![]() ![]() Synology SHR is an automated RAID management system that makes storage volume deployment easier than traditional RAID systems. It provides data redundancy if the volume is composed of two or more drives. SHR optimizes volume size when combining drives of different sizes.If you don’t have the technical expertise to differentiate between the different RAID types to suit your use, Synology has you covered with Synology Hybrid Raid ( SHR): RAID F1 Implements block-level striping with parity data distributed across all member drives. Writes more parity information on a certain drive. Recommended for an all-flash array.RAID 10Provides the performance of RAID 0 and data protection level of RAID 1, combining drives into groups of two in which data is mirrored, but you need a minimum of 4 disks.RAID 6Implements two layers of data parity to store redundant data equal to the size of two drives, providing a greater degree of data redundancy than RAID 5, but you need a minimum of 4 disks.RAID 5 Implements block-level striping with parity data distributed across all member drives, thus providing data redundancy more efficiently than RAID 1, but you need a minimum of 3 disks.RAID 1Writes identical data to both drives simultaneously and provides data redundancy.RAID 0 Features “striping,” a process of dividing data into blocks and spreading the data blocks across several drives in order to enhance performance.JBOD Combines a collection of drives into a single storage space, with capacity equal to the sum of all drives’ capacity.BasicComposed of one drive as an independent unit.The following RAID levels may be available on your Synology NAS You can quickly and easily choose different RAID types and, at the end, you will even be shown a recommended product. Once you access the Synology website via the link above, you will find yourself in front of this extremely well-organized tool where you will be asked to choose the number of disks and their capacity. The data storage virtualization technology combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both. If one drive fails, the system is able to keep operating, using the remaining drive(s) while you organize a disk swap. For those who don’t know, RAID is the acronym for Redundant Array of Inexpensive Disks, the purpose of which is to give you varying degrees of resilience by copying/spreading the data from a disk to one or more other disks. If you have a Synology NAS, you can choose a different RAID type on your HDD or SSD disks. Did you know that Synology offers a free tool named RAID Calculator? Synology’s RAID Calculator tool can provide an estimate on space utilization with various mixed HDD/SSD configurations and RAID types. ![]()
