How to Choose a USB Flash Drive That Is Worth Using

Many people are quick to ask this question: “What is the best brand of USB flash drives?” Nevertheless, in choosing a USB flash drive, the purpose for which you want to use the USB stick is more important than the brand.

Here are some factors to consider when choosing a USB drive:

#1 Storage Capacity

If you’re looking for the largest flash drive available in 2021, then it’s possible that you handle large files and folders. Although most USB drives typically fall into the 8GB - 256GB size range, you can always get those that offer up to 512 GB - 1 TB.

#2 Transfer Speeds

File transfer speeds depend on the specifications of the USB drive and those of the computer. However, fast USB flash drives offer up to 400MB/s read speeds and 300MB/s write speeds. When on a small budget, many people opt for USB drives that offer 150MB/s - 300MB/s read speeds and are still suitable for their use case. Although read and write speeds are an important factor to consider, faster USB drives are more expensive than slower sticks.

#3 Connector

Most of the large USB drives only come with the standard USB 3.0 connector. USB 2.0 connectors are now older, slower, and only suitable for smaller capacities. Although more devices are gradually moving over to USB-C ports, there are only a few flash drives that use USB-C connectors. Nevertheless, it’s advisable to give attention to this fact when purchasing your USB drive.
