Perfect timing! Hopefully Pergear sees this video and sees that you sold me on it. I had it in my cart but wasn’t sure if I would commit but bought it after hearing your experience. It’s exactly what I wanted to know - long term heavy use. Not use it for one shoot and call it perfect like almost every TH-camr does. Thank you!
No, I beat this thing with months of use and used it heavy as a hard drive as well. Buying unknown brands… I’m with you. It would have stayed in my cart. But for me, this thing worked well and I’ll be using it a lot for both camera and external hard drive.
I bought it one month ago, and yesterday, my card suddenly stopped working. I lost all my footage (very important footage). So, my advice is to invest in good memory cards and not take risks.
I've yet to try an CFE card in my Sony A7RV because they are too bloody expensive, I'm interested to know if these CFE cards heat up or get hot if your transfferring an entire full card from the card reader to your PC/Laptop. with the SD cards my lexar cards get red-hot and I worry about card failure due to heat damage while transffering at high speeds. Wondering if CFE cards have same heat issues.
with all due respect.... " the speeds are great on it....." No, they're not. they only write at 400 MBs max. It says so on the front of the card. Lexar, Sony, Angelbird and Prograde CFE type A write at 700 or above. I doubt if the Pergear could keep up with a 30fps continuous burst on an a1. Maybe you could test that. Regards Braden
This comment made me curious so I did some math: The Sony a1 buffer when shooting in simultaneous raw (lossless compressed, which is required for anything above 20fps) and jpg (I believe extra fine L) is 83 frames. Moving over to uncompressed raws + jpgs adjusts the buffer down to 78 frames. I forget the exact numbers, but for the sake of the math let’s say that each compressed raw photo is about 50MB and each uncompressed is 100MB, and each JPG extra fine L is 30MB. As established by previous comments, the cards write at *AT LEAST* 400MB/s (megabytes, not megabits). While we know it goes higher, I’ll use this measure for the sake of the math here. 30fps with compressed RAW and JPG extra file L results in 2.25 GB/s (2250 MB/s). Each second the card is writing at 400 MB/s, so that means the data moved to the buffer is 1.85 GB/s Blah blah blah math on assuming buffer size etc. etc.: You’d fill the buffer in roughly 5 seconds, producing 150 compressed RAW files and 150 JPGS Take a second to pause and count to five out loud. Not many situations where I’d imagine 30fps would be needed for that long. I generally shoot between 15-20 FPS uncompressed on my a1, and I rarely encountered buffer issues even prior to moving up to CF-Express A cards. TLDR; Even if 400MB/s was the max write speed, these cards would likely be perfectly sufficient. Hope this helps! Happy shooting 📸📸
I feel bad for new memory card brands, I will never buy memory from a brand that has not existed for at least 10-20 years and have a large body of work so you can compare durability and longevity of their products.

Yep no issues for me, been using them in my a7iv for months now, great cards.
Thank you for the review.
How was the turnaround from placing your order to your order being shipped?
My Sony Tough 80 serves me so well.
I got mine in July 2024, it does get hot and worked fine until today. Corrupted and in the process of recovering
Oh damn that’s not good. So 2 1/2 months in and it failed.

Going on 8 months with no issues on dual cards. Really sorry to hear you had an issue
I have a pergear lens. It's nice for the price.

All cards get a bit warm but this hasn’t got hot on me.

400 MB/s is the MINIMUM write speed, not max. The max is 900 MB/s, just fyi
Sony’s minimum is 200 MB’s, so this is technically faster.

They generally all come from the same small number of factories anyways
Did you test only one card from that company?
Yes.
