Manufacturer description

The mosDART 128GB Dual USB C 3.2 Flash Drive solves the cable-and-adapter problem that shows up the moment you try moving footage off an iPhone 15, 16, or 17 and onto a MacBook. One end is USB-C, the other is a rotating USB-A connector, so the same 128GB stick plugs into a laptop, an Android phone, an iPad, or a desktop without a dongle in between. Transfer speeds reach up to 150MB/s, so a batch of 4K clips or a photo library moves in a session rather than an afternoon. The USB-C connector is extended past the housing, which means you can plug it in through most phone cases instead of…

SpecPicks Verdict

SpecPicks scored MOSDART 128GB Dual USB C 3.2 Flash Drive using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. mosDART's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for accessories of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Does this work with an iPhone 15, 16, or 17?

Yes. mosDART lists compatibility with iPhone 15, 16, and 17, which use USB-C ports. The USB-C connector is extended so it reaches past most phone cases.

How fast is the transfer speed?

Up to 150MB/s per mosDART. Actual speed depends on the port you plug into, file size, and whether you are reading or writing - large single files come closer to the ceiling than many small ones.

Can I use it with both my MacBook and an older laptop with USB-A ports?

Yes. It has a USB-C end and a rotating USB-A end on the same drive, so it plugs into a MacBook's USB-C port or a standard USB-A port with no adapter.

What format does it come in, and will it work on Mac and Windows?

It ships formatted exFAT, which reads and writes on both macOS and Windows, plus Android and iPadOS. You can reformat it if you need a platform-specific filesystem.

What does the LED light do?

It blinks while data is transferring and stops when the transfer is finished, so you have a visual cue before ejecting the drive.
