RAID 50 (5+0)
Standard RAID (redundant array of independent disks) levels comprise a basic set of RAID configurations that employ either striping, mirroring, or parity to create large reliable data stores from multiple general-purpose computer hard disk drives (HDDs).
RAID 50 (also known as RAID 5+0) is a nested or “hybrid” RAID configuration that provides the distributed parity of RAID 5 with the straight block-level striping of RAID 0. As a RAID 0 array striped across RAID 5 elements, minimal RAID 50 configuration requires six drives.
RAID 50 offers better write performance, increased data protection and faster rebuilds than a standard RAID 5. Performance does not degrade as much as in a RAID 5 array because a single failure only affects one array. One disadvantage to RAID 50 is that it needs a sophisticated controller.
Up to four drive failures in a RAID 50 configuration can be overcome as long as each failed drive occurs in a different RAID 5 array. Otherwise, data recovery is the only option to avoid permanent loss of data.
While the RAID 50 configuration can provide protection against and recovery from hardware defects or defective sectors/read errors (hard errors), it does not provide any protection against data loss due to catastrophic failures (fire, water), multiple disc failures, user error, software malfunction, or malware infection. For valuable data, RAID is only one building block of a larger data loss prevention and recovery scheme – it cannot replace a backup plan.

RAID 50 servers are usually extremely reliable and offer a comfortable amount of redundancy. However, like any RAID configuration, data loss is a real possibility as a result of drive failure both physical and logical. Raid 50 data recovery software is available but even the best programs cannot fix most problems that cause RAID 50 data loss in the first place. Data recovery software isn’t likely to help in severe cases. DIY data recovery utilities can even make things worse and virtually impossible for even the best RAID 50 data recovery companies.
Our advise is simple. If you have encountered a RAID 50 failure resulting in potential data loss, give DriveSavers a call. Raid 10 data recovery is what we do! We are experts in the field with an extraordinary success rate backed by over 30 years as the leader in data recovery.
Our certified RAID 50 data recovery engineers have the in-depth knowledge and technical expertise that comes from over 30 years of data recovery experience, allowing us to achieve the highest success rate in the industry. DriveSavers Enterprise Systems Group specializes in recovering data from all operating systems and all types of high-capacity devices including redundant arrays of independent disks (RAID), network attached storage (NAS), storage area networks (SAN) and multi-disk servers. We routinely rescue lost databases, ERP accounting systems, mail servers and other mission-critical data for organizations of all sizes.
Because RAID devices are constructed with unique components and configurations depending on the manufacturer, it is imperative that our data recovery engineers have in-depth knowledge of the various proprietary metadata structures and hardware.
Technical alliances with RAID controller manufacturers have enabled our engineers to develop proprietary techniques, tools and technologies that aid in data recovery from RAID devices based on solid-state drives (SSDs), hard disk drives (HDDs) and more complex hybrid and tiered storage environments. All major Raid 50 manufacturers authorize our data recovery services so working with DriveSavers will not void your original warranty.
Extreme damage and data loss can result if any particulate matter enters an HDD. DriveSavers Certified ISO Class 5 Cleanroom is the most advanced data recovery Cleanroom in the industry. This dust-free, static-free, temperature– and humidity-controlled environment maximizes our data recovery successes on all storage devices by protecting the platters and electronic components on the drives from “killer particles” while they are open and vulnerable to damage.
