RAID 10: A partnership between RAID 1 and RAID 0

Balancing the need for performance and reliability within a RAID system.

The RAID 0 system is known for bringing performance in data processing, but at the expense of security. On the contrary, RAID 1 makes it possible to secure the data, but does not generate any performance gain. RAID 10 is therefore an excellent compromise between the two types.

Read below to get a better understanding on how it works and its various advantages. We will also compare it with another type of configuration, RAID 5, which is widely used in servers.

RAID 10: A powerful and reassuring combination

To understand the configuration of the RAID 10, it is important to study both the RAID 1 and RAID 0 that compose it. Firstly, RAID 1 is a set of two hard drives, one of which is mirrored to secure the stored data. This cloning system has a high fault tolerance and is therefore suitable for storing sensitive data. RAID 0 is a system that distributes information stored on multiple hard drives by interweaving data, meaning the access time is accelerated.

RAID 10, also known as RAID 1 + 0, consists of assembling two or more RAID 1 devices into a RAID 0 array. For example, two hard drives are assembled in RAID 1, two other hard drives are assembled identically, and so on. It requires a minimum of four disks and always in even numbers. An assembled cluster forms a logical unit that will be associated with other clusters to allow interweaving as is the case of a RAID 0 system. The redundancy of data in each sub unit ensures their security, while that the distribution of the data on several logical units accelerates the reading and the writing.

There is the reverse which is called RAID 01, the fault tolerance is less important, since a faulty RAID 0 subset impacts the entire performance.

We'll collect your device and perform an evaluation, free of charge.

Data recovery for single drives and smartphones starts from £478.80 (inclusive of VAT). The final price will be determined at the end of the evaluation, according to the complexity of the work involved and the urgency required.

To begin, start by clicking on the type of media from which you need data recovered. The evaluation time for single hard drives (HDD and SSD) is four hours*, and within 24 hours for RAID systems*. Other media, such as mobile phones do not require an evaluation to provide an accurate quotation.

*These are typical time frames and apply within normal business hours (Monday to Friday, 9am to 5pm). For an out of hours, emergency service, or for further assistance, please contact us on +44 (0)1372 741999.
