  • Memory Cards — Consumer & Industrial

What is the difference between consumer-grade and industrial-grade memory cards?

A: Consumer-grade memory cards (e.g., standard SD/MicroSD) use TLC or QLC NAND flash and are optimized for high capacity and low cost for everyday use. Industrial-grade memory cards use SLC or MLC NAND, support wide operating temperatures (-40°C to 85°C), offer significantly higher endurance (P/E cycles), built-in ECC error correction, power-loss protection, and a guaranteed long product lifecycle — making them ideal for 24/7 mission-critical applications.

What memory card form factors and capacities does Digilux offer?

A: Digilux offers three product lines — Premium, Turbo Speed, and High Endurance — in both Micro SD and SD formats, with capacities ranging from 4GB to 1TB. Speed grades include Class 10, UHS-I (U1/U3), UHS-II, and video classes V30/V60/V90. Custom specifications are available upon request.

What applications are High Endurance memory cards designed for?

A: High Endurance memory cards are engineered for applications with continuous, heavy write cycles, such as dash cameras, CCTV surveillance systems, drones, and outdoor trail cameras. Compared to standard cards, they offer a substantially higher TBW (Total Bytes Written) rating, preventing premature wear from prolonged video recording.

What are the differences between SLC, MLC, TLC, and QLC NAND flash?

A: SLC (Single-Level Cell) stores 1 bit per cell, delivering the highest endurance (up to 100,000 P/E cycles) and fastest performance — ideal for industrial and mission-critical use. MLC (2 bits/cell) offers a balance of endurance (~10,000 cycles) and cost, suitable for industrial transitional solutions. TLC (3 bits/cell) is cost-effective for consumer products. QLC (4 bits/cell) provides maximum density at the lowest cost but with the lowest endurance, best for high-capacity, low-write-frequency scenarios.

What operating temperature range do Digilux industrial memory cards support?

A: Digilux industrial memory cards support a wide operating temperature range of -40°C to 85°C, making them suitable for outdoor equipment, in-vehicle systems, factory automation, and medical devices operating in extreme thermal environments.
