SD CARD DUPLICATOR – SD400PC

A Modular SD Duplication Platform Designed for Parallel Production Workflows

The SD400PC is a professional SD card duplication system built for organizations that need higher throughput while preserving flexibility in how work is structured. Delivered as two coordinated 20-target units, the system supports 40 simultaneous SD targets while allowing each unit to operate independently when needed.

The platform is built on a USB 2.0 architecture and is classified as previous-generation equipment within the Nexcopy lineup. It remains widely deployed in production environments where operational flexibility, reliability, and structured workflows are more important than maximum interface speed.

This architecture supports real-world production environments where multiple projects run concurrently, different data sets must be processed in parallel, or duplication responsibilities are distributed across teams rather than centralized into a single queue.

When the SD400PC Is the Right Choice

The SD400PC is selected when organizations need more capacity than a single 20-target system can provide but want to preserve adaptability rather than committing to a single rigid production flow.

It is commonly used in environments where two separate jobs must run at the same time, where different teams manage their own duplication queues, or where workloads need to be distributed without disrupting ongoing production.

Teams that value both throughput and operational flexibility often choose the SD400PC because it supports centralized output and decentralized operation using the same hardware investment.

Why the SD400PC Uses a PC-Based Architecture

The SD400PC uses a PC-connected workflow to provide visibility, job configuration, and validation during production. Each 20-target unit connects to a Windows workstation and is managed through Nexcopy software rather than relying on blind push-button execution.

This architecture allows operators to configure jobs precisely, monitor progress in real time, and validate outcomes through logging, verification, and reporting features that are not available on basic standalone duplicators.

Because each unit already operates within a full software environment, the platform also preserves the ability to evolve into deeper device-level workflows in the future without requiring replacement of the underlying hardware.

Production Duplication Without Altering Card Behavior

The SD400PC performs duplication at the file system and device level without modifying SD card behavior. Data is written accurately and verified, while cards remain standard, fully functional SD devices after preparation.

This model is well suited for workflows where media must remain writable, reusable, and broadly compatible after deployment while still requiring confidence that prepared cards match the intended source.

Copy Methods and Production Workflows

The SD400PC supports six copy methods, allowing teams to select the most appropriate workflow for each project rather than forcing all production into a single duplication model.

Six Copy Methods Supported

• File Copy – copy files and folders only
• Full Device Copy – bit-for-bit duplication
• Smart Device Copy – intelligent copy excluding empty sectors
• IMG Copy – write from pre-built image file
• Copy Add – append files to existing content
• Unique Data Streaming – individualized data per device

Unique Data Streaming for Individualized SD Content

Unique Data Streaming allows different data to be written to each SD card during a single job. This is commonly used for serial numbers, license files, certificates, identifiers, configuration files, or device-specific assets.

The feature supports parallel production workflows where individualized content must be generated and applied across multiple jobs without introducing manual handling for each device.

SD Data Extraction to Host Storage

The SD400PC also supports read-back workflows, allowing data to be extracted from connected SD cards and saved to host storage. This is useful for inspection, validation, collection, and archival scenarios.

Extracted data can be consolidated into a single destination or automatically organized by source device, with optional post-processing actions such as secure erase or formatting available to support controlled media reuse.
