SANDISK 256GB Extreme PRO CompactFlash Memory Card, UDMA 7 | Read Speeds Up to 160MB/s, Shot Speeds Up to 150MB/s, 4K UHD - SDCFXPS-256G-X46

SHORT VERSION: For those who do not want to read the entire review, let me break it down. These are incredible, and worth every penny. I have used them professionally for a few years, and they have never let me down. If you are looking for a incredible CF card, you have found it. LONG VERSION: To start, let met start off by saying that I am a professional wedding photographer. We photograph roughly between 25-35 weddings a year. We currently have 5 Canon cameras, and 6 of these Sandisk Extreme Pro 128gb Compact Flash cards. The ages range from about 3 years old, to 3 months old. This year alone, we will have taken roughly 4 Terabytes of raw photos. 100% of our photos will have gone through these Extreme Pro cards. Out of the entire time I have owned these cards, they have never let me down. I have never had a failure, never had a corruption. Our cameras are set up with two memory card slots. Most are 1 CF and 1 SD. We also use Sandisk Extreme Pro SD 128gb cards. Our cameras are set to write RAW to both. These cards are the fastest CF that Sandisk offers. The speed not only helps when writing to the card itself (Most cameras max out at about 50-60MBs) but when you are downloading them back to your computer. Thats where they really shine. Use a Lexar HR1 4 bay hub. We have 4 cards downloading at once, and the fast 160MBs speed helps with time. I have attached a screen shot of a speed test performed one of these cards. It was performed by a USB 3 Lexar CFR1 reader. The speeds are lower than what is rated, but that could be my USB3 reader, and not the actual card. When shopping for memory cards, there are several brands. But I 100% believe that Sandisk are the best. We use Sandisk exclusively in every camera we own. I was not reimbursed in any way for this review. Pros: Extremely reliable Relatively inexpensive for the size Fastest Speeds that Sandisk Offers Cons: Not the cheapest on the market. TIPS TO GET THE MOST OUT OF IT: For proper data management, you should ALWAYS format (not delete) your card inside the camera. Every single time. For proper workflow, it should be downloaded to a computer, put back in the camera, and then formatted. That will ensure that your data is as safe as possible. That has been my workflow, and I have never had a corruption issue.

This works really well in my Nikon D700. The camera is able to write fast in burst mode. I LOVE the high capacity.

Sandisk is always a great card. Fast speed. Easy to format and work with my camera.

Bought this yesterday in preparation for a family vacation to replace my old 2GB card that takes FOREVER to transfer pictures. Snapped a dozen or so pictures around the house to put some images on the card, the camera recognized it immediately and worked flawlessly with it. The transfer speed from card to PC via USB-C is good, not blazing fast but certainly not slow by any means. This will allow me to takes lots of pictures on vacation and transfer them to my NAS to create a slideshow for our echo show in no time. Very happy with it after just a few hours. I'll update this review of I have anything to add, but for now, this is a fantastic card for the price, 32GB holds a ton of pictures with room to spare! Highly recommend this for anyone with an older DSLR that uses CF cards!!

Works fine with my Canon 5d mkii. Get some. Recommended.

Best there is!!!

First up IMO a five star review should only be reserved for products that EXCEED expectations. no product that does what it's supposed to do should get extreme praise. So this one does what it should, record my images as fast as my camera's cache can dump to it and gets a fair four star rating. My 120MB/s "Extreme" that I bought lagged behind my fast shutter speed and internal camera memory and dropped some images. That said, in ALL camera applications there are things to be aware of which applies to all memory cards used in a camera. 1. Format the card in the device you're going to use it in. 2. Trying to force it in upside down may crack the card or bend the pins in your camera / device. 3. USB transfer may beat card removal due to the possibility of #2 above. 4. If your camera / device has the ability to write simultaneously to TWO CF cards it's a very good idea to have two installed. A Pro simply cannot tell a client the shoot went bad because a memory card failed. Also, a memorable private event like a wedding, Bar Mitzvah, Christening, baby pix, or vacation is worth the cost of a redundant memory card and is well worth the added expense.

No complaints with this CF card. The read/write speeds are excellent. I could go larger capacity card but 32GB is perfect when it comes time to do all of my post editing. SanDisk has been my reliable tool in all of my photography or memory needs.

速度/容量とも問題なし。

Excellente carte mémoire,ça réputation n'est plus à faire.

Works great every day without fail, good value, good quality

EOS-1DX 用 録画に使用のため購入。海外リテイル品で不安でしたが試し撮りで問題なく使用出来ました。 もう一枚購入を検討中です。

サンディスクCFを、20年以上使用してきた。 容量に不足を感じたので、新しい物を探した。 容量だけでなく読み書きの速度も上がっていて、しかも価格もそこそこ。 大変満足している。 購入直後に、価格が上がっており驚いた。
