Best 64GB USB drive

Capacity: 64GB | Interface: USB 3.0

Good value

Plenty of space

Not as fast as other USB 3.0 flash drives

For the best USB flash drives, the cost of postage and packaging actually constitute more of the price than the USB stick itself. However, this incredibly compact and affordable drive is more than worth the cost of shipping.

The Kingston Technology DataTraveler 100 Generation 3 is the most affordable 64GB USB 3.0 drive on the market with read/write speeds of 150Mbps and 70Mbps respectively.

SanDisk Extreme CZ80

3. SanDisk Extreme CZ80 USB flash drive

Fast, reliable and cheap

Capacity: 32GB | Interface: USB 3.0



Not quite the fastest stick out there

One of the best USB flash drives is the brilliantly priced SanDisk Extreme CZ80. It offers plenty of storage space and quick file transfer speeds. Although it’s priced more towards the budget end of USB sticks, the performance is anything but budget – this is a very speedy little performer. 

The slide-out design of this stick means you can tuck the USB interface into the body when not in use, minimizing the risk of it getting damaged when you’re carrying it around.

Verbatim Pinstripe

4. Verbatim Pinstripe USB flash drive

Best 128GB USB drive

High capacity

Good price

Not the most robust drive

Not very fast

This is the cheapest USB 3.0 drive on the market per GB. It comes with a two-year warranty and a capless/retractable cap design. 

It’s worth noting that Verbatim – a very well-known Japanese storage and memory manufacturer – sells it on its website and often has pretty good deals on the device.

6. Patriot Viper Fang

Large storage space for gamers

Capacity: 128GB – 1TB | Interface: USB 3.1



Not as fast

The Patriot Supersonic is a USB 3.1 drive (compatible with USB 3.0 and 2.0) from one of the most established memory players on the market, but a relative newcomer to this segment. It has a zinc alloy body with aluminum accent and reaches read/write speeds of 380Mbps and 70Mbps respectively, which is no slouch. Not only that, but it comes with a five-year warranty.

Samsung T3 SSD

7. Samsung T3 SSD USB flash drive

Best 1TB USB Drive

Capacity: 1TB | Interface: USB 3.1

Very good performance

Very high capacity


We’re solidly in premium territory with one of the best USB flash drives, the Samsung T3. Not only does it offer absurdly high read speeds of up to 450Mbps thanks to Samsung’s own 3D V-NAND technology, it also comes with a three-year warranty and has a USB Type C connector. Note that it is much bigger than a traditional flash drive and costs about five times a traditional hard drive of a similar capacity.

In comparison, a 1TB SSD like the Samsung EVO 850 costs just £240. It comes with V-NAND like the Samsung Portable T1 and it does boast speeds of 530Mbps and 520Mbps in read/write mode respectively. Note that you will need to get a separate enclosure to get it to work with a standard USB port.

SanDisk Ultra Fit CZ43

8. SanDisk Ultra Fit CZ43 USB flash drive

Small and unobtrusive

Capacity: 32GB | Interface: USB 3.0

Compact and portable


Not very fast

If you don’t want a USB stick jutting out the side of your laptop or tablet while you use it, then a low profile USB stick is a good choice, and the SanDisk Ultra Fit CZ43 is an excellent choice. It’s small and light enough to easily carry around, and when it’s plugged into your laptop it doesn’t stick out much from the body.

It’s also very cheap, at around £10 for the 32GB version, with 64GB and 128GB versions also available. It’s not quite as fast as many of the best USB flash drives we mentioned here, but if you want a small form factor USB stick, it’s worth the trade-off.

How to choose your USB memory sticks?

  • It’s not worth looking for memory sticks smaller than 64GB simply because the price difference you pay for two or four times the storage is tiny.
  • Make sure you include delivery price when doing the numbers as quite often you end up paying more for the postage than the drive itself, particularly for low cost models.
  • USB 2.0 is sufficient for smaller capacities but not for bigger ones where write speeds can get sluggish. Larger flash drives (128GB or more) often come only with a USB 3.0 connector.
  • If you plan on moving files to and from portable devices (tablets or smartphones), consider a memory stick with a microUSB connector and a full-size USB one.
  • Avoid buying your memory sticks from vendors with little feedback on auction websites as these drives might turn out to be fake. All the vendors listed are tried and trusted ones.
  • Above 128GB, you might want to consider a SSD if you want ruggedness, portability, versatility and better performance without the cost.
  • Note that the capacities are likely to be lower than stated when they are formatted and mounted on an operating system.
