The IBM® 128 GB and 256 GB solid-state drives (SSDs) employ cost-effective MLC NAND technology to 

bring an affordable and performance-driven solution for read-intensive applications. The new SSD drives 
will each be available in a 2.5-inch SFF with both simple-swap and hot-swap options. These SSDs use a 
single-chip controller with a SATA interface on the system side and 

n

-channels of Micron NAND Flash 

internally. Packaged in an HDD replacement enclosure, these SSDs integrate easily in existing storage 
infrastructures.

Did you know

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.
