ADATA UD320 USB OTG Flash Drive Review: Two For The Road

ADATA UD320 USB OTG Flash Drive

INTRODUCTION:

Transferring any file from a standard USB flash drive to and fro a device that supports USB On-The-Go, whether it is a tablet or a smartphone requires an OTG cable. However, not many people keep this cable in their pocket, so most of the time we end up using a computer to transfer files between them.

This is one scenario wherein ADATA DashDrive Durable UD320 USB OTG flash drive becomes very useful. While most of the flash drive needs a standard USB port, the ADATA UD320 can connect directly to your phone, thanks to its built-in micro USB adaptor.


UNBOXING:

For a device this small, its box really seems an overkill since you can fit more than 10 UD320 in it. The reason behind could be a marketing strategy because almost everything you need to know about the product is already written and illustrated all over the box (no other paper paraphernalia inside).

Contrary to its long name, the device itself is small or shall I say tiny. It composes of three parts, the standard USB flash drive (which contains the storage card), the micro USB adaptor and its cover.


 CONNECTION and PERFORMANCE:

ADATA UD320 In Action

To use it in your Android gadget as a micro USB flash drive, simply remove the end cap and plug it into your smartphone (picture above) or tablet with OTG functions and you are good to go. Based from ADATA, it supports devices with Android 4.1 Jelly Bean or higher.

To connect it to your laptop or computer, just remove the USB flash drive from the adapter. You can also use the micro adaptor for connecting other accessories like wireless mouse or other flash drive (both tested to be working). For better understanding you can refer to the picture below.

Connection Illustration

The UD320 is easily detected by my Cherry Mobile Cosmos Z2, to test its transfer speed ability, I copied a 400MB file from it to the phone and it took 32 seconds to do so while doing the opposite took 40 seconds to complete.

I also connect a micro USB flash drive on my Windows 8 tablet and as expected it works just fine. Doing the same setup as above will take 16 seconds and 24 seconds to complete respectively. When I used the standard USB flash drive alone and connect it on a USB 3.0 port on my laptop, it needs 12 seconds to to complete a 400MB file transfer from the flash drive to the PC, while reversing the transfer is about 17 seconds.


CONCLUSION:

The ADATA DashDrive Durable UD320 USB OTG flash drive is really a great solution to transfer and store files across almost any device. If you are using an Android phone or tablet with non-expandable storage (or already running out of space), the UD320 can give you 32GB of extra storage capacity which you can use on the go.
