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.
