DS1621+ is indeed a faster NAS, but not as multimedia friendly. It would cope with 4K better than DS1520+ while transcoding simply because CPU can convert those videos faster the DS1520+ media chip. But there is a price to pay. While it does transcode, other task performance will be affected.But none of this applies if you have compatible TVs. In that case, you would stream original videos files without the need for on-the-fly conversion.Faster CPU will also allow faster data transfer speeds. Celerons can deliver somewhere below 10GbE speeds (even if one day they released an adapter). Ryzen could easily cope with 10GbE upgrade card if you choose to add it.I hope this helps.
