DSM Specifications
Storage Management		Maximum Single Volume Size*		108 TB
		Maximum Internal Volume Number		64
		M.2 SSD Storage Pool Support*		Yes
		SSD Read Write Cache (White Paper)		Yes
		SSD TRIM		Yes
		Supported RAID Type		Synology Hybrid RAID Basic JBOD RAID 0 RAID 1 RAID 5 RAID 6 RAID 10
		RAID Migration		Basic to RAID 1 Basic to RAID 5 RAID 1 to RAID 5 RAID 5 to RAID 6
		Volume Expansion with Larger HDDs		Synology Hybrid RAID RAID 1 RAID 5 RAID 6 RAID 10
		Volume Expansion by Adding a HDD		Synology Hybrid RAID JBOD RAID 5 RAID 6 (with Expansion Unit)
		Global Hot Spare Supported RAID Type		Synology Hybrid RAID RAID 1 RAID 5 RAID 6 (with Expansion Unit) RAID 10 (with Expansion Unit)
		Notes		Usable capacity for each volume will be lower than the maximum volume size and is dependent on the filesystem and the amount of system metadata stored. Creating M.2 storage pools requires the use of Synology-verified SSDs, which are rigorously tested under extreme temperature conditions. Thermal parameters for SSDs and NAS units are fine-tuned to ensure optimal management of thermal conditions under I O-intensive environments. (Learn more) Actual maximum storage pool and volume sizes depend on drive sizes used, the number of drive bays available, and the RAID configuration. Each internal volume (may consist of multiple drives) is expandable up to 108TB.
