Expansion adapters - Enquiries - 09-13-2022
I actually just wanted to comment about the new 10g nvme cards that Qnap has, it's really hard to find any information about them besides from qnap themselves and I really enjoy the breakdown of the nest compares YouTube videos. I was wondering if you have any plans on doing the QM2-2P10G1TB or the QM2-2P410G1T as they are PCIe gen 3 and 4 which will fix some of the bottleneck issues with the QM2-2P10G1TA. I would love to see some benchmarks ?
Thank, Chad

qm2-2p10g1ta - Gen2 x 2
QM2-2P10G1TB - Gen3 x8
QM2-2P410G1T -Gen4 x8
Qnap will phase old cards out. They are backwards compatible. So if you do get a newer card it will work in older systems.
Here is an expected performance
SPEC X1 X2 X4 X8 X16
PCIe 1.x (2.5 GT/s) 500 MB/s 1 GB/s 2GB/s 4GB/s 8GB/s
PCIe 2.x (5.0 GT/s) 1GB/s 2GB/s 4GB/s 8GB/s 16GB/s
PCIe 3.x (8.0 GT/s) 2GB/s 4GB/s 8GB/s 16GB/s 32GB/s
PCIe 4.x (16 GT/s) 4GB/s 8GB/s 16GB/s 32GB/s 64GB/s
PCIe 5.x (32 GT/s) 8GB/s 16GB/s 32GB/s 64GB/s 128GB/s
PCIe 6.x (64 GT/s) 16GB/s 32GB/s 64GB/s 128GB/s 256GB/s
