I bought the SanDisk 1TB Extreme microSDXC Card to expand the storage on my GoPro and laptop, and it’s been nothing short of excellent. If you’re looking for massive capacity, high speed, and reliability for video recording or file storage, this is a brilliant choice.First off, the packaging is simple but effective — you get the microSD card itself and a full-size SD adapter, which is useful for cameras, laptops, or card readers that require standard SD slots.The card is rated A2, V30, U3, and Class 10, meaning it’s certified for extremely fast application performance, consistent 4K video recording, and general read/write speeds suitable for intensive use. I ran a few tests and got read speeds around 160MB/s and write speeds around 90MB/s — which matches the manufacturer’s claims and makes it ideal for high-res video capture.I’ve used it extensively in a GoPro Hero 10 for recording 4K60 footage, and there were no skipped frames, buffering issues, or corrupted files. It handled over three hours of continuous high-quality video recording without any problem, which is exactly what you want when you're out adventuring and can't afford to lose footage.The card is shockproof, waterproof, temperature proof, and X-ray proof, which gives extra peace of mind for travelling. I’ve taken it hiking in wet weather, exposed it to airport scanners, and even dropped it once (oops), and it’s still performing perfectly.The 1TB capacity is massive. You can store literally hundreds of hours of HD or 4K video, tens of thousands of photos, or countless apps and documents — all without worrying about running out of space. It’s also brilliant for expanding the storage of smartphones or tablets that support expandable memory.The SD adapter is sturdy and allows easy file transfers to laptops or desktop computers without needing a separate card reader.If I had one small caution, it’s that you need to ensure your device can actually handle 1TB microSD cards — older devices might not support cards above 512GB, so double-check first.Overall, the SanDisk 1TB Extreme card is everything you want: fast, reliable, rugged, and absolutely enormous. Highly recommended for photographers, videographers, content creators, and heavy mobile users!

I've always used SanDisk memory cards in my stills and video cameras, since way back when they were CF sized, and they've always performed falwlessy. It's definitely worth paying the wee bit extra over no-name brands.These Extreme cards will handle filming 4k video at 60fps continuously for longer than your camera battery will last. I've not tried at higher framerates other than short bursts, but they were fine with this too.One thing I'd advise is to always buy SanDisk direct from Amazon. Unfortnately there are a lot of fake SanDisk cards out there and I've heard of people being burned by this. So I'd always buy from a reputable seller with a solid returns poolicy... just in case.

Sandisk have been my go to for decades, great quality and capacity for the price, would always trust with my date just make sure its sold by amazon have a fake units in the past that came from other vendors, easy to use never have issues with cards not being not showing up on my computer. Use them in action cams drones never had a issue with video or sound.
