Asus has turned the humble thumb drive into something a little more useful: the Adol High Speed Solid State USB Drive (PM310) pairs USB-A and USB-C connectors in one compact body, and tops out at 500MB/s sequential read speeds. That makes the Asus Adol PM310 a neat bridge between old desktops and newer phones, tablets, and laptops – exactly the kind of everyday pain point that still exists because the tech industry cannot settle on one port and move on.
The PM310 is not trying to compete with a full-size external SSD on raw speed, and Asus does not pretend otherwise. Its job is simpler: make transfers easy, avoid adapters, and give users solid-state storage in a format that still fits in a pocket without becoming a dangling accessory nightmare.
Dual connectors in a metal shell
The drive uses a standard USB-A port on one end and USB-C on the other, so it can plug straight into older PCs and newer devices without any extra hardware. Asus has wrapped that setup in a metal chassis measuring 82 x 20 x 7.5mm and weighing 42.9g, plus a built-in flip cap to keep the connectors covered when it is not in use.
That combination is hardly flashy, but it is sensible. Dual-connector drives have become a practical answer to mixed-device households and offices, especially as phones and tablets increasingly double as work machines while plenty of desktops are still stubbornly attached to USB-A.
Asus Adol PM310 speed and platform support
Inside, the PM310 uses a USB 3.2 Gen 2 interface and Asus says it can reach sequential read speeds of up to 500MB/s. That is well below larger external SSDs, but it is still a respectable number for a compact solid-state thumb drive and should be more than enough for documents, photos, and smaller video transfers.
- Interface: USB 3.2 Gen 2
- Top sequential read speed: up to 500MB/s
- Connectors: USB-A and USB-C
- Dimensions: 82 x 20 x 7.5mm
- Weight: 42.9g
The drive also supports plug-and-play use across macOS, Android, HarmonyOS, and iOS or iPadOS. That broad compatibility is the real selling point here: if a storage device works across this many platforms, it becomes less of a niche accessory and more of a small emergency tool you keep in a bag for whenever a transfer job appears.
Asus Adol PM310 pricing for the 128GB to 1TB models
Asus is selling the PM310 in four capacities:
- 128GB model: 280 yuan ($41)
- 256GB model: 409 yuan ($60)
- 512GB model: 629 yuan ($92)
- 1TB model: 959 yuan ($141)
The pricing puts it squarely in the premium thumb-drive camp, where convenience and connector flexibility do a lot of the heavy lifting. That positioning makes sense at a time when portable storage is splitting into two camps: cheap flash drives for casual use, and faster SSD-based drives for people who actually move large files. Asus has clearly chosen the middle path, and the next question is whether buyers will pay extra for the convenience of one drive that can speak both USB dialects.
