This article covers GRAUGEAR M.2 PCIe 4.0 アダプターカード NVMe SSD M-Key用 大型アルミニウムヒートシンク 2280.

Overview

The GRAUGEAR G-M2PCI01 is a PCIe 4.0 x4 adapter card that converts an M.2 NVMe SSD (M-Key) into a standard PCIe expansion card. It supports data transfer rates up to 64 Gbps and features a large aluminum heatsink with silicone thermal pads to maintain stable performance under sustained loads. The card accommodates M.2 lengths of 2280, 2260, 2242, and 2230, and includes both high-profile and low-profile slot brackets for flexible installation in desktop PCs. It is backward compatible with PCIe 3.0 and 2.0 slots, making it a versatile upgrade path for older systems.

Connectivity & Compatibility

This adapter connects via a PCIe 4.0 x4 interface and is designed exclusively for M.2 NVMe SSDs with an M-Key notch. SATA M.2 SSDs (B-Key or B&M Key) are not supported. The included brackets allow installation in standard high-profile or low-profile PCIe slots, fitting most desktop PC cases. When used in a PCIe 3.0 or 2.0 slot, the maximum bandwidth drops to approximately 32 Gbps or 16 Gbps respectively, but the SSD remains fully functional.

Product Info

The GRAUGEAR G-M2PCI01 is available on for around ¥5,335 (tax included). Warranty details are provided by the manufacturer; please check the product page for specifics. The package includes the adapter card, large aluminum heatsink, four silicone thermal pads, high-profile bracket, low-profile bracket, and mounting screws. It occupies an entry-to-mid-range market position, offering excellent value for users who want to add a fast NVMe SSD without upgrading their motherboard.

Best Use Cases

  • Desktop users with limited M.2 slots: If your motherboard has only one M.2 slot, this adapter lets you add another NVMe SSD via a PCIe slot. Ideal for those who want to maximize PCIe 4.0 SSD performance. - Users with older motherboards lacking M.2: The backward compatibility with PCIe 3.0/2.0 allows you to use a modern NVMe SSD on legacy systems, though at reduced speeds. - DIY builders seeking a simple upgrade: Installation is straightforward—mount the SSD, attach the heatsink, and insert the card into a PCIe slot. No special tools or drivers required. - Not recommended for: Users who need SATA M.2 support, laptop upgrades, or systems with only PCIe x1 slots (severe bandwidth limitation).
