Qnap TVS- x72XT series with 40GbE NIC

pcie slot advice on the qnap tvs-872xt

Message Body:
PCIe Slot that is available not compatible with 40Gbe cards

-so what speed are the tb ports on this device?

-Are pcie cards that will give me 40gbe speeds?

– to get tiered storage with ssd , what configuration will you recommend?- or would you simply populate with a couple of nvme drives.

– also another question , as qnap doesn’t support hybrid drives, what happens if you cannot replace a drive with the exact same model, does that mean your have to start from afresh with a raid setup?

– whats the top speed you can get with the standard tb3 ports

– if i get additional qnap pcie(can i use 3rd party) what are the top speeds i can achieve.

The Qnap 72XT series are compatible with 40GbE card LAN-40G2SF-MLX. But if you want to install it you need to remove Thunderbolt card which is capable of 40GbE bandwidth too. But you would get two ports instead of one.

The 40GbE speed will very much depend on the media you will use. Qnap have tested RAID 5; 8 x SSDSC2BB240G4 SSD and achieved 1230 MB/s, but you might get even better speeds with dual NVME M.2 SSD installed.

For the best tiered storage solution I would recommend couple of NVME + SSD + HDD drives.

When you run out of storage space, you don’t need to replace all disks and reset the system. You can attach expansion unit and gain extra storage space this way. Or you can replace existing drives one by one without resetting the NAS.

You can use also third party cards. As long as you match or get older version card for a PCIe slot – it will work.
