I knew that upgrading from an SSD like a Samsung 850 EVO or 860 EVO would be drastically faster, but if you like synthetic benchmarks, it's hard to "hdparm -tT --direct /dev/nvme0n1" on a Linux box and NOT have your eyeballs bug out of your head with this card! It was over 2 Gigabytes per second on reads which is probably way more than you can ever realistically use on a home system (especially if you're not doing AV production or similar.) That said, Samsung makes darned fine product and the warranty, the performance, and the solid Samsung firmware updates all clinch the deal. I'm sure a 970 EVO might be faster, but a refurb'd Geek Squad 960 EVO sure made me happy. Finally, make sure you buy a PCIe sled that's NVMe compatible if this isn't going into a newer mobo or laptop. I planned ahead and the installation was flawless.
