Abstract:
Systems, apparatuses and methods may provide technology for intelligent drive wear management. The technology may include determining a difference between a wear value derived for a first solid state storage drive and a wear value derived for a second solid state storage drive, and if the difference in wear value exceeds a wear skew threshold, swapping content between the first drive and the second drive. The technology may also include sorting an array of solid state storage drives into a plurality of drive groups based on a wear value derived for each drive, and determining, for a first pair of drives in a drive group, a difference in wear value between the drives in the first pair. Respective pairs of drives in a drive group may be selected based on the drive wear value and a drive rotation counter value associated with each drive. The technology may further include determining an average wear value for each drive group based on the wear values of each drive in the drive group and providing for maintenance service for the drives in the drive group if the average wear value for the drive group exceeds a potential drive failure threshold.
