Planning on an Antarctica trip next year. Will these cards work under those harsh weather extremes?
Asked by: George
I have been to Antarctica and the Artic regions during their respective summer periods. Most of the time in Antarctica, it was in the mid-thirties. In the Artic (Svalbard region) it was even warmer, low to mid forties. I over-dressed at first, but it was no worse than a Michigan winter. Camera and cards worked well for thousands of shots.

This card has higher sustained write compared to all older Black card gens. why would anyone buy older gen Black cards overthis?
Asked by: Andrew
There is no reason to buy a slower Delkin card from the Black line over the Delkin Devices 1TB POWER 4.0 CFexpress Type B Memory Card. For this reason, many of the older Delkin Black cards are being discounted and/or discontinued.

How do these differ from the Delkin Black series? Running temperature wise, sustained write speeds, etc?
Asked by: Richard
The Delkin Devices 1TB POWER 4.0 CFexpress Type B Memory Card can write at a similar max speed and runs at a similar temperature than the Delkin Devices 1.3TB BLACK 4.0 CFexpress Type B Memory Card. However, the sustained write speed of the BLACK card is higher at 2150 MB/s vs. 1570 MB/s on the POWER card.
