Engineered for creators who demand consistent performance in real-world conditions, the 256GB Capture+ CFexpress 4.0 Type B Memory Card from Glyph Technologies supports uninterrupted recording for professional photo and video workflows. This card offers a storage capacity of 256GB and offers read speeds of up to 3700 MB/s, write speeds of up to 850 MB/s, and sustained write speeds of 550 MB/s, making it suitable for 12K+ raw video, raw image sequences, and rapid fire shutter bursts. Furthermore, SteadyIO allows transfer speeds to remain stable across large, sustained workloads, without throttling or thermal slowdowns.
Built to support the CFexpress 4.0 standard via the PCIe 4.0 x2 bus, this card is backward compatible with CFexpress 2.0 and 1.0 devices. To help ensure a long operational life, an advanced thermal design offers stable performance during extended recording sessions, while there are also safeguards that save buffer files and shut down the card in the event of camera power loss or sudden ejection from a card reader. Also featured is resistance to temperatures ranging from 10 to 162°F, moisture, dust, shock, X-rays, and magnets.
