And people said CF Express type A cards would not get cheaper...

[AlphaWorld]

I was curious to see the local price of the Sony CF express type A v4 480GB card. Found a local dealer who has a price up. To my amusement, the local price is the same as the nominal RRP of the 160GB v2 card that was the first CF type A card Sony offered. I bought my first one of those in January 2021, in anticipation of the arrival of the A1. Back then people ranted about the price...

Now, in less that 5 years, you can get a CFeA card with 3x the capacity for nominally the same price (considering inflation, it's cheaper). That card isn't just 3x the size, though. It's also over 2x the speed (1800MB/s vs 800MB/s).

I think these cards are still not “mainstream” like SD cards and still in the high end imaging niche. As such the price remains ridiculously high. I just did my first shoot yesterday with an a1ii using my SD cards (slot 1 RAW slot 2 JPEG) and had no buffer problems even with tracking a player at 30fps. That said, I don’t shoot video so maybe an issue there with high res stuff, but for my work I am going to stay with fast SD cards until I see some better prices. I guess sometime in the future SD cards will go the way of 8 Track tapes (you young folks may need to Google that and why a pack of matches was key to getting the tape to line up correctly in the tape deck).

Is there any reliability improvements for CF over SD? Outside of cameras I have never seen CF Express used. HP server I am picking up this week still has onboard microSD slot. My Raspberry Pi 5 still has SD slot, but I do have added NVME card. But no CF Express options anywhere I have seen. Osmo Action, GoPro, Insta360, and the rest all still use SD. Like Chris3754 said, they just are not mainstream and pricing reflects that....and it sucks.

At least the AngelBird CF v2 cards are good price. $130 for 160GB card. Sony's Tough brand 128GB SD card sells for $139.

Great question on reliability, hopefully someone can jump in here on that subject. Although I have never had an SD card issue, I have heard that complaint. Of course I am heading to shoot another ice hockey game today and have probably jinxed myself.

I have now had 3 cf card failures. The problem here is, what was at fault? The card, the reader, the laptop or the camera?

Could be any/all of those.

One bad habit I used to have is to simply pull the card out of the reader on my PC. I've read that Win11 (sorry, don't know how this translates on a Mac) sometimes had delays in flushing the cache for the card - potentially leading to issues with the card when files are not properly closed. I now force myself to choose the 'eject' option from the taskbar and wait for the buffers to flush...

As always, YMMV.
