Great Memory Cards

By Ben
Rated 5 out of 5
Date: 2026-09-01

I ordered these memory cards because the I currently had were smaller memory wise and I am going to be going on a long vacation and I felt I needed a larger capacity memory for the trip. I previously used this brand and I have been happy with the quality and reliability of the cards. These are now the 4.0 version and so I thought this was a great time to upgrade. Happy with the cards so far and have no regrets in making this purchase. I would recommend this product to others.

Better than SD for Video and Large Pics

By Michael
Rated 5 out of 5
Date: 2026-08-28

I just recently got my first mirrorless capable of holding a CF card. Using the CF for RAW and video and using the SD for jpeg backup. A bit nervous at first because I didn't recognize this brand name. But it seemed to be well reviewed. And after a month of ownership, absolutely no issues. Actually, it did seem to get hung a bit on something coming in and out the camera at first. But fine now.

How critical is VPg ratings

How critical is VPg ratings
Asked by: Venkat
VPG ratings on CFexpress cards validate a minimum speed rating the card can achieve. Whether or not the rating is vital depends on the camera model you're using and the video recording format you're shooting in, as different cameras and formats have different minimum speeds that need to be maintained by the memory card.

I am using a Z 8 with a Delkin Black 150 CF Express Card Type B and NO backup card. How does the Delkin Power 512 compare?
Asked by: David William
I have a black 320 and 2 Power 512s and they have all been reliable so far. I can’t determine if one is faster than the other. Maybe the Powers get hot quicker but I really do not know. Living in a warm humid climate means everything heats up!
