QNAP QM2-2P2G2T2 x PCIe Gen3 M.2 NVMe SSD & 2 x 2.5GbE Port Expansion Card to Enhance Performance

If you're locked into the QNAP ecosystem, you don't really have a choice about the cost, but it does show up occasionally for less if you can afford to wait. That said, it has worked flawlessly for me over the past several months. So it's a great product that simply takes a chunk out of the wallet.

Gives you 2 x m.2 slots, heatsinks, a fan and 2x 2.5gb ports for not much more cost than one of those items by themselves. I added this to my compatible qnap Nas and I am using both ports (SMB 3.0) and both drives for caching. I deducted a star because the fan is loud when it goes to full speed, which can be pretty often if the unit is under load. Overall I am impressed with the versatility and performance.

I purchased this card for my QNAP TS-653D NAS to replace the original two 2.5G ports, which I found their connections are not reliable. They sometime disconnect with no apparent reason and some time dropped down to 1G.. The worst thing is, their connection may come on for a few second and off for a few second. They are both connected to the QNAP QSW-2104-2T switch. So the problem may be the QNAP NAS or the QNAP switch. I bought and install this card hoping I can by pass the problem, but found the situation does not improve. The only improvement is their connection speed never drop down to 1G. I can only conclude that this card is okay. The problem is still the NAS or the switch.

First one had a defect. The thermal pad was dented all the way through. The second was filthy and sealed with regular tape. The third was missing thermal pads. Although the seal was secure this time. Sign...close to giving up on Amazon and qnap. Amazon with it's shipping used products and qnap with the low quality overall..
