The Features To Assess The Best USB Key: Speed, Performance And Added Value

There are several things to consider when analyzing a USB stick. If some have greater storage capacity than others, they may not be as fast and performing as you think.

So I would like to show you the features that I evaluated to choose each USB stick in this ranking with seriousness and rigor …

# Best USB Key Performance

To evaluate the performance of each USB stick I used CrystalDiskMark by performing 100MB, 1000MB and 4000MB tests.

For added security, I did each test three times for each USB stick.

When we talk about Pen Drive, the performance is certainly the most relevant datum. Fortunately, there are now many low-cost USB 3.0 keys available.

There is no reason to buy the previous generation of USB 2.0. The 3.0 models have an incredible data transfer speed.

Think that the best keys in this category are able to transfer files at a speed between 30 and 40 MBps. A good USB 3.0 key can reach 250 Mbps.

Furthermore, the 3.0 standard is also compatible with USB 2.0 ports, but with less speed in writing and reading.

Another thing you should know is that a USB stick from the same brand has different performance based on its storage capacity.

For example, the 32GB SanDisk Extreme has a read speed of 245MBps and a write speed of 100MBps.

The 64GB version has the same read speed, but a much faster write speed of 190MBps. In essence, the greater the cut, the faster the writing speed will be.

# Best Key USB 3.0 Design

Regarding the storage capacity, most of the USB flash drives I have examined are available in different sizes. From 8 GB to 128GB.

How to choose the ones that suit your needs?  Keep in mind that:

  • For transfers of simple files like pages in Word and some 8GB photos are certainly sufficient.
  • A 16GB or 32GB USB stick is ideal for storing or transferring a large amount of MP3 and RAW format images.
  • The main use of the pen will be to archive or transfer movies in HD quality? In this case you will have to save entire folders rich in images and files. Or do you have to use it to make a backup of your PC? In any case you will need a cut of at least 64GB.

In the ranking of the 5 best USB sticks of 2019 I considered only those without the cap (except for the SanDisk Cruzer Ultra Fit, which really deserves).

This is because the uncovered part is potentially exposed to dust and foreign bodies. These could easily compromise the operation of the device. Even an accidental impact would risk distorting the key and preventing regular access to the PC.

I have excluded some sliding keys because often the tape that allows the USB connector to slip, comes out of track. This happens even after a few uses and makes the device unusable. An unnecessary expense.

# Features Best USB Key

With normal use of the USB stick, the internal memory may deteriorate.  It happens when the data is always rewritten in the same memory cell.

Think of a waterfall that breaks on a precise point of a rock. In a relatively short time you will see the first signs of wear.

Some USB sticks have a technology called wear leveling. This helps reduce the premature deterioration of the NAND Flash memory by optimizing their exploitation over time.

As if the first waterfall broke on the entire rock, not on a specific point.

The final result? The units with wear leveling often enjoy a much longer life than the counterparts without.

But I guess you’re not just looking for a long-lasting USB stick. You also want to be sure that the data on that drive is best protected.

  • Some devices allow you to protect their content with a password.
  • Others have hardware encryption to make the data inviolable.
  • Some USB sticks also have cloud backup features. So you don’t have to worry about file loss anymore.
