The PNY CS2241 M.2 NVMe Gen4 x4 SSD has been an excellent choice for an upgrade in an NVMe Gen4-enabled laptop computer. I have found boot up, power down, and load applications to be considerably faster compared to factory supplied SSD in my ASUS TUF Gaming Laptop. Although I initially purchased the SSD device for its 4TB capacity.

Good value for money, but slow on sustained writes

I bought two of them, to use them in RAID 0 or RAID 1 configuration in a thunderbolt enclosure. When I'm running benchmarks, or copying small files, they're reaching between 2.4GB/s and 2.8GB/s, which is expected for this enclosure. I also have the same enclosure with 2x 2TB Seagate Firecuda 510 SSDs, which are reaching slightly over 3GB/s on read/write. However when I'm doing a sustained write, like backing up a VMWare Virtual Machine for example, the speed drops down to about 70MB/sec, while the Seagate SSDs for example maintain about 1.2GB/sec for the same task. I know the Seagate SSDs did cost twice as much when I bought them a couple of years ago, but keep that in mind if you're intending to do sustained data writing to them. I'd opt to a different SSD for such ... MoreI bought two of them, to use them in RAID 0 or RAID 1 configuration in a thunderbolt enclosure.
