High Endurance microSDXC 256GB

The Team Group THUSDX256GIV3002 is a 256GB microSDXC card built for continuous monitoring workloads. It carries UHS-I, U3 and V30 ratings with read speeds up to 100MB/s and write speeds up to 50MB/s. The card is engineered for stable, long-term recording in demanding environments.

Upgrade from standard microSD cards

Standard cards can wear out quickly under constant write cycles from security cameras or dash cams. This High Endurance model delivers up to 40,000 hours of recording life and resists shock, water, static and X-rays. The jump is worth it when reliability over months of non-stop footage matters more than peak transfer speed.

Ideal for surveillance and dash cams

Installers and homeowners running 4K or Full HD monitoring systems gain consistent frame capture across extreme temperatures. Users needing maximum read throughput for burst photography or large file offloads should look at cards with higher speed-class ratings instead.

Questions about this item

Does this microSDXC card need a specific slot type or adapter to fit a standard SD device?

It uses the microSDXC form factor and requires a microSD slot; a microSD-to-SD adapter is needed for full-size SD slots.

What is the correct way to insert the card, and what common mistake should be avoided?

Insert the card with the gold contacts facing down until it clicks; forcing it in upside down can damage the contacts or the slot.

How many recording hours is the 256GB model rated for, and does it have a finite write lifespan?

The 256GB model is rated for 40,000 hours of recording; like all flash memory, it has a finite write endurance but is built for long-term monitoring use.
