16 GB microSDHC Class 4 10-pack

This bundle supplies ten microSDHC cards each rated at 16 GB with a Class 4 speed rating. A single SD adapter and a USB card reader are included for immediate use. The pack suits buyers who need multiple low-cost cards for standard-definition capture or bulk distribution.

Class 4 speed ceiling

Class 4 guarantees a minimum sustained write of 4 MB/s, with the manufacturer citing up to 20 MB/s read and 5 MB/s write. This throughput handles standard-definition video and still photography but will bottleneck full HD or higher bit-rate recording. The UHS-I bus is present but the Class 4 rating remains the limiting factor for sustained writes.

16 GB per card headroom

Each 16 GB card holds roughly four hours of standard-definition footage or thousands of compressed photos. Capacity runs out quickly with high-bit-rate formats or extended sessions. The ten-card bundle provides aggregate storage but no single card exceeds 16 GB, so users needing continuous large files must swap cards frequently.

Questions about this item

Should I choose the 4 GB, 8 GB, 16 GB or 32 GB version?

The 16 GB cards in this pack give you ten cards and a reader; the 4 GB, 8 GB and 32 GB models are sold separately.

What does the 20 MB/s read speed mean when I put the card in my camera?

It is the maximum sequential read rate the card can sustain; real-world transfer will be lower depending on the device and file sizes.

The card is labelled UHS‑I — what does that limit in practice?

UHS‑I defines the bus interface; this card runs at Class 4 speeds of 20 MB/s read and 5 MB/s write within that bus.
