Asus Unveils Dual-Port Portable SSD with 500MB - s Speeds

Imagine moving a 4K clip from your phone to an older PC without fumbling for adapters. That is the small promise Asus is selling in China with its new Adol High Speed Solid State USB Drive, model PM310. It looks like a chunky thumb drive, but inside sits solid-state storage tuned for quick handoffs between devices of different generations.

Two ports, fewer cables

The PM310 is built around a simple, practical idea: USB-A on one end, USB-C on the other. Plug into a legacy desktop, then flip it and plug into a modern laptop, tablet, or smartphone. No dongles. No fuss. The metal chassis measures 82 x 20 x 7.5 mm and tips the scales at 42.9 g. A flip cap keeps the connectors safe when the drive is tucked away.

Under the hood, Asus uses a USB 3.2 Gen 2 interface. Sequential read speeds top out at around 500 MB/s. That’s not on par with full-size external NVMe drives, but for a pocket-sized solid-state stick, it hits a useful sweet spot: fast enough to move large files quickly, small enough to live on a keyring.

Quick takeaway: compact, cross-device SSD with up to 1 TB and 500 MB/s reads.

Compatibility is broad. The drive supports plug-and-play on macOS, Android, HarmonyOS, and iOS or iPadOS, so photographers, content creators, or anyone who juggles multiple ecosystems can transfer data without switching cables or cloud upload routines.

Asus is shipping the Adol PM310 in four capacities, with euro pricing as follows:

• 128 GB — about €36
• 256 GB — about €53
• 512 GB — about €82
• 1 TB — about €125

Who should consider this drive? If your daily workflow includes bouncing files between a phone and a PC, or you need a tiny, reliable transport for large projects without relying on the cloud, the PM310 is worth a look. If raw speed is your obsession, larger portable NVMe drives pushing 1,000 MB/s or more will remain the go-to choice.

For context, manufacturers like Colorful have recently introduced compact SSDs that hit roughly 1,000 MB/s and add features such as Apple ProRes recording support for video workflows. The Adol PM310 trades peak throughput for convenience and compatibility.

It’s a pragmatic product: small, sensible, and designed to remove a tiny but persistent annoyance—adapter juggling—so you can get on with the work.
