Decision guide
Look to the DS925+ for the mix of ECC memory, dual 2.5GbE and expansion beyond four bays.
There is no integrated hardware transcode engine. Bays can grow from four to nine, and memory can go as high as 32GB.
Storage is 4-bay, and 2.5 Gbps is the fastest network path documented.
Extra processing power will not add a bay that isn’t there. Settle the storage layout and expected growth first.
