I bought this not knowing how close the next 8- Bay was in the price. If you upgrade to TS-873-4G-US (or other iterations), you'll pay less than $200 ($731 vs. $900) and get: AMD x86-64-based CPU vs. ARM- Chip in this device - 2 ports 10G BaseT Ethernet (This has SFP+ ports that only need modules for copper). Ironically, buying two of them can make up the difference in cost. - 4 x RAM supported (64GB vs. 16GB) - HDMI output - Ability to add GeForce GT1030 for HDMI output and extra transcoding performance - Two M.2 SATA input slots in addition to the ability to add multiple PCIe cards with M. 2 to add for each model. Wow - after looking at it I'm about to swap mine out, but I've already started backing up and signed a support contract. I think I'll keep mine and get a TS873 or better next time. I save the dates so it happens sooner than I want.
