Samsung 870 QVO 4TB SATA SSD-s: how are they doing after 4 years of use?
How much damage can a self-hosting enthusiast do to a quartet of Samsung SSD-s after 4 years?
They’re old enough to be popping up on the second-hand market, so I thought it would be good to provide a few additional data points for those thinking about buying one. These drives are still performing at the expected speed and at during write-heavy workloads they only drop down to 140-170 MB/s, which is considerably better than what the cheapest SATA SSD-s can do in the same scenario, those can go a low as 30 MB/s or even worse. For comparison, 4TB SSD-s from other manufacturers and form factors (NVMe, SATA) start from about 190-200 EUR, however I am not fully confident that those perform at the same level, at least under sustained writes.
