Other World Computing (OWC) has released the Atlas Core CFexpress 4.0 Type B 256 GB card, now in general availability. The drive promises up to 3571 MB/s read and 2227 MB/s write, topping the VPG200 benchmark and positioning itself as a fast yet affordable option for pros and enthusiasts. It targets workflows that demand rapid off‑loading and uninterrupted capture.

The card slots into Canon R-series, Fujifilm GFX, Nikon Z and Panasonic S‑series bodies, and Nikon DSLRs such as the D5, D500 and D850 that use XQD. OWC bundles Innergize software for health checks, firmware updates and restoration, while a warranty backs resistance to impact, shock, UV and x‑rays. With sustained 368 MB/s writes, the card easily records 8K compressed streams. Retail price stands at $279.99.

By delivering professional‑grade speed without the premium price tag, the Atlas Core challenges the market dominance of higher‑cost CFexpress cards and gives wedding, documentary and indie filmmakers a reliable fallback for RAW bursts and 4K/8K compressed footage. OWC’s emphasis on durability and free management tools makes the card a practical choice for anyone who can’t afford missed frames today.
