Instead of trusting DLink with an off the shelf NAS, it might be easier to build your own with a Raspberry Pi running openmediavault hooked up to a couple of USB hard drives. It’s worked well for me for over 6 years now with no issue and could cost way less.
I’d say the PS3 was the pinnacle of console gaming, at least with the early 60GB models. They had full backwards compatibility with PS1 and PS2 discs and DVDs while adding a Blu-ray player and internal hard drive to eliminate the need of memory cards. Access to online multiplayer and PSN was also totally free until MS showed Sony how much they could charge for the next generation of consoles. While it had its fair share of controversies like the initial price tag, PSN hack, and updating the firmware to no longer boot custom Linux OSs, it generally had the most features that any casual fan would enjoy.
