Solid-state drives have more than 100 times better IOPS performance and lower access latency with significantly reduced power consumption compared to traditional spinning hard disk drives. Entry MLC SSDs and Enterprise MLC SSDs have similar read and write IOPS performance, but the key difference between them is their endurance (or life time) (that is, how long they can perform write operations because SSDs have a finite number of program/erase (P/E) cycles). Entry SSDs have a better $/IOPS ratio but lower endurance compared to Enterprise SSDs. Because of that, Entry SSDs are ideal for web serving, video on demand, data warehouse, content delivery, and other read-intensive random workloads. Providing that additional peace of mind, IBM 128 GB and 256 GB MLC SSDs are covered under IBM warranty. These drives carry a 1-year limited warranty, or when installed in an IBM System x® server, these drives assume your system's base warranty.
