Exascend Expands SA4, SI4, and SE4 SATA Industrial/Enterprise 2.5-Inch SSD Line to 15.36TB Capacity

Exascend, Inc. announces the expansion of its 2.5-inch SATA SSD series – SA4, SI4, and SE4 – to a 15.36TB capacity.

This advancement redefines the limits of SATA SSD storage, catering demanding applications like digital/network video recorders and media post-production.

The firm’s 15.36TB SSDs are engineered for efficiency across diverse environments. The SE4 series operates in standard temperatures from 0°C to 70°C, while the SA4 and SI4 series feature robust coatings for extreme temperatures ranging from -40°C to +85°C, ensuring reliability in both enterprise settings and harsh conditions.

Built with 3D TLC NAND flash technology, the company’s SATA SSDs employ direct write-to-TLC to maintain stable RW performance, effectively mitigating performance drop-off when the SLC cache is exhausted. These SSDs boast high-density integration, with 16 NAND flash ICs, each with 1TB capacity, on a single PCB within a slim 7mm housing. This design innovation not only maximizes storage density but also integrates hardware-based power loss protection (PLP), securing data even during unexpected power failures.

Exascend’s proprietary SuperCruise technology enhances write performance, while optional TCG Opal 2.01 encryption offers added data security. These features make the SA4, SI4, and SE4 series upgrades from traditional HDDs, delivering performance and reliability.

For applications requiring higher endurance, the SATA SSDs are also available in pseudo SLC (pSLC) mode, supporting capacities up to 3.84TB with an endurance rating of 5 DWPD.

The expanded SA4, SI4, and SE4 series are available for order.
