Kingston Canvas Go! Plus microSDXC 64GB Memory Card, Class 10 UHS-I U3 V30 A2, up to 200 MB/s Read, Card Only, no Adapter

The Kingston Canvas Go! Plus 64GB (SDCG4/64GBSP) is a microSDXC memory card rated Class 10, UHS-I U3, V30 and A2, with up to 200 MB/s read and 100 MB/s write, for action cameras, drones, 4K-capable phones and handheld consoles. This is the single-pack version without an SD adapter, meant to live permanently in a microSD slot.

The U3 / V30 rating is what matters for video: it guarantees the sustained write that 4K recording needs, so the camera does not drop frames or stop. The 200 MB/s read figure is a Kingston measurement with its own MobileLite Plus reader; in ordinary UHS-I readers expect roughly half of that when you offload footage.

• 1 × Kingston Canvas Go! Plus microSDXC card, 64GB
• No SD adapter (card only)

• V30 / U3 means a guaranteed minimum sustained write of 30 MB/s — the rating most 4K cameras, drones and action cameras ask for.
• A2 (min. 4000 read / 2000 write IOPS) helps when apps run from the card on Android; the full A2 benefit needs a phone or tablet that supports A2, otherwise it behaves like A1.
• The up to 200 MB/s read figure is the maximum measured by Kingston with a fast host (200 MB/s needs the Kingston MobileLite Plus reader; standard UHS-I readers top out around 100 MB/s); in a USB 2.0 reader or an older device real speed is much lower.
• Usable capacity is a little below 64GB 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.
• 64GB holds roughly an hour or more of 4K footage depending on the bitrate of your camera — for long trips or high-bitrate drones consider a larger card.

• Devices limited to SDHC (32 GB maximum) — they will not recognise the card.
• Full-size SD slots without a separate adapter — the card fits only microSD slots.
• UHS-II speeds — this is a UHS-I card; UHS-II cameras and readers run it at UHS-I speed.
