SanDisk 128GB Extreme PRO CompactFlash Memory Card UDMA 7 Speed Up To 160MB/s- SDCFXPS-128G-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 reliableRelatively inexpensive for the sizeFastest Speeds that Sandisk OffersCons: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 card is great, it functions with a very quick storage speed which is nice when I am shooting at a fast continuous shooting speed. It still takes a few seconds pause after I shoot quickly like this, but it recovers after about 2 seconds to allow me to continue shooting afterwards.

Product quality as expected and delivered promptly

The 300 cost too much!!

I use this card with my Canon 7D Mark II - more than enough space for any trips I make where I know I'll be taking lots of pictures.

I purchased this CF Card for my Canon 5D MK IV 30 MP Camera to take advantage of the faster image transfer speed.

We bought this to go with our Nikon d810. We have loved how well it has worked.Pros:Very fast write speed.Large amount of memory.Cons:none as of yetIs my review missing something?I think that honest, well thought out reviews sometimes are forced to take the place of personal experience while online shopping. I've always appreciated the help I've received from reviews and work hard to return the favor as best as I can. I hope you found this review helpful and if there was anything you thought was lacking or unclear leave a comment and I'll do what I can to address it.

Performs as described. I got expedited international shipping and it came quicker than I had anticipated (just what I had hoped for). My product is Genuine (though I haven't registered with Sandisk yet).My only concern is the card gets hot, but, this happens with all my cards and a lot of the heat is probably from the Camera itself, so I doubt there's any issues. When reading information from the card and ingesting into my computer via USB 3.0 the card is faster than my Hard Drives, meaning the HDD is the bottleneck. This isn't the case on my SSD drives but shows the card's performance at both read and write is killer.I ordered another product with this card (not related), it was the X-Rite colorchecker MSCCC, it arrived with a white fleck on it and I am fairly disappointed. I just want to let people know, should circumstance change I will be sure to add an [EDIT] tag and a timestamp to show what the news is.
