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 0 is useful because of it’s low cost and overhead. It is common among home users and often uses two hard drives. However, RAID 0 is not fault-tolerant. If one drive fails, all data in the array is lost. RAID 0 is best used for storage that is noncritical but requires high-speed reads and writes.
RAID 0 splits (“stripes”) data evenly across two or more hard drives without parity information, redundancy, or fault tolerance. This makes is a fairly simple system to set up. However, because RAID 0 provides no fault tolerance or redundancy, the failure of one drive will cause the entire array to fail since data is striped across all disks. The main reason a RAID 0 configuration is typically implemented is because of speed and performance. Caching live streaming video and video editing are common uses for RAID 0 due to speed and performance.
Since RAID 0 does not use data redundancy, the failure of any physical drive in the striped disk set results in the loss of the data on the striped unit and, consequently, the loss of the entire data set stored across the set of striped hard disks. In such a case data recovery is the only option to prevent permanent loss of data.
As mentioned previously, because RAID 0 configurations have no type of redundancy built in, it provides virtually no 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 – it cannot replace a backup plan.

Data stored in a RAID 0 array is more at risk for data loss than any other type of RAID array because it offers no redundancy.
In the event of a RAID 0 failure resulting in data loss, you can try to run some RAID 0 data recovery software. However, even the best RAID 0 data recovery software cannot fix most problems that cause RAID 0 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 0 data recovery companies.
Our advise is simple. If you have encountered a RAID 0 failure resulting in potential data loss, give DriveSavers a call. Raid 0 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 0 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 0 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.
