You haven't mentioned what amount of storage you require other than to say you'd like 5 bays
But if you don't need much space, the
QNAP TBS-453A is an Intel N3150 Celeron quad core machine featuring up to 16GB of DDR3L RAM, 4x M.2 6GB SATA SSD slots with RAID 0 1 or 5 support, a 5x Gb etehrnet hub, IR remote and dual 4K HDMI outputs all in a rather small 25x230x165mm box that can sit nicely under your TV
I know for many it's not the prefered option to have an all in one KODI/NAS box but with TB sized M.2 SSD's you'd have around 4TB of redundant storage available (which is not shabby)
And who knows how big these M.2 SATA SSD's will become in the next few years though 4TB M.2 SSD's aren't out of the question
Only unknown for me is if the box supports both SATA and PCIe based M.2 sticks since the PCIe M.2 (NVMe?) standard may take over from the older? SATA M.2 based sticks
If this box provides raid level migration/expansion, it may allow a reletively simple size increase by replacing the M.2 sticks one at a time
But if not, you can always hook the bigger QNAP USB3 NAS boxes with their spinning rust if needed
Not meaning to hijack the thread but curious what others think about such small combined KODI/SSD NAS box as compared to older styled HDD based NAS boxes

Sorry i saw that you are looking at 5TB or 6TB drives in a new NAS (giving maybe 30TB) so the M.2 SSD box (even at 16TB with non existant 4TB M.2 sticks) is useless to you
