If you’ve been waiting for a 512GB V90 Class 10 SDXC memory card, you now have two options to choose from. Within the past few days, both Wise and Sabrent have released 512GB UHS-II SDXC cards, which promise a V90 Video Speed Class, ensuring the cards never write slower than 90MB/s.

The two cards are nearly identical, with only a small difference in read/write speeds. The Sabrent 512GB card maxes out at 280MB/s and 250MB/s for read and write speeds, respectively, while Wise’s 512GB card offers slightly faster read and write speeds at 290MB/s and 260MB/s, respectively. These speeds are slower than other V90 cards on the market, but the 512GB capacity is double that of V90 SDXC cards offered by the likes of ProGrade Digital and Sony.

The slightly faster Wise cards will come at a much higher cost, however. Wise’s 512GB V90 SDXC card is expected to retail for $800, while Sabrent’s offering will undercut it by $200 for just $600.

Both Wise and Sabrent say their respective 512GB V90 SDXC cards will hit shelves next month. Sabrent has opened up pre-orders for its 512GB V90 SDXC card, while Wise’s offering doesn’t appear to be live yet.
