USB Flash Drive: Which on to buy

USB Flash Drives, despite the increasingly frequent use of cloud services, have been by our side for years. Thanks to the fragmentation of the speed of the network in our country, it is not always possible to download large files. So, thanks to the increase in memory cuts and the fall in price, using a USB flash drive can be the fastest and most economical solution.

But do we really know its characteristics? Apart from the available GBs and the form factor, it is difficult to focus on the build quality or the transfer speed of the USB flash drive. We try to understand together what can change between multiple types of USB flash drive in order to choose the one that best suits our purposes.


Capacity is certainly one of the major discriminating factors in the choice of USB flash drive. If you intend to use them to move documents and images of little weight, it will be enough to buy a 4 GB model.

They will be so cheap but more than suitable for your purpose. If you are dealing with files of a few dozen MB, such as raw images or PDF a bit more body, opt for USB flash drives from at least 8/16 GB may be the right choice. This will not force you to periodically delete the archived files, perhaps having to review them all to find the most important.

Finally, if video files are your daily bread, or you want to use USB flash drive for playlists of audio tracks, the choice is obligatory. With 32/64 GB, if not 128, you will have all the space, you need. Keep in mind that one minute of 4K video with a modern smartphone takes up about 350 MB of memory. The same speech is valid for high-resolution audio formats. An hour of audio in flac format, will occupy about 600 MB of memory space.


The standard of USB flash drives provides that they meet well-defined criteria. The most recent is USB 3.1, version 3.0 update. The fundamental thing that the standard indicates to us is the theoretical maximum transfer speed. Always remember that these values are expressed in MegaBit. For clarity, 1 GigaBit is equivalent to 125 MB.

  • USB 1.1 : 12 MB/s
  • USB 2.0 : 480 MB/s
  • USB 3.0 : 4.8 GB/s
  • USB 3.1 : 10 GB/s

While technology 1.1 has practically disappeared, version 2.0 still needs to be supplanted. Moreover, even if backward-compatible, the 3.0 standard will be slower if connected to a PC that does not own it.

The transfer speed

As you can guess, the real transfer speed is very different from the theoretical one. It is expressed in MB/s and affects the time it takes to copy the data. If the files you use are mostly of a few MB, you will be relatively interested.

However, if you frequently move movies, images, .iso, or other types of consistent files, the subject changes. We are sure that if you have to go out in a hurry, and you have not copied the files to the USB flash drive, do not take hours to do it.

The speed is indicated both in reading and in writing, usually in this format: 30/15 MB/s. Unfortunately for you, especially the cheaper models do not report these values. If it is an important feature for you, we advise you to spend a little more, but to buy quality USB flash drives.

Other characteristics

In addition to those just listed, there are other important features, but that are not always considered.

    • Dimensions : although it may seem strange, it can be a good criterion of choice. There are really small USB flash drive, which are designed for use on car radios with USB input. If, on the one hand, they can be comfortable, it is really easy to lose them. Furthermore, less material around the memory means less protection in the event of a fall.
    • Encryption : there are more and more USB flash drives with this feature. This way, you can always keep your data safe. They are especially recommended if you use support for work and then do not want others to access your files. Encryption can be applied either through software or already integrated into USB flash drive.
  • Robustness : very useful if you work in ” difficult ” environments. There are USB flash drive certified against water, dust and falls. You can hardly find them in physical stores, while on the net, they are easily available.
