Slow NVMe performance on Aspire 5 A515-43-R19L. Limited to 2 lanes?

Hello,

Replaced stock NVMe drive on the laptop with a Samsung 980 500GB and performance is roughly half of the published specs.

Took a look with CrystalDiskInfo and it shows the current transfer mode as PCIe 3.0 x 2 instead of the drives maximum 3.0 x 4 supported mode.

Is this model laptop limited to only 2 NVMe lanes?

Thank you in advance for any information on this!

Hi,

Yes, unfortunately, most everyday laptops are limited to PCIe 2 lanes in order to reduce heat.
