Samsung SSD 840: Endurance Destruct Test

When you operate a Datacenter with many servers you also probably have big number of installed disks. In most cases even you have cluster, especialy in small companies, there is still SPOF (Single point of failure) somewhere.

In this SPOF it's critical to know condition of the system. When system using HDD it's important to know HDD condition to prevent failures, plan maintenance etc.

We will talk about Samsung SSD 840 PRO series. We realize this SSD has very good performance and lifetime. Before we use it in production we must know how to monitor condition. There is many articles and technical specification but we had a lot of questions without answer.
