PCIe adapter card SILVERSTONE SST-ES02-PCIe with dual M.2 NVMe slots

The SILVERSTONE SST-ES02-PCIe is a PCIe adapter card that adds two M.2 NVMe slots to a compatible system, allowing installation of high-speed NVMe SSDs in a single expansion slot. Intended for desktop PCs, workstations and servers with an available PCIe slot, the adapter enables increased storage capacity and supports configurations that may include RAID when combined with a suitable host controller. The card is designed to be installed directly into the motherboard PCIe slot and presents both M.2 drives to the host system for use as independent volumes or as part of multi-drive configurations.

Advantages

The adapter provides a compact solution for integrating two M.2 NVMe SSDs without requiring additional drive bays, maximizing storage density in systems with limited internal space. Its PCIe interface offers direct communication with the host for low-latency, high-throughput storage performance subject to the capabilities of the system's PCIe lanes and chipset. The dual-slot layout allows flexible storage expansion and the possibility of combining drives for higher capacity or improved performance when supported by the host.

Suitable for

• Desktops and workstations requiring additional NVMe storage
• Servers needing compact dual M.2 NVMe expansion
• Systems where installation of 2.5" or 3.5" drive bays is not feasible
• Environments that may use multiple NVMe drives in RAID or independent volumes (controller dependent)

Key specifications

• Interface: PCI Express x4 (installed in PCIe expansion slot; actual lane usage depends on motherboard)
• M.2 slots: two M.2 NVMe (Socket 3, M key) for PCIe NVMe SSDs
• Form factor: low-profile adapter card suitable for standard PCIe slots
• Compatibility: designed for systems that support NVMe devices through PCIe; host controller/BIOS support required for RAID or boot use
• Cooling: passive open-frame design for airflow from chassis fans (no active fan included)

How to use

Power off the system and unplug it from mains before installation. Insert the SILVERSTONE SST-ES02-PCIe into an appropriate PCIe expansion slot on the motherboard, secure the card to the chassis, and install M.2 NVMe SSDs into the two M.2 slots following the correct orientation for M key sockets. Tighten the mounting screws to secure each M.2 drive. After installation, reconnect power and boot the system. Enter the system BIOS or operating system storage management tools to verify that both NVMe drives are detected. Configure drive settings or RAID through the system BIOS or software utilities if the host platform provides controller support for multi-drive configurations.

Usage recommendations

Ensure the host motherboard and BIOS support NVMe devices and the required PCIe lanes for optimal performance; consult the motherboard manual for lane allocation. Use adequate chassis airflow or additional cooling if installing high-performance NVMe SSDs, and follow anti-static precautions during installation. For RAID configurations or booting from drives on this adapter, confirm host controller compatibility and, if necessary, update BIOS or drivers before configuring storage arrays.
