RAID 5 Data Recovery Services

DataTech Labs® provides fast, professional RAID 5 data recovery services. Our expert recovery engineers will work around the clock to ensure that your critical data is retrieved as quickly as possible. We understand that each customer’s situation is unique, so we will analyze each hard drive in your RAID 5 array to determine the best recovery method for each of our clients.

RAID 5 Data Recovery Services

RAID 5 is one of the most common configurations. This array uses the same parity calculation as a RAID 3, however, instead of placing all of the parity on a single drive, it distributes it throughout all of the hard disks. There are four standard patterns for writing parity, Left Asynchronous stripe is depicted here. The width of the stripe or the amount of data that is written to each location can vary dramatically. The capacity and performance equations of a RAID 5 are very similar to that of a RAID 3.

What is RAID 5?

Today, RAID 5 is the most popular RAID configuration due to its improved performance and low cost of redundancy. Typically, RAID 5 is ideal for web and storage servers and databases. Generally, RAID 5 is implemented with hardware support for parity calculations.

RAID 5 has disk stripping like a RAID 1, but with parity. RAID 5, however, does not have a dedicated parity drive like a RAID 3, but instead has distributed parity across all disks. This helps increase space efficiency and speed compared to RAID 3 or RAID 4. You must have at least 3 hard drives and can go up to 32 hard drives. A RAID 5 two disk set is possible, but many implementations do not allow for this. In some implementations a degraded disk set can be made (3 disk set of which 2 are online). With disk stripping with parity, data is allocated between all the disks but have redundant duplicate information throughout opposite disks. When one drive fails duplicate data is throughout the good drives and can be rebuild lost data.

If more than one drive fails, however, data is lost due to inability to access enough fragments of data. Although RAID 5 offers fault tolerance, it is always important to have a well-planned backup strategy should more than one drive fail in the RAID 5 array.

Some typical scenarios that cause RAID 5 data loss include:

  • Controller Failure
  • Failure During RAID 5 Rebuild
  • Multiple Hard Drive Failures Past Point of Redundancy
  • Electronic Damage
  • Accidental File Deletion
  • Parity Loss or Damage
  • Accidental Formatting or Re-initialization

What to do when a RAID 5 Fails.

If you find your RAID 5 not functioning or receiving error messages, turn the system off immediately. Never use data recovery software on striped data.

Do not attempt to rebuild your array if you notice any unusual failure symptoms or error messages. Doing so could result in data loss and smaller chance for recovery. Operating a damaged RAID risks accidental overwrites, parity loss and other serious issues that can complicate the data recovery process. In our experience, keeping the array off as soon as you discovery a problem leads to a successful recovery most every time.

DataTech Labs Experience with RAID 5

At DataTech Labs, we know that RAID 5 failures cause serious complications for business. We will work around the clock to get your data back, FAST and securely. Our engineers are specifically trained to handle RAID 5 recoveries successfully no matter the manufacturer, controller, file system, parity type or variant:

  • Right Symmetric (Backward parity)
  • Right Asymmetric (Forward Parity)
  • Left Symmetric (Backward Dynamic parity)
  • Left Asymmetric (Forward Dynamic parity)
