I can take photos using this and it doesn't seem to slow down the camera fast photo speeds

Great write speed for my camera as the buffer doesn't get full until about 70 shots now!

Excellent speed.

Bought this and love the speed in my D810.

Awesome speed best card

When I used it in a Canon 5D Mk IV the write speed was terrible - I could take no more than 7 shots in a

I'd love to give these a good review, because the write speeds are really great, but the first time I used each card, I had a corrupted file

Great speed!

Higher speed with higher capacity, that is excellent for my Canon 5D Mark III camera.

Great speed and performance

your standard SD card, even the Class 3 cards, only guarantee maybe a 30MB/s minimum write speed

For regular photography, this card's speed is quite nice when coupled with a USB 3.0 card reader.

Awesome speeds on downloading.

Good quality, fast speed

fantastic speed and a great price.

Using this with my Canon 5d and the speed is amazing, keeps up with fast shooting.

This is a great card with excellent speed

Excellent speed and large size.

Otherwise, it is a worthwhile investment and it has allowed me to capture images I previously missed due to slow write speeds.

Fast write speed, the most dependable cards are made by LEXAR

Great price and speed

Speed and safety are really good

Nice high speed CF card at a decent price.

This card has excellent speed and works well in my D800,

Great size and speed

Lexar makes the best CF cards, large capacity & very fast speeds

I like it good speed

Bought this for my DSLR and it works like a beauty the speeds are SUPER-FAST!

The speeds you get for the price are amazing!

Crazy speeds!!

reasonably well it seems the write speed in a 1DX is no better than the 1000x which the tester managed 160 shots in 30 seconds.

Speed is very very slow

I do a lot of birds-in-flight photography that requires fast shutter speeds and fast frame rates in order to capture just the right shot

These are working nicely, good speed in the camera and uploading to the computer.

Awesome speed, but you will fill it fast with a D810.

Nice and fast write speeds.

I wanted to get the best, fastest CF card I could to support that speed and not fail.

No speed issues here for me.

The speed is fast enough to allow continuous shooting of RAW images without buffering while maintaining 1 - 2 images per second if the camera can keep up.

good speed

Good speed up is quick and affordable prices

good speed

I was using an SD card for a while in my 5DM3 until I realized that it doesn't support speeds faster than 333x

so speed in writing is very important

Excellent speed and capacity

Clearing the buffer is much better speed also

The fast write speeds provided better than rated buffer clearance on my Canon 5D Mark IV

Fast speed!!!!

Much better performance over my other, slower-speed (300X-800X), cards.

Great speed great price

Speed is excellent.

awesome speed for continuous shooting!!!!!!!!

Incredible speed.

So if you have the fancy little 95MB/s read and class 3 SD cards, this one is going to give you twice as much "Write" speed.

Lexar states that the 400x is rated at a guaranteed 60MB/s rate, where the 1066x is rated up to 160MB/s

The read speed is the prominent MB/s number on the front of every card (160MB/s on this card).

Great C/P, excellent performance, works fine with my Canon 5D2, 7D2

Atleast its not a wedding I lost, but it could have been

was my new Nikon D-810, but they work just as well in my older olympus body).
