The Synology RS4021XS+ is powered by a 2.1 GHz Intel Xeon D-1541 Eight-Core processor, which will allow you to run multiple functions simultaneously. The built-in 16GB of DDR4 ECC RAM, which comes in a 1 x 16GB configuration, will allow quick access to frequently used files and programs and may also be upgraded to a total of 64GB by using a 16GB module in each of the four 288-pin DIMM slots. Also featured are two USB 3.2 Gen 1 Type-A ports, which allow it to be connected to external peripherals. Network connectivity is achieved via the two 10 Gigabit Ethernet or four Gigabit Ethernet ports with failover support, which help to provide redundancy in the case that a LAN connection malfunction occurs on one port.
