TEAMGROUP ELITE A1 microSDXC 256GB Memory Card, Class 10 UHS-I U3 V30 A1, up to 100 MB/s Read, with SD Adapter

The TEAMGROUP ELITE A1 256GB (TEAUSDX256GIV30A103) is a microSDXC memory card rated Class 10, UHS-I U3, V30 and A1, with up to 100 MB/s read and 50 MB/s write, for smartphones, tablets, handheld consoles, action cameras and drones that record 4K. An SD adapter is included for cameras and laptops with a full-size SD slot.

It is a capacity-first card: 256GB at a sensible price, with the V30 rating 4K devices ask for. The 50 MB/s write is comfortably above the 30 MB/s V30 minimum, but slower than premium cards when you shoot long bursts. Note the operating range of 0°C to 70°C — narrower than many rivals.

• 1 × TEAMGROUP ELITE A1 microSDXC card, 256GB
• 1 × microSD-to-SD adapter

• V30 / U3 means a guaranteed minimum sustained write of 30 MB/s — the rating most 4K cameras, drones and action cameras ask for.
• A1 (min. 1500 read / 500 write IOPS) means apps installed on the card in Android open and run at an acceptable speed.
• The up to 100 MB/s read figure is the maximum measured by TEAMGROUP with a fast host; in a USB 2.0 reader or an older device real speed is much lower.
• Usable capacity is a little below 256GB because part of the card is used for formatting and management — this is normal for every memory card.
• It comes formatted as exFAT. For best reliability, format it once in the device that will use it (camera, phone, recorder) before the first recording.

• Devices limited to SDHC (32 GB maximum) — they will not recognise the card.
• UHS-II speeds — this is a UHS-I card; UHS-II cameras and readers run it at UHS-I speed.
• Use below freezing (for example a dashcam or outdoor camera in winter conditions) — the rated operating range starts at 0°C.
