ProGrade 250MB/s UHS-II V90 64GB SDXC Card Review

ProGrade 250MB/s UHS-II V90 64GB SDXC Memory Card

Introduction

ProGrade Digital was founded in early 2018 by former Lexar executives to deliver high quality memory cards and workflow devices. They formed the company after Micron, Inc. sold the Lexar brand. ProGrade is targeting upmarket consumers and professionals who need reliable, high-performance storage for digital SLR and mirror photography and video recording.

Their initial ProGrade offering includes UHS-II Secure Digital and Cfast memory cards. ProGrade UHS-II SD cards are available in two varieties: 200MB/s and 250MB/s. This review will focus on the high-performance 250MB/s card with Video Speed Class 90 (V90) rating. The V90 rating provides enough speed for high quality video recording up to 90MB/s continuously. There are three capacities available: 64, 128 and 256 GB. The 64GB SDXC card (PGSD128GBCJBH) with UPC 853229008339 is tested in this review.
