Solid-state drives have more than 100 times better IOPS performance & lower access latency with significantly reduced power consumption compared to traditional spinning hard disk drives. Entry MLC SSDs & Enterprise MLC SSDs have similar read & 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 dem&, data warehouse, content delivery, & other read-intensive random workloads. Providing that additional peace of mind, IBM 128 GB & 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&174; server, . ..
