A memory stick is a small compact device to store digital data, with a similar weight and size to a house key. They are a very cost-effective way of adding simple extra storage to a computer. Primarily memory sticks are used for transferring data from one device to another.

For maximum compatibility between devices, format the memory stick in exFAT. This will ensure it's compatible with Apple macOS and Windows operating systems. Prices vary, but you can expect to pay from £4 for a 16Gb stick to £35 for a 256Gb stick. Memory sticks can look identical but offer significantly different performances. Make sure you compare the transfer speed when comparing prices.

Memory sticks are also referred to as thumb drives, pen drives, flash drives and USB sticks.
