Realtime Support Data Recovery provides round-the-clock services for recovering data from RAID 5 systems. RAID 5 is a commonly used and secure level of RAID, requiring a minimum of 3 drives but capable of operating with up to 16 drives. In this configuration, data blocks are distributed across the drives, with a parity checksum written on one drive. The parity data is not confined to a single drive; instead, it is spread across all the drives as depicted in the diagram below. By utilizing this parity data, the system can reconstruct the information from any missing data block in case of drive failure. As a result, a RAID 5 array can tolerate the failure of a single drive without losing any data or access to it. While software-based RAID 5 setups are possible, it is advisable to use a hardware controller for optimal performance. These controllers often incorporate additional cache memory to enhance write speed.


Pros: Data read transactions occur at a high speed, whereas data write transactions are relatively slower due to the need for calculating parity. In the event of a drive failure, all data remains accessible even as the failed drive is replaced and the storage controller rebuilds the data on the new drive.

Cons: The impact of drive failures on throughput is significant, despite being tolerable. The intricacies of this technology are noteworthy. In the event of a 4TB disk failure within an array, the restoration of data (rebuild time) may extend to a day or more, contingent upon array load and controller speed. If another disk fails during this period, data will be irretrievably lost. In the event of a data loss emergency, we possess the capability to swiftly and effectively recover your critical data, irrespective of the cause.

Common RAID 5 Failures

Physical RAID Server Failure

If the components of your RAID 5 Server experience a physical breakdown, you may find yourself unable to access your critical daily files. This encompasses potential failures in the RAID 5 controller, RAM, power supply, motherboard, or backplane. No matter the cause of the RAID 5 server failure, our skilled RAID engineers are capable of retrieving your data.

Logical Failure of RAID 5 Server System

When the operating system, such as Windows, Mac, Linux, Novell, Unix, or VMware, experiences logical failures, it becomes corrupted. This can occur due to a virus attack, improper shutdown caused by a power surge or failure, an update that resulted in damage to the operating system, or user error. As a result, the system may fail to boot properly and display issues such as boot loops or blue screens. In such situations where data access is unavailable, it is recommended to consult with one of our RAID engineers for guidance on the next steps.

User Error

In the event of accidental deletion, corruption, or formatting of data on your RAID 5 server, we have a high probability of successfully recovering all your files. It is crucial for you to immediately cease usage and power off the server in case of user error, as any further activity significantly diminishes the likelihood of a complete recovery.

Physical Hard Drive Failure of RAID 5 Hard Drives

When the physical components of one or more hard drives in your RAID 5 server stop working, it is considered a physical hard drive failure. Typically, this kind of mechanical failure requires specialized clean room procedures to retrieve your data successfully. If a member drive in your RAID 5 setup experiences a mechanical breakdown, you will need the expertise of professional data recovery services to retrieve your important files. Our team of engineers possesses the necessary skills, tools, and facilities to fix your RAID 5 member hard drive and promptly recover your files within our controlled class 100 environment.

What to do when your RAID fails.

  • Do not run any chkdsk options like FSCK, or CHKDSK. These utilities can corrupt or destroy your file system.
  • Do not try to rebuild the RAID array. Doing so can wipe out data needed to recover the data you are seeking.
  • Do not remove several failed drives at once hoping to reinitialize the array.
  • Do not lose the correct order of the drives in the array.
  • Do not try to repair any damaged drives yourself.

Prior to shipping out the drives, it is important to label them in the correct sequence to facilitate virtual array reconstruction and save time. Additionally, it is essential to ascertain the type of RAID array, server specifications, filesystem, and operating system being utilized. If feasible, identify the faulty drives and determine which one failed most recently.

**Important** We need all original disks that were in the array the last time it was operating normally.

Despite the fact that the majority of data recovery companies do not provide a complimentary diagnostic for RAID retrieval due to the extensive time required, we differentiate ourselves by offering a fixed-rate fee for RAID data recovery. A specialist in RAID recovery will obtain relevant details from you during a phone consultation to provide an approximate understanding of the expected outcome. Although our fixed-rate fee covers RAID recovery, the cost may vary depending on potential scenarios. Our transparent fee structure surpasses any competitor’s pricing. We strongly advise contacting us before attempting to repair the RAID independently, as this could lead to irreversible damage.

What You Can Expect during your RAID Data Recovery Process:

  • You will be assigned a personal service representative for your project who will guide you through the process.
  • The data recovery process can take 7 to 10 business days based on many factors, see below.
  • The assigned service representative will be in daily communication with the data recovery technician working on your case and keep you up-to-date with the recovery progress.

How Long Does RAID Recovery Take?

Most customers inquire about the duration of the recovery process as one of their initial questions. However, providing a definitive answer is challenging due to the unique nature of each case. While some arrays can be reconstructed within a day or two, several factors may influence the overall timeframe for data recovery.

Hardware Condition – An operational drive allows for quicker data recovery compared to a severely damaged one that requires repair. Cases involving accidental deletion, formatting, viruses, and similar issues typically have a fast turnaround time, usually within 24 to 48 hours for most instances. However, there are occasions when the process may take longer. Drives requiring hardware recovery generally take around 7 to 10 days, but this duration can be extended depending on other factors.

Drive / RAID Array Size – A 4Tb drive, even when fully operational, can require up to 20 hours to complete a single scan for data recovery. Typically, multiple scans are necessary to locate all files effectively. As part of our professional data recovery process, we always create a clone of the drive first to minimize the risk of any accidents during data manipulation. Generally, anticipate an additional day for drives exceeding 500Gb in size or several days for those larger than 2Tb. Furthermore, very large arrays may entail significant time investment.

Number of Failed Drives – The turnaround time in striped RAID arrays can be impacted by the number of failed drives. If there are multiple failures, it is necessary to analyze all drives to identify which hard drive(s) went offline first, ensuring that the correct data is utilized during the rebuild process.

Availability of Donor Parts – When encountering hardware problems with drives, it is often necessary to obtain parts in order to restore the drive to a partially operational state, allowing for successful data extraction. While certain hard drive sub-models have readily available parts from our vendors, others do not. This may require extensive online searches and reaching out to other data recovery labs, sometimes taking weeks. In some cases, we may need to purchase a donor drive from abroad and await its delivery. Typically, this phase constitutes the lengthiest portion of the entire hardware level recovery process.

Functionality of Drive After Repair – Numerous brands of hard drives do not respond well to having their parts replaced, resulting in a significant decrease in performance following internal repairs. Since hard drives record magnetic data at a microscopic level, even minor variations in the manufacturing of components can lead to constant data re-reading. Although uncommon, certain drives may require a month or longer to retrieve all the data following such internal repairs.

Pricing for RAID Data Recovery?

We determine our RAID data recovery charges by considering the number of drives, their capacity, type, failure type, and file/system type in your RAID array. While our fees are standardized under our ONE RATE system, the cost may vary depending on different factors. Nevertheless, we assure you that our prices are highly competitive within the industry.

How Do I Get My Data Back After Recovery?

After the recovery process is finished, feel free to bring your own storage device for the recovered data. Typically, for RAID arrays, a high-capacity external hard drive is recommended. Alternatively, you can opt to buy a new external hard drive from us at a competitive price and we will transfer the data onto it. In the case of very large arrays with substantial amounts of data, special arrangements may be needed to transfer the data onto a NAS or another enclosure with RAID capabilities. If you need recovery from such an array, please get in touch with us for further information.
