I've gone through three Samsung EVO sdcards in an Intel NUC. I was using it as a boot drive. All were replaced under warranty. But they each died, becoming read-only, within about 5 months of use. I don't think these cards are designed as random access devices. I think they're for cameras: video and photos, and also for cell phones, also mostly video and photos, maybe some app offloading also.
