Purchase Criteria

Next, we’re going to study a number of important criteria that you should consider before purchasing a USB memory stick. This way, it is more likely you will be satisfied with your purchase. We wouldn’t want you to be disappointed after a few months with your new USB stick.

  • Intended use
  • Storage capacity
  • Speed
  • File format
  • Resistance
  • USB physical construction
  • Size
  • Sensitivity of the data being saved
  • Brand

Intended use

When choosing a USB memory stick, it is very important that you are clear about how you are going to use it. You may need a pen-drive for occasional use, such as installing an operating system. Or for frequent use, such as storing documents you’re going to use on different computers. Or to save and play back high quality videos.

Storage capacity

Obviously, capacity is going to be a fundamental criterion to consider when choosing the flash drive you are going to buy. We live in a world that requires us to keep and store more and more information. Fortunately, today’s flash drives also offer increasingly higher storing capacities.

The era of 128 MB pen-drives is long gone. Today, the capacity of USB Flash Drives is measured in GB. It is even possible to find a 64 GB USB stick for less than 20 bucks. However, don’t think it makes sense to buy a flash drive with a much larger storage capacity than you need.

Data transfer speed can be an important issue if you need to copy a lot of heavy information. In this respect, it is important to distinguish between USB 2.0, USB 3.0 and, most recently, USB 3.1 standards. You can consult the following table to find out the transfer speed of each of them.

USB 2.0 USB 3.0 USB 3.1
Transfer rate (theoretical) 480 Mb/s 5 Gbps 10 Gbps

It is necessary to clarify that these are theoretical values and that in reality these can vary. Not all USB Flash Drives are going to reach those transfer rates. In addition, manufacturers sometimes provide peak data rather than average speeds. It is also important to distinguish between reading and writing speeds.

File format

The format, or file system, is the way a memory unit organizes the content or information it stores. In general, to be able to use a flash drive or any other storage device it is first necessary to format it. Most often on pen-drives the file system is already an industry standard.

However, if this is not the case, you must choose the correct one for the device with which you are going to use it. To do so, there are different utilities and applications that will allow you to format it very easily and quickly. It may also happen that the factory format is not suitable for the equipment with which you are going to use it.


Nothing is more frustrating than losing the accumulated information stored in these devices because, out of nowhere, the flash drive suddenly stops working. It is true that there are programs that can help you retrieve this lost information. However, they are not always effective. So, as the saying goes, prevention is better than having to find a cure.

Because USB Flash Drives are designed for transport, it’s important that they are rugged. A fairly common problem with pen-drives is their low resistance to voltage changes. In addition, USB Flash Drives are often subjected to shock and vibration.

For this reason, you should choose a product made of good quality materials.

USB physical construction

Today, there are many different types of USB memory stick constructions. There are retractable, with or without lid, plastic, metal and keychain, among others. In this sense, it is good that you choose one that offers a solid body. If it’s plastic, it’s good that the plastic is hard and that it’s gummed.


With flash drives, size does matter. Don’t forget that one of their main attractive features is that they take up little space. These are devices designed for easy transport. In fact, very large and thick pen-drives can cause space problems when connected to a computer, especially laptops.

In general, it may seem that a smaller USB memory stick is better than a larger one. However, this will not always be the case as this will depend more on the quality of it’s components. Nonetheless, it will be easier to transport as it will occupy less space. And, of course, depending on its intended use, this can be an important factor.

Sensitivity of the data being saved

The data you’re going to save on the USB stick may be very sensitive. In that case, it might be best to buy one with a Hardware security encryption system. This way, if you lose it, no one will be able to access the information stored in its memory. This way if it is lost, the only consequence will be having to replace the item.


Choosing the right brand is important. The brand of a product is closely related to aspects such as quality, warranty, durability and price. Some of the most recognized manufacturers’ brands are: SanDisk, Lexar, Trascend, Toshiba, Corsair, Verbatim and Kingston.


While we live in a hyper-connected world, USB Flash Drives are here to stay and will be with us for a long time to come. Not in vain, since they offer a series of advantages that no other storage medium can match. They are small, very manageable, versatile and keep getting more and more storage capacity.

In order to buy the best one for you, don’t miss reviewing all the frequently asked questions we discussed in this guide. Remember that of course, price is a key factor, as are storage capacity and transfer speeds. However, resistance and branding should not be overlooked, since these two factors will influence the durability of the memory.

We hope you found this guide helpful and helpful. If you think it has, we would be very grateful if you would share it with your friends.
