It's a USB-C drive with dual heads, so you can plug it in with USC-C or USB-A. It's handy to have on hand if you're working with multiple devices, like old laptops or printers which still use USB-A. Nowadays it's less important for most folks and a lot of them would be content with just the USB-C side to reduce size, and you can always fall back to a USB-C to USB-A adapter or a USB hub on those rare occasions. But if you require both frequently, it's nice to carry this little guy and avoid extra dongles or adapters.

This 256GB Ultra Dual Drive has quickly become one of my favourite tech accessories. Its dual-interface design—with both USB Type-C and USB Type-A—makes it incredibly convenient for transferring files between my MacBook, PC, Android phone, and other devices, eliminating the need for any adapters.

The read/write speeds are fast and reliable, making large file transfers (videos, presentations, backup folders) smooth and frustration-free. The build quality feels solid, and it’s compact enough to carry on a keychain or toss in a bag without concern. It’s an excellent tool for anyone needing flexible, high-capacity portable storage. Whether for work, backup, or multimedia use, it performs exactly as promised. Highly recommended for productivity and peace of mind.

This is good.
I'm ok with this. It works in my phone.
Did a speed test with both ends. (It's consistent)
Look at the pic and make your decision.

Good enough

Good price for a good quality, large capacity, yet very tiny sized USB memory stick. Good to have both USB A and C connectors.
