Suneast Portable SSD Nano is the world's lightest USB-C external SSD, weighing just 2.8 grams

The Portable SSD Nano, released by Asahi Electronics under the Suneast brand, is a USB-C external SSD that weighs just 2.8 grams and measures a mere 10.6 x 20 x 13.5mm.

We’ve seen some impressively small SSDs over the years, and some, like the Buffalo 1TB SSD, resemble oversized flash drives more than traditional storage devices. However, even the smallest and lightest among them typically weigh at least 10 grams.

Now, Asahi Electronics has unveiled the Portable SSD Nano, a USB-C external SSD that weighs just 2.8 grams and measures a mere 10.6 x 20 x 13.5mm. For comparison, a U.S. quarter weighs 5.7 grams and measures 24.3 mm in diameter.

The device is so small it could easily be mistaken for a piece of candy, and its toy-like appearance and feather-light build raise valid concerns about how easily it could be misplaced, or worse, accidentally ingested.

The 512GB drive is advertised to have a maximum read speed of 450MB/s and a maximum write speed of 400MB/s.

While those figures don’t place it among the fastest external SSDs in terms of raw performance, they’re more than adequate for everyday tasks like document transfers, photo backups, or carrying around a library of media files.

When inserted into a laptop or mobile device, only 10.6mm remains visible, meaning it sits nearly flush with the host device, a discreet and convenient design.

The drive uses a USB 3.2 Gen 1 Type-C interface and comes preformatted in exFAT, ensuring plug-and-play compatibility across a wide range of devices.

Supported platforms include Windows PCs, macOS, Linux, Android 14 and above, and iPhones and iPads with USB-C running the latest iOS and iPadOS versions.

Despite the novelty, it’s important to remember that this is still a relatively low-capacity drive by today’s standards. With a maximum capacity of 512GB, it won’t replace higher-end SSDs used for content creation or gaming. But for sheer portability, it’s hard to beat.
