SK Hynix Gold S31 250GB 2.5-inch SATA SSD

The SK Hynix Gold S31 250GB (SHGS31-250GU-2) is a 2.5-inch SATA III solid-state drive built on SK Hynix's own 128-layer 3D TLC NAND flash, paired with an in-house controller to deliver consistent sequential read performance of up to 560 MB/s and sequential write performance of up to 525 MB/s. The drive operates on the industry-standard SATA 6 Gb/s interface, ensuring broad compatibility across existing enterprise server platforms, storage enclosures, and workstation deployments without requiring additional host controller investment.

Designed for sustained reliability, the Gold S31 carries a 0.7 DWPD (Drive Writes Per Day) endurance rating and a total bytes written (TBW) rating of 120 TBW for the 250GB capacity point, backed by a mean time between failures (MTBF) rating of 1,500,000 hours. Its low-profile 2.5-inch, 7mm z-height form factor accommodates slim chassis designs and high-density storage trays alike, making it suitable for blade servers, rack-mount systems, and edge appliances where space efficiency is a priority.

The Gold S31 targets read-intensive and mixed-use enterprise workloads where SATA connectivity is the incumbent standard and cost-efficient, high-capacity flash storage is required. Ideal deployment scenarios include boot and OS volumes, virtual desktop infrastructure (VDI) persistent storage, log and audit repositories, and edge computing nodes requiring dependable flash performance in thermally constrained environments. Its native SK Hynix vertical integration — from NAND fabrication through controller design — supports supply chain predictability for enterprise procurement teams sourcing across UAE, GCC, EMEA, and APAC regions through Omnixon Global.

Ideal for

• Server boot and operating system volume replacement for legacy HDD arrays in rack-mount and blade server environments
• Virtual Desktop Infrastructure (VDI) persistent disk storage requiring consistent low-latency read performance across concurrent user sessions
• Edge computing nodes and IoT gateway appliances demanding reliable flash storage within strict power and thermal budgets
• Log aggregation, audit trail, and compliance data repositories benefiting from sustained sequential write throughput on SATA platforms
• Secondary read cache or tiering layer in hybrid storage architectures alongside larger capacity HDDs
• Workstation and content creation system primary storage refresh for media processing, rendering, and CAD workflows
