00AJ370 (Lenovo / Hard Drive – Internal (Enterprise))
The Lenovo 120 GB, 240 GB, 480 GB, and 800 GB solid-state drives (SSDs) are next-generation Enterprise Value SSDs for System x that are engineered for greater performance and endurance in a cost-effective design, and to support a broader set of workloads. These SSDs are available as 2.5-inch form factor drives with both simple-swap (SS) and hot-swap (HS) options, as well as 3.5-inch hot-swap and 1.8-inch drives.
The Lenovo Serial Advanced Technology Attachment (SATA) MLC Enterprise Value SSDs have the following features:
Enterprise Value SSDs and Enterprise SSDs have similar read and write IOPS performance, but the key difference between them is their endurance (or lifetime) (that is, how long they can perform write operations because SSDs have a finite number of program/erase (P/E) cycles). Enterprise Value SSDs have a better cost/IOPS ratio but lower endurance compared to Enterprise SSDs. SSD write endurance is typically measured by the number of program/erase (P/E) cycles that the drive incurs over its lifetime, listed as the total bytes of written data (TBW) in the device specification.
