Features & Beneꢀits
Feature / Function
Beneꢀits
Serial Attached SCSI (SAS) interface in a 2.5-inch form factor Industry’s gold standard for enterprise performance SSDs supporting servers and tier-0 storage applications
High performance
Random transactional performance exceeds 85,000 sustained IOPS, with sustained random or sequential large block transfers up to 530MB/s
Power/performance efficiency
A single s842 SAS SSD replaces large numbers of enterprise HDDs while delivering superior performance and data persistence, instant backup and recovery in the event of
an unplanned power failure
Secure Array of Flash Elements™ (SAFE) technology
CellCare® technology
Provides the ability to recover from NAND Flash page, block, die and chip failures, and maximizes the Mean Time Between Failure (MTBF) and Mean Time To Data Loss (MTTDL)
Extends the life of Flash media to delier enterprise-class endurance through advanced signal processing and adaptive Flash management algorithms

One gigabyte (GB) is equal to one billion bytes, one terabyte (TB) is equal to 1,000GB (one trillion bytes), and
one petabyte (PB) is equal to 1,000TB (one quadrillion bytes) when referring to solid-state drive or hard drive
capacity. Accessible capacity will vary from the stated capacity due to formatting and partitioning of the drive,
the computer’s operating system, and other factors.

MTBF and AFR targets are based on a sample population and are estimated by statistical measurements and
acceleration algorithms under median operating conditions. MTBF and AFR ratings do not predict an individual
drive’s reliability and do not constitute a warranty.
