Sony photographers and videographers have a selection in the case of reminiscence playing cards: persist with widespread and low cost SD playing cards or step as much as the considerably sooner, albeit pricier, CFexpress Kind A format. Pergear has been making Kind A extra accessible for a short time now, and their newest Grasp CFexpress 4.0 Kind A card goals to push efficiency boundaries additional, at an awesome worth. Does it ship?
The brand new Grasp line makes use of the CFexpress 4.0 normal. This considerably boosts potential speeds over the older CFexpress 2.0 by adopting PCIe 4.0 expertise, which gives as much as 2 GB/s per lane. This improve guarantees the next efficiency ceiling, and I have been testing the brand new Pergear Grasp card to see if it delivers on its guarantees of enhanced velocity for inventive workflows.
For context, CFexpress Kind A slots are a staple for a lot of trendy Sony cameras, together with the a7R V, a7S III, a1, a9 III, and FX cinema line cameras. They provide a considerable bump in learn and write efficiency over the quickest UHS-II SD playing cards. This interprets to sooner buffer clearing throughout high-speed burst capturing, considerably faster ingest instances for giant picture and video recordsdata, and entry to larger bitrate video recording modes on appropriate cameras.
It’s vital to notice that every one these cameras can’t make use of the additional velocity supplied by 4.0 in comparison with 2.0 playing cards. For readers and ingest operations, you may see the velocity distinction, but when your digital camera has a 2.0 slot, it may’t write at 4.0 speeds.
Specs
Pergear’s new Grasp line comes with the next figures and options:
Learn Speeds: marketed as much as 1,780 MB/s
Write Speeds: marketed as much as 1,600 MB/s
Sustained Write Velocity: 700 MB/s
VPG Ranking: VPG200 licensed
Capacities: 256 GB, 512 GB, and 1 TB
Video Functionality: 4K60P, 8K30P, and 4K120P uncooked video storage
Guarantee: 5-year long-term guarantee
These marketed speeds, significantly the learn and peak write figures, symbolize a big leap from their earlier technology playing cards. The VPG200 certification is a welcome addition, guaranteeing a minimal sustained write velocity of 200 MB/s, which is essential for dependable video recording.
Efficiency
After I obtained the brand new Pergear Grasp card, I used to be desirous to see the way it carried out in real-world and artificial benchmark eventualities. My earlier expertise with Pergear’s older Kind A card confirmed it to be a strong worth. The important thing query was whether or not this new Grasp line really delivered a big velocity enhance.
In my testing, utilizing artificial benchmarks, the Pergear Grasp card confirmed a dramatic enchancment in learn speeds. I persistently measured learn speeds exceeding 1,400 MB/s. It is a main uplift. For offloading giant batches of uncooked recordsdata or high-resolution video clips, this implies import instances may be considerably lowered.
When it got here to put in writing efficiency, my assessments at a queue depth of 1 yielded leads to the 450 MB/s to 500 MB/s vary. These figures fall in need of Pergear’s marketed 1,600 MB/s peak write speeds and the 700 MB/s sustained write velocity, however are nonetheless good. Importantly, the cardboard carries a VPG200 score, guaranteeing a minimal sustained write of 200 MB/s. My testing confirmed write efficiency exceeds this VPG200 baseline, making it succesful for essentially the most demanding video codecs on present Sony cameras.
General, the brand new card delivers considerably larger learn speeds in comparison with older technology playing cards, in addition to now carrying a assured minimal write velocity by way of VPG certification, however confusingly steps again in write speeds in artificial masses.
Worth
Pergear has positioned its reminiscence playing cards as value-focused options that also provide high-level efficiency, and the Grasp sequence continues that development. At $129 for 256GB, Pergear is positioned a bit higher than competing playing cards from OWC or ProGrade for related rated specs.

At $129 for 256 GB, Pergear is positioned a bit higher than competing playing cards from OWC or ProGrade for related rated specs at MSRP.
The financial savings introduced by Pergear rises with capability, with the 512 GB and 1 TB fashions providing even greater advantages. Nonetheless, I did see higher efficiency out of those competing playing cards on the write velocity assessments. Whereas no digital camera to my data can at present hit these write speeds on Kind A playing cards, with my testing counting on artificial masses, it’s nonetheless one thing to contemplate for future our bodies or purposes.
A powerful level within the Grasp card’s favor is the included 5-year guarantee, a beneficiant guarantee interval for a reminiscence card. The addition of VPG200 certification additionally provides to its worth proposition, assuring a baseline degree of video efficiency and making certain higher compatibility with cameras.
Nonetheless, be sure that to examine pricing, as rebates or gross sales on playing cards, significantly on the decrease capacities, can drastically shift the value per GB, which makes a giant distinction within the worth of the cardboard relative to opponents.
The Pergear Grasp CFexpress Kind A card is a step ahead in learn efficiency, however write efficiency is a blended bag. The near-doubling of learn speeds in comparison with some older playing cards is a big real-world profit for anybody regularly transferring giant recordsdata. In the meantime, the examined write speeds did not attain the bold advertising claims utilizing artificial masses. Nonetheless, the cardboard now carries VPG200 certification, marking an enchancment in efficiency and compatibility with steady write speeds, significantly for video purposes.
If Pergear maintains aggressive pricing, they may provide a compelling bundle for Sony shooters trying to capitalize on the velocity of CFexpress 4.0 for faster imports. The spectacular learn speeds, dependable video recording efficiency backed by VPG200, and a 5-year guarantee make it a robust contender.
What I Favored
Considerably sooner learn speeds in comparison with earlier technology playing cards (measured over 1,400 MB/s)
Makes use of the newer CFexpress 4.0 normal with PCIe 4.0 help
VPG200 certification ensures a minimal sustained write velocity of 200 MB/s
Dependable for high-bitrate video recording and demanding codecs
Aggressive pricing, particularly at larger capacities
Robust worth in comparison with opponents like OWC and ProGrade
5-year guarantee provides long-term reliability
Quicker file ingest instances profit workflows with giant picture and video recordsdata
Backward-compatible with CFexpress 2.0 digital camera slots (at lowered velocity)
What I Did not Like
Actual-world write speeds fall in need of the marketed 1,600 MB/s peak
Artificial benchmark write outcomes (450–500 MB/s) are decrease than anticipated
Present Sony cameras can not make the most of the total velocity of CFexpress 4.0
Competing playing cards might provide higher write efficiency
