Raid Disk Space Utilization Calculator Tool

RAID Calculator

This tool calculates RAID specifications, helping you to choose the best array for your storage requirements.

RAID Calculator

The components of a RAID system interact in complex ways, leading to wide variance in usable space, service speed and fault tolerance from one configuration to the next. Each element of an array affects performance, and various configurations have specific benefits and drawbacks. This comprehensive tool calculates important specifications for a RAID array according to three key metrics.

RAID Levels Overview

RAID systems combine multiple disks into a single unit to achieve greater performance and increased fault tolerance.

Various RAID levels balance the advantages by combining sets of operations, including:

  • Distributing Data Across Multiple Disks, or "Striping".
  • Copying Data on a Second Drive, or "Mirroring".
  • Incorporating Parity Blocks to Recover Threatened Data.
  • Coordination of Reading/Writing Tasks by Disk Array Controllers.

RAID 0 systems increase read/write speeds by using striped sets to record fragmented data across several disks simultaneously. Because RAID 0 arrays don’t include data redundancy, disk failure can still result in lost files. For greater fault tolerance, RAID 1 is the simplest option. These systems safeguard their contents with disk mirroring capabilities, creating total redundancy for effective data protection.

RAID 5 achieves fast write speeds with striped sets while protecting data by distributing parity across several drives. Of all the options, RAID 5 is the most popular for use with web servers. RAID 6 arrays are similar to RAID 5, but an extra parity block provides stability even if two drives fail.

Offering the greatest fault tolerance, RAID 10 combines the benefits of striping and mirroring to maximize performance and protection from failed components. RAID 0+1 arrays invert the RAID 10 configuration with mirrored sets of striped arrays.

To determine the performance data of a given RAID array, enter the parameters into the fields above and click "calculate".

    Data Recovery Success!

    Of course there is never a convenient time to experience a storage media crash, especially when, due to a bizarre combination of circumstances, your cloud storage account happens to be inaccessible as well. SDR was very attentive and efficient in facilitating a quick recovery and turnaround of my data. The fact that they assign you a dedicated rep from start to finish is an excellent idea when one considers that, by the time you are contacting a data recovery service, you are already in an elevated state of frustration/anxiety. I would have no hesitation in recommending them to anyone who finds himself in a similar situation as I found myself.

    Miraculous RAID Drive Recovery

    While on an extended vacation my RAID system inexplicably crashed. Power supply seemed to be the culprit, but alas that was not the issue. All data on the system seemed lost after a relatively extensive local expert's investigation. Although I 'thought' I was fully backed up in the Cloud, it turned out that several years of Outlook data was not properly configured for the backups. I then forwarded the drives to Secure Data. Jeff Hart and his team did an incredible job of fully recovering all content on my drives. Cannot thank them enough. Lesson learned: Validate your backups, and contact Secure Data when all else fails. Great results.

    Great Job - better than I thought

    Ryan was very professional and the process is nicely laid out for clients. Initially we thought that the file structure was going to be obliterated but when I got my drive, much to my surprise, not only was most of my data recovered but the file structure was all there both for the recovered files and the ones that were damaged so I can easily go in and see what files were lost in case I can go find them in other places.

    Thanks. Definitely recommend this service and Ryan.

    Great customer service

    We had another company look at our hard drives and they couldn't get any data back for us. They recommended we contact Secure Data Recovery. Ryan helped us through each step and we now have our files back and are using them again.
    Thanks for your service.
