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 �� Video Editors & Content Creators Edit 4K/8K projects directly from the enclosure. At 3,800 MB/s, large video files load instantly. Perfect for on-set workflows with a MacBook Pro. �� Mac Mini M4 Expansion The Mac Mini M4 has limited internal storage. Add fast, affordable NVMe storage via USB4 — it’s practically as fast as internal. �� Fast Backups & Migration Transfer 1TB in under 5 minutes. Clone drives, migrate systems, or create Time Machine backups at full NVMe speed. �� Portable Gaming Storage Store your Steam/game library on an external NVMe and take it between machines. Load times rival internal SSDs. Technical Specifications Model AA24M11 Controller Chipset ASMedia ASM2464PD Host Interface USB4 (USB-C connector) Host Compatibility USB4 / Thunderbolt 5 / 4 / 3 · Backwards: USB 3.2 / 3.1 / 3.0 PCIe Interface PCIe Gen4 x4 Max Transfer Speed 40 Gbps (read up to 3,819 MB/s) M.2 Slot M Key & B M Key — NVMe PCIe only (not SATA) Supported M.2 Sizes 2230 / 2242 / 2260 / 2280 Max Capacity 8TB Cooling Fanless — full aluminium passive heatsink Protocols NVMe 1.4c · BOT & UAS · USB PD 3.1 · S.M.A.R.T. · UASP · TRIM Dimensions 115.5 × 58.5 × 15mm OS Compatibility macOS (plug-and-play) · Windows · Linux · Android Power Bus powered (via USB-C) ⚠️ 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.
