Cons

The ProGrade Digital CFExpress Cobalt each recorded high-resolution video in a warmth advisory and survived a couple of hours in a freezer unscathed. The built-in thermal throttling helps the cardboard attain larger speeds than competing choices. Each recording and importing to a pc are fast.

Actually, the one draw back to the ProGrade model is the associated fee. It sits considerably larger than competing playing cards from SanDisk. Nevertheless, it’s not an apples-to-apples comparability — this card is out there in capacities for 165 GB, 325 GB, and 650 GB whereas competing playing cards have 128, 256, and 516 GB capacities.

I’m giving the ProGrade CFExpress Cobalt 5 out of 5 stars and the Editor’s Selection Award.

Add speeds are going to fluctuate primarily based on the reader used — I used the ProGrade Digital reader. The reader has a CFExpress in addition to an SD card slot with a USB-C connection. It makes use of a magnet on the underside. That’s nice if in case you have a metallic desk or a metallic submitting cupboard close by. However, make sure that to maintain that magnet away out of your laptop display screen.

Construct High quality

I recorded a one-hour, twenty-minute 5.7K video throughout a warmth advisory with temperatures within the 90s. I additionally shot images inside a blacksmith store, which shortly turn into a very popular room with 4 forges working. In each situations, the cardboard had zero points. The digital camera stored taking pictures with out missed burst photographs and I didn’t discover any dropped frames on the video. I additionally didn’t get any overheating warnings.

To see how the cardboard handles temperatures to the other excessive, I dropped it inside an ice dice tray and put it in my freezer for 3 hours. After the ice dice melted off of it, the cardboard nonetheless held all the information inside intact. Be aware that as a result of ProGrade doesn’t promote waterproofing, I stored the highest of the cardboard the place the electronics are out of the water.

The ProGrade Digital CFExpress Cobalt can deal with excessive temperatures.

Efficiency

Utilizing this card, the Panasonic GH6 was in a position to shoot on the full marketed velocity, together with a 5.7K video and 75 fps bursts. I may watch the video on the again of the digital camera nearly instantly. The 75 fps has a lag, nevertheless it was considerably lower than recording with a UHS-II SD card. Extra usable bursts that gained’t refill a tough drive in 5 minutes, like 15 fps, had just about no lag time.

Uploads have been so quick that I regarded away from my laptop display screen for a break up second and Seize One was already doing accomplished importing. This was with about 140 images and a handful of brief video clips. I used to be fearful that there could be a velocity loss from my built-in SD card reader to an exterior USB-C. However that doesn’t appear to be the case right here. Uploads felt even sooner than an SD card, by no means thoughts the dongle. Be aware that totally different dongles might have an effect on velocity — so one other reader might not be fairly as quick as ProGrade’s.

I’ve gotten bizarre errors with dongles earlier than. For instance, my XQD card reader disables the web on my laptop computer when it’s plugged in. I didn’t expertise any of those points utilizing the ProGrade reader.

Who Ought to Purchase It?

The ProGrade Digital CFExpress Cobalt is a wonderful possibility for photographers and videographers that must file massive information shortly — and in excessive temperatures. It’s quick, sturdy, and unbothered by sitting in a freezer or taking pictures 5.7K within the 90s.

The playing cards are priced accordingly, nonetheless, and those who don’t want that quick velocity or excessive temperature sturdiness can discover different CFExpress playing cards at a bit friendlier value level.
