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)

Solid memory card for 5D Mark IV , Running strong from years. Never gave up on me. It is a well made and professional grade card.

This is a great fast card for my camera. Good storage and most of all, the price is great! Ive had no issues. Ive purchased 2 of them

Theres only so much to say about a memory card. This card is from a reputable brand thats been around the industry for a while, a good amount of storage to keep you going for a whole shoot, and solid read and write speeds. I have a couple other bronze branded Lexar memory cards and this card definitely reads faster. I havent noticed any write speed differences which is fine since both write well above what their ratings suggest.

Que buena inversión; tengo más espacio para almacenar y trabajar de seguido sin necesidad de cambiar la tarjeta.

These cards are fast for the money . Not much else to say.

Best card for my Sony a6400 great writing for 4k 24fps video

In my pro opinion, these disks are as good as San Disk Extreme Pro. Im an award winning photographer and I depend on good gear including what Im shooting on. I like these Lexar Professional 1066x 64GB disks because they are flawless and Ive never had issue with any of them throughout my career. Ill continue buying these as part of my arsenal.

This is a good card but not a spectacular card. I didn’t note much improvement in read and write speeds. Lexmark is a name brand but not like Samsung. So this card gives you what you expect but no over the top performance.

I have used Lexar SD cards for many years (among others) and have been fine with them. Not the absolute best, but quite decent, and often very reasonably priced. That is the case here. Look at the price! For the price asked this is a good value. The performance is fine. I dont nitpick the speeds, but I do expect them to be close to the specs and that seems to be the case here. The packaging was good, the cards build quality is good, and the card performs as expected. Thats good enough for me. The real win here is that you are getting a good quality card for the price of some lesser quality brands and thats a win!

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.
