Samsung SSDs are good. However, with any SSD when they fail, it’s quite out of the blue. With older platter drives, the internal mechanisms often make some sort of noise that can alert you.
I will say this: I would stay away from Seagate drives nowadays. They lost their way somehow over the past 10 years and I wouldn’t use them for anything critical now. Western Digital, who was long the second choice, makes excellent internal and external drives.
I would avoid the MyCloud products. A WD Passport drive is a good choice IMHO and experience.
