# What this deal is
Delkin Devices is offering its 150GB BLACK CFexpress Type B memory card for $136.99 USD, a discount reported as $100 off the usual price. The card targets professional shooters who need high sustained write throughput for raw images, continuous burst stills, and high-resolution video recording.
# Core technical facts
- Capacity: 150GB.
- Bus/interface: PCIe 3.0 (CFexpress Type B form factor).
- Max read speed: up to 1725 MB/s.
- Minimum write speed: at least 1530 MB/s (stated minimum).
Those numbers indicate strong sustained write capability compared with many SD formats, and the card is positioned to handle high bitrates and frame rates for 4K, 6K, and 8K video capture as well as rapid RAW stills capture.
# Ruggeding and reliability features
Delkin's BLACK Series cards are described as waterproof and shockproof, and tolerant of temperature extremes. Each card is serialized for tracking, and the product comes with a limited lifetime warranty plus a 48-hour replacement guarantee if you register the card with Delkin.
# Who should consider this card
- Photographers shooting RAW in continuous burst mode who need fast sustained writes to avoid buffer stalls.
- Videographers and cinematographers recording high-bitrate 4K, 6K or 8K footage where sustained write performance matters.
- Field shooters who require a rugged card that tolerates water, shock and temperature variation and want a serialized card with quick replacement support.
# Practical buying considerations
- Interface: The card uses PCIe 3.0. If you require PCIe 4.0 speeds for future-proofing or extremely high sustained writes, compare to CFexpress 4.0 Type B offerings before purchasing.
# How this compares in market context
This card sits with other pro-tier CFexpress offerings that prioritize sustained write speeds and durability. It trades off cutting-edge peak speed (PCIe 4.0 cards reach higher read/write ceiling numbers) for a balance of high sustained write speed and a lower price point when on sale.
# Bottom line
If you need a rugged CFexpress Type B card with strong sustained write performance for RAW stills and high-resolution video, the Delkin 150GB BLACK at $136.99 (reported $100 off) is a cost-effective option. Confirm that 150GB meets your recording needs and that your camera supports CFexpress Type B before buying.
