  • MLC technology delivers 10x longer lifespan than standard cards
  • Up to 95MB/s read and 60MB/s write speeds for 4K recording

32GB Twin-Pack MLC High Endurance

This two-card set delivers 64GB total of microSDHC storage built on MLC flash rated for ten-times the write cycles of standard cards. It targets drivers and installers who need continuous Full HD recording in dash cams or security cameras, and each card includes a full-size SD adapter and a protective mini case.

Dash-cam and surveillance users.

The 32GB per card capacity suits loop recording that overwrites daily footage, and the V30/U3 rating sustains the bit-rates those devices demand. Buyers who want larger single-card capacities for extended 4K sessions or bulk media libraries should look at something else, as should anyone needing application-class random I/O performance.

V30 sustained write speed

A guaranteed minimum write of 30MB/s — marked by the Video Speed Class V30 logo — is the specification that decides whether the card can keep up with constant Full HD streams without frame drops. If the host device requires V30 or U3, this pack meets that threshold; if it demands a higher sustained tier, it does not.

Questions about this item

How do I install the Gigastone Industrial 32GB microSD card and which adapter slot do I use?

Insert the microSD card into the included SD adapter, then place the adapter into your device's full-size SD slot. Ensure the card clicks fully into the adapter before inserting to avoid read errors.

Will the MLC flash on these cards wear out and need replacement after heavy dash-cam use?

The MLC High Endurance design is rated for ten times the lifespan of standard cards, supporting six years of daily four-hour Full HD recording before replacement is typically needed.

At what sustained write speed does the card hit its limit during continuous 4K recording?

The card's maximum sustained write speed is 60MB/s, which is the ceiling for constant video streams; prolonged writes at or above this rate will trigger throttling.
