Lexar Professional 1066x 64GB SDXC UHS-I Memory Card SILVER Series, C10, U3, V30, Full-HD & 4K Video, Up To 160MB/s Read, for DSLR and Mirrorless Cameras (LSD1066064G-BNNNU)

I tried this card on Windows 10 and macOS using AJA System Test. The old Windows 10 machine has 29MB/sec write and 25MB/sec read. The Belkin USB-C 6-in-1 Multiport Adapter has 23MB/sec write and 21MB/sec read on macOS. The DockCase has an impressive 57MB/sec write and 74MB/sec read. The card readers I have cant reach the claimed speed.

These cards just work!

I used this card to replace a 2GB SD card inside my Canon Rebel DSLR. The 2GB SD card I was using did not have enough memory capacity and my wife and I had several instances where we took this camera somewhere, starting taking pictures, but then ran out of memory storage and had to begin deleting photos before taking new photos. Not good! The 2GB card could only hold a couple hundred high-quality photos.

Fast

Surpasses the R/W specs for Sony Cyber-Shot RX100 VII, and even better on sale for 47% off. I liked it so much that I bought another one for my wifes Sony Cyber-Shot HX99.

The first half of the marketing literature claims write speeds up to 120mb/s while the last half claims 70mb/s. When the cards arrived the packaging indeed states 70mb/s. Easy to overlook, but can be disasterous when expecting to deliver real 4K UHD raw footage to a client at 100mb/s. Chance stutters at the 100mb/s write speed is not worth the livelihood gamble. If the literature was more consistent in claims of 70mb/s throughout, I would change my rating. Returning.

Ive been using this for recording video on my 6D Mark II for YouTube videos.

Muy rápida

Have used this brand compact flash for my dslr, so went for it for my corvette pdr as well for performance

Needed this so I could use my digital camera. Works great!
