To be honest, if you have the means and don't need something that is this small, then go for the SanDisk Extreme Portable SSD. Writes and reads on this device are slow (though not as slow as other flash drives). The option to have USB Type-C and Type-A in one drive is nice, but it depends on the device you are plugging into. For example, Apple's MacBook Pros barely accommodate this flash drive because of the spacing between the Type-C ports on the Mac. That's where you may be better off with the SanDisk Extreme Portable SSD which uses a Type-C cable that isn't as wide as this flash drive AND it comes with the Type-C to Type-A adapter. The other issue I have with this is that the slide lock is like all others: they will break or wear out. Mine hasn't broken yet, but it will after enough use.
