Offered in MLC capacities of
300GB and 600GB, the XE SSDs support latency responses up to 50 microseconds
and have a 6Gbit serial-attached SCSI (SAS) interface. From a performance
perspective, both the 300GB and 600GB capacity drives support up to 500MB per second
(sustained read throughput), up to 275MB per second (sustained write
throughput), up to 115,000 input/output operations per second (IOPS) for read
operations, up to 70,000 IOPS for write operations and 38,000 IOPS for 8K
random read/write operations (70 percent/30 percent).
The XE SSD uses a
combination of STEC's fourth-generation ASIC-based SSD controller and its
proprietary CellCare technology, which when applied to MLC flash, extends the
performance, reliability and endurance capabilities of these drives. As a
result, STEC can fully write about 33 petabytes of data over the working life
of a 600GB drive (a workload of writing the full capacity of the drive 30 times
per day for five years).
"Enterprise networks and
data centers need to develop innovative ways to address the issues caused by
the enormous and growing amount of data being created," said Jeff Janukowicz,
research director for solid-state storage at IDC. "Solid-state solutions, such
as STEC's SSD family with its CellCare technology that improves MLC flash
endurance, enhance MLC SSD performance and reduce media access error rates for
consistent performance over the entire useful life of the drive, and are
increasingly being leveraged to solve these issues and help IT organizations
optimize their storage in a fast, reliably cost-effective manner."
One of the most notable
features of STEC's CellCare technology is its ability to measure and manage the
wear of the drive using adaptive flash management algorithms and advanced
signal processing techniques. As MLC flash will wear out faster over time if
not properly monitored and managed, CellCare technology proactively manages the
way the flash wears throughout the life of the drive. The additional use of
advanced error-correction code (ECC) techniques enables higher protection
against media errors and improves SSD endurance for write-intensive workloads
without limiting the performance of XE SSDs.
To further improve MLC SSD
reliability, XE SSDs incorporate STEC's Secure Array of Flash Elements
(S.A.F.E.) technology that prevents data loss associated with MLC flash. It
also provides the ability to recover from NAND flash page, block, and die and
chip failures while maximizing the mean time between failure (MTBF) and mean
time to data loss (MTTDL).
"Our XE SSD solution is a
direct response to the growing customer demands for ultra-high-endurance
solutions that address high write activities associated with caching and
logging applications," said Scott Stetzer, STEC's vice president of technical
marketing. "We've engineered our new ZeusIOPS XE MLC flash-based drives to
deliver extended enterprise endurance for the demanding write-intensive
applications and provide our OEM customers with a superior choice for a
cost-effective enterprise-class SSD that they can rely on."
