Improvement Lap Top Performance: HP model 15-db003

[CChamp2022]

Hello,

I have a HP laptop 15-db003ca that I have purchase a few years back.  Since the moment I have bought it, I'm unsatisfied with the performance of the product. It is so slow....

I have read the comment of an expert, in January 2022,  on this forum.  Someone wanted to switch the hard drive for a 500GB SSD.  The expert replied that it was a good idea but  the laptop also have a M.2 slot that could a NVMe SSD and it would be faster than SATA SSD.

Here's my question:

1. I understand that the NVMe SSD is faster than a 500GB SSD.  Does it mean that I would keep the hard drive with 1TB in place and I would add the NVMe SSD in the open M.2. slot?

2.  It seems there are physically different sizes of NVMe SSD.  Which one fits for the HP laptop 15-db003ca?

3. What would be the recommendation for the minimal storage space to be satisfied?  

Thank you for your help

Here is the Service Manual:

Page 42 has a good image of the M.2 slot next to the battery. Yes, you would want to keep your 1 TB 5400 rpm mechanical hard drive as storage and add an NVME M.2 SSD 2280 form factor as the boot drive. With 1 TB of storage you could get by with a 256 gig SSD but I recommend at least a 512 gig.

This is a good one and you have options to buy different sizes:

This is what I have in my own laptop:

Potentially somewhat faster than the Crucial. 

Post back if you need any more help.
