What is flash memory used for?+
Flash memory stores files without a constant power supply, making it useful in cards, USB drives and portable SSDs.
What is the difference between an SD card and a microSD card?+
An SD card is larger, while a microSD card is smaller and commonly used in phones, action cameras and compact devices.
How much capacity do I need?+
Choose smaller capacities for documents and occasional transfers, and larger capacities for photos, video and regular backups.
Do I need a fast card for video?+
If you record video or shoot bursts of photos, a faster card is usually the safer choice for smoother performance.
Can I use a USB flash drive on any device?+
Only if the device has a compatible USB port and supports the file system or adapter you plan to use.
When should I choose a portable SSD instead of a USB stick?+
Choose a portable SSD when you want faster transfers, more consistent performance or better handling of large files.
