SanDisk 8GB microSDHC Class 4 UHS-I 50 pack with SD adapters, cases, reader

8 GB microSDHC Class 4 cards for basic storage

This pack contains fifty 8 GB microSDHC cards rated Class 4 with UHS-I support. Each card includes a full-size SD adapter and a protective plastic case. A single USB reader is also supplied so the cards can be accessed from a computer without a built-in slot. The bundle suits users who need many low-cost cards for simple recording tasks.

Sustained write speed of 5 MB/s with Class 4 rating

The Class 4 rating guarantees a minimum sustained write speed of 5 MB/s, which is the figure that matters for continuous recording rather than short bursts. Read speeds reach up to 20 MB/s when the host device supports UHS-I. Cards operate reliably across a temperature range of -25 °C to 85 °C and are rated water proof, shock proof, vibration proof, X-ray proof, magnet proof and impact proof.

Replaces smaller or slower cards

The 8 GB capacity and Class 4 speed step up from lower-capacity cards or older Class 2 media when recording standard-definition video or storing photos on point-and-shoot cameras, game consoles, smartphones, tablets and similar devices. The jump is worth it when you need more space per card and a guaranteed minimum write rate for uninterrupted recording. Buyers who need high-bitrate 4K video or rapid burst photography will find the sustained write speed insufficient.
