Product Reviews


Lexar is my go to for memory cards... I've never had an issue with them (SD, CF, XQD). They handle read/write as they should and have never given any failures or issues.


I purchased several Lexar for a new camera I was taking to Antarctica. The cards exceeded my expectations - very fast - capturing humpbacks feeding off the front of the ship.- the only way was just to hold the button down and hope everything wrote to the card. Well done..


Fast. Works as expected, not a single issue with using these over a year and capturing thousands of images with them. Even ran them through the washer and dryer once. Still works.


I use myself and resell these cards, began to sale 3 years ago and no problems with them within this period. Recommended to use by anyone from beginner to professional photographers


I got it for my new Canon 5d mark 4 which takes 30 mega pixel pictures and 4k videos. Before this I had an old 16 gb cf card which has x150 and it wasn't be able to record 4k cideos but this memory with speed of 1000x is great. I am happy for choosing it.


No problems yet or expected. Works as advertised. Will buy again.


Proven fast and reliable after a few thousand exposures.


Works fine no problems


Fast enough that my Canons can exceed the listed buffer-limited # of shots when in high speed drive. Never had a failure on a Lexar card; CF or SD. I only use Lexar memory, so my card wallet looks nice when I open it up. Gold CFs and silver SDs.


I LIKE IT very much
