USB3.x PCI-Express cards in 2022?

I just discovered the rear ports on the N54L can sustain a higher transfer rate than the front ports. They're all listed as USB2.0 so something else is going on here.

 

Anyway, I get decent enough performance (2.6MB/s) ripping CDs through the back ports compared to the (1.0MB/s) of the front ports.

 

All this to say that I can do without USB3 for now.

Hey Guys, 

I'm trying do the same Mod with my N54L. It is an old device if we can let it be performed some high-level performance. 

I have success install the DS2622++ DSM 7.1 on my N54L. There was 4 * 3T disk could be identify. I have few old SSD stick in my hand. I just wonder the N54L will not support for the PCIE splitting, But I found a card can support with one NGFF(Sata) & one NVME SSD. but the NGFF need connect with the 5th Sata port from mainboard.  

The card still on the way, I have another 2.5-inch SSD tray to be SSD cache for the raid. But I am facing the challenge is the 5th Disk cannot be identified in DSM. It is show connected in BIOS already. I also have flashed the MOD BIOS can show the south bridge setting in BIOS, But the 5th disk show in BIOS is the third Primary disk show in BIOS. 

I try to change the DSM Hard disk parameter, whatever for  

DiskIdxMap=0
SataPortMap=8

or 

DiskIdxMap=0000
SataPortMap=42

It still could not be found in DSM. Can any someone help to share the Hard disk parameter with me? or I need do some change in BIOS?

...Any suggestions for a self-powered, low-profile PCI-E USB3.x card for my N54L....

I had once a N54L with a working USB 3 card.

 

Please check my postings if there is any pictures from it. There was an issue with the forum as far as I remember. Probably all Data was deleted.

 

I will check if I can find some pictures from that card if you still need it.
