How to Select an Ideal USB Flash Drive

Since there are many kinds of USB flash drives on the market, how to select an ideal one may be a difficulty for you. Therefore, this part will show you how to select and ideal USB flash drive. It will analyze some important and essential elements when buying a USB flash drive.

If you are bothered by this problem, please pay attention to the following contents. 


First and foremost, you need to check the capacity when purchasing a USB flash drive. The capacity can decide how much files and folders you can store in it. If your USB flash drive capacity is small but you have many data to be stored, it would be not enough.

With a small capacity USB flash drive, you may need to delete your data in the USB drive to free up space for storing other data. This must be terrible news for you. Of course, purchasing an extra-large USB flash drive is not a wise action too. Though it won’t cause a trouble for you, wasting too much space is not advocated.

Hence, selecting a suitable USB flash drive capacity is very important. You need to check the capacity carefully when buying it.


The speed of a USB flash drive also matters a lot. Generally speaking, the faster the USB is, the better. Two factors decide the speed of your USB flash drive: USB port itself and the components of the drive.

Another interesting thing is that when finding two similar USB flash drives and both of them with USB 3.0 and 64GB capacity made by one manufacturer, you may raise a question what makes their costs different? The answer is the quality of components, which decide the performance of your drive.

USB 3.0 is much faster than USB 2.0, but both the USB port itself and the drive itself must support the standard. If your flash drive is USB 3.0 but the computer’s port is USB 2.0, the transfer will take place at a speed of USB 2.0.

The flash drive and controller type inside the stick also has impacts on the speed.

The best drives use the same type of advanced controller and memory quality in solid state drives (SSDs), while the cheaper drives use cheaper components that do not perform well in transferring and storing data.


The performance of a USB flash drive is also essential factor when you are making a choice on USB flash drive purchasing. The USB flash drive’s performance depends on three aspects: the interface, USB mass storage controller and the NAND flash memory chip inside the drive.

Most of USB flash drives apply the standard rectangular Type-A connector, but the controller will support a range of USB standards up to USB3.1. The cheapest drive is limited to USB2.0 with a maximum speed of 40MB/s. USB3.0 can reach speeds of about 625MB/s in theory, while USB3.1 can reach 1,250MB/s.

The actual maximum transmission rate is lower than its theoretical rate – even the fastest USB3.1 only can reach 440MB/s in practice. This is because although USB 3.0 and 3.1 drivers are not hindered by slow interfaces, they are still limited by the speed of the controller and the NAND flash chip itself.

In fact, even the fastest USB flash drives are hard to reach 300MB/s, and most of the peaks are between 100MB / s and 200MB / s when transferring large files in sequence.

Other Factors You Need to Notice

Actually, there are some points you need to keep in mind besides the above elements you. Even though you follow the given instructions, you may still cannot buy an ideal USB flash drive. Firstly, the quality of different brands is various, so a great way is to buy a drive with great reputation.

As there are numerous counterfeit USB flash drives on the market, you’d better buy it in an official flagship store or a physical store. Alternatively, buy the USB flash drive in legal shopping platform such as Amazon, eBay.
