  Hello,

  As my secondary SSD, I recently bought a SABRENT 2TB Rocket 4 Plus NVMe Gen4 (SB-RKT4P-2TB).

  I have Sabrent Rocket 500GB as the primary drive. Here are its benchmark results and the results are totally fine.

  

  Below are the results of my SABRENT 2TB Rocket 4 Plus NVMe, I wonder why the read speed is around 3000 MB/s. It should go around 6000 MB/s, right?

  

  

  What could be the reason for this? My motherboard is a TUF GAMING B550M-PLUS (WI-FI) with PCIe Gen4 x 2 slots.

  @Prabath Gamage Hi. It looks like your motherboard's second M.2 slot is only x4 PCIe 3.0. These speeds are normal for that. You'd have to put the Rocket 4 Plus in the first slot to get full speeds, although the original Rocket 4 you have in the second slot would then be capped.

  @Sabrent thank you for the explanation. I just noticed that the other slot is PCIe 3.0 :)
