Flash drives, or USB drives, are convenient storage media that allow you to transfer files from one computer to another in the most convenient way. in a simple way. However, when choosing such an accessory, it is advisable to take into account many parameters that will determine ease of use. To make your search for a suitable drive easier, we have compiled a rating of the best flash drives.

What you should know when choosing a flash drive

Choosing a flash drive is not as simple as it seems. Of course, if you plan to use the drive mainly for transferring documents, you can take the first one you come across (or the most beautiful one). But if they are stored on it large files or multimedia with a high bitrate - movies in Full HD resolution, for example - then you should approach the choice responsibly.

Flash drive connectors (USB Type-C, USB Type-A, Micro USB)

    The flash drive connector determines the hardware compatibility of this drive with the computer. The most popular standard is USB Type-A. This is a classic 4-pin connector rectangular shape, which is used in almost all computers.

    In 2018, flash drives with a USB Type-C connector are becoming increasingly popular. This is an oval, symmetrical connector. Flagship smartphones, ultrabooks and hybrid laptops are equipped with this connector. For example, in MacBook Pro 2017 only uses USB Type-C, so you can’t install a “regular” flash drive in it.

    Micro USB is a gradually becoming obsolete standard. It is used in smartphones and ultra-low-cost hybrid laptops. If you plan to work on the go and open files from a flash drive on mobile device– it’s worth purchasing a drive with two connectors: USB Type-A and Micro USB.

Adapters between connectors exist, as well as flash drives equipped with two connectors at once.

USB generation (1.1, 2.0, 3.0, 3.1)

Maximum speed data transfer to and from a flash drive is determined not only by the performance of the built-in drive itself, but also by the generation of USB used. So, the limit values ​​are as follows:

    USB 1.1 – up to 12 Mbit/s;

    USB 2.0 – up to 480 Mbit/s;

    USB 3.0 – up to 5 Gbps;

    USB 3.2 – up to 20 Gbps.

It is self-evident that if you plan to copy to or from a flash drive a large number of information (several GB at a time), then it’s better not to skimp and take USB drive 3.0 or 3.1. For documents, small files, etc. Less recent generations will also fit.

By the way, USB 3.2 is only supported on USB Type-C.

Actual data volume

The actual capacity of a flash drive is always less than that indicated on the packaging. This is not only a marketing technique, but also technological feature. Flash drive manufacturers believe that 1000 bytes is 1 kilobyte. The operating system is sure of something else - 1 kilobyte is equal to 1024 bytes.

As a result, the actual amount of data is always less than the nominal amount. And if you plan to store 30 GB of information on a flash drive, then a 32 GB drive will no longer be suitable - you need to take a 64 GB one.

The actual capacities of flash drives are listed below:

A 1 GB drive is actually 0.95 GB;

    For 4 GB – 3.72 GB;

    For 16 GB – 14.9 GB;

    For 32 GB – 29.8 GB;

    For 64 GB – 59.6 GB.

Actual data transfer rate

Two factors affect the actual data transfer speed:

    The first is drive performance. This parameter varies between models (and often copies of the same series) of flash drives, and it can only be calculated experimentally.

    The second is the minimum generation of USB. If you insert a “fast” 3.0 flash drive into a slow 1.1 port, the maximum transfer speed will be limited by the speed of port 1.1. Conversely, if you insert a slow 1.1 flash drive into a 3.0 port, the transfer speed will be limited by the speed of the 1.1 drive.

This is important to consider when purchasing a flash drive. If you plan to use the drive to record movies on it from a computer and then play it on a TV, and both devices are equipped with USB 2.0, you should not purchase a 3.0 drive - it’s a pointless overpayment.

Housing material

This parameter is worth considering if you purchase a high-speed USB flash drive 3.0 or a future drive is planned to be used very actively (for example, for ReadyBoost technology). When writing quickly, the flash drive becomes noticeably hot. And this heat needs to be removed somehow.

The best option is to buy a flash drive in a metal case. It acts as a radiator, cooling the drive and extending the life of the device.

For slow or rarely used flash drives, this option special significance does not have, any material or design of the case will do.
