Neutron Shield™

Light rays coming from space

Protection against the (invisible) elements

Single event upsets, or SEUs for short, can cause severe data integrity issues by interfering with in-transit data as well as data stored in an SSD’s DRAM and NAND flash. 

SEUs can have a variety of causes, but mainly occur as a result of cosmic rays – elementary particles and atomic nuclei that penetrate anything that crosses their paths as they travel through space. Naturally occurring background radiation and radiation from other sources such as medical and engineering equipment are also potential causes of SEUs.

We developed our exclusive Neutron Shield™ technology to tackle this normally inescapable threat to data integrity, providing unmatched protection against SEU-induced data integrity issues. 

In mission-critical applications, Neutron Shield™ is an ideal complement to other Exascend data integrity-securing technologies such as RAID ECC and Data Path Protection – providing an additional layer of protection against data integrity issues.

Recommended applications

Mission critical

Reliability comes second to none in mission critical applications – where failure is not an option.


Next-generation telecom requires ultra-fast storage devices that excel in any environment.


Excel under enterprise-level workloads day after day.
