10 best usb flash drives

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

Flash drives, or USB drives – are convenient storage media, thanks to which you can transfer files from one computer to another in the simplest way. However, when choosing such an accessory, it is advisable to take into account many parameters that will determine the ease of use. To make it easier to find the right drive, we've compiled a list of the best flash drives.

What you need to know when choosing a flash drive

Choosing a flash drive is not as easy as it seems. Of course, if you plan to use the drive mainly for transferring documents, you can take the first one that comes across (or the most beautiful one). But if it will store large files or multimedia with high bitrate – movies in resolution Full HD, for example – then the choice should be approached responsibly.

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

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

  2. In 2018, flash drives with a USB Type-C connector are becoming more and more popular. This is an oval, symmetrical connector. This connector is used in flagship smartphones, ultrabooks and hybrid laptops. For example, the MacBook Pro 2017 uses only USB Type-C, so you can't install a 'regular' flash drive into it.

  3. Micro USB is an increasingly outdated standard. It is used in smartphones and ultra-budget hybrid laptops. If you plan to work on the go and open files from a flash drive on a mobile device, you should purchase a drive with two connectors: USB Type-A and Micro USB.

There are adapters between the connectors, as well as flash drives equipped with two connectors at once.

USB Generation (1.1, 2.0, 3.0, 3.1)

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

  1. USB 1.1 – up to 12 Mbps;

  2. USB 2.0 – up to 480 Mbps;

  3. USB 3.0 – up to 5 Gb / s;

  4. USB 3.2 – up to 20 Gbps.

It is self-evident that if you plan to copy a large amount of information to or from a USB flash drive (several GB at a time), then it is better not to skimp and take a USB 3.0 or 3.1 drive. For documents, small files, etc. less new generations will do as well.

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

Actual data volume

The actual capacity of the flash drive is always less than the one indicated on the package. This is not only a marketing ploy, but also a 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 consequence, the actual data volume is always less than the nominal one. And if you plan to store 30 GB of information on a flash drive, then a 32 GB drive will no longer work – you need to take 64 GB.

The real capacities of the flash drives are indicated below:

1 GB drive – actually 0.95 GB;

  1. 4 GB – 3.72 GB;

  2. 16 GB – 14.9 GB;

  3. 32 GB – 29.8 GB;

  4. 64 GB – 59.6 GB.

Actual baud rate

The actual data transfer rate is influenced by two factors:

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

  2. The second is the minimum USB generation. If you insert a 3.0 'fast' USB stick into slow port 1.1, the maximum baud rate will be limited to the speed of port 1.1. Conversely, if you insert a slow 1.1 USB stick into port 3.0, the transfer rate will be limited to the 1.1 drive speed.

This is important to consider when buying a flash drive. If you plan to use a drive to record movies on it from a computer and play them later on a TV, and both of these devices are equipped with USB 2.0, you should not purchase a 3.0 drive – a pointless overpayment.

Body material

This parameter should be taken into account if you are purchasing a high-speed USB 3.0 flash drive or you plan to use the future drive very actively (for example, for ReadyBoost technology). The flash drive heats up noticeably during fast recording. 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 heatsink, cooling the drive and extending the life of the device.

For slow or rarely used flash drives, this parameter does not really matter, any material or case design will do.

Why first place: High speed data transfer, hardware encryption.

Description: 64-gigabyte configuration of the flash drive, which took first place in the rating of drives with a capacity of up to 32 GB. Like its 'little brother', this model offers high read and write speeds – up to 40 megabytes per second and up to 135 megabytes per second, respectively; USB 3.0 interface; dense metal case and hardware protection.

Data protection is implemented through hardware encryption – all files on the drive are encrypted, and you can access them only after entering a password. The corresponding software comes with the flash drive and runs on the most popular operating systems: Windows and Mac OS.

Like other flash-drive SSDs, this model is initially broken down into megabyte segments. Therefore, if you plan to store small files on it, it is advisable to format it immediately after purchase by setting the sector sizes standard for the required FS.

The body of the flash drive is made of plastic and is devoid of gaskets that protect against moisture or dust. In addition, the outer shell is covered with a soft touch material that is pleasant to the touch.


  • Maximum data transfer rate;

  • Low heating during operation;

  • Plastic, pleasant to the touch.


  • Comparatively slow recording in random access mode;

  • Soft-touch coating 'collects' dust and lint;

The best high-capacity flash drives

Kingston DataTraveler Ultimate GT 1TB

Rating: 4.9

Kingston DataTraveler Ultimate GT 1TB

Why first place: Terabyte flash drive.

Description: The terabyte drive Kingston DataTraveler Ultimate GT is based on SSD technology, which allowed developers to fit 1024 GB of internal memory into a compact case and provide high read and write speeds. In particular, sequential copying of data to it is carried out at 200 megabytes per second, and from it – at 300 megabytes. To ensure this speed, the USB 3.1 protocol is used.

The flash drive does not support hardware encryption, as it requires frequent segment rewriting, which is critical for SSD drives. The body of the device is made of metal with plastic inserts. The connector is retractable, and the extraction mechanism is implemented very reliably and will not fail even after many years of use.

The flash drive takes the first place in the rating precisely because of its large volume – only SanDisk managed to surpass 1 TB, but these of its drives are practically not found on sale.


  • Maximum built-in memory;

  • High data transfer rate;

  • Minimum heating during operation.


  • Out-of-the-box markup into 1 MB segments, so it is advisable to format if you plan to store small files;

  • No protection against water and dust;

  • No hardware encryption.

HyperX Savage 512GB

Rating: 4.8

HyperX Savage 512GB

Why the second place: 512 GB – half of the leader of the rating.

Description: Another SSD-drive in flash drive format. All HyperX Savage branded devices share the same specifications. Therefore, like the 128GB version, the 512GB model has sequential writes at 250MB / s and reads at 350MB / s. Random access (for example, when copying small files), a little slower, but still at the level of USB 3.1 interface speeds.

Similar to the 128GB version, this flash drive does not support hardware encryption due to the limitations of SSD technology on the number of sector rewrites and is performed in a plastic case with a soft touch coating. Out of the box, the segment size is 1 MB, so for storing small files it is better to format it with other cluster parameters.


  • Maximum read and write speed;

  • Body pleasant to the touch;

  • Low heating during operation.


  • Heavy and bulky;

  • Needs formatting;

  • Low speed when writing small files.
