RAID systems are supposed to offer superb performance with increase speed data availability and reliability, however with so many variables and components involved regardless of the configuration RAIDs can and do fail.

When experiencing a RAID failure the best thing is to immidiately contact a DataRAID data recovery professional from the very onset of the failure. We wrote the book on RAID configurations Data Recovery (click here to see our storage.edu on RAIDs) so you can trust that whatever the kind of failure experienced by your array, chances are that there is more than a 90% chance that a DataRAID data recovery professionals can is still get your data back and fully restored.

If the data is critical and you do not have a recent backup available we recommend you do not attempt to rebuild, initialize or repair the array on your own. Any attempts of this kind are likely to further deteriorate your data and lessen the chances for a successful recovery.

DataRAID specializes in advanced emergency server RAID Data Recovery services to recover data from the most catastrophic of data loss situations. As RAID engineering experts we recover and support all RAID 0, 1, 3, 4, 5, 10, JBOD configurations and platforms running on HP Compaq, Dell, IBM and SUN server products.

DataRAID engineers consult and are able to recover lost data for all types of RAID configurations including:

RAID 0

RAID 0 uses a technique called data striping. Multiple hard drives are combined to make one large volume. RAID 0 can read and write faster than a non-RAID configuration, since it splits the data and accesses both drives in parallel. RAID 0 does not provide any data redundancy. RAID 0 requires at least two hard drives to be fully restored in order to perform a successful recovery.

RAID 1

RAID 1 mirrors or duplicates the content of one drive onto another equally sized drive. Mirroring provides optimal data integrity and immediate access to your data if one drive fails. RAID 1 allows you to use only half of the available capacity of your NAS device. RAID 1 requires at least two hard drives and must consist of an even number of drives. Data recovery for this type of configuration often takes less time, tools and resources assuming the mirrors were intact at the time of failure.

RAID 5

RAID 5 provides the best balance of data redundancy, performance and capacity. Like RAID 0, RAID 5 stripes all of the available drives into one large volume; however, the space equivalent to one of the hard drives will be used to store parity data. If the server was configured correctly and one hard drive fails, it should rebuild your data using the parity data. RAID 5 requires at least 3 hard drives. You may also use a RAID 5 configuration with hot spare, which reserves an additional hard drive that is swapped in immediately if a drive failure occurs. The total RAID capacity is the sum of all the hard drives minus the space of two drives. RAID 5 with hot spare requires at least 4 hard drives. All drives which are part of the array are required in order to perform a successful data recovery.

Non-RAID

In addition to RAID, you can also configure your server without using a RAID configuration. A non-RAID configuration, also referred to as JBOD (Just a Bunch Of Disks), does not allow any data redundancy and is slower than some RAID configurations. Data recovery for this configuration can vary in complexity depending on JBOD type and hardware configuration.

Our RAID data recovery service technicians and engineers are trained to handle most of the current server hardware platforms as well as commonly used legacy systems utilized on the market today.

To perform a RAID recovery , we often only require the drives, controller and storage devices which once stored the data. Every single RAID data recovery case which arrives at our labs receives high priority importance because we know and understand them to be a top priority for most organizations.
