Sony Tough rugged SD memory card test, digital photo storage is more secure

Sony Tough rugged SD memory card is mainly used for outdoor photography needs. Let’s take a look at the actual reading and writing data.

Sony recently announced the launch of the Tough series of rugged SD memory cards in August. It is mainly designed for those who often shoot outdoors and hope that the memory card will not be damaged due to unexpected conditions. At the same time, it also maintains the The high-speed transmission characteristics of the SF-G series memory cards allow users to complete the continuous shooting and writing process faster during the shooting process. This time I had the opportunity to get the 64GB capacity version and tested it with α7r III and α7 III respectively to see the strong protection effect and high-speed reading and writing performance of this memory card.

In the past, many users had the impression that SD memory cards were prone to damage during use. , leading to the loss of previously taken photos that have not been copied and saved, or even accidentally denting them, causing the memory card to break, or the memory card cannot be used normally due to high and low temperatures, water immersion, etc.

Perhaps for ordinary users, it would be sad to lose previously taken photos, but for professional photographers, the most important part of the entire shooting process is whether the images can be successfully stored in memory. card, and at the same time, before actually taking out the internal images and backing up the memory card, it is best not to cause damage to the memory card due to any accident, otherwise the overall shooting results will be lost, thus affecting your livelihood.

The appearance of Tough series memory cards is no different from ordinary standard SD memory cards

Therefore, Sony emphasizes that Tough series SD memory cards are filled with epoxy resin. There is no gap in the body, and the anti-write switch that is not commonly used in the original SD memory card is cancelled, so that the memory card itself can be more sturdy, and corresponds to the IP68 rating, can still respond to 72 hours of submersion protection within 5 meters of water, and is resistant to drops. It can withstand bending forces of up to 180N. Basically, it is almost difficult to bend this memory card by hand, unlike ordinary memory cards that will break immediately with just a little force.

In addition to being waterproof and anti-drop, Tough series SD memory cards can also withstand adverse conditions such as anti-magnetic, anti-static, or X-ray irradiation that are detrimental to the internal storage of digital file content, and can even be used under high and low temperatures. Or maintain normal function under high UV irradiation, thus echoing the Tough series brand name.

Adopt an integrated design to increase the strength of the memory card< /p>

Sony has also provided the design of the Tough series SD memory card to the SD Association. It is expected that the design of the Tough series SD memory card will become a public standard, thereby making the SD memory card a more reliable storage medium. In line with the increasing number of camera designs that incorporate anti-drip and dust-proof features, professional workers will have a more secure image recording experience.

In addition, since the Tough series SD memory cards are based on the previous SF-G series, they also retain the usage characteristics of high-speed cards. They adopt the SDXC II specification and are advertised as capable of reading at 300MB per second. and ideal performance of 299MB writes per second.

However, this part still deviates from the actual usage. For example, through the USB Type-C port on the 2018 15-inch MacBook Pro, paired with Apple’s original USB Type-C adapter Using Sony's original SDXC II card reader, the test results were tested through the Mac version of Blackmagicdesign Disk Speed ??Test, reading 259.6MB per second and writing 185.6MB per second.

Using the Mac version of the AJA Video Systems hard drive test program, we obtained performance results of 215MB per second for writing and 271MB per second for reading. The data measured in the Windows version also yielded almost the same results.

The actual reading and writing speed performance will basically vary depending on file size, image resolution, encoding form and other conditions. This time, we measured full 4K resolution, 1GB file size, and 10-bit In the YUV color encoding format, although the final test results did not reach 300MB per second for reading or writing data, it actually has a very fast transmission speed.

If you use a general card reader to access, the actual writing and reading speed will be directly between 80-90MB per second. Therefore, if you want to maintain high-speed access, it is recommended to use it together. The SDXC II card reader launched by Sony can maximize the actual access performance of the memory card.

Only when paired with a card reader of the same SDXC II specification can it support higher access performance

In addition to providing high-speed access and high protection, Sony also provides detection on this memory card The tool "Sony SD Scan Utility" and the rescue software "File Rescue" can recover file contents. The memory card itself provides a 5-year warranty and is branded as "Made in Taiwan" to ensure its quality.

In terms of recommended selling price, the Tough series SD memory cards are more expensive than the previously launched SF-G series, but the price difference is actually not that big, so users can regard the price difference as an upgrade to a stronger protection effect. , to ensure that the captured image content will not cause regrets due to accidental damage to the memory card.
