In 2021 I bought at least ten 870 EVO 4 TB SATA and six 980 Pro 2 TB NVMe. All devices failed within 6 months on barely used systems. Find some smart data here:

The pattern is always the same: I have them configured in a raid 1. Once a month debian does a raid check. During the raid check Debian reads all data from both devices. I get uncorrectable read errors. I no longer use Samsung SSDs and replaced them them with SSDSC2KB076T8, Micron SSDs and KC3000 Kingston NVMes. No failures since then. In 2021 I told a friend of mine about the issue. He also had a 870 EVO, issued a dd if=/dev/sdX of=/dev/null bs=8M and guess what, he got uncorrectable read errors. Due to running them in RAID 1 I caught the issue early and I had no data loss or downtime because the Linux software raid compensated for the bad hardware. However I replaced them in a hurry because I no longer trust Samsung SSDs. As you can see from the smart log they're barely used. Less than 4 months in service and 10 TB written. I also got uncorrectable read errors when evacuating data from the devices.

Similar experience for me. Four 2TB 980pro in RAID-Z2. Since introducing the drives in August 2021 I've had to replace them five times. I think none of the original SSDs are left. Only between 5 - 25TB written on average. Usually individual uncorrectable errors caught by ZFS, but one drive just straight up died. I keep a cold spare these days. On the bright side, if the cycle continues, I'll never run out of warranty from Samsung or the vendor.

The warranty is from the date of sale of the original unit. Replacing one doesn't reset the warranty end date.

If this really becomes an issue due to repeated failure, lemon law activates for a refund.

I tested mine. 980 (non-Pro) 1TB with ~20TB read and ~13TB of written. No errors logged. SMART looks fine. No errors when issuing dd as suggested. Though sometimes I do get weird errors put I will put the blame on AMDGPU drivers and the mess that Gnome on Arch often is.
