Digital Camera World Verdict

Delkin Device’s Black CFexpress Type B cards are a bit more expensive than some of the competition, but the promise of a replacement within 48 hours without the company actually needing have received your faulty card is reassuring. You need to pick the right capacity to get the performance you want, but the 128GB cards are the fastest that the company has to offer.

Delkin Devices has been pretty serious about memory cards for a few years now and in addition to a lifetime warranty, it offers a 48-hour replacement guarantee. This means that the company will replace any non-working (registered) card within 48 hours or less (not including weekends). You can also replace your card over the counter at any authorized Delkin reseller.

There are two lines in Delkin Devices CFexpress card range, the Power cards which are designed for use in high-end cinema cameras for 6K and 4K raw video recording, and the Black cards that are designed to support 8K raw video recording. I’m looking at the 512GB Black card in this review.
