What You Should Know about 64GB USB Flash Drives

A USB flash drive is a small device that fits into the palm of your hand and allows you to create backups, update the firmware, and generally store or transport data. The device consists of an internal flash memory surrounded by a tough exterior and a retractable USB plug. These drives, available on eBay, hold 64GB of data.

How do you choose the right 64GB USB flash drive?

The quality of the 64GB USB flash drive can be generally defined by the following features.

  • Data transfer rate: The data transfer rate is mostly determined by the read-and-write rate of the drive, which can vary based on the manufacturer. However, the USB that is used limits the version. A USB 2.0 drive has a maximum possible transfer speed of 480 megabits per second. A USB 3.0 drive, however, has a maximum transfer speed of 5 gigabits per second. Actual real-world performance may be somewhat lower.
  • Type of USB: USB Type A is the most common USB connection. It is the type of USB port found on all desktop and laptop computers. Another common type of USB connection is USB Type C. It has become standard in smartphones and tablets since around 2014. The two types are not compatible with each other unless you use an adapter. Most USB drives have one or the other (mostly Type A). However, a select few USB drives have both Type A and Type C plugs built in.
  • Durability: USB flash drives typically come with plastic or metal. Some models are resistant to water, electrical shocks, and extreme temperatures.
  • Security: Some flash drives feature AES hardware encryption right out of the box.
Are different versions of USB compatible with each other?

At least in USB Type A, compatibility is simple and straightforward. A USB 2.0 Type A drive connects with a USB 3.0 port and vice versa, but it only operates at the speed of the slowest version. Therefore, it is a good idea to match them together.

What is a flash drive?

A flash drive, as the name implies, contains flash memory. That is the same type of technology that appears in solid-state drives and memory cards. Flash memory can be erased and reprogrammed electronically. Because it contains no mechanical parts, a flash drive is small, highly portable, and resistant to physical shocks or disruptions. The memory can read and write quickly. These factors make it suitable for small drives that require minimal space.
