Get a used asustor or synology box on ebay and get the certified refurbished drives that Seagate sells directly. While you can build your own using zfs like others have mentioned to me the cost savings wasn’t worth it. I use mine for backups I don’t want the most important part of my chain to get fucked up because of something I did or didn’t do properly. I went with asustor which has a ton of one click install apps and brain dead easy backup to another asustor I have set up across country at a family members house.
Unless you are writing petabytes the nvme did not just burn “wear” out. Probably shouldn’t do anything until you figured out what caused this failure
