The Supermicro SATA DOM (Disk on Module), the SuperDOM, is a small SATA3(6Gb/s) NAND flash memory module designed to be conveniently inserted into aserverboard SATA connector to provide high performance solid state drive storage(SSD) capacity. SSDs are different in how they wear in comparison to hard diskdrives (HDDs). Due to the characteristics of NAND flash, SSDs have a finite lifetimedictated by the number of write operations known as program/erase (P/E) cyclesthe NAND flash can endure. The objective of SSD endurance measures is to capturethis consumable nature of flash storage into quantifiable numbers to provideend users with guidance on the anticipated lifespans for the drives in operation.SSDs come in a variety of endurance points matched against their intended workpatterns. Obviously, SSDs intended for a single user such as a consumer will differgreatly from data center-grade SSDs that are rated to withstand the demands ofthousands or millions of users. It’s important to procure the right SSD for yourworkload and budget needs.
