Review: Small yet mighty: SanDisk Extreme PRO 256 GB microSD delivers every time - This SanDisk Extreme PRO 256 GB microSD card has been a revelation. Simply slot it into my camera or card reader and it’s instantly ready—no faffing about with drivers. Performance-wise, those advertised read speeds of up to 170 MB/s and write speeds up to 90 MB/s are bang on, so offloading 4K footage or bulk RAW files is ridiculously quick. Build quality feels genuinely premium: it’s shockproof, waterproof, temperature-proof and X-ray-proof, so I have total peace of mind when shooting in the field. Despite its high-end credentials, I’d say it represents excellent value for money—after all, reliability and speedy transfers are priceless when you’re up against deadlines. I’d buy this card again in a heartbeat and wholeheartedly recommend it to anyone wanting a durable, high-performance storage solution that simply works.
Review: Perfect for 4K Dashcam (622GW) and much more - I've been using the SanDisk 256GB Extreme PRO microSD card in my Nextbase 622GW Dashcam and it has performed flawlessly so far (no surprise from SanDisk!) The read and write speeds are perfect for recording 4K video without any lag or dropped frames. I’ve also used it for burst photography on my Cannon 600D DSLR (with the adapter ofcourse), and the card handles large RAW files with no problem. Pros: Real-world speeds are excellent (~170MB/s read, ~90MB/s write) Handles 4K UHD video smoothly Handles 4K UHD + 1080p duel recording from my 622GW A2 rating makes it great for apps on Android devices Durable: water-proof, shock-proof, and temperature resistant Comes with a handy SD adapter Cons: A bit pricier than slower cards, but you get what you pay for Some fake versions exist, so make sure you buy directly from desertcart or a trusted seller I’ve used SanDisk cards for years and they’ve never let me down. If you need a microSD card for action cams, drones, or even your Steam Deck or phone, this is worth the investment.

## Questions & Answers

**Q: Will this work with nextbase dash cam**
A: It's what I have in mine as I didn't fancy paying 60 pound for there own

**Q: Is there any benefit to using the exreme pro card in the switch over the cheaper nintendo licensed sd cards from sandisc?**
A: None. The speed bottle neck in the switch will not be the SD card.

**Q: Has anyone tried these in the steam deck? And if so would you recommend?**
A: Yes I’ve used this in the Steam Deck. Works well for me. I would probably limit the more performance heavy games to the SSD. I think Mortal Kombat X was ok the card and it had some stuttering in cutscenes

**Q: Is this any good for laptop storage or is it overkill?**
A: There are better hard disk options than using a micro sd card
