Biwin has announced a teeny-tiny new type of SSD with shock and water resistance built-in, but it might be a while before you see one in your next mobile device

MicroSD cards feel a bit behind the times, don’t they? While I’ll always be impressed by just how much storage can be squeezed into such a tiny footprint, they’re rather slow, ponderous affairs to use in practice, particularly in regards to gaming devices. Enter Biwin, a giant in the space of memory and storage that has just announced a new type of teeny-tiny SSD that looks like it might show some promise.

Biwin refers to its new creation as a “Mini SSD”, which seems appropriate, as it’s significantly smaller than a good ol’ British pound coin (via The Verge). At just 15 x 17 x 1.4 mm, it’s the sort of thing you might accidentally inhale, which is remarkable given the storage and speed potential inside.

Biwin says the drive will be available in 512 GB to 2 TB capacities, and is capable of up to 3,700 MB/s read speeds and 3,400 MB/s writes. That might not sound particularly fast compared to a modern Gen 4 or Gen 5 SSD, but even the fastest V90-rated MicroSD cards top out around the 300 MB/s read mark, so the Mini SSD looks set to give them a complete pasting in the benchmarks.

Plus, Biwin says that its Mini SSDs are IP68-rated, which according to the classification means they’re “dust tight”, and capable of being immersed in one meter of water without incident. Throw in some internal shock-proofing that BiWin says means they can survive drops of up to three meters, and you’ve got a pretty tough customer.

The real sticking point here, however, is that being a new type of SSD of this size, devices will need a proprietary socket to use one. That means device manufacturers getting on board with support, which is no easy task given the status quo of MicroSD cards as things stand—although there do appear to be some green shoots in this regard.

The Strix Halo-powered, battery-backpacked GPD Win 5 is said to have a Mini SSD slot, as does the yet-to-be-released OneXPlayer SuperX laptop/tablet hybrid. That’s a pretty small selection for now, and the adoption of this tech among consumers will likely rely on a plethora of devices supporting the new drive format.

These things take time, but it’ll be interesting to see if more major manufacturers jump on the Mini SSD train. I’m prepared to bet it’ll be a while before we see them in our mobile devices, if they take off at all. The tech industry is a fickle thing, and introducing a new type of drive into a crowded mobile device market is by no means an easy undertaking.

Still, Biwin is a huge manufacturer, so perhaps it has a better chance than most—and a start must be made somewhere. Speedy storage can be found in many forms these days, but for now it looks like Mini SSD tech might stand alone in its combination of ultra small size and decently fast speeds. I’d say I’d like to get my hands on one in my next handheld gaming PC, but knowing my luck, I’d probably sneeze it into the great beyond the second I pulled it from the box.
