getting harder to find

love the extreme line of memory cards from sandisk. i'm just sorry the smaller capacity, high speed cards are getting more and more difficult to find. i still find it helpful to use the 4gb cards for all day shoots and swapping them out for a fresh card for the next day.

Now even faster...

The new Extreme IV is 45 MB/S, faster than the earlier version. I own both versions of the 4GB cards. I have never had any problems.

Great Product that I would buy again

Since getting my full frame camera the files got a lot larger. This fast card downloads efficiently with the companion firewire reader. The 4GB is great as it stores easily on a DVD without having to edit the contents.

The Extreem 4 cards are great without any problems

I have used earlier versions of SanDisk cards without any complaints. The Extreem 4 cards are great without any problems. My only beef with SanDisk is the rebate policy! A rebate posted in May for a earlier purchase has not been received!

Extremely fast

This CF card will never be the bottleneck in my photography. I can push the shutter and the camera doesn't slow down or stop like my old one did.

Reliable, Easy to Use

I use this as the memory card in my Nikon D300 camera. I have chosen the 4GB size because should I lose a card or should one malfunction (which hasn't happened yet) I would not lose all my work. I have found the memory card to be reliable and fast (I shoot in RAW mode).

Do you shoot RAW...you need these!

First off with the rebate going couldn't pass it up. I have one from a few months back and clearly my most reliable card. Shooting RAW the write and read times are faster and having access to multiple cards for storage as a relief. Buy these cards...I love 'em!

Great Product

I use SanDisk exclusively when out shooting youth sporting events. I have never had a card freeze or lose my images. I made the jump to Extreme IV last year and love the fact that I can shoot in continuous mode and rarely if ever have to wait for the buffer to clear, I also love the fast download to computer. Extreme IV is faster than III. I own 32 GB of these cards in various sizes. They are awesome. Used in Nikon D300 and D70.

A very Reliable Memory Card

I use various 4GB cards. This allows me to shoot many pics of any subject or any place/event. If I start shooting at another place or subject, I only have to switch to another card. I can keep my pics more organized.

Fast

I cannot say anything negative about this card other than I wish I would have purchased it when they first came out. Great product as I have come to expect from SanDisk. My other SanDisk 4 gig card was attacked by my beagle and continues to give me great results. The only difference is this one is seriously FAST!!!!!!!!!!

Great for UDMA apable devices

Fast if you have equipment that supports UDMA and don't forget you'll need a matching card reader.
