With the release of the latest Pergear Standard CFexpress Type-A memory card, Pergear now has two series CFexpress Type-A memory cards, this latest “Standard” series and the more professional “Prime” series.
In this article, we’ll examine the Pergear Standard series 256GB card, its features, and performance benchmarks.
Pergear was kind enough to send me a sample to put it through its paces. Here is what I’ve found.
Pergear Standard 256GB CFexpress Type-A Review
The Pergear Standard CFexpress Type-A cards are currently available in two sizes: 256GB and 512GB. Their minimum write or sustained speed is rated at 380MB/s, which means these cards should technically have plenty of performance headroom for some pretty high-end video codecs and very fast buffer-clearing speeds, all at a more affordable cost compared to the Prime cards or some the other CFexpress Type-A cards on the market.
Considering their competitive price, these new Pergear Standard cards are excellent solutions for casual photographers looking for great value.

Pergear Standard 256GB CFexpress Type-A Benchmarks
I used the Lexar CFexpress Type-A + UHS-II 10Gbps memory card reader to test this memory card with the AJA System Test on Windows 11. The AJA system test is nice for testing memory cards, allowing me to benchmark cards with various codecs and file sizes.
If you want to mirror my settings, I use a 4GB Test File Size, at 5120×2700 5K Red, with a codec type of 16bit RGBA.
I also pushed about 64GB of data to the card several times to test the sustain speeds, which came in slightly below the rated spec.
Card Tested | Write Speed | Read Speed | Sustain Speeds |
Pergear Standard CFeA 256GB Rated | 780 MB/s | 780 MB/s | 380 MB/s |
Pergear Standard CFeA 256GB Tested | 768 MB/s | 806 MB/s | 253 MB/s |
Performance tests with AJA were very positive. The max write speed was 768MB/s, more than double what we could see from any UHS-II card, and this card is more than half the cost.
When looking at Crystal Disk, we hit a top write speed of 824MB/s and a top write speed of 805MB/s.
For the Crystal Disk tests, I’ve changed the settings for NVMe SSD instead of Defaults, which gives that second row a SEQ128K instead of 1M. The RND performance is tested with 16 threads instead of 1. This simulates how a computer might use it when mounted. Then, I also tested with a 2GB test at three runs instead of 5 and 1GB since many of our cameras usually use around 2GB or larger buffers.

Sustained Disk Write Captures
Using a 64GB sample size in the AJA system test, we can see the flash configuration of the Pergear Standard cards. It looks like the card uses a fast flash of around 4-6GB as the cache, and then we have a slower flash that runs at around 250MB/s.

Note: This Pergear card seems to dislike Prograde readers. There were problems with the cache resetting. I don’t know why this happens, but sometimes, the card’s cache does not reset, so it gets stuck running at the slower flash setting and not using the fast cache. Switching to the Lexar reader solved the problem.
Is There Any Competition?
The closest competitor or the next step up would be the Lexar Silver CFexpress Type-A cards. These cards are also very competitively priced but feature a much faster sustain speed and cost more money.
Bottom Line
Overall, it’s an insane value for a 256GB card that launched at around $130 for the 256GB model.
For casual photography, not doing anything crazy, these Pergear Standard cards are one of the best values out there. On this site, based on clicks, Pergear cards are some of the top sellers, and overall, Sony shooters seem to be happy with the performance.
The only issue I’ve had with Pergear cards is that the cache is not resetting, which also happens on one of my Prime cards; I’ve had this happen with some Prograde cards as well. This might be a Windows 11 drive issue.
However, even with the cache not resetting (which means they’ll get stuck running at their sustained speed), the Standard cards are still faster than any UHS-II v90 cards and come at a significantly lower price.
