Highlights
Endurance Through Innovation
• cMLC NAND Flash for higher ROI while delivering high
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 perꢀormance over the
liꢀe oꢀ the SSD. With an MTBF rating oꢀ 2M hours, the 2TB
model can endure an impressive 25PB oꢀ random writes
over the liꢀe oꢀ the drive. HGST’s innovative CellCare™
technology is key to the s841 endurance success and
extends the liꢀe oꢀ flash media to deliver enterprise-class
endurance through advanced signal processing and
adaptive flash management algorithms.
Accelerating access to data is a proven success ꢀormula ꢀor
enterprises and service providers worldwide.
performance and endurance
• 6Gb/s SAS interface for maximum throughput
• Advanced power loss data management technology
• Outperforms competitive SATA SSDs while delivering
The s841 SAS SSDs ꢀrom HGST are engineered to take
perꢀormance 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 ꢀor read-
intensive applications, and also offers capacities ꢀor today’s
sweet-spot, 800GB and 400GB. With sustained IOPs oꢀ up
to 83,200 read and 30,800 write, and maximum sequential
throughput oꢀ 525MB/s read and 395MB/s write, the s841
SSD enables rapid access to “hot” enterprise data ꢀor
improved productivity and operational eꢁiciency.

Applications/Environments
• Cloud and Datacenters
For complete data protection and reliability, the s841
incorporates extended error correction code (ECC), Secure
Array oꢀ Flash Elements™ (SAFE) technology to protect
against flash die ꢀailure and an exclusive power loss data
management ꢀeature using super capacitors. The s841 is
also backed by a five-year limited warranty or the maximum
petabytes (PB) written (based on capacity).
