SanDisk Ultra 32GB microSDHC Memory Card + SD Adapter

App Performance

A1-Rated for Android

The A1 App Performance Class guarantees a minimum of 1,500 read IOPS and 500 write IOPS — the random-access figures that matter when Android runs apps directly from the card rather than just storing files on it. In practice that means apps moved to the card with Android’s adoptable storage open quickly and stay responsive, where an unrated card of the same capacity would stutter. For an entry-level phone or tablet that shipped with 32GB or 64GB of internal storage, this is the cheapest meaningful upgrade available.

Speed

98MB/s Reads, U1 Sustained Writes

Read speeds of up to 98MB/s make offloading a card full of photos a matter of seconds rather than minutes — roughly twice the pace of older Class 10 cards. On the recording side, the UHS Speed Class 1 (U1) rating guarantees a sustained minimum write of 10MB/s, which is exactly what Full HD 1080p video capture needs to run without dropped frames. Photos, screen recordings and everyday file transfers all sit comfortably inside that envelope.

Durability

Built to Survive, Adapter Included

SanDisk rates the Ultra as waterproof, temperature-proof (-25°C to 85°C), shockproof and X-ray-proof, so a trip through the washing machine or an airport scanner is an anecdote rather than a data loss. The included full-size SD adapter is more than a throw-in: it turns the microSD into a standard SD card for compact cameras, laptop card slots and desktop readers, so one card covers both your mobile device and your computer workflow.

Right choice if you…

✔ Want to expand a budget Android phone or tablet with app-capable storage
✔ Record in Full HD 1080p — camera, action cam or screen capture
✔ Need a boot card for a Raspberry Pi or other single-board computer
✔ Keep spare cards for e-readers, MP3 players, 3D printers or handheld consoles
✔ Want the included SD adapter so the card also works in laptops and cameras

Consider something else if…

✖ You shoot 4K video — the SanDisk Extreme PRO range is built for it
✖ The card will record 24/7 in a dash cam or CCTV — choose SanDisk High Endurance instead
✖ 32GB is tight for a large media library — the SanDisk Ultra 64GB costs little more per gigabyte

Frequently Asked Questions

What does the A1 rating actually mean?

A1 is the SD Association’s App Performance Class 1: the card guarantees at least 1,500 random read IOPS and 500 random write IOPS. Random access is what app launching and app storage depend on, so an A1 card stays responsive when Android runs apps from it — something sequential speed ratings like Class 10 say nothing about.

Is microSDHC different from microSDXC — will it fit my device?

Physically they are identical. SDHC covers capacities up to 32GB and SDXC covers 64GB and above. Any device with a microSD slot made in roughly the last fifteen years supports SDHC, so this 32GB card is actually the safer pick for older cameras, MP3 players and printers that cannot read SDXC cards.

Can it record Full HD video reliably?

Yes. The U1 rating guarantees a sustained write speed of at least 10MB/s, and Full HD 1080p video typically needs well under that. For 4K recording you would want a U3/V30 card such as the SanDisk Extreme PRO — 4K bitrates can exceed what U1 guarantees.

How much usable space does a 32GB card really have?

Around 29.1–29.7GB once formatted, which is normal for all memory cards: manufacturers count 1GB as one billion bytes while operating systems count in binary, and the file system itself reserves a little space. The card ships formatted FAT32 and works out of the box in Android, Windows, macOS and Linux.

What does bulk packaging mean for this card?

The card and its SD adapter arrive brand new and unused in plain protective packaging rather than a retail blister card. The product itself is identical — bulk packaging is how memory cards are supplied to system builders and resellers, and it is part of how we keep the price down.
