File transferring speeds

Nobody wants to wait for eternity to transfer a large file, which is why file transferring speed is another important USB flash drive characteristic. These speeds are usually designed in MB/sec and they show how fast the unit can write and retrieve data from its storage. Most USB flash manufacturers are listing two separate speed figures, one for retrieving and other for writing data.


Three separate generations of USB flash drives have been released, since the introduction of the first production models in the early 2000.

  1. First generation models- had a storage capacity of only a few MB and they were the first commercial USB flash drives.
  2. USB 2.0 models- had much bigger storage than first generation models, and some of them could store up to several GBs of files. Their transferring speeds were 20% higher than the ones in the first USB flash drive models.
  3. USB 3.0 models– come with an increased storage capacity. They are 10 times faster than USB 2.0 models and they can store several dozen GBs.


USB flash drives often feature unique designs. Purpose of some of these designs is to make USB flash drives more useful, while others make them shock-resistant or improve their promotional value.

Other features:

In order to make USB flash drives more practical, manufacturers often introduce various extra features. These include:

  • Aluminum casing- which improves flash drive’s durability and makes it shock-resistant;
  • Retractable USB plug- which keeps the port safe and clear from dust and debris;
  • Micro USB plugs- which makes an USB flash drive cross-compatible with desktops and mobile devices;

Like most other gadgets USB flash drives usually come with 2 or 5 years warranty. Warranty doesn’t protect you from failures caused by human factors, but the fact that you can make a warranty claim for regular product failure definitely makes the use of these drives more relaxed and enjoyable. The best drives with 64 and 128 GB capacity usually cost from $20 to $40 and they can be bought online, as well as in regular location-based tech stores.
