The calculator supports over the 10 major types of RAID setups. Various types of data units are supported for input, and while the cost is indicated in U. These can help you decide if the selected configuration is right for your particular case - be it for a server or a workstation. RAID stands for Redundant Array of Independent Disks, originally Redundant Array of Inexpensive Disks is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units. The purposes is to provide data redundancy, performance improvement, or in certain cases: both. The term was coined in a paper by Patterson at. The particular configuration depends on the required level of performance and redundancy. Each RAID level provides a particular balance across several variables: reliability, availability, performance, and capacity. The techniques to achieve that are: mirroring , in which identical data is copied onto more than one drive; striping , which partitions each drive's storage space into units ranging from a sector up to several mb; parity - in which information is striped across each drive, allowing the RAID to continue working even if one drive were to fail. Parity uses the XOR operation to allow information to be restored in case of a drive failure. Check the graphs below the levels table for visuals. RAID levels greater than RAID 0 provide protection against unrecoverable sector read errors, as well as against failures of whole physical drives. A detailed list of RAID levels supported by our tool follows. You can use the above images to better understand the intputs and outputs of the RAID calculator. In order to calculate the capacity of a disk array using our RAID capacity calculator, you need to know the peculiarities of each configuration, as some parts of it will limit the usable capacity of the array, like mirroring and parity.

Size of Each Drive Terabytes.

RAID 0 splits data across drives, resulting in higher data throughput. The performance of this configuration is extremely high, but a loss of any drive in the array will result in data loss. This level is commonly referred to as striping. Compared to a single drive, this mode tends to be faster on reads, slower on writes. This is a good entry-level redundant configuration. However, since an entire drive is a duplicate, the cost per megabyte is high.

This RAID calculator computes array characteristics by calculating the disk capacity, number, and type of the array.

Therefore it allows you to make an informed choice about the configuration of your next RAID array. It compares the following RAID levels:. If this is your first time configuring a RAID array, you might be unsure as to exactly what one is. Let's explain.

A hypothetical read speed of such a configuration is the sum of throughputs of the individual drives. Even though some RAID levels provide data redundancy, that doesn't mean it should be used as backup of your critical files. It does not require synchronized spinning, and each disk functions independently when single data blocks are requested. Disk mirroring is a good choice for applications that require high performance and high availability, such as transactional applications, email and operating systems. The performance of this configuration is extremely high, but a loss of any drive in the array will result in data loss. JBOD storage pools do not offer data redundancy. In order to calculate the capacity of a disk array using our RAID capacity calculator, you need to know the peculiarities of each configuration, as some parts of it will limit the usable capacity of the array, like mirroring and parity. Seagate Partner Program Portal Provides access to product training, sales and marketing resources, deal registration, and more to our VARs, Integrators, Resellers and other channel partners. RAID 6 becomes attractive when space and cost are important and sustaining multiple drive failures is required. Unlike RAID 4, parity information is distributed among the drives, requiring all but one to operate. Quantitative usage examples for various applications are for illustrative purposes. In addition, some of the listed capacity is used for formatting and other functions and will not be available for data storage. References 1 Patterson D.

As a result, both read and write performance are severely affected while a RAID 5 array is in a degraded state. The spare cannot be shared among multiple arrays. However, since an entire drive is a duplicate, the cost per megabyte is high. Performance does not degrade as much as in a RAID 5 array because a single failure only affects one array. Provides Suppliers with self-service tools targeted to the needs of their business. The double parity gives this RAID mode additional redundancy at the cost of lower write performance read performance is the same , and redundancy overhead remains low. Drive Capacity. Check the graphs below the levels table for visuals. RAID 0 combines two or more drives to increase performance and capacity, but provides no fault tolerance. The performance of this configuration is extremely high, but a loss of any drive in the array will result in data loss.
