Memory Cards

Memory cards offer compact, removable storage for cameras, recorders, and portable devices. This category includes cards used for capturing photos and video, transferring files, and expanding device storage.

In everyday use, reliability and speed matter more than size alone. Buyers often check which format their device supports, then choose based on capacity and speed ratings suited to their workload. For video and burst photography, consistent performance is especially important.

For portable devices and media capture, memory cards provide a convenient and dependable way to store data.

MicroSD Memory Cards - Express

Memory cards are a type of portable flash storage device that are commonly used in portable electronic devices such as digital cameras, some mobile phones and various handheld devices.

These MicroSD cards are segregated by their bus speed - either High Speed or Ultra High Speed (UHS) - this defines the maximum throughput speed of the card; UHS I or U1 - 104MB/s; UHS II or U2 - 312MB/s; and UHS III or U3 - 624MB/s.

They are then broken down into size groups - MicroSDHC (High Capacity up to 32GB ), MicroSDXC (Extended capacity up to 512GB) and are denoted with ‘speed class’ or ‘video class’ ratings of C10 or V10 (up to 10MB/s), V30 (up to 30MB/s), V60 (up to 60MB/s) and V90 (up to 90MB/s), which define their minimum sequential write speeds for higher performance cards.
