If you’re operating on large media files, then it’s quite likely that you will be in the market for the need of more storage options for the lack of storage that a single drive can provide. While you could just randomly put a bunch of drives together, a RAID array is considered to be a better alternative since it engages multiple drives collected to increase speed, protect your data, or both.
RAID (redundant array of independent disks) in simple terms refer the working of several hard drives combined together and are working as one single super hard-drive. The RAIDs are available in different kind of configurations and offer fault tolerance, reinforce the overall performance, along with increasing the storage capacity of the system. Read on to find out which prevalent RAID configuration might suit your needs.
1. RAID 0 or Striping:
They are primarily structured for a substantial increase of Input/output performance. In this level we find the use of strips – a predefined number of contiguously addressable disk blocks. Assortment of such strips affiliated in multiple disks is identified as the stripe. The least number of drives essential are two, with super high read/write speeds reliant on the number of hard drives or solid-state drives in the configuration, and with the consumption capacity at 100 percent. Classically RAID 0 is utilized for high-end tasks like ultra-high-definition video editing, or for high rendering systems.
2. RAID 1 or Mirroring:
A simple and unswerving way of data protection – redundancy, this technique makes a mirror copy of the desk that you wish to keep protected. Data availability is of prime importance and is made sure in case of failure of one drive and data controller serves from the copy disk. However, mirroring reduces the performance, read throughput is enhanced as either disk can be read from while the write speed remains the same as for single disk storage. With RAID 1 you’ll entail minimum 2 drives for duplexing, with the accessible capacity of only 50 percent.
3. RAID 5 & 6
The most prevalent option among video editors is an amalgamation of both speeds of RAID 0 and data protection of RAID 1 in one configuration. RAID 5 is till date the most common RAID configuration relied on throughout businesses and NAS devices. This level operates parity with striping for a low-cost reliable resolution for data protection, using a supplementary disk to the stripe width that’ll hold parity bit to redevise the data automatically in case of failure.
4. RAID 50 and 60:
RAID 50 (or more precisely known as RAID 5+0) associates the dispersed parity of RAID 5 with the striping of RAID 0. Even though overall read and write speeds are reliant on a number of other factors, RAID 50 typically offers faster write speeds than RAID 5 by itself. Though, it comes with a higher price. RAID 50 necessitates at least six drives. Also, with an increase in the number of drives in the RAID 5 array, there is an increased chance of data loss if two or more drives fail simultaneously. In RAID 50, you can endure multiple drive failure, as long as the failed drives occur in the right places. RAID 60 (also more accurately known as RAID 6+0) syndicates RAID 6 and RAID 0. RAID 60 involves at least eight drives.
You can organize your own RAID array by using software, but an array with a hardware RAID controller will deliver improved performance. Also, you should try to opt for hard drives with the same size, speed, and even model so your RAID array can offer optimal performance.
