Introduction<\/span><\/h2>\n

Pergear entered the memory card market later than many of the bigger players, but in 2022 and 2023 they launched high-spec CFexpress Type B and Type A cards at far more budget-friendly prices. They\u2019re quickly carving out a place for themselves alongside more established brands.<\/p>\n

When they asked if I wanted to test their newest card, I agreed\u2014mainly because I wanted to see how it stacks up against the cards I already use in my cameras. Let\u2019s take a closer look.<\/p>\n

Pergear kindly provided the memory cards and card reader for test and review purposes.<\/p>\n

Why Memory Cards Matter<\/h2>\n

One of the most important parts of a modern camera is the memory card. We buy them out of necessity\u2014mainly as a way to record our pictures and footage in the field, then transfer them safely to our hard drives back home or in the office.<\/p>\n

Like with a mule, what matters is how much load it can carry and how quickly it can transport that load\u2014including loading and unloading. And just as it\u2019s important that a mule doesn\u2019t damage the cargo during the journey, it\u2019s equally crucial that a memory card doesn\u2019t corrupt our data.<\/p>\n

Because of that, we often spend quite a bit on them, and the price usually comes down to three key factors: capacity, speed, and reliability.<\/p>\n

In this review, I\u2019ll look at how the card compares with my other current cards and how it measures up against the company\u2019s own specifications.<\/p>\n

Reliability is trickier to judge, since that really shows itself only after years of use.<\/p>\n

With that in mind, let\u2019s see how the card performs in practice.<\/p>\n

Contenders and Tests Setup<\/span><\/h2>\n

I tested all cards in my Nikon Z7II, when applicable. The Pergear and Lexar CFE cards were tested in the Pergear’s 2-in-1 USB4.0 reader connected to a USB 4.0 port. All the SD cards were tested in my laptop’s internal SD Express 7.0 card reader.<\/p>\n

Tests<\/span><\/h2>\n

This section details the technical methodology and results of the performance tests. Readers who are primarily interested in the final assessment may proceed directly to the conclusion.<\/p>\n

A comparison of the listed specifications in the previous section reveals that the Sony XQD card, despite being the oldest and slowest non-SD card in this group, has a higher theoretical speed than even the fastest SD card. Additionally, the Pergear card’s theoretical speed is more than double that of the fastest non-SD card. Now, we will test the performance of these cards.<\/p>\n

Synthetic Benchmark<\/h3>\n

For the initial benchmark, I used CrystalDiskMark with the Flash Memory preset. The tests were run in three rounds, using block sizes of 128 MiB, 1 GiB, and 8 GiB. After repeating the full test multiple times, I selected the complete result set that recorded the highest overall write speed for this analysis. The results are as follows:<\/p>\n
