Important facts about Synology RAID

What is RAID data recovery?

Files, paperworks, and physical records are redundant now. Everything is now saved in the computer as data. Especially in offices and big corporate setups, computers are the only means of data storage. However, storing data in computers does not prevent them from being vulnerable to loss. Data stored in machines is as susceptible to damage as information stored in papers. Hence there have to be measured in place to recover the data that is lost. There are special technologies and tools that have been developedto recover lost data. Once such technology is Synology RAID data recovery.

Synology RAID is the acronym for Redundant Array of Independent Disks. It is a technology designed for data storage. It basically creates a hub that allows various drives to be combined in one storage space. There are different types of RAID and can be categorized based on their storage capacity, reliability, and level of performance. Synology RAID data recoveryworks on the principle where many network attached storages use tools (disk groups and volumes) that are unique in themselves to organize one storage space. Files are stored as volumes while disk groups are an arrangement of hard drives that work as one RAID array.

What are the types of RAID?

There are different types of Synology RAID data recovery supported by Synology NAS. This categorization is done based on storage capacity, the number of required drives, and the number of drive failures that the technology can withstand before data loss happens. Synology RAID data recovery technologyis of the following types, based on their volume:

  • SHR: this type of RAID can have more than four hard drives and can tolerate one to two drive failures before data loss. They have the capacity to optimize the size of the volume when mixing drives of different sizes. Based on the type of volume,the volume capacity can be optimized according to the system.
  • Basic: this type of RAID as the name suggests is not designed for superior function. It has only one hard disk and cannot tolerate any drive failures. They only have one drive that operates as an independent unit and is not capable of providing any data redundancy. Their volume capacity is that of the one hard disk that it has.
  • JBOD: this type of RAID contains more than one hard drive, but is not capable of tolerating even one drive failure. The volume capacity of this type of RAID is the sum of the number of drives that are combined together to form one composite storage unit.
  • RAID 0: this type contains more than two hard drives and the volume capacity is the sum total of the number of hard drives combined together. They have a unique feature called ‘striping’, whereby the data is divided into blocks and these blocks are spread across the different drives to improve performance. However, even this type does not provide data redundancy.

Synology RAID data recovery technologycan be categorized into many types based on their features and each type is designed in a manner that can suit your need.
