In this video I’m testing a tiny little accessory that actually changes how I shoot and manage files: the Insta360 Quick Reader with a built-in 512GB portable SSD. It’s designed for X5, X4 Air, and Ace Pro 2, and it supports up to 420MB/s transfer speed on the spec sheet. The big idea is simple: faster edit on the go, use it as an external flash drive, and—because it works as a standard USB‑C SSD—you can even record ProRes to it on iPhone, and on Android with apps like Blackmagic Camera. I break the video into sections: unboxing/design, mounting it on X5, X4 Air, and Ace Pro 2 (with the included spacers), plus a mobile workflow demo and a real read/write benchmark on my MacBook Pro. On X5 you’ll want the latest firmware (I’m on 1.9.6) so the camera recognizes the Quick Reader, and it stays fully invisible once mounted with the all‑weather cover. I also show two small accessories I’m using a lot lately: a beautiful foldable magnetic lens cap for X5, and a thinner, sturdier quick release mount system. My main takeaway: it’s a very efficient plug‑and‑play storage solution, but if you use the USB‑C spacer, remember it’s no longer water resistant.
