NX-A1SE Series

• Best-in-class read up to 950 MB/s[1], write up to 950 MB/s[1]
• High-capacity lineup for long time video recording
• VPG200 compatible

In the photographic and imaging industry, where camera performance continues to evolve and image quality and resolution continue to increase, we are launching the CFexpress Type A memory cards to meet the needs for recording video and still images at the highest image quality.

Expands its product portfolio for professional imaging with the addition of CFexpress Type A memory cards to its existing SD memory card and CFexpress Type B memory card products. We are expanding our product lineup for consumers to meet the photographic needs of more customers.

The NX-A1PRO series is a CFexpress Type A memory card for professional users who handle high-speed continuous shooting and high bit-rate video.

Best-in-class write/read speeds.

The maximum transfer rate of 950 MB/s for both write and read, the highest level in its class, and the minimum continuous write speed of 850 MB/s are achieved. [1] [3] The number of consecutive shots possible during high-speed continuous shooting has been increased, and the buffer memory release time has been shortened. This reduces the number of missed shots at the desired moment.

Dynamic Auto Power Save, a unique low-power consumption technology that stabilizes video recording.

Nextorage's unique power saving technology, "Dynamic Auto Power Save," reduces power consumption by up to 88% compared to the case without.[1]

In addition to reducing power consumption during video recording, thermal throttling* is also suppressed by reducing the temperature rise of the card itself. (*Thermal throttling: a control function that attenuates the transfer rate to prevent thermal runaway)

This enables stable video recording.

It also reduces the camera's battery consumption, which contributes to extending the available shooting time.[1]

VPG400 compliant, as required for professional video shooting.

All capacities comply with the Video Performance Guarantee VPG400 (minimum guaranteed continuous write speed: 400 MB/s). It has the specifications required for professional video recording.

Abundant lineup of capacities for various applications

80 GB/160 GB capacity lineup for high-speed continuous shooting of still images and VPG200 for video shooting requiring.

High capacity 320 GB/640 GB available.

The CFexpress Type A is now available to professional users who have not yet used the CFexpress Type A. We want our customers to experience the performance of our 40GB capacity at an affordable price.

The NX-A1SE series is a CFexpress Type A memory card for video creators who shoot long, high-quality videos.

Best-in-class write/read speeds.

Achieves a class-leading maximum write/read transfer rate of 950 MB/s. [1] Reduces data transfer time after shooting.

High-capacity lineup for long-time video recording

The high-capacity lineup of 480 GB,960 GB and 1,920 GB supports long-time movie recording, and is ideal for switching from SD cards, as it dramatically improves shooting time and data transfer speeds compared to SDXC UHS-II memory cards.

From Nextorage:

Nextorage Announces the release of the NX-B2PRO series, the world's fastest [1] CFexpress™ 4.0 Type B memory card, and the NX-SB1PRO, a 40Gbps card reader that supports CFexpress 4.0

(Nextorage Corporation; President: Katsuyuki Honda; Kawasaki City, Kanagawa Prefecture, Japan) Nextorage will begin selling the NX-B2PRO series of CFexpress Type B memory cards compatible with CFexpress 4.0 on February 20, 2024. The NX-SB1PRO CFexpress 4.0-compatible card reader is scheduled to be available during March 2024. The memory card and card reader are compliant with CFexpress 4.0, the latest standard set by the CompactFlash Association (CFA), dramatically reducing the transfer time of high-capacity data captured when shooting 8K video and high-resolution still images.

NX-B2PRO Series

• CFexpress Type B memory card compatible with CFexpress 4.0
• World's fastest [1] transfer rate in terms of maximum read speed (3,900MB/s [2 ]), maximum write speed (3,600MB/s), and minimum continuous write speed (3,400MB/s [3] )
• Unique power-saving technology, Dynamic Auto Power Save, reduces the camera's battery consumption during video recording. It also suppresses card temperature rise and maintains stable write speed.
• CompactFlash 400, a standard defined by the CompactFlash Association's Video Performance Guarantee (VPG), guarantees a minimum write speed of 400 MB/s when used with a host device that also supports VPG400.

The NX-B2PRO series is a next-generation memory card that is expected to be supported by the high-end camera market in the future. (*CFexpress 2.0 standard is used for transfer in devices that do not support CFexpress 4.0.) It is backward compatible with the existing CFexpress 2.0 standard for current cameras, allowing stable, high-quality video recording and high-speed continuous shooting on par with the NX-B1PRO series.

The camera's unique low power consumption technology, Dynamic Auto Power Save, reduces power consumption during movie recording. This reduces the camera's battery consumption. In addition, the card's temperature rises at higher transfer speeds, preventing thermal throttling* from occurring. Another feature of the NX-B2PRO is its ability to maintain stable transfer rates. This fast and stable read/write performance supports 8K video and high-speed continuous shooting in RAW quality.

Since the camera supports VPG400, users can shoot 8K video with confidence when using it with the Canon EOS R3/EOS R5/EOS R5C, which support VPG400. With a broad lineup of capacities ranging from 165 GB, 330 GB, 660 GB, and 1330 GB, users can select the card that best suits their shooting needs, from high-quality still images to high-speed continuous shooting, 8K video, and more. CFexpress Type B memory cards provide stable recording in a variety of shooting scenes and reduce data transfer time after shooting.

Durability [4].

Durable and compliant with CompactFlash Association regulations and backed by a 5-year product warranty.

• Heat resistance: -12 °C to 72 °C (guaranteed operating temperature)
• Shock resistance (EIA-364-27A compliant)
• X-ray resistant (ISO7816-1 compliant)
• UV resistant (ISO7816-1 compliant)
• Magnetic resistance (based on Nextorage's own testing)

Product Compatibility

Nextorage is currently verifying the compatibility of the NX-B2PRO series with CFexpress Type B memory card compatible devices from various companies. Information on devices whose compatibility has been verified is scheduled to be updated on the Nextorage website as needed.

NX-SB1PRO

• CFexpress Type B Card Reader for CFexpress 4.0
• USB 40Gbps interface (maximum transfer rate: 5,000 MB/s)
• Extracts the transfer performance of CFexpress 4.0 cards (maximum transfer rate specification value: 4,000 MB/s)
• Stable high-speed transfer performance due to the unique heat sink structure with high heat dissipation performance

With USB 40Gbps (maximum transfer rate: 5,000 MB/s), this card reader maximizes the high-speed transfer performance of CFexpress Type B memory cards compatible with CFexpress 4.0 (maximum transfer rate standard value: 4,000 MB/s). In the NX-B2PRO330G (maximum read speed: 3,900 MB/s [2] ), which is available today, a data read speed of 3,300 MB/s is achieved. [1]

In addition, a large heat sink with a proprietary structure has been developed to counter the rise in temperature of the card body and card reader that accompanies the increase in transfer speed of various standards, such as CFexpress 4.0 and USB 40Gbps. This suppresses the occurrence of thermal throttling* and realizes stable data transfer at high speeds.

This card reader for CFexpress Type B supports the latest high-speed standards and reduces workflow time after shooting.

Product Compatibility

Nextorage is currently verifying the compatibility of the NX-SB1PRO with CFexpress Type B card reader compatible devices such as PCs from various companies. Information on devices that have been verified for compatibility is scheduled to be updated on the Nextorage website as needed.
