TF
256GB TF CardProvides generous storage for 4K videos, large game files, extensive photo libraries, and multiple apps. Great for heavy media users.
The 256GB TF Card is designed for high-capacity data storage and stable performance across a wide range of digital devices, including smartphones, tablets, action cameras, dash cams, drones, gaming consoles, and surveillance systems. With fast read and write speeds, it supports smooth Full HD and 4K video recording, rapid file transfer, and reliable app performance.
Manufactured with high-quality flash memory and advanced controller technology, this micro TF card offers excellent durability, data stability, and long service life. It is resistant to water, shock, temperature, and X-ray exposure, making it suitable for demanding environments and continuous-use applications.
Professional & Semi-Professional DronesThis is the flagship use case for our 256GB TF card. At 190 MB/s read and 130 MB/s sustained write, our card exceeds the write bandwidth requirements of 4K/60fps drone cameras operating at 100 Mbps bitrate. 256GB provides approximately 30–60 minutes of 4K footage per flight — sufficient for professional aerial cinematography, mapping, and inspection missions without mid-deployment card changes. Compatible with DJI-ecosystem and white-label drone platforms from major Chinese and Asian OEMs.
Mirrorless Cameras, DSLRs & Action CamerasProfessional photographers shooting RAW burst sequences generate 25–50MB per frame at speeds of 10–20 fps. Our 256GB TF card at V30 / 130 MB/s write sustains this workload without buffer stalls that cause missed shots. For video-focused users shooting 4K/60fps with GoPro-class or independent-brand action cameras, 256GB provides full-day coverage across multiple scene changes without offloading footage.
Professional 2K/4K IP Surveillance SystemsUnlike the 24/7 loop-record scenario best served by 512GB High Endurance cards, 256GB is optimal for standalone IP cameras and small NVR systems requiring 7–10 days of local 1080p backup storage at standard CCTV bitrates. It is also the standard capacity for AI-inference edge cameras that store event-triggered 4K clips alongside running inference model caches — where A2 random I/O performance directly impacts clip retrieval speed.
Gaming Consoles & Handheld Gaming DevicesNintendo Switch-compatible (exFAT, SDXC). Modern AAA game titles average 15–30GB per title, meaning 256GB accommodates 8–15 large games plus save data and DLC on a single card — the right capacity for bundling with gaming handhelds or gaming accessory OEM programs targeting serious gamers.
Android Flagship Smartphones & TabletsA2-rated random I/O (4,000 read IOPS / 2,000 write IOPS) makes our 256GB TF card the specification tier expected for flagship Android expandable storage applications. App cold launch times are measurably faster from A2 cards versus A1 alternatives — a tangible quality differentiator for smartphone OEMs pre-installing expandable storage in premium device tiers.
Professional Embedded Systems & Edge AIFor Raspberry Pi 5, NVIDIA Jetson Nano, and Rockchip-based edge AI platforms running large inference models and continuous sensor logging, 256GB provides meaningful model storage capacity alongside operational data. The 190 MB/s read speed accelerates model loading at cold boot — critical for deployments where startup time affects system availability metrics.
Designed for 2K/4K surveillance, drones and car video recorders, delivering high-speed performance for large-capacity video storage.

Q: What is the difference between your 256GB TF card and your 128GB TF card — when should I specify 256GB?
A:The functional differences are: (1) Capacity — 256GB stores twice as much data, enabling longer single-session recording without card changes. (2) Speed — our 256GB TF card is rated at up to 190 MB/s read and 130 MB/s write vs. up to 100 MB/s read and 40 MB/s write on the 128GB variant. (3) App performance — 256GB ships with A2 rating (4,000/2,000 IOPS) vs. A1 (1,500/500 IOPS) on our 128GB. Choose 256GB when your application involves 4K professional-grade recording, burst RAW photography, premium Android device expandable storage, or gaming console integration where A2 performance is expected.

Q: Does the 256GB TF card support 4K/60fps video recording without dropped frames?
A:Yes, provided your camera's internal write path can sustain ≥100 Mbps. Our V30/U3 write rating guarantees ≥30 MB/s sustained write, and our production-validated sustained write speed of 130 MB/s exceeds the write requirement of all commercially available consumer and prosumer 4K/60fps camera formats. For cinema-grade RAW codecs at ≥200 Mbps, please confirm your device's supported card speed class against our specification before ordering in volume.
Q: What is the actual usable capacity of the 256GB TF card?
A:Operating systems report capacity in binary units (1GB = 1,073,741,824 bytes) while card manufacturers specify in decimal units (1GB = 1,000,000,000 bytes). A 256GB card will display as approximately 220–235GB on your device. This is a universal industry standard consistent across all memory card brands at this capacity, and is not a product defect.
Q: What protection ratings does the 256GB TF card carry?
A:Our 256GB TF card is verified against five protection standards: waterproof (1-metre water immersion resistance), shockproof (1,500G mechanical shock), anti-magnetic (safe against standard magnetic fields), anti-X-ray (safe for airport security scanning without data loss), and anti-static (ESD discharge protection per JEDEC standard). These ratings make it suitable for harsh-environment deployment in outdoor cameras, vehicle-mounted equipment, and field-use portable devices.
