Lexar Professional 1667x SD Card 256GB

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.

Amazing cards - I use these for video capture on my Fuji XT4. I'm able to film 4k 60FPS at a high bitrate with no aborted recordings. Very high usable capacity and they seem well made. I'll be buying more.

Worked perfectly, would definitely recommend.

I purchased this SD card for use with a GH5, and although it claims to write fast enough, it can't seem to cope with the highest bitrate 4K or 6K. I reccommend purchasing a different SD card if you are using the GH5 professionally, or need the highest quality 4K/6K.Other than that, is a solid SD card, and has been working fine for the 3 months that I've have it for.Consistently seems to achieve 95-100MB/s write speed, and 248-250MB/s read. (Tested using a video file and a SanDisk ImageMate PRO card reader)

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

Nice one. Fast writing and reading rate. Sync with high shutter speed shots. Recommend to buy.

Well, this SD card is a good one given its low cost compared to other brands. I have done some read/write tests and compared it with my old SanDisk v30 UHS-I as seen in the photographs (please note that I have removed the serial no. from the photographs). I have used 100 samples files for read/write and iterated this 15 times and I got the results shown in the photographs, then I compared them to my old SanDisk and you can see the difference..Read speed is almost the same an average of 94MB/s, the write speed was doubled with LeXar which expected and was constant at an average of almost 90MB/s which is not bad.. But of course is not as claimed on the package from the manufacturer which is up to 250 MB/s for read, but it is close enough to the write speed (94MB/s to 120 MB/s).In conclusion this is a good SD card for cameras (Videography) and will not let you down based on the above tests, made in Taiwan and durable. I highly recommend it given its low cost. I would like to test the V90 2000x and see the performance and differences, but it's expensive for me... I hope this review to be helpful.

I bought two of these cards for my FujiFilm X-T5.Although I wouldn't shoot long bursts at 15fps, it is good to know that this card can keep up. Shooting large, fine quality jpegs, along with compressed RAW, each shot produces a total file size of 70.6 MB The camera buffer will hold 23 shots before beginning to slow down. The card empties the buffer pretty quickly. Short high-speed burst should be fine. On 5 or 7 frames per second, there is no slow down.I use the second card as a backup, so the files are being written twice.

Very fast and reliable memory cards. I use these with Sony A7RV for wedding photography

Awesome SD cards.

Got a great deal on these cards , faster readouts

Works perfectly!
