s841 SAS

Performance and Capacity for

the Data Center

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).

• Enterprise-class servers and High Performance

Computing

• Space and/or power constrained environments

• Web servers

• Video on demand, Streaming media

• Database acceleration/Archival storage
