Panasonic's Features


PROOF7 UHS-I Smooth Video Recording

Has this ever happened to your valuable memories? Did you know that SD cards have a lifetime?
You might want to check the cards you're using.

Use a lot, save it longer. Panasonic SD cards have long-lasting, Tough & Reliable.

Here's why...

Long-Lasting Reason 1: Panasonic uses a long-lasting MLC (Multi-Level Cell) flash memory

Recent advances in camera equipment have changed usage styles and allowed higher-quality images to be captured.

For example, there are now uses like these... High-speed consecutive shots / Video shooting / Interval shooting

When users are able to easily record images with high-quality (large-volume) data, the number of times the data is rewritten to the SD card increases.

When selecting an SD card, the card's capacity is naturally an important factor, but the number of write cycles is also essential.

As the number of rewrites increases, the length of lifetime that data is saved decreases. This kind of use calls for Panasonic's SD cards with MLC flash memory. Compared with TLC (Triple-Level Cell) flash memory, MLC flash memory can be rewritten up to 10 times as much. That means they last 10 times as long.

This image shows the data storage time for MLC and TLC data (when used under the same conditions).

Long-Lasting Reason 3: The Data Protect function prevents data from being damaged

Smart Guard

Error Guard

The number of errors occurring with flash memory increases for reasons such as repeated reading and writing, and if the number of errors passes a certain level, the errors cannot be corrected and data becomes corrupted. Panasonic SDUD / SDUC / SMGA Series have an automatic refresh function, which extends card life by using the Intelligent Controller to automatically refresh data before the errors increase too much to be corrected.

Power Failure Guard

When power is interrupted, the Intelligent Controller automatically retrieves data that was damaged. Besides data that is currently being saved, other data may be damaged when power is interrupted. Panasonic SD cards are equipped with an automatic data retrieve function to preserve your important data.

Data Damage Guard

Smart data writing technology equalizes rewrite frequency on each writing block in order to reduce defect risks. Without smart data writing, data will be repeatedly rewritten in specific areas, thereby damaging those areas. Thanks to Smart Data Writing carried out by the Intelligent Controller, Panasonic SD cards minimize defect risks and provide high reliability.
