digital storage

The listings show capacities of 32 GB, 64 GB, 128 GB, and 256 GB.

Reported transfer rates vary widely — the listings include figures such as 3 MB/s, 30 Mbps, 100 Mbps, 130 Mbps, 180 MB/s, and up to 1050 MB/s.

Descriptions mention waterproofing, shockproofing, X‑ray resistance, temperature resistance, and—in one listing—JIS IPX7 waterproof certification plus resistance to static and X‑ray exposure.

Several microSD descriptions reference the Application Performance Class 1 (A1) rating and, in one case, list A1 IOPS figures such as 1500 read IOPS and 500 write IOPS.

Included microSD‑to‑SD adapters allow a microSD card to be used in devices with standard SD slots, enabling broader compatibility without altering the card's specifications.
