Lexar Professional 1667x SD Card 256GB, SDXC UHS-II Memory Card, Up to 250MB/s Read, 120MB/s Write, Class 10, U3, V60 SD for Professional Photographer, Videographer, Enthusiast

Fast write speed. Use for photos and video - no corruption!

I bought the Lexar Professional 1667x 128GB SD card as a second card for my Canon R7, aiming for something budget-friendly but still fast enough for hybrid shooting. This card uses the UHS-II interface, which means it has a second row of electrical contacts for faster data transfer. According to Lexar, it offers read speeds up to 250MB/s and write speeds up to 120MB/s, impressive specs for the price. At the time of purchase, I paid £26.59, which felt like a steal for a UHS-II card. I had considered a similar option from Prograde, but ultimately chose Lexar because of the limited lifetime warranty. Packaging: The card comes in a simple flat cardboard sleeve with a clear plastic window to view the product. You’ll need to cut open the top to access the card, so it’s not resealable or reusable, but that’s typical for SD card packaging at this price point. Performance: I tested this card extensively in both photo and video modes on the Canon R7. In photo mode, it cleared the buffer of 31 RAW images in about 10 seconds, which is decent, not the fastest, but more than adequate for most users. For video, I recorded in 4K 25fps 10-bit C-Log 3, and the card handled it flawlessly. On the R7, this card can store approximately 1 hour and 35 minutes of footage at that setting, which is great for longer shoots without needing to swap cards. Warranty: Lexar includes a limited lifetime warranty, which covers replacement if the card fails due to manufacturing defects or normal use. However, it’s worth noting that data recovery is not included, so always back up your footage regularly. Final Thoughts: This card is a fantastic value for beginner to mid-range shooters, and even some professionals who don’t need the absolute fastest speeds. If you’re shooting high-bitrate RAW video or ultra-high-resolution stills, you might want to invest in a higher-tier card for peace of mind. But for most hybrid shooters, this Lexar 1667x hits a sweet spot between performance, reliability, and affordability.

My camera has dual card slots, and I bought two of these when I first got the camera. Finding I wanted another card, I didn't hesitate, but bought the exact same type, i.e., this card. I have always found them very capable and reliable, and for my purposes seem to have a great write speed, enabling me to save fast bursts of photographs with no buffering problems. The capacity is also amazing. I upload my shots to my computer and then clear the cards, ready for the next shoot, but honestly, while I do not do much video, for photographs I cannot imagine a scenario where I would ever run out of space, be that on a professional shoot or even if I took my camera on holiday and left my computer at home. Yes, I could probably get by with a lower capacity card, but in doing so, I would lose some of that reassurance. I think these are great value for money. Personally, I think

Good cards, could be cheaper.

Really solid SD cards. Tested on numerous jobs with my Canon C70 shooting 4K 12bit RAW. Although the cards are technically under-specced for what I need, I haven't had a single issue or dropped frame across hours of recording the past couple of months. Well worth the money!

Super fast SD card with reliable performance. Perfect for 4K video and burst photography without lag. 128GB offers plenty of storage and the build feels solid. Great choice for professional and enthusiast photographers.

Reliable, hasn't faulted me in months of use. Hope it will last a long time, since it wasn't the cheapest on the market I hope it turns out to be a good investment

Great cards…purchased the twin pack of these in October 2025 (x2 64GB) for £31.99 but now they are £127!?!? Shame the price has risen so much. If you are considering buying them, they really are fantastic & I’ve been using Lexar for many years now but please wait for them to come back down in price first! 📷
