The Gold Series is backward compatible with CFexpress 2.0 hosts, allowing the card to work with compatible previous-generation CFexpress Type B cameras and devices. Transfer speeds will be limited by the older host interface, but this compatibility gives photographers and filmmakers a practical migration path toward CFexpress 4.0 equipment.
240GB, 512GB, 1TB and 2TB Capacity Options
The Gold Series is available in 240GB, 512GB, 1TB, and 2TB capacities, allowing users to match storage to their workflow. Smaller capacities can suit shorter sessions or workflows where cards are rotated frequently, while the 1TB and 2TB options provide considerably more space for high-resolution RAW photographs, long recording sessions, and data-intensive video productions. This flexibility also allows professionals to balance capacity, performance, and project requirements.
Professional-Camera-Optimized Controllers
ProGrade Digital uses controllers optimized for professional-grade cameras, emphasizing real camera workloads rather than focusing solely on headline benchmark speeds. This is particularly important in professional environments where consistent interaction between the camera and storage media can matter just as much as maximum transfer performance.
Metal Enclosure for Improved Thermal Management
High-speed storage can generate considerable heat during prolonged recording and file-transfer operations. The Gold Series uses a metal enclosure that provides effective thermal conductivity and helps manage the heat generated during intensive operation. The construction also contributes to the card's physical durability, making it better suited to repeated professional use in cameras, readers, production kits, and travel environments.
Built-In Thermal Throttling Protection
The card incorporates thermal throttling to protect itself and stored data when operating temperatures become excessive. Rather than allowing uncontrolled heat buildup during demanding workloads, the card can manage its performance as thermal conditions require. This provides another layer of protection for professional workflows involving sustained recording or prolonged high-speed transfers.
Refresh Pro Support for Card Health Monitoring
The Gold Series is Refresh Pro enabled, providing access to ProGrade Digital's card-maintenance ecosystem when used with the separately available software and compatible hardware. Refresh Pro can be used to monitor card health and refresh card performance, giving professionals another way to maintain their media between shoots and identify potential issues before an important production.
LDPC Error Correction for Data Integrity
An integrated LDPC (Low-Density Parity-Check) error-correction engine helps detect and correct data errors within the flash-storage system. For photographers and filmmakers handling valuable footage and irreplaceable images, robust error correction is an important part of maintaining reliable data storage throughout the card's operating life.
SMART Support for Storage Health Information
The card supports SMART functionality, adding storage-health monitoring capabilities to its professional feature set. When paired with compatible tools, SMART information can provide insight into the condition of the storage device, supporting more proactive media management instead of relying solely on visible performance problems to indicate that a card may require attention.
Sanitize Support for Storage Management
Alongside SMART functionality, the Gold Series includes Sanitize support as part of its NVMe-based feature set. This gives compatible professional storage-management environments access to standardized media-management functionality and further distinguishes the card from storage products focused solely on basic read-and-write operation.
Advanced NVMe Power Management
The card supports NVMe power states PS0, PS1, PS2, PS3, and PS4, allowing power consumption to adapt according to operating requirements. This is valuable in battery-powered cameras, where every component contributes to overall power consumption. Efficient power-state management helps the storage system reduce unnecessary energy use when maximum performance is not required.
Less Than 2 mW PS4 Power Consumption
In its PS4 low-power state, the Gold Series consumes less than 2 mW. This extremely low standby power requirement is particularly useful in mobile camera workflows, helping minimize unnecessary power consumption while the card is not actively handling intensive read or write operations.
Built for Demanding Environmental Conditions
Professional shoots do not always happen in climate-controlled studios. The technical datasheet specifies an operating-temperature range of -10°C to 70°C and a storage-temperature range of -20°C to 85°C. This broad environmental tolerance makes the card suitable for a wide range of field-production conditions, although users should always keep equipment within the specified operating limits.
Up to 95% Non-Condensing Humidity Tolerance
The Gold Series is specified for operating and storage humidity of up to 95% non-condensing. This gives photographers and production crews additional flexibility when working in humid environments while emphasizing the importance of preventing condensation from forming directly on electronic equipment.
50G Shock Resistance
The card is engineered to withstand 50G shock for an 11 ms duration, adding physical resilience for demanding mobile workflows. Memory cards are frequently inserted, removed, transported, packed into cases, and used across multiple cameras and readers, so resistance to physical shock provides an important durability advantage for professionals working away from controlled environments.
Vibration Resistance for Mobile Production
ProGrade specifies vibration tolerance of 1.52 mm displacement from 10–200 Hz and 15G acceleration from 10–2,000 Hz. This added resistance is beneficial for professionals who transport their equipment frequently or work in environments where cameras and storage equipment can be exposed to ongoing vibration.
X-Ray Proof Construction for Travel
The Gold Series is specified as X-ray proof, an especially useful feature for photographers, filmmakers, journalists, and production teams who regularly travel with their media. It provides additional reassurance when memory cards accompany camera equipment through common X-ray screening environments.
Designed for Operation at Extreme Altitudes
The card carries an altitude specification of up to 24,384 meters at 2.26 psi, extending its environmental durability credentials beyond ordinary shooting environments. While most users will never approach these limits, the specification demonstrates the card's engineering for professional applications across a wide variety of atmospheric conditions.
Compact CFexpress Type B Form Factor
Despite its high performance, the card maintains the standard CFexpress Type B dimensions of 29.6 × 38.5 × 3.8 mm. This compact form factor allows professional cameras to access PCIe-based storage performance without requiring physically large removable media, making it well suited to modern mirrorless, cinema, and other compatible professional camera systems.
Rigorous Full-Card Testing
ProGrade Digital subjects its professional cards to full-card testing as part of its quality-control process. For professionals whose work may depend on a single recording medium during a critical shoot, manufacturing validation is an important benefit that goes beyond raw transfer-speed specifications.
Component-Level Quality Testing
Quality control extends beyond testing the completed card. ProGrade specifies component-level testing down to individual memory chips, providing another layer of manufacturing oversight. This approach is intended to identify component issues before the finished storage product reaches a professional workflow.
Serialized Component and Manufacturing Tracking
ProGrade uses serialized tracking of key components and manufacturing information, providing greater traceability throughout production. This type of quality-control infrastructure is particularly relevant to professional storage, where consistency and accountability are important alongside performance.
High-Speed Camera-to-Computer Workflow
The Gold Series is not only designed to capture data quickly; it is also built to accelerate what happens after shooting. When paired with an appropriate CFexpress 4.0 reader and high-speed computer interface, read speeds reaching 3,400 MB/s can significantly reduce the time required to ingest large photo and video projects. Faster offloading means professionals can move from capture to backup, editing, grading, and delivery more efficiently.
Future-Ready Performance Without Sacrificing Compatibility
Combining CFexpress 4.0 performance with CFexpress 2.0 backward compatibility gives the Gold Series a strong long-term advantage. Users can purchase the card for compatible equipment they already own and retain it as they transition toward newer CFexpress 4.0 cameras, readers, and workstations capable of exploiting its higher bandwidth.

Lucas worked with me diligently to help me find a camera that would fit my needs and that would arrive in time for my trip. I take photos, but wanted a smaller, more compact camera to take with me when traveling. He even reached out to other camera experts to make sure he was giving me the best advice for the equipment that would accommodate my needs!
Lucas was patient with me and was in constant contact with the camera supplier to keep me updated on the status of my order and when the items would be ready for shipment. Once my order arrived to the store, it was in my hands in less than 2 days. I would give 10 stars to this business if I could!!
SHOP SMALL! :)
AMAZING SERVICE!
In short: I was able to receive the black colorway below retail and free next day shipping with the promos that they offered for being a new camera web-shop based from AZ.
Long story: Lucas who is prolly the only rep for the company cuz they're so small is the best dude ever. Since i ordered he responded on emails and updates quicker than some of my friends texting me back about where am at on the list as people just kept cancelling their order. I went from 9th place in line to 4th place in line for the silver. And he hit me up saying that they were still waiting on Fuji to send shipping updates and that no company knows what they get on their weekly fuji shipments other than from a 24 hour window of receiving shipping details.
He then noted that there were two black X100Vs available that were reserved to customers who ordered but have not confirmed. I said if they dont confirm please let me know and ill take that instead of the silver. The next day he hits me saying the customer said to cancel and he sent me an invoice. I ordered accessories for the camera on amazon right after and my package for the camera came before my amazon package. Lucas was super nice and transparent about everything. Dope experience from NUZIRA.
Lucas was so incredibly helpful!!! I’ve genuinely never had better customer service. They offered to stay late so I could get my order and were so patient with all my questions. I would give them 10 stars if I could.

NUZIRA MADE MY MONTH!
I was a little concerned when I first came across this small business but I am so so thankful I di! They have the NICESt staff and customer service. I have been on the waitlist for this camera for a few months now so when Lucas called saying they had it back in stock I was so freaking excited! Made my whole month. This camera absolutely lives up to the hype. I love how lightweight it is. I can pop it into any bag and head out the door. the images are crisp, high quality, and stunning. I use film sim and not film sim. The film simulations are nearly identical to real film. I have another fuji camera that does film sim but it can't even be compared to this one. I love my Fujifilm X100v so much! Amazing camera! Thanks you Nuzira!
