Delkin Devices 150GB BLACK CFexpress Type B Memory Card

💾 Delkin Devices BLACK 150GB CFexpress Type B Memory Card — DCFXBBLK150

The Delkin Devices BLACK 150GB CFexpress Type B card is engineered for professional photographers and filmmakers who prioritize sustained recording performance, reliability and responsive in-camera operation.

Using a PCI Express 3.0 interface, it delivers read speeds up to 1725 MB/s and write speeds up to 1530 MB/s. Unlike cards that advertise a high peak speed but slow considerably during extended use, this BLACK G3 card is designed to sustain write performance up to 1530 MB/s—ideal for high-resolution RAW bursts and demanding 8K, 6K and 4K recording modes in compatible cameras.

Each card is individually serialized and protected by Delkin’s limited lifetime warranty and premium 48-hour replacement guarantee following registration.

⚡ Exceptional Sustained Performance

The DCFXBBLK150 is designed around consistent performance rather than only a short maximum-speed test.

Its rated speeds include:

• Maximum read speed: Up to 1725 MB/s

• Maximum write speed: Up to 1530 MB/s

• Sustained write speed: Up to 1530 MB/s

Strong sustained writing is especially valuable during long video takes and extended continuous bursts, when slower cards may reduce performance after their temporary cache is exhausted.

Actual speed depends on the camera, card reader, computer and recording conditions.

🎬 Professional High-Resolution Video

The card’s sustained write performance supports data-intensive recording formats in compatible cameras, including:

• 8K RAW video

• 6K RAW video

• High-bitrate 4K

• High-frame-rate recording

• All-Intra formats

• Professional cinema codecs

• Extended continuous takes

• Real-time broadcast workflows

Because recording requirements differ between camera models and modes, always consult the camera manufacturer’s approved-media list before beginning a critical production.

📸 High-Speed RAW Burst Photography

Modern professional cameras can generate a tremendous amount of data during high-resolution continuous shooting. The Delkin BLACK card helps clear the camera’s buffer quickly while maintaining consistent writing throughout longer bursts.

It is particularly well suited to:

• Sports and action

• Wildlife and birds

• Motorsports

• Weddings and events

• Photojournalism

• High-resolution RAW photography

• Subjects requiring long continuous sequences

🎞️ Focused 150GB Capacity

The 150GB capacity provides an excellent balance of professional performance and manageable storage.

It is a practical choice for photographers who prefer:

• Dividing assignments among several cards

• Rotating media between sessions

• Keeping individual jobs separated

• Limiting how much work is stored on one card

• Using smaller cards for still photography

• Maintaining a dedicated card for specific cameras or recording modes

For extended 8K or RAW cinema recording, a higher-capacity card may provide longer recording times between changes.

Actual formatted capacity is lower because of system formatting and measurement conventions.

💻 Streamlined File Transfers

Read speeds up to 1725 MB/s help shorten the time required to transfer photographs and video to a computer.

Pair the card with a high-speed CFexpress Type B reader and compatible USB connection to improve backup and post-production efficiency.

Because this is a PCI Express 3.0 card, a quality USB 3.2 CFexpress Type B reader can access its available performance without requiring a newer CFexpress 4.0 reader.

🛡️ Rugged BLACK Series Construction

Delkin’s BLACK cards are designed to withstand professional use in difficult environments. The rugged construction provides resistance to:

• Water

• Shock

• Extreme temperatures

• Frequent card changes

• Demanding field conditions

Although rugged construction provides additional protection, important photographs and video should always be backed up to separate storage as soon as possible.

🔢 Individually Serialized

Every BLACK card carries a unique serial number. Serialization helps confirm that the product is an authentic Delkin BLACK card built to the specified capacity and performance standards.

It also supports inventory management and Delkin’s warranty and replacement services.

🔄 48-Hour Replacement Guarantee

Registered BLACK cards qualify for Delkin’s premium replacement program.

If a card becomes nonfunctional, Delkin can ship a replacement within 48 hours or less—excluding weekends—before receiving the defective card. Participating authorized Delkin BLACK retailers may also provide an over-the-counter replacement.

The card must be registered with Delkin to activate the replacement program and limited lifetime warranty benefits. Program terms and eligibility requirements apply.

🩺 Delkin CardDoc Compatibility

The DCFXBBLK150 is compatible with Delkin’s CardDoc software when used with a supported Delkin CFexpress reader.

CardDoc can:

• Check the card’s current health status

• Help monitor reliability over time

• Perform a complete sanitize operation

• Clear memory cells to help restore optimum performance

Delkin advises against using CardDoc with unsupported combinations of third-party cards and readers. The Sanitize process permanently erases all files and should be used only after the card has been fully backed up.

⚠️ Type B Compatibility

This card works only with cameras, recorders and readers that accept CFexpress Type B media.

It is not compatible with:

• CFexpress Type A slots

• SD card slots

• CFast 2.0 slots

• CompactFlash slots

Although CFexpress Type B has similar dimensions to XQD, an XQD camera must specifically support CFexpress Type B through its hardware and firmware.

⚖️ How It Compares

Versus the Delkin BLACK 1TB CFexpress Type B 4.0 card: The 1TB model offers far greater capacity and much faster CFexpress 4.0 transfer speeds. This 150GB G3 card provides excellent sustained performance at a smaller capacity and is ideal for photographers who rotate multiple cards.

Versus Delkin POWER cards: BLACK cards emphasize maximum sustained performance, individual serialization and Delkin’s premium replacement program. POWER cards provide a different balance of performance, capacity and cost.

Versus an SDXC card: CFexpress Type B offers substantially higher sustained performance for long RAW bursts and high-bitrate video. SDXC remains a practical option for less demanding formats and secondary recording.

Versus CFexpress Type A: Type B is physically larger and provides greater potential bandwidth. The two formats are not interchangeable.
