However, everyone that I have encountered that has had a 2-bay NAS always regrets not getting a 4-bay. Storage pools can be changed from one RAID type to another without losing existing data.īest RAID Solution for web-hosting? RAID 1 is the best solution if you are using your Synology NAS as a web server for self hosting a website (or more).I have previously covered 2-bay NAS drives, which are great for keeping things as affordable as possible. This type of RAID will slow down your hosting server a little if you are using your Synology NAS for web hosting like I am, but should make it more secure and so much safer in case of disk damage, giving you a good chance at data recovery.Ĭan I change my RAID type after I have already set one? A RAID type can only be changed by adding one or more disks to the setup. RAID 1 is the best option: Writes identical data to both drives simultaneously and provides data redundancy. For example, if I were to have my entire web hosting system on a single drive, I couldn’t afford to lose the disk because I would lose all the data without any means of recovering it. Don’t put data on a single disk unless you can afford to lose it. You need a backup strategy.Īvoid RAID 0 or Single Disk SHR: Data on a single disk that is not mirrored is vulnerable.

Don’t confuse resilience with a backup archive – they are very different thins. But if data is accidentally deleted or modified, those changes are mirrored too. RAID is NOT a backup: RAID provides dynamic resilience so that your system can continue to run if a drive fails, by falling back on the other disks in the RAID system. Note that a RAID volume (either Classic RAID or SHR) is not a backup system. SHR allows for 1-disk or 2-disk worth of redundancy – meaning the SHR volume can suffer up to two disks lost, and the data volume will still be available for use. SHR will allow users to handle RAID management, expand storage and maximize storage capability and meet the needs of new users who are unfamiliar with RAID types. Synology SHR is an automated RAID management system that makes storage volume deployment easier than traditional RAID systems. 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 case, 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 for it.

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 manual RAID levels may be available on your Synology NAS: 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 a drive fails, the system is able to keep operating, using the remaining drive(s) while you organize a disk swap. 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 for your HDD or SSD disks based on your needs.
