Capacity and purpose

This 256 GB microSD card includes an SD adapter for use in smartphones, tablets and cameras. It is rated Class 10 with UHS-I U3 performance for 4K UHD and Super Slow Motion recording. The card targets users who need reliable portable storage for high-resolution media. It is not suited for buyers who want more storage than 256 GB.

Thermals, noise and power

Solid-state memory has no moving parts, so the card runs silently and produces negligible heat during normal read and write operations. Power draw is minimal and supplied entirely by the host device. No active cooling or external power is required.

Build quality and daily use

The card offers 6-way protection: waterproof, temperature-resistant, X-ray-proof, magnet-resistant, drop-proof and wear-free. The bundled SD adapter lets the microSD card fit full-size SD slots without extra accessories. Rated read and write speeds reach 160 MB/s.

Questions about this item

How do I insert the microSD card and SD adapter without damaging the contacts?

Hold the card by its edges, align the gold contacts with the slot, and push gently until it clicks; forcing it at an angle bends the contact pins and voids the 6-way protection.

What maintenance or replacement will this 256 GB card need after heavy 4K UHD recording?

The card is wear-free and has no moving parts, so no scheduled maintenance is required; replace it only if capacity fills or physical damage occurs.

At what point does sustained write speed become the limiting factor during long 4K UHD sessions?

The 160 MB/s write speed is the ceiling; once the buffer fills, the card cannot accept data faster than that rate.
