WD Purple SC QD101 Surveillance MicroSD Card 256GB

Product Overview

The WD Purple SC QD101 256GB MicroSDXC Surveillance Card (WDD256G1P0C) is an ultra-endurance edge storage solution purpose-built for 24/7 continuous video surveillance, high-resolution edge recording, and extended standalone multi-week footage retention, this card delivers consistent write persistence to eliminate dropped frames in professional 2K, 3K, and 4K Ultra HD IP security cameras, CCTV systems, smart video doorbells, and mobile terminals.

Fabricated with advanced 96-layer 3D NAND flash technology, the QD101 series meets Speed Class 10, UHS Speed Class 3 (U3), and Video Speed Class 30 (V30) standards, sustaining continuous high-bitrate video streams (H.265 / H.264) during primary edge recording or automatic network failover. Equipped with proactive Card Health Monitoring firmware integration, compatible cameras can read remaining endurance in real time to prevent unexpected storage failure. Delivering a high-endurance rating of up to 128 TBW (Terabytes Written) and tested across extreme temperatures from -25°C to +85°C, it is ideal for commercial perimeters, enterprise campuses, and residential security installations.

✅ Key Features

• Capacity: 256 GB — MicroSDXC (SDA 6.0) format.

• Speed Performance: Speed Class 10, UHS Speed Class 3 (U3), Video Speed Class 30 (V30) — sequential read speeds up to 100 MB/s, sequential write speeds up to 60 MB/s.

• Surveillance-Grade Endurance: Up to 128 TBW (Terabytes Written) optimized for continuous 24/7 rewrite cycles.

• 4K UHD & High-Resolution Capture: Sustained throughput optimized for multi-megapixel streams and smart video codecs (H.265+ / H.264+).

• Card Health Monitoring: Real-time health diagnostic reporting through supported IP camera firmware.

• Loop Recording Compatible: Seamlessly auto-overwrites the oldest video footage when capacity is reached.

• Extreme Durability: Waterproof, humidity-resistant, shock/vibration-proof, and airport X-ray safe.

• Wide Operating Temperature Range: Operates reliably in harsh exterior climates from -25°C to +85°C.

📸 Compatible Devices

• Professional IP Security Cameras (Bullet, Turret, Dome, PTZ)

• Video Intercoms, SIP Video Door Phones, and Access Control Terminals

• Smart Video Doorbells and Battery/Solar-Powered Perimeter Cameras

• Fleet Dashcams and Mobile Surveillance Recorders (MDVR)

• Standalone edge-recording devices with MicroSDXC slots

🕐 Approximate Recording Capacity at 256GB

• 720p @ 15fps: ~40–56 days of continuous recording

• 1080p @ 15fps: ~28–36 days of continuous recording

• 1080p @ 25fps: ~16–24 days of continuous recording

• 2K / 4MP @ 15fps: ~12–20 days of continuous recording

• 4K UHD @ 15fps: ~7–10 days of continuous recording

• Motion Detection Mode: Up to 2–4× longer retention compared to continuous streams

Note: Actual recording days depend heavily on video compression standards (H.264 / H.265 / Smart Codecs), individual camera bitrates, framerates, audio recording channels, scene complexity, and motion detection configurations. Enabling motion-only recording substantially extends local video retention.
