What is the brand name and model number of your ssd? What do you do with your pc? Do you use it for professional work or something else?
I am assuming you want an PCIe 3.0 x 4 NVMe ssd with an M.2 connector.
I maintain an ssd database listed in a sticky at the very top of this forum section. Here is the link:

The PCIe 3.0 x 4 NVMe ssd's are listed in the very first section at the top of the ssd database. Look for the ones with M.2 interface / connector. You can follow the links to the technical reviews. The reviews are divided into two sections - English language reviews and reviews in other languages. There are no advertisements or other distractions. It is strictly a hobby.
