Overview
Virtium's StorFly E1.S platform is an industrial-grade NVMe SSD family that spans three classes — StorFly, StorFly DC and Epistor — so designers can balance performance, endurance and capacity for a given embedded or industrial-edge system. Capacities run from 256GB to 16TB.
The E1.S form factor was created to overcome the capacity, cooling and hot-plug limits of M.2, and it has since spread from rack servers into industrial applications. Virtium pairs that form factor with PCIe Gen5 NVMe performance and -40°C to +85°C industrial-temperature operation.
For long-lifecycle programs the platform offers advanced industrial-grade NAND with an operating life exceeding seven years, up to 5 DWPD endurance in pSLC mode, power-loss protection, and OCP S.A.F.E / TCG Opal security. A controlled BOM and firmware policy avoids disruptive requalification.
Key Benefits
Enterprise storage density with industrial ruggedness and a 7+ year horizon. PCIe Gen5 throughput to 16TB, -40°C to +85°C operation, pSLC endurance up to 5 DWPD, PLP and TCG Opal security keep data safe where requalification is expensive.
Applications
Industrial edge computing storage; data-center-adjacent and rack deployments; embedded systems in harsh environments; telecom and networking equipment; medical and transportation platforms; long-lifecycle OEM designs.
