ADATA’s Type-C OTG Flash Drive is very cleverly designed

The design of ADATA’s Type-C OTG Flash Drive dual standard connector is extremely clever. It’s both a regular USB connector and a reversible USB Type-C plug. You pull the drive out of its shell and reinsert it to change the type of plug that’s accessible. 

Eventually, all Macs will come with USB Type-C (or USB-C, for short) ports, but for now the 12-inch MacBook is the only one that does. And it only has one such port, which limits its expandability and connectivity. ADATA’s Type-C OTG Flash Drive helps with this situation by making it simple to move files between Macs (or PCs) with USB 2.0/3.0 ports and the MacBook.

Another advantage of the ADATA drive: with Type-C, USB is easier to use than before. Most of us have experienced flipping traditional USB connectors around to figure out which side is up and which is down. With USB-C, the connector is reversible, so that's no longer a problem.

Alas, the housing of the ADATA is all plastic, so it's not as sturdy as the extruded aluminum models available. However, I shouldn’t complain about the materials,  as the ADATA drive is surprisingly affordable. It comes in 16GB, 32GB, and 64GB for, respectively, about $12, $18, and $25 at With an added 64GB you can store an extra 29,500 photos (at least, if each is around 2MB), so the drives are well worth the moolah.

The capless design of the ADATA drive is convenient, as there’s no cap to lose. However, the flash drive is VERY small, so it easy to lose. The plastic bar provided for a keyring is slim and delicate, so you’ll have to be careful or your ADATA drive could be lost.
