Dell 5430 Gen4 Nvme
Hello, I bought Dell 5430, . The laptop is fine, everything is updated - bios, drivers. What I understood supports Gen 4x4 NVME and i bought Lexar NM790 1 tb but the speed is half than expected. Anyone with solution for this problem. Thanks

If you look at the manual I linked below, Dell offers different motherboard options depending on customers configurations. I suspect that you have the board with storage option up to Gen 3 based on your original storage selection.

Not all storage in Latitude 5430 are configured with Gen 4, some configurations are with interface of Gen 3. See storage specifications https://www.dell.com/support/manuals/en-us/latitude-5430-laptop/latitude_5430_ss/storage?guid=guid-d86e950c-766f-4153-8836-62da6b2ea296&lang=en-us

What was the original SSD your system shipped with?

The Dell 5430 Gen4 laptop is compatible with NVMe drives, which offer faster data transfer speeds compared to traditional SATA drives. This means you can experience quicker boot times, faster file transfers, and improved overall performance when using NVMe storage.

I understand your frustration with the slower than expected NVMe speeds on your Dell 5430. Here are some troubleshooting steps:
Here's hoping this helps you achieve the expected speeds from your NVMe drive!
