Supermicro 2x SATA M.2 RAID AOC-SLG2-2TM2-O

Data centers and high-performance workstations often need fast, flexible storage without sacrificing PCIe slots. The Supermicro AOC-SLG2-2TM2-O addresses this by adding two M.2 SSD slots through a single PCIe 3.0 x8 interface. Whether you're building a compact server for virtualization or upgrading a workstation for heavy workloads, this adapter lets you install two M.2 NVMe or SATA drives in RAID 0, RAID 1, or JBOD mode. It supports common M.2 lengths (2242, 2260, 2280, 22110) and includes both low-profile and full-height brackets, so it fits in almost any chassis. Boot from the M.2 array to slash boot times, or use it as a high-speed cache for frequently accessed data. With broad OS compatibility and a rugged design, it's a practical way to modernize storage without replacing your entire system.

Key specifications

• Expansion card standard: PCIe 3.0

Why choose it

This adapter maximizes storage density without using multiple PCIe slots. By supporting both NVMe and SATA M.2 drives, it gives you flexibility to balance speed and cost. The hardware RAID engine offloads RAID calculations from the CPU, ensuring consistent performance. The included low-profile bracket makes it suitable for slim servers and compact workstations, while the full-height bracket covers standard desktops. Supermicro's reputation for reliable server components means you can trust it in 24/7 environments.

Ideal use cases

• Boot drive for servers and workstations to reduce boot times and free up drive bays.
• High-speed cache or tiered storage in virtualization environments (VMware, Hyper-V).
• Compact RAID 1 mirroring for critical data in small form factor systems.
• Upgrading legacy servers with modern NVMe storage without replacing the motherboard.
• Content creation workstations needing fast scratch disks for video editing or 3D rendering.

Good to know

The card requires a PCIe 3.0 x8 slot (or larger) and does not require additional drivers for most operating systems, as it uses standard NVMe and AHCI protocols. For RAID functionality, ensure your motherboard supports PCIe bifurcation or use the onboard RAID controller. The card is RoHS compliant and backed by Supermicro's warranty. Always verify M.2 drive compatibility (key M) and thermal clearance, especially for 22110 drives in tight cases.
