type consists of at least 3 disks for correct work, and you can add up to a maximum of 16 if needed. To get the best result of RAID 5 data recovery, it's necessary to know how RAID 5 operates. As the image shows, data blocks are striped across the drives and on one drive a parity checksum of all the block data is written. The parity data are not written to a fixed drive, they are spread across all drives. Using the parity data, the computer can recalculate the data of one of the other data blocks, should those data no longer be available. That means a RAID 5 array can withstand a single drive failure without losing data or access to data.
In conclusion, if 1 of 3 or above hard disks of RAID 5 becomes corrupted, damaged, or dead, no worry. Most renowned RAID recovery software can easily help you get the lost data back. But sometimes, it's not a single drive problem but two. How do you get over with it?
One catastrophic disaster is having 2 out of 3 hard disks broke down, especially at the same time. It's never possible to retrieve data from RAID 5 under such a circumstance. If by chance you use 5 or more disks arrays, you can put yourself together and try EaseUS RAID hard drive recovery software.
|How many hard drives failed||Chance of data recovery|
|2 of 3 hard disks||Zero|
|2 of 5~16 hard disks||
1. The more hard disks you are using, the higher the chance of successful RAID 5 data recovery
2. The more properly you handle the situation (i.e. Turn off the PC or RAID controller, or stop any operation on the RAID), the more likely you can rescue data without damaging the integrity
EaseUS Data Recovery Wizard is known as the most dependable, powerful, and efficient software that supports to rescue lost data from PCs, laptops, digital devices, hard drive (HDD, SSD), removable storage media (USB pen drive, memory card...), server, RAID, etc. Besides the ability to recover data from a corrupted hard drive or failed hard drive on RAID 5, it can also help recover data from the lost partition on RAID 5 and other levels.
Connect both the failed hard drives to your computer, and follow the guide below for a free trial. You can preview the scan results of lost data on the hard drives before actual data recovery.

Try to avoid two drives dying at once. As soon as one drive shows an amber light, stop writing new data or forcing RAID 5 array back online right away. For RAID 5 recovery under two failed hard drives, the EaseUS RAID recovery solution is the most time-saving and results-enhancing choice for quick and complete data recovery.
Though RAID 5 provides protection from a single drive failure, it's crucial to sense the danger of two hard disks malfunctioning at the same time, which makes full data recovery so difficult, even by professional data recovery services. It's of utmost importance to regularly back up RAID with a proper backup plan. A handy backup can guarantee a 100% possibility for RAID 5 data recovery with 2 problematic hard drives, or even more. Meanwhile, prevent disastrous consequences from the primary reasons for losing data.
- Malfunctioned controller
- Lost or deleted RAID partition
- Incorrect RAID volume configuration
- Viral damage or malware infection
- Sudden power outage
