I was able to use it only twice and then afterwards, my macbook can no longer detect it.[...] I am simply disappointed in this product. I should have checked out ALLl the reviews about it including blogs abour how it did not work with other users, too..

BOUGHT THIS FOR THE NEW SPEED AND IT HAS PROVEN TO BE FAST AND RELIABLE.

Used to capture high school sports

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

well, worth the little extra $ to have the faster read/write speed

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

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.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

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!

FAST AND RELIABLE WITH MY CANON 5D MARK II

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

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.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

keeps up great with my canon 50d works very fast and the write time is very quick

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

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).

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

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.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

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!

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Great CF Card. Super fast read and write. What more do you need. Perfect for D300 and newer fast cameras.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Extremely fast, UDMA capable, capacity is perfect to transfer to DVD disk to store each session.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash 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.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

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!!!!!!!!!!

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Is faster than the cards that i have use before

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

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

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I prefer this size card because it is the closest match to a DVD disc for saving my photos.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Fast in the camera, faster downloading to the computer. I love the fact that I've never had any trouble at all with SanDisk Ultra II, Extreme III, and Extreme IV cards and have extra confidence knowing that if I did, SanDisk backs me 100%. The supplied recovery software is 1st rate and can be a real lifesaver. For these reasons, SanDisk is the only card I'll use.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I FIND THE SAND DISK EXTREME MEMORY CARDS ARE IDEAL FOR MY USE. WHEN PHOTOGRAPHING ON LONG HIKES. ITS SPEED ENABLES ME TO FIRE RAPIDLY WHEN ACTION SHOTS ARE REQUIRED. MEMORY SIZE PROVIDES LONG RECORDS WHEN DOING INTERVAL TIMING .

Extremely fast card. Strong construction. Excellent warranty.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I have 2 grandchildren and love to take pictures of them....They play sports and swim and the card seems to work really fast. I have only had this card for 2 weeks and don't find anything I don't like about it...I thought I needed a special reader but it works fine in the reader I have on my computer.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

My D300 loves it.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I will only depend on two brands for my professional work...which is shooting all day long, always super sweaty, hot temperatures, and I can't afford to lose images or else I'll lose clients.

Great product.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Great speeds-works excellent with D300 and rapid shooting.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Great card fast reliable no doubt top of the line.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

With Digital Cameras having larger files you need larger cards for Storage. The 4g gives you more room but is still not too big (I personally don't like putting all my images on one card). Perfect size. I also have a very comfortable feeling with SanDisk. Like them and their product.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Essential piece, no problems at all.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

would buy again

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

When I began using my Canon 1DS Mark III, the first thing I noticed was how long it took for the image to show up on the LCD after I shot it. A few milli-seconds with a faster card does make a difference. After success with the Sandisk Extreme III and my former cameras, I decided to buy the extra speed of the Sandisk Extreme IV. I now get almost immediate write and display, though it still lags a bit when a number of images have been buffered.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I only use this for my camera. So far it's had no issues. It's relatively fast and had no read or write errors. Although I find that extremely rare overall.
Shooting 8mp raw gives me a little over 400 pictures.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I have used Sandisk cards exclusivly on all my digital cameras for more then eight years and have never had any problems.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I used this card for a couple thousand shots taken while on an Southern African Safari and Great White Shark Diving trip and had no problems. It performed flawlessly during hot and dry conditions as well as many days in rainy and ultra humid conditions. Happy with the purchase and would recommend this card to anyone who needs a decent amount of speedy storage to shoot with.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

With my Nikon D200, my 2Gig cards just didn't hack it... Especially storing in RAW&Find JPeg. I was changing cards just too frequently. Having two 4Gig cards allows me to continue shooting with one, while my other 4Gig is being downloaded to my external storage.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Very good for the fast life.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Great performance as expected from Sandisk, no complaints whatsoever. I have two and will probably buy a third here soon!

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Fast and reliable storage. A great item for the Nikon D300. Useful ability to retrieve deleted files.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

The CF is excellent as it is the Extreme III. I haven't notice the difference between both, except in the price.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I own two these cards and have not had any problems with them and definitely would buy more in the future.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Best Card I ever worked with...get one.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

When you buy top of the line you get top of the line....Period

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Some memory cards seem to be trouble waiting to happen. This one seems to be rock solid.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I have used San Disk CF cards for the past three years and find them consistantly reliable and fast. These cards even resist extreme temperature
and saturation with ice water. While other CF cards like eFilm have failed, Extreme IV has
always performed outstandingly.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Really like this Compact Fash Card. It has great capacity and it's fast.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Helped to not have to "pop in so many cards" after going raw...

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I'm a hold out from the film side and have only been into digital for about a year. I currently have various digital cameras with the Nikon 200 as my main one. The card has performed well but I do not see that much difference between this and the III. Again, I do not shoot everyday although I do shoot at extreme speeds at time for dog agility shows and fast moving wildlife. Overall, I believe anyone who purchases the card will be very satisfied.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I really needed this for its speed and storage of my pics. In today's digital world this card gives me 240 pics shooting at RAW with my Nikon D200.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

The extreme IV is very fast. When I need to shoot in continous mode it keeps up.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Extremely fast in my Nikon D2Xs both in writing and downloading.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I have a one gig scandisk and a 2 gig scandisk have never had a problem even with the recovery disk they give you for the ones that you delete and need to retreive. Software is the so easy to use.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

flawless. and the peace of mind is worth the price.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I have not had any problems with my Nikon D200 writing to this card. It works wonderful when shooting Jpegs, but I need a 8gb or larger for shooting RAWs....

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

very reliable, fast to read and write. i had extreme III's and was very happy, but then i tried this card and was even happier. if you can get it at a good price w/ rebate then there is no better.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

i Had extreme III's and have no complaints. but then i bought 2 fo these extreme IV and with the rebate going on its money well spent. they are fast! sandisk are very reliable. its the only brand i trust! you wont be dissapointed.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

The card is excellent, and does it's job extremely fast, and performs perfectly. However, upon originally inserting the card into my Nikon D200, it refused to format. I've never had this problem before. I finally contacted SanDisk, and while they were giving me some work-around ideas, it did format properly. That was after at least a dozen prior attempts. It has worked flawlessly since.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Can't really tell the difference between the III and IV with the Nikon D200.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Lost one at a scenic overlook and didn't come back to find it til 23 hours later. Tire tracks in the gravel/sand indicated that it had been driven over. After dusting it off, I stuck it in my camera and started shooting. It's still going strong 15,000+ shots later!
The Extreme series (III and IV) are very fast cards, but more importantly, they're totally dependable. I've taken over 50k shots with III and IV series cards and have never lost a single image. You can get cards that are (maybe) faster from no-name companies - at a risk. I've read too many boo-hoo stories about those who did and the card died at the worst moment to risk it. Go ahead, shell out the extra 15% and buy the VERY BEST CF card currently on the market!

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I've been using SanDisk CF cards (mainly 2GB extreme III) for a couple years with never a problem. With my purchase of the Canon 5D (12.9 mp) and shooting exclusively Raw, I needed a bigger card. The 4gb extreme VI is perfect...plenty fast and never a problem with capture or uploading to my computer.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

I really haven't had the time or opportunity to fully utilize this amazing card.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Its fast!!!

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Took multiple photos in raw plus jpeg fine at 10 megapixels. Card writes and downloads with the Extreme IV reader really quickly. Would certainly recommend!

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Sandisk cards have always lived up to my expectations.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Bought this 4GB card for a recent trip to India and Sri Lanka to avoid having to change cards at a critical moment and to have the speed and the reliability I associate with SanDisk. Although it is a bit pricey, my time and the pictures I take are too valuable to risk using bargain basement cards. I even had the opportunity to use the recovery software which comes with it when an assistant accidentally erased pictures on a 1GB SanDisk. The recovery software works flawlessly. Hallelujah!

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

Outstanding product, does everything expected.

Comments about SanDisk SanDisk 4 GB Extreme IV Compact Flash Memory Card.:

amazing the speed of this card, I wonder how I ever took photo's before this card. last time I was this amazed was when I first used a microwave oven....
