Description
USB4 NVMe Enclosure — 40Gbps. Fanless. Compact.
ASMedia ASM2464PD · PCIe Gen4 x4 · Thunderbolt 3/4/5 & USB4 · Mac Plug-and-Play
Why 40Gbps Changes Everything
Most external NVMe enclosures are limited to 10Gbps (USB 3.2 Gen 2) — that’s a ceiling of about 1,000 MB/s, regardless of how fast your SSD is. A budget 10Gbps enclosure will bottleneck even a mid-range NVMe drive.
The AA24M11 connects at 40Gbps via USB4, unlocking real-world speeds of 3,800+ MB/s read and 3,100+ MB/s write. That’s nearly 4× faster than a 10Gbps enclosure — and faster than most internal SATA SSDs.
| Interface | Max Bandwidth | Real-World Speed |
| USB 3.2 Gen 2 (10Gbps) | 10 Gbps | ~1,000 MB/s |
| USB 3.2 Gen 2×2 (20Gbps) | 20 Gbps | ~1,800 MB/s |
| USB4 / TB3/4 (40Gbps) ✅ This enclosure | 40 Gbps | ~3,800 MB/s |
Key Features
| ⚡ 40Gbps USB4 ASMedia ASM2464PD controller — the same chip used in premium enclosures from UGREEN and Sabrent. Read speeds up to 3,819 MB/s with a PCIe Gen4 SSD. |
🔇 Fanless Aluminium Full metal housing acts as a passive heatsink. Zero noise, zero moving parts. Independent testing showed it outperformed fan-cooled competitors thanks to its thermal design. |
| 🍎 Mac Plug-and-Play Works instantly on macOS — no drivers needed. Also supports Windows, Linux, and Android with plug-and-play or simple driver install. |
🔌 Universal Thunderbolt Compatible with USB4, Thunderbolt 5, Thunderbolt 4, and Thunderbolt 3. Backward compatible with USB 3.2/3.1/3.0 at reduced speeds. |
| 📏 All M.2 Sizes Fits 2230, 2242, 2260, and 2280 M.2 NVMe SSDs. M Key and B+M Key supported. Up to 8TB capacity. |
🛡️ Data Protection S.M.A.R.T. drive monitoring, NVMe error reporting & recovery, UASP acceleration, hot-plug support, and NVMe power management. |
Perfect For

⚠️ Important Compatibility Notes
NVMe only — does NOT support M.2 SATA SSDs. Your SSD must be PCIe NVMe (M Key or B+M Key).
40Gbps requires USB4 or Thunderbolt 3/4/5. The enclosure is backward compatible with USB 3.2/3.1/3.0, but speeds will be limited to the port’s maximum (e.g., 10Gbps on USB 3.2 Gen 2).
SSDs with heatsinks won’t fit — remove any aftermarket or factory heatsink before installation.
