Three-card kit with reader

This pack contains three SanDisk SDHC cards, each offering 16 GB of storage, plus a single reader. The cards use the full-size SD form factor and carry a Class 4 speed rating under the SD 2.0 specification. They are suited for photographers and general users who need multiple affordable cards for everyday shooting or file transfer.

Class 4 sustained write speed

Class 4 guarantees a minimum sustained write rate of 4 MB/s, which keeps power draw low and produces no audible noise during operation. The reader connects via a standard USB interface, adding no active cooling requirement. Normal use stays well within the thermal limits of cameras, laptops and tablets that accept SDHC media.

Replaces slower or single cards

The bundle upgrades from a lone lower-capacity card or from media that cannot sustain Class 4 writes, giving extra space and a reader in one purchase. It is not for users who need UHS-I or video-speed-class performance for 4K recording, nor for workflows that demand faster offload rates than Class 4 provides.

Questions about this item

How do I insert the full-size SD cards into the included reader without damaging the contacts?

Align the label side up and the bevelled corner first, then slide the card straight in until it clicks; forcing it at an angle bends the gold contacts.

Will the write-protect switch on each 16 GB card wear out after repeated use?

The mechanical slider is rated for thousands of cycles; under normal handling it lasts the life of the card, but avoid flicking it with fingernails to prevent early fatigue.

At what sustained write speed does the Class 4 rating become the bottleneck during long video clips?

The Class 4 guarantee is 4 MB/s minimum sequential write; once the camera buffer fills, recording drops to that floor regardless of burst capability.
