Recover RAID 50

We can act on any scenario of data loss in RAID systems.

RAID 50 is a storage configuration that combines the benefits of RAID 5 and RAID 0. It consists of at least six hard drives, which are divided into RAID 5 groups and then combined into a RAID 0 group. RAID 5 provides data redundancy and RAID 0 provides increased performance. Combined, they provide high capacity, performance and data protection.

To understand how RAID 50 works, it is important to understand how RAID 5 and RAID 0 configurations work. RAID 5 uses parity to protect data, meaning that a disk drive is used to store parity information that can be used to rebuild data if a drive fails. RAID 0, on the other hand, uses striping to increase performance, which means that data is divided into blocks and stored across multiple disk drives to increase read and write speeds.

In RAID 50, disks are divided into RAID 5 groups, each with at least three hard drives. Data is distributed among the disks in RAID 5 groups using striping, which increases performance. Next, the RAID 5 groups are combined into a RAID 0 group, which also uses striping to increase performance. The result is a storage system with high capacity, high performance and high data protection.

Although RAID 50 is a robust and reliable configuration, data loss can still occur in some situations. One of the most common causes of data loss in RAID 50 is the simultaneous failure of two or more disk drives in a single RAID 5 group. In this case, the failure of one disk drive already causes data loss, but if more than one fails, the entire storage system could be compromised.

Another common cause of data loss in RAID 50 is RAID controller failure. If the RAID controller fails, the entire storage system can be affected and stored data can become inaccessible. It is important to choose a high-quality RAID controller and make regular backups to minimise the risk of data loss in case of controller failure.

In addition, RAID 50 does not protect against human error, such as accidental deletion of files or formatting of disk drives. If human error occurs, it is possible that data stored on the RAID 50 storage system will be lost.

Why Digital Recovery?

Digital Recovery is a company specialized in recovering RAID of all levels. We created a dedicated division to exclusively serve highly complex environments.

This business unit is known as Data Center Recovery Services and specializes in recovering data from RAID systems (0, 1, 10, 5, 50, 6, 60, vRAID, RAID-Z and JBOD), Storages (NAS, DAS and SAN) with Host Channel iSCSI, SAS and FC (Fibre Channel) from various manufacturers such as HP / HP, Dell / EMC and IBM / Lenovo, databases (Microsoft SQL Server, Oracle, MySQL, PostgreSQL, MariaDB, Firebird, DB2, Informix, Caché and Btrieve) and virtual machines (Microsoft Hyper-V, VMware, Citrix XenServer, Proxmox and Acropolis).

Even if you’ve received a negative diagnosis from a data recovery company, we are still happy to look into your case.

We have developed software and hardware technologies that enable us to act with precision and agility in advanced diagnostic and data recovery processes. The creation of technologies – many of them proprietary and exclusive – has kept Digital Recovery on the cutting edge.

One of our technologies, called Tracer, is capable of generating differentiated results in data recovery in Virtual Machines, Databases and RAID systems. Through millions of calculations and analysis of millions of records, this technology makes it possible to drastically reduce the execution time of projects, as well as increase success rates to almost 100%.

We are a Brazilian company with a subsidiary in Germany. Other partnerships for exchanging information and sharing technologies are made between companies in countries such as the United States, Russia and Ukraine.

In addition to providing services to governments, financial institutions, and small, medium, and large companies, Digital Recovery also provides services to other companies that also operate in the area of data recovery.

If your data is stored on a device located outside of the countries where we have labs, we have the technology to remotely assess and recover your data. If this is your case, please consult our department 24×7.

Should you need it, we can also provide you with a Non-Disclosure Agreement (NDA) in a language of your choice. Important to mention that our NDA is already adapted for GDPR. Please speak to one of our experts about this.

Being fully aware of the existing levels of pressure and urgency in data centre and cloud computing environments, we also offer a 24×7 urgency service. This type of service provides our customers with the ability to perform services 24 hours a day, 7 days a week, 365 days a year.

Answers from our experts

What happens when a hard drive fails in a RAID 50 system?

When a hard drive fails in a RAID 50 system, the data stored on that drive is rebuilt using parity information stored on other disk drives in the same RAID 5 group. The system will continue to function normally, but the total storage capacity will be reduced by the size of the failed disk drive. However, if more than one disk drive fails in the same RAID 5 group, data loss may occur

How does data loss occur in RAID 50?

Data loss on RAID 50 can occur in various situations, such as simultaneous failure of two or more drives in the same RAID 5 group, RAID controller failure, human error (such as accidental deletion of files), and exposure to external threats (such as cyberattacks). To minimize the risk of data loss on RAID 50, it is important to use reliable hard drives, implement cybersecurity practices, and make regular backups of stored data.

How does RAID 50 differ from RAID 5 and RAID 0 in terms of data loss?

RAID 50 combines the benefits of RAID 5 and RAID 0 to provide high capacity, performance and data protection. Compared to RAID 5, RAID 50 offers better performance, but is more susceptible to data loss in the event of simultaneous failure of multiple disk drives in a single RAID 5 group. Compared to RAID 0, RAID 50 offers better data protection, but has less performance.

Yes, it is possible to recover lost data on RAID 50, Digital Recovery specializes in recovering RAID systems. However, data recovery on RAID 50 can be more complicated than simpler storage configurations, such as RAID 1 or JBOD. It is important to seek help from qualified data recovery professionals to minimize the risk of permanent data loss.

RAID 50 uses distributed parity to protect data, which means that a disk drive is used to store parity information that can be used to rebuild data if one drive fails. In the event of corrupted data on a hard drive, RAID 50 will attempt to rebuild the data using the parity information. However, if there is corruption on multiple disk drives in the same RAID 5 group, data loss may occur.

Regardless of the number of disks that will be allocated in the array, the system will use the space equivalent to one disk for parity, ie to get the net space, just multiply the capacity of the disks by the number of disks subtracting one.

Example | Considering 5 disks of 3 TB each, totaling 15 TB of raw space.

Subtracting one disk we have a total of 4 disks of 3 TB, ie, 3 TB x 4 = 12 TB
