ProGrade Digital unveils 512GB Cobalt UHS-II SDXC card

May 3, 2022

ProGrade Digital has announced its 512GB Cobalt UHS-II SDXC memory card, which is said to deliver maximum read and write speeds up to 300MB/s and 250MB/s respectively.

This new 512GB card offers V90 performance, which guarantees that its minimum write speeds for video never drop below 90MB/s.

ProGrade’s new 512GB V90 SDXC memory card is only the third ever to offer V90 write speeds in combination with 512GB storage.

The only previous memory card makers to do so were Wise and Sabrent when the world’s first-ever 512GB V90 SDXC UHS-II cards arrived, in March 2022.

The Wise 512GB V90 SDXC UHS-II was launched in late March 2022

The importance of VPG-90

The VPG-90 speed rating equates to a sustained write speed of 90MB/s, which is the highest sustained speed rating for the SDXC memory card format.

Memory cards used for video have different speed ratings to the traditional maximum write speeds for stills.

For shooting video, you need to know the minimum sustained speed when you’re recording high bit-rate video directly to the card.

This is because video is written to the memory card in real-time and doesn’t wait for the card to catch up

The 512GB Cobalt SD card is said to be both X-ray and shockproof, and is claimed to be capable of operating between -25ºC (-14ºF) and 85ºC (185ºF).

It also features built-in error correction that detects and corrects data write and data transfer errors.

Compatible with Refresh Pro

Wes Brewer, founder and CEO of ProGrade Digital, commented, ‘Today’s creative pioneers are producing more video than ever before. With the extensive range of recording options in today’s high-end professional camera market, such as RAW 8K, 6K, 5K, 4K, UHD, High Bit Rate MPEG at varying frames per second, many of which require high capacity, and high-performance memory cards. We have added this higher capacity 512GB, SD V90 memory card to our SDXC Cobalt product line to serve these needs. This card will also be compatible with our unique Refresh Pro software, allowing professionals to refresh their ProGrade Digital cards back to factory condition and monitor the health of their cards.’

ProGrade’s Refresh Pro software allows users to ‘sanitise’ and restore their cards back to factory condition after use.

ProGrade Digital already produced SDXC V90 cards in 64GB, 128GB and 256GB capacities
