Available in 1.9TB, 2TB, 4TB and 5TB capacities these SATA III 6Gb/s SSDs may no longer be the fastest around thanks to emerging PCIe SSDs, but they're the most cost-effective and are still easily fast enough for most users. You'll need a spare SATA 6Gb/s port to get the most from them, and a 2.5" capable drive bay - an adaptor may need to be bought, but most cases have at least one. These drives are the highest capacity ones available, suitable for holding an operating system, as well as numerous programs and a healthy collection of media and games.

MicroSD memory cards expand the file storage of mobile devices such as cameras and phones and other devices with a MicroSD slot.

These particular MicroSD cards are rated as up to UHS-I Class 3 (U3), meaning they can write at up to 30MB/sec making them suitable for recording 4K or FullHD (1080p) video at 60 - 120fps and high resolution photos. Some of these cards are also rated as V30 Video Speed, labelling them as being optimised for video recording.

Some cards even feature an Application Performance Class, making them ideal for use with devices such as tablets & smartphones. Cards labelled A1 provide a minimum of 1.5k Read & 0.5k Write IOPS, while A2 labelled cards push random performance even further with a minimum of 4k Read & 2k Write IOPS.

A solid state memory card, Compact Flash is a small removable mass storage device that uses flash memory technology. These cards as with all flash storage will retain data indefinitely. They are popular in the higher end specialist applications such as various digital cameras, tapeless video recorders, data logging and compact recording devices for example. Note that Compact Flash are not are not physically or electrically the same as CFast cards.

These portable memory card readers and writers use a USB interface to connect with a computers USB port. These devices can accept a range of memory cards/sticks that simply plug in and are ready to be accessed. These card readers / writers allow simple and quick transfer of music, photo, video and data files to and from a flash memory card.
Updated

The latest revision of the USB standard, version 3.1, doubles the theoretical speed from 5Gbit/s or 625MB/sec to 10Gbit/s or 1,250MB/sec, meaning much quicker data transfers when copying files to and from a USB device such as a pendrive. USB 3.1 devices are backwards compatible with USB 3 and USB 2 ports, but you'll need a motherboard or add-in card that supports USB 3.1 to get the full advantage of the new standard.

MicroSD memory cards expand the file storage of mobile devices such as cameras and phones and other devices with a MicroSD slot.

These high performance MicroSD cards are rated as Class V60 & above, which in addition to being UHS-II compliant, means they are optimised for video recording & can write at over 60MB/sec making them particularly suited for capturing 4K and 8K videos at 60 - 120fps.

SD memory cards expand the file storage of electronic devices such as video cameras, digital stills cameras, mp3 music players & even some computer systems with a SD slot.

External SSDs are ideal for users looking for lightweight, portable and speedy storage. Their pocket-friendly enclosures are significantly smaller and lighter than external hard drives, and with no moving parts they're also silent, more robust and less prone to physical shock damage. They use the USB 3 interface, which is 10 times faster than and backwards compatible with USB 2.

USB 3.0 offers up to 5Gbps transfer speeds, along with being backward compatible with USB 2.0 ports. These compact USB Flash Drives / Pen Drives / Memory Sticks are the ultimate in personal data storage. Look out for advanced features such as a ring attachment point for a keyring/lanyard, weather resistant construction, encryption/security and capless design.
