Yeah I know that these are old drives, we&#x27;ve done this testing about year and a half ago and when we started renting  servers more than 5 years ago, we didn&#x27;t think about which SSDs are in there. At that time we didn&#x27;t have an option to choose, nor time to think about the implications of different SSD models, we used what we got. Later on when we grew and started having problems, we started investigating what models we should use. The main reason for writing this article is for people to be aware that they should test their drives and how to do it.
