For Zhizhi, I believe everyone is quite familiar with it, and its solid-state drive products have a pretty good reputation. Recently, YMTTC has begun to lay out the memory card product line and officially released two new products, the Zhitai PRO professional high-speed memory card and the Zhizhi Endurance high-durability memory card. We also got the new product, let's experience it with you.
Friends who often use memory cards know that outdoor sports, shooting and other use environments are changeable, and indoor monitoring and other scenarios need to run for a long time, so the reliability of the memory card itself is very important, after all, data is priceless. In this regard, the two new products use the original flash memory particles of the YMTC crystal stack ®Xtacking® architecture, and both have multiple protection designs such as cold resistance, heat resistance, water resistance, impact resistance, shock resistance, drop resistance, anti-static, X-ray resistance, and 10K plugging and unplugging, so as to protect data security in an all-round way.
As can be seen from the series naming, the two new products have completely different positioning and usage scenarios, which is also conducive to users to make more suitable choices.
The PRO professional high-speed memory card is aimed at professional users, featuring high performance and equipped with a power-off protection mechanism, even if the camera suddenly loses power during recording, it can also store video footage completely, so as not to miss any wonderful moments. As can be seen from the package logo, the sequential read and write speeds of this memory card reach 170MB/s and 120MB/s respectively, and support U3, V30, A2 speed levels, which are mainly suitable for 4K recording needs of professional cameras, drones, action cameras and other devices. Of course, it is also possible to expand the storage space of the gaming handheld.
The PRO series enjoys a lifetime warranty, with a total of 64GB/128GB/256GB/512GB four capacities, and all systems are equipped with original SD card adapters as standard, of which 256GB/512GB comes with an additional storage box.
Here's the first test of the read and write speed of the 512GB memory card of the Zhizhi PRO series with a USB 3.2 card reader. CrytalDiskMark measured that the read speed exceeded 170MB/s, and the write speed also exceeded 120MB/s.
In the actual writing file test, we can see that the writing curve is very stable, and it has been maintained at about 122MB/s, and there is no slowdown in the middle of the process.
Then test the video shooting on the computer, Sony A7S3 turns on XAVC S 4K mode, and the Zhizhi PRO series can meet the recording needs of 4:2:2 10bit 200Mbps.

↑ 4K video playback is smooth
In terms of compatibility, the PRO high-speed card has passed the compatibility test, and many devices such as Fujifilm GFX 50 SII, Sony A7S3, and DJI Osmo Pocket have been tested here, and they can all be used normally.
As for the Endurance high-endurance memory card, it is mainly used for home security cameras and driving recorders, which are scenarios that need to be written for a long time. The specific specifications are to support 7*24 hours of all-weather recording, and uninterrupted video recording can reach 60,000 hours.
Although it is a device used for intensive recording, there are requirements for read and write speeds. After all, whether it is monitoring or dash cams, many of them have gone to 4K resolution.
Therefore, the Endurance series supports U3, V30, and A2 speed levels, with a total of 64GB/128GB/256GB capacities. The measured theoretical speed read and write are 95MB/s and 86MB/s respectively, which can well meet the needs of 4K monitoring and dash cams.
However, the most important thing for memory cards used for monitoring and recorders is the reliability of continuous reading and writing.
↑Xpeng G6 tested, 256GB can keep driving records for more days
Because like today's smart cars, in addition to driving, it is necessary to record the data of multiple cameras. Sentry mode may also be turned on when parked, and the screen recording can be almost uninterrupted. Therefore, it is particularly important that Endurance supports 24/7 recording, and can record up to 60,000 hours.
