Responding to the rapidly growing demand for high-density, low-latency storage in AI servers and data centers, SSSTC has introduced its next-generation enterprise solid-state drive (SSD), the ER4 Series SATA SSD. The new series offers capacities of up to 16 TB, making it one of the few SATA SSDs on the market to deliver such high density. It also features impressive random read/write performance of 98K / 30K IOPS, while the 8 TB model achieves 98K / 55K IOPS—combining large capacity with exceptional performance ideal for AI inference, real-time analytics, and high-concurrency workloads.

The ER4 Series uses a 2.5-inch SATA 6 Gb/s standard interface and supports hot-swapping, enabling direct replacement of traditional hard disk drives (HDDs). This allows businesses to upgrade their storage seamlessly while maintaining existing infrastructure and optimizing cost efficiency. The lineup includes 16 TB (15.36 TB) and 8 TB (7.68 TB) models, both delivering sequential read/write speeds of up to 550 MB/s and 530 MB/s, respectively. Each model also provides 98K random read IOPS, significantly enhancing processing capabilities in high-concurrency environments—particularly beneficial for OLTP workloads, AI inference, cloud platforms, and data analytics requiring low latency.
