This is a great little card. But there are a couple of things to keep in mind before picking it up.

1) Don't expect the 300x to make a big difference while you are out shooting, especially if you are using a modern digital SLR. Cameras seldom take full advantage of flash card speed, largely because they don't have to thanks to their big, fast internal buffers. 99.9% of the time I could get by with a glacially slow card because my DSLR can buffer 40 RAW frames before it even needs to write to the card.

2) The 300x will make a big difference when transferring files from the card to your computer, but only if paired with a UDMA card reader. On paper this card boasts 300x speed, or 45 MB/s. That seems stellar, but when I plugged it into my trusty USB 2.0 CF card readers, I found the actual transfer speed to be 4 MB/s for both reads and writes! (Yes, 4 MB/s -- that's not a typo. And yes, I'm sure it's a USB 2.0 reader using a USB 2.0 port. I even repeated the exercise with another reader from a different vendor to verify my results.) I tested by moving several GB of 15MB RAW files, as well as some 1GB video clips to measure sustained performance. Obviously the problem was that my reader could not take advantage of the full UDMA speed of this card. Fortunately I had a third UDMA USB 2.0 reader, and keeping all other variables constant, using that reader my write speed jumped to 14 MB/s and reads went to 33 MB/s, or about 220x, which is quite respectable and hugely better than the 27x speeds I was enduring before.

Make sure your reader supports UDMA and you'll be very happy with this card.

Not much to say other than FAST!!!! 300X equates to 45 megabytes per second transfer speed! That's FAST!!!!

This card is being used in my Sony A-700 camera body. Taking pictures on full auto mode does not overrun the card. I could fill the entire card with one shutter button press if I wanted to.

The card will hold 408 pictures in full, uncompressed RAW mode (with a Sony A-700 12.24 megapixel camera). That's equal to over 11 rolls of 36 exposure 35mm film! In JPEG or other compressed modes, this card holds THOUSANDS of images!

A few things to watch out for (these are generic warnings - not specific to the Lexar UDMA card):

* Be sure your CAMERA can SUPPORT an 8GB card before you buy.
* Be sure your CAMERA can SUPPORT an UDMA card before you buy.
* Be sure your COMPUTER card reader is USB 2.0 or FireWire, full speed and can support UDMA.

That's all. You need a wicked fast memory card for your camera or other data storage use? ... The 8GB Lexar UDMA 300X CF Card will make you very happy!

i went looking for a more reliable and larger card than the 133x 4gb sony card i purchased when i bought my 40d, having had a lexar pro 2 gb card and knowing their proven reliablity i went with this card, and man, i couldnt have made a better choice. i shot a whole wedding with this card and never missed a beat. the card was as fast as the camera. even at $169, you cant find a better card. Bravo Lexar!!

I shoot a Canon 5D and work with dancers in performance. The shooting is quick, often strings of many frames with the camera running as fast as it will cycle. When I changed from 133x cards to 300x cards, I noticed a significant improvement in the speed with which the camera's buffer clears, allowing longer strings and better readiness for more shooting. This is only going to be more important with newer cameras having higher resolution and faster cyclic rates. This Lexar and the Sandisk Extreme Ducati series claim the 45MB/sec performance level. I use both with equal satisfaction. I have recently switched from 4GB to 8GB cards to reduce the number of reloads necessary during a job.

bought this for use on my D300 and they are a deadly quick combo.
it will save over 1K images shooting on the large/fine JPEG setting and a little over 300 images on RAW.

Lexar Professional UDMA - Flash memory card - 8 GB - 300x - CompactFlash
I use a a Canon 5D and love Lexar cards. From the first digital camera I had many years ago, I always got better response from the Lexar one as compared with other brands. First it was 4X, then, 8X then 16X, then 40X, then 80X, then 133X, now 300X. My cameras went from 3.3 MP then several 8 MP, now 12.8 MP so there was a need for faster and larger cards. Well Lexar has kept up. I now have 5 of the 8GB 300X. I still use the 8 GB 133X as well as some 40 and 80X cards. The difference I notice is down loading my images to my computer, the 300X is way faster with a proper card reader. Even with the express card reader on my laptop in the field the 300X card downloads the 8 GB faster. Also when shooting a burst of pictures, whether its getting the right image at sporting events or a bird in flight, with either my Canon 20D or now the Canon 5D, I never have to wait for the files to write to the cards.

I like the peace of mind that comes from the quality of Lexar products. I spend a lot of time, effort, and money getting the images and the thought of loosing them due to card problems is unimaginable. I also no doubt will be getting the Canon 1DS Mark IIII in the near future, and like the idea than the cards I am now using will be fast enough to keep up with the 21 MP camera. So no regrets.

Well off to Alaska with my Lexar cards,

Cards...I haven't mastered a clear understanding of memory cards. I want speed, reliability, and capacity. Lexar is a one of two brands that I place my trust in....no doubt.

I am personally very satisfied with the performance of this product. Is very fast memory and I use it with my Nikon D3

UDMA cards are expensive compared to the next level down -- Lexar Professional and SanDisk Extreme III. The extra cost may be justified for newer cameras with high write speed capabilities and 12+ megapixels, and a UDMA card like the Lexar 300X downloads to your computer perceptibly faster. This CF card definitely delivers on the promise of higher speed, so if that's what you want it's worth the price.

Fast fast, and faster. I never run out even shooting raw.
High buffer. 6 frames per second, no waiting, etc....
Highly recommend. Not cheap.
