Shooting 8K video fills your memory card much faster than many people expect, and a slow card may drop frames during filming. The Insta360 256GB PRO microSDXC Memory Card is rated V30 with U3 and A2 classifications, so it has sustained write speeds that can keep pace with high-bitrate footage from both an X4 and an Ace Pro.
Head over to Amazon to get the Insta360 256GB PRO microSDXC Memory Card for just $80, down from its usual price of $90. That’s a $10 discount and 11% off.
A memory card that you can store tons of images and videos on
For video, the V30 rating is what truly matters. This rating specifies a minimum sustained write speed of 30MB/s, and the keyword is sustained. Many manufacturers rate their cards based on a short burst of high speed, and in many cases those cards have slowed significantly by the time continuous recording causes them to fall behind.
Rather than shipping a generic card with a logo on it, Insta360 tested this card against its own camera hardware, meaning the X4, the Ace Pro, the GO 3S, and the Flow product line, and it recorded without dropping frames. A memory card failure results in lost footage from an opportunity you can never recapture.
Cameras rarely write one long continuous file and nothing else. The video itself, metadata, thumbnails, and stabilization data all land on the card at the same time in small, scattered pieces. The A2 rating measures how fast the card can handle these small jobs, which is a different job than writing one big block of footage. This pays off later when you pull a full 256GB from the card to your computer, which takes minutes rather than becoming what you leave running while you go eat dinner.
Insta360 put its memory card through the wringer before it ever reached you, testing its ability to endure a wide range of outdoor environments not typically found in offices. To start, Insta360 tested the card’s temperature range by placing it outside at -13°F and inside at 185°F. Beyond extreme heat and cold, the card had to withstand submersion, high-strength magnetic fields, and an X-ray machine test. Whether you’re filming in the snow, recording video while swimming, or carrying your camera through airport security, this card is built with the same level of resistance as the camera itself.
In terms of capacity, 256GB will store several hours of 5.7K footage. I provides a long day of filming at lower resolutions, so you won’t run out of space during a trip. This card works with any camera or device that uses microSD, not just Insta360 equipment, and it includes an SD adapter if you need to use it with a reader that requires a full-size card.
