📋 Specifications & features of Acer UM310
From Acer’s official product pages and datasheets, here are key specs:
| Parameter | Detail |
|---|---|
| Interface | USB 3.2 Gen 1 (i.e. “SuperSpeed” / USB 3.0 equivalent) |
| Read Speed | Up to 115 MB/s |
| Write Speed | Up to 90 MB/s |
| Dimensions | 41.54 mm × 14.3 mm × 6.75 mm |
| Weight | 8.0 g |
| Capacities | 32 GB, 64 GB, 128 GB, 256 GB (and in some markets, more) |
| Durable body | The name “Metal” suggests a metal (aluminum alloy) casing for durability, shock / dust resilience (common in such designs) (implied in marketing) |
| Compatibility | Backwards compatible with USB 2.0 / USB 3.0 devices (since USB 3.2 Gen 1 is retro-compatible) |
Some product listings mention slightly different speeds (e.g. read ~120 MB/s, write 100 MB/s) depending on capacity or test conditions.
⚠️ Notes & caveats
-
The quoted speeds (115/90 MB/s) are maximum theoretical speeds in optimal conditions (fast USB port, good controller, ideal conditions). Real-world speeds may be lower due to file sizes, fragmentation, host device performance, etc.
-
Some sellers list lower write speeds (for example, one merchant claims write 40 MB/s for 128 GB model)— always check the exact spec for the specific capacity you pick.
-
The casing being metal helps in durability, but still avoid bending, physical shock, or exposure to extreme temperatures.
-
Ensure your PC / laptop USB port supports USB 3.x to get higher speeds — using a USB 2.0 port will limit performance.
