Synology's DiskStation DS1520+ is a 5-bay NAS designed for small offices and IT enthusiasts featuring a pair of M.2 NVMe slots for SSD caching and four Gigabit Ethernet ports.

Powered by an Intel Celeron J4125 quad-core processor clocked at 2.0GHz (burst up to 2.7GHz) the DiskStation DS1520+ comes with 8GB of DDR4-2666MHz memory which is the most the motherboard supports. It also supports an AES-NI hardware encryption engine.

Synology quote Sequential throughput performance for the D1520+ as up to 451.28MB/s for reads and 451.18MB/s for writes although those figures are from the NAS being tested with all four LAN ports being used in Link Aggregation mode.
