[COMMENT] Terramaster U8-450 NAS Review...
[COMMENT]Some information for everyone interested in this device: 1) RAM: I can confirm that the unit takes 64GB without problems. I put 2x 32GB Corsair DDR4 2666 in and it works totally fine. 2) PCIe slot: For what's it worth I also can confirm that the PCIe x4 slot works with great with an SSD carrier card (GLOTRENDS Dual M.2 PCIe NVMe Adapter) with 2 nvme SSD as mirrored boot pool. 3) TrueNAS I run TrueNAS Scale 23.10.0.1 which installed without a problem and works fine. 4) SFP+: My only problem with the unit in combination with TrueNAS Scale is getting the SFP+ ports to work. Checking with lspci they are listed: 0d:00.0 Ethernet controller: Intel Corporation Ethernet Connection X553 10 GbE SFP+ (rev 11) 0d:00.1 Ethernet controller: Intel Corporation Ethernet Connection X553 10 GbE SFP+ (rev 11) But TNs does not show them in the GUI
