Customer Reviews

Make sure you have a UDMA camera
First off...make sure you have a UDMA compliant camera or you will be spending extra money that won't offer any benefit. If you're camrea doesn't supprt UDMA, don't come back here and whine that it's slow. In fact it may cause problems but from what I've read those are few and far between.

Secondly, the Extreme IV is actually rated at 45MB/s now (UDMA). If you order a card and it's not 45MB/s, send it back as it's old stock.

As for the performance of the card, it's a perfect match for my 50D. I use a number of them while shooting sporting events and they keep up just fine with the 6.3 FPS the 50D can do. Never had one fail on me even in less than perfect conditions.

If you have a UDMA compliant camera, give this card a shot. If you don't have a UDMA compliant camera, go for the Exteme III.

SanDisk EXT IV 8gb
I am very happy with this card. It has the speed and has the space to hold the raw pictures that I seem to be taking more and more.

Fast and Reliable
I ordered my first Sandisk Extreme 4 along with the Firewire reader. It delivers on the 40mb per second specification and I have never had any problems with pictures getting corrupted. I ordered a second card earlier this year.

I have dropped this card in the snow, taken pictures for several hours in -15 degree weather, had it in very hot and humid conditions and never had a problem. When shooting RAW I can fill up both cards quite quickly, and when I get back home I really enjoy downloading with this setup, when I have to use other cards or readers I can see how spoiled I have become.

When I switched to Vista x64 I thought I had a problem with the reader, but I called the special tech support number for Extreme products and got to a knowledgeable and understandable tech. He walked me through the troubleshooting and now everything works great.

I do use other cards, but when I am going into unusual conditions, or know I am going to be shooting a lot, I always put this card in the camera.
