Disappointed in performance of new M.2 SSD on new Dell Ultra PCIe card
Have a new-to-me Dell Precision 5820. Came with a front load M.2 SSD that was acting up and had a bazillion hours on it, so I bought a new Dell Ultra SSD M.2 PCIe x4 card, and a new Crucial P3 Gen 3 NAND SSD. All is installed and functioning normally, HOWEVER, the speeds are just not at all what I was expecting:
Original Inland TN320 SSD I/O speed tests at 350 MB/sec min and 1291 MB/sec max (through the FRONT load SSD slot)
A Samsung MZVLB1T0 SSD I/O speed tests at 1041 MB/sec min and 1400 MB/sec max (also through the FRONT load SSD slot)
The Crucial advertises speeds of up to 3500 MB/sec, but on my system, through the Dell PCIe card it tests at 650 min and 1250 max.
Is there a tweak that needs to be made? The card is in slot 4, which is PCIe x16.

Dell Ultra-Speed PCIe card is a passive adapter and was not a factor of performance, except for active cooling.
The speed issue is very likely affected by the SSD and/or the Intel storage controller. You can try any of the following: restore default BIOS settings, update BIOS firmware, reinstall chipset driver, reinstall RSTe driver.
If use the Ultra-Speed Duo adapter, move it to slot 1.

I have updated, AND then re-installed BIOS firmware, Chipset driver, etc. What would be nice is if there were some documentation somewhere that specifically addressed how to use and setup this card? I can't find anything.
The numbers above show a significant speed advantage for the Crucial drive on the Dell PCIe card - BUT, it just seems strange to me that even so it is only giving basically 1/3 of its rated speed. (I know it will never hit full, ideal, lab condition speeds of 3500)

Interesting new information: I had been using the latest version of HD Tune Pro for my benchmarking. For kicks, I downloaded CrystalDiskMark and tried it - now I consistently get around 3500 MB/s out of the Crucial on the Dell Ultra PCIe card! (And the Samsung on the front load slot is still consistently around 30% slower)

Glad to hear your SSD in Dell Ultra-Speed adapter is working well as expected. You can remove the Samsung from flexbay and installing into the Dell Ultra-Speed for performance testing.
