Overview

The Ohm PCGEAR PC-MMS32G-K sits in the practical, no-frills corner of the microSD market. It is a 32GB microSDHC card carrying Class 10 and V10 speed ratings alongside UHS-I and Full HD compatibility. Ohm quotes a maximum read speed of 70 MB/s and frames the capacity in relatable terms: roughly five hours of Full HD video, or approximately 4,800 photos captured at 18 megapixels. That makes it a sensible companion for compact cameras, dashcams, and older phones rather than a card chasing 4K benchmarks. The standout claim is durability. The card body is compliant with JIS Waterproof Protection Grade 7 (IPX7), which Ohm defines as surviving still water at about one meter for roughly 30 minutes.

On the construction side, the card is tiny and light, measuring 11 x 15 x 1.0 mm and weighing around half a gram. It arrives with a genuinely useful kit: an SD conversion adapter with a lock switch to prevent accidental writes, a storage case, and a warranty card. A CPRM protection function handles copyright-protected recordings. Ohm is candid about limitations too, noting the IPX7 rating does not guarantee complete waterproofing and that the company neither recovers nor restores lost data. For a buyer who wants an affordable, rugged card for everyday Full HD capture, those honest caveats are worth reading before purchase.

Frequently Asked Questions

Ohm rates it at approximately five hours of Full HD video, or about 4,800 photos captured at 18 megapixels, though actual counts vary with bitrate and file settings.
The card body meets JIS Grade 7 (IPX7), meaning it can sit in still water at about one meter for roughly 30 minutes. Ohm stresses this does not guarantee complete waterproofing.
Yes. It ships with an SD conversion adapter that also has a physical write-protect switch, so you can slot it into full-size SD readers and lock it against accidental erasure.
Ohm lists a maximum read speed of 70 MB/s with UHS-I and Class 10/V10 ratings. No official write speed is published, so sustained recording performance is not specified.
It is rated Class 10 and V10 with Full HD compatibility, so it targets 1080p capture rather than demanding 4K workloads. Heavy high-bitrate recording is outside its stated design.
No. Ohm states it does not recover or restore data and is not responsible for erased or damaged files, so keeping independent backups of important data is recommended.
