ENTERPRISE SOLID-STATE DRIVES
Endurance Through Innovation
The s841 SSD combines commercial-grade MLC NAND
flash memory, advanced endurance management firmware
and power loss data management techniques to extend
reliability, endurance and sustained performance over the
life of the SSD. With an MTBF rating of 2M hours, the 2TB
model can endure an impressive 25PB of random writes
over the life of the drive. HGST’s innovative CellCare™
technology is key to the s841 endurance success and
extends the life of flash media to deliver enterprise-class
endurance through advanced signal processing and
adaptive flash management algorithms.
For complete data protection and reliability, the s841
incorporates extended error correction code (ECC), Secure
Array of Flash Elements™ (SAFE) technology to protect
against flash die failure and an exclusive power loss data
management feature using super capacitors. The s841 is
also backed by a five-year limited warranty or the maximum
petabytes (PB) written (based on capacity).
Performance and Capacity for
the Data Center
Accelerating access to data is a proven success formula for
enterprises and service providers worldwide.
The s841 SAS SSDs from HGST are engineered to take
performance to new levels in the data center and eliminate
data access bottlenecks. The s841 delivers up to a massive
industry-leading 2TB capacity, ideally suited for read-
intensive applications, and also offers capacities for today’s
sweet-spot, 800GB and 400GB. With sustained IOPs of up
to 83,200 read and 30,800 write, and maximum sequential
throughput of 525MB/s read and 395MB/s write, the s841
SSD enables rapid access to “hot” enterprise data for
improved productivity and operational efficiency.
HGST Quality and Service
HGST’s s841 family extends the company’s long-standing
tradition of performance and reliability leadership. A
balanced combination of new and proven technologies
enables high reliability and availability to customer data.
