Is an upgrade worth it? and to what?

I've currently got a DW81KD, with firmware version "V3.5.37 build 190330"

It's serving well, and has done for many years now. But as the HDD is now in dire need for replacement, I'm wondering if it's worth replacing the whole DVR with a new unit.

The problem is, I can't seem to find any reasonable specifications or comparisons to know if I'm missing out on anything worth going for, or which systems support what I want/need.

I'm currently running 4 analogue cameras at 1920x1080 (I don't recall the model number) which are all working well and I'm happy with their quality. I'm also considering adding a new IP camera in an outbuilding (it has an ethernet connection to the building, but not feasible to run a coax cable to it.)

Are there any resources which compare the various DVRs, or are there spec sheets available somewhere that I've not yet found? Preferably including the version I've currently got.

Many thanks
