Looking for professional RAID data recovery services?

raid data recovery

For more than 17 years we have successfully recovered data from all sorts of RAID servers, and performed hundreds of NAS data recoveries.

From two-drive mirrored RAID enclosures to over 48 drive complex Sun Microsystems RAID servers, IBM AS/400, HP EVA vRAID arrays with 24 RAID drives, we have seen and done them all.

Whether it’s a corporate RAID server or home NAS server running RAID 0, RAID 5, RAID 6 or RAID 10, quite often RAID-rebuild process causes more damage than good.

Usually, this happens due to RAID controller malfunctions or human errors when RAID drives are removed and incorrectly re-inserted into the RAID enclosure.

If you experienced a raid failure or raid rebuild process that didn't yield any desired results, we recommend stopping any attempts immediately in order to avoid any further damages to your raid server.

Call our raid specialists at 613-225-7870 for immediate help with your raid data recovery project.

Our team of dedicated experts will assist you with your raid data recovery issue and help you avoid downtime.

RAID configurations found in data critical applications these days.

RAID 0 is the level of RAID that does not live up to its name because it does not add redundancy. In fact, when run by itself, it reduces the level of protection for the data. When data is striped, it is spread across several disks with each block of data only being written in one place. The advantage here is not in protection but in performance. If any of the disks in the stripe fail, the whole array becomes unusable. This level of RAID is not used in mission-critical environments.

RAID 1 or "mirroring", has been used longer than any other form of RAID. This level of RAID provides redundancy by writing identical data to each member disk of the array, leaving a "mirrored" copy on each disk. Mirroring remains popular due to its simplicity and high level of data availability. RAID 1 provides very good data reliability and improves performance for read-intensive applications. At least two disks are required for the RAID 1 setup.

RAID 5 is the most common type of RAID. It's a solid performer offering great redundancy. RAID 5 distributes parity across some or all of an array's disk drives. Fault tolerance is maintained by ensuring that the parity information for any given block of data is placed on a drive separate from those used to store the data itself. The speed of a RAID 5 array can be "adjusted" by trying different stripe sizes until one is found that is well-matched to the application being used.

RAID 6 stripes blocks of data and parity across an array of drives like RAID 5, except that it calculates two sets of parity information for each parcel of data. The goal of this duplication is solely to improve fault tolerance; RAID 6 can handle the failure of any two drives in the array while other single RAID levels can handle at most one fault. Performance-wise, RAID 6 is generally slightly worse than RAID 5 in terms of writes due to the added overhead of more parity calculations.

RAID 10 and 01 are the most popular of the multiple RAID levels. They combine the best features of striping and mirroring to yield large arrays with high performance in most uses and superior fault tolerance. RAID 01 is a mirrored configuration of two striped sets; RAID 10 is a stripe across a number of mirrored sets. RAID 10 provides better fault tolerance and rebuild performance. RAID 10 and 01 setup combines the speed of RAID 0 with the redundancy of RAID 1 without requiring parity calculations.

RAID 50 is a combination of RAID 5 and RAID 0. This level of the array includes both parity and disk striping across multiple drives. RAID 50 is best implemented across two RAID 5 arrays with data striped across both disk arrays. High data transfer rates are achieved due to its RAID 5 array segments and high I/O rates for small requests are achieved due to its RAID 0 striping. RAID 50 offers the highest level of redundancy and performance. RAID 50 requires a minimum of six drives for its implementation.

Synology Hybrid RAID (SHR) is an automated RAID management system that makes storage volume deployment easier than traditional RAID systems. Synology Hybrid Raid is found in Synology NAS systems. It's an optional, Linux-based RAID management system. You can expand an SHR volume by changing the drives one at a time, and allowing the NAS to repair the volume. As soon as enough redundant storage is available, the SHR volume will expand the usable storage capacity.

X-RAID is an auto-expandable RAID technology that is available only on ReadyNAS systems. With X-RAID, you can start out with one hard disk, add a second disk for data protection, and add more disks for additional storage capacity. X-RAID's single-volume architecture has two major advantages that include easy system management and auto-expansion. This type of X-RAID is found on Netgear NAS systems. X-RAID reserves the capacity of one disk for data protection.

FreeNAS is a Free and Open Source Network Attached Storage (NAS) software appliance. FreeNAS uses the ZFS file system to store, manage, and protect data. ZFS provides advanced features like snapshots to keep old versions of files, incremental remote backups to keep your data safe on another device without huge file transfers, and intelligent compression, which reduces the size of files resulting in faster data transfers. /FreeNas.org/

ZFS is a combined file system and logical volume manager designed by Sun Microsystems. ZFS is scalable, and includes extensive protection against data corruption, support for high storage capacities, efficient data compression, integration of the concepts of filesystem and volume management, snapshots and copy-on-write clones, continuous integrity checking and automatic repair, RAID-Z, native NFSv4 ACLs, and can be very precisely configured. /Wikipedia/

Universite du Quebec recovery

It was an emergency. Hundreds of employees had to be up and running by Monday morning. We sent the hard disks to Capital Data Recovery who worked over the weekend and kept me informed all the time. These people did everything to help us get our files. Everything was recovered 100% but we couldn't get our files back because no courier would work on Sunday. We downloaded Exchange files from Capital's FTP. That was the most critical data we needed. The rest of the files were shipped to use overnight on Monday. No employee noticed a problem when they came to work on Monday. Everything was running the way it was before. We, technical people know what it takes when such disaster occurs. My satisfaction with Capital Data Recovery is 110%.

    After having broken my external Drive (2Tb), dropping on the floor. I brought it to Capital Data Recovery (CDR). I was unsure if it would be recoverable. What a joy to receive the email today that said … More "Good News!" All important files were saved and some picture and video files were put aside in distinct files. Thanks and kudos to Levon Kazariyan and his team!

    I recently had the pleasure of engaging with Levon at Capital Data Recovery, and I must say, their service exceeded all expectations! From start to finish, the experience was seamless and truly remarkable. … More
    First and foremost, I was struck by the transparency and honesty displayed by the company. They were upfront about their pricing, services, and timelines, which instantly instilled confidence in their integrity.
    In conclusion, I cannot recommend Capital Data Recovery highly enough. Their honesty, professionalism, and dedication to customer satisfaction make them a standout in the industry. If you're looking for top-notch service from a company you can trust, look no further.
    a special thanks to Levon!!

    Great experience, highly recommend. I contacted them about a dead external hard drive that had invaluable family photos, videos, and memories. They provided a fair quote and they have a "no data - … More no fee" policy, so they only charge you if the data is successfully recovered. I worked with Levon, who was very professional, caring, and understood the value of this data. He was also very patient and careful when we ran into problems with the new hard drive for the data to be transferred to. Thank you for the great experience, I'm grateful that my data and invaluable family memories have been preserved.
