Pardon, but this is idiotic, since the HDDs and SSDs with the longest power on hours and minimal number of errors are already discontinued, if you want to buy a new drive. Your statistic at best is useful to find out what HDDs and SSDs fail much to early, but than consider to care about the usage. Some people turn their computers on and off several times a day, this isn't good for a HDD, while others have got uptimes of more than a year. Other people are maintaining SSDs with kid gloves, OTOH other are using SSDs in the same way, as they use/d HDDs. btw. I'm using my SSDs without kid gloves and when I wanted to order additional SSDs of the same kind, I couldn't get them anymore, let alone the best HDDs I every used.
