How to Choose a USB Flash Drive

USB Flash drives have become very useful to the modern generation of men. It is convenient and easy to use. All that is required is to connect to a USB port and you can easily copy, move or delete files/folders.

Data are transferable from one computer to the other with the use of a USB Flash drive.

A USB flash drive is a data storage device that includes flash memory with an integrated integrated Universal Serial Bus (USB) interface. It is removable, rewritable and much smaller than an optical disc.

Flash drives are a convenient way to bring your files with you and open them on a different computer.

Some of SPAR customers have been asking questions on: what to look for when choosing/buying USB Flash Drives?

Now to answer this question and help our valued audience, we have put this piece together and trust you find it useful as a guide to helping you make better choice.

  1. The amount of memory available for use

  2. Reading/writing speed

  3. Physical size

  4. Brand

  5. Other features

With the points highlighted above, let us run through them one by one. Get a drink as you go through this seamlessly.

One of the major things to consider is the capacity of the USB flash drive. The capacity can decide how much files and folders you can store in it. If you get a USB Flash drive of smaller capacity, you won’t be able to store enough data on it. When you have a USB flash drive with a small capacity, you will be required to delete your data in the USB drive to free up space for storing other data.

This can be an herculean task as you may go through this over and over again anytime you want to store new data. Hence, selecting a suitable USB flash drive capacity is very important.

Flash drives come in different capacity for example 2GB, 4GB, 8GB, 16GB, 32GB, 64GB, 128GB, 256GB, and so on. The higher the value, the larger the capacity and so also the price. You will always need more in the future. 16GB or 32GB or more is better. Also, the storage is pretty cheap.

Speed in this age and time matters a lot. A USB Flash drive must be fast. Two factors decide the speed of your USB flash drive: USB port itself and the components of the drive.

Read speed: This is the speed at which you will be accessing the files that you copied on to your flash drive. The faster this is, the better. If you are copying large music files or video files you will certainly appreciate the speed.

Write speed: This is the speed at which you will be writing the files on to the drive. The faster it is, the faster your backup will be. If you plan to use the drive to do backups of files or applications often.

Flash drives are sub-categorized in to generations:

  1. USB 2.0

  2. USB 3.0


USB 3.0 is much faster than USB 2.0, but both the USB port itself and the drive itself must support the standard. Please note this “If you use a flash drive of USB 3.0 but the computer's port is USB 2.0, the transfer will take place at the speed of USB 2.0.

The flash drive and controller type inside the stick also has impacts on the speed. The best drives incorporate the advanced controller and memory quality in solid state drives (SSDs), while the cheaper drives use cheaper components that do not perform well (fast) in transferring and storing data.

This is why when you see two similar USB flash drives and both of them of same spec (with USB 3.0 and 32GB capacity) made by two different manufacturers, you would notice that their cost is different.

This is base on the quality of components, which decide the performance of such drive.

We would recommend a minimum write speed of 16 Mb/s or 32MB/s. It is basically always higher by 1.5-2 times. Avoid flash drive with writing speed of 5 MB/s. This is very slow and not to be dabbed into. The USB 3.0 is much faster and you should be looking at something like 100 MB/s.


Size is considered here because of mobility of the Flash drive. It is ok to get a flash drive that is smaller if you plan to carry it around all the time in a key holder or in your pocket. You can get a Flash drive with fold-able design or with a cap to protect the metal part which plugs into the USB port.

Please do not use flash drive which the cap falls off or get loose off all the time. Then again This will protect the drive from wear and tear in most cases. We recommend you go for a flash drive with a simple design. If a flash drive comes out or goes out of the case, or the case turns around it or something else, it is most likely to break sooner or later.

USB Flash drives are made of plastic, metal, wood, and even precious metals. It is important to pay attention to the quality and strength of materials used rather than the appearance. The choice is numerous but be wise.

Another important point to bring to your notice here is that of “shape” of the flash drive. Do not use a flash drive with irregular shape or bogus design. You may not be able place it next to another card (or a device connected into another port) because the ports on a laptop are always located very close to each other.

Do some research before buying on the brand that made such USB Flash drive. Beware of extremely cheap flash drives. Some flash drives are compressed and at the end frustrating when used.

As a rule of thumb, if the spec and properties are not listed on the pack of the flash drive, then it is probably not very good. If they are any good in any of these factors, trust me they will put that on the cover.

We trust that you can now make a choice from the knowledge acquired from this post about USB Flash drives. These points are basic and can be used by anyone in making a choice of flash drive to use.
