16 GB microSDHC Class 4 bundle

This pack contains five 16 GB microSDHC cards rated Class 4, each supplied with a full-size SD adapter and a protective plastic case. A single USB card reader is also included for direct computer access. The bundle suits buyers who need several low-cost cards for basic storage tasks.

Class 4 write speed and adapter flexibility

Class 4 guarantees a minimum sustained write rate of 4 MB/s, which is adequate for standard-definition video, documents and music files. The supplied SD adapters let each micro card fit full-size SD slots in cameras, laptops or card readers. The USB reader adds a simple plug-and-play option without extra cables.

Upgrading from 2 GB microSD or older media

These cards replace the original 2 GB microSD format and lower-capacity SD cards, offering more space in the same physical size. The jump is worthwhile when a device supports the microSDHC standard and the workload does not demand faster sequential writes. Buyers needing higher write speeds for full HD or burst photography should look elsewhere.

Questions about this item

Does the Class 4 rating cap the write speed at 4 MB/s for these 16 GB microSDHC cards?

Yes. Class 4 guarantees a minimum sustained write speed of 4 MB/s, so the cards will not write faster than that rating under the SD specification.

What physical slots and adapters are needed to use the cards in a full-size SD device?

Each microSDHC card fits into the supplied SD adapter, which then inserts into any standard SD slot; the bundle includes five adapters and individual plastic cases.

How should the USB reader be connected for the first use, and what common step is missed?

Plug the reader into a USB port, insert a card, then wait for the operating system to mount the volume before opening files; skipping the mount wait causes read errors.
