Samsung’s EVO + microSD card, launched last year, was once widely praised by consumers and won the PConline 2015 Award. With this momentum of success, Samsung launched a new EVO Plus 256GB microSD card this year. Last year’s EVO + microSD card had a maximum capacity limit of 128 GB, which is not enough in this era of 4K video recording and shooting. Consumers keen demand for high-capacity storage devices has led to Samsung’s 256GB EVO Plus microSD card today – and it comes out with Samsung’s current top 48 unit-level V-NAND flash technology. So how strong is it in continuous writing and reading? Can it bring users a better user experience? Let’s take a look at it right away.
The power of technology is awesome. I want to have a 128MB microSD card for mobile phone storage capacity expansion, almost ten years later, the small microSD card has developed to carry 256GB capacity. Samsung’s ability to break through capacity limits, again and again, is attributed to its use of 3D V-NAND flash technology. Simply put, it is through 3D stacking technology that more CELL units are encapsulated in a very small area. The more advanced the process, the higher the storage density and the larger the flash memory capacity that can be achieved. Samsung, which has the world’s leading flash technology, is admirable in this respect
Samsung EVO Plus 256GB microSD card is not different from the previous microSD card in appearance, but the improvement of injection molding process can be seen in detail. It happens that I have another 16GB Samsung memory card on my hand. When they are put together and compared, it is obvious that the surface of Samsung EVO Plus 256GB microSD card has a better granular texture. Grades are quickly distinguished. I guess this coating should contain a lot of protective technology.
Popular Science Time: Here I would also like to remind readers that the capacity of hardware manufacturers is based on decimal system (1GB = 1000MB), and our computer recognizes it according to binary system (1GB = 1024MB), which is why the microSD card is 256G and actually only 238G, which is the same. And the capacity range of SDXC is between 64G and 2TB. The default format is exFAT, which is different from the FAT32 default format of SDHC.
Storage cards are of course bought for use rather than for appreciating the look. Samsung officially advertises a write speed of 90MB/s and a read speed of 95MB/s, which is so high I/O performance that it is countless in the microSD card industry. Next, I will use two well-known speed measurement software ATTO Disk Benchmarks and Crystal DiskMark to test their actual performance. The author uses a computer with USB3.0 interface and a card reader. The theory will not have a bottleneck effect on the test speed.
From the actual test, the speed of writing and reading is very close to the official publicity speed. It seems that extremely fast writing and reading is absolutely true, for a microSD card is the best! Samsung EVO Plus 256GB microSD card focuses on large capacity, long-term recording, and storage without any pressure. For example, when I use the Samsung Galaxy S7 edge mobile phone to record UHD (3840 *2160, 30fps) video, the file capacity of 1 minute and 11 seconds is 408MB, that is to say, as long as the writing speed of flash is faster than 5.74MB/s, it can meet the shooting needs.
So the most important thing for the 4K video captured by the small sensor mobile phone is the storage capacity! The capacity of 256GB is enough to play for a very long time. The author thinks that Samsung EVO Plus 256GB microSD card is more suitable for the digital single-TV camera with higher picture quality requirement to shoot 4K video with a higher bit rate. After all, the writing speed of nearly 90MB/s is really a bit of a waste when it is used on mobile phones. If you have a need for a large capacity microSD card, don’t expect to buy two EVO Plus 128GB microSD cards (written about 20MB/s) to play 256GB roles – their writing speeds are very different.
Evaluation summary
Samsung EVO Plus 256GB microSD card shows us that finger-sized flash memory can have up to 256GB of “horror” capacity, which is amazing. Choose a good SD card because you don’t need to consider restore deleted pictures SD card. Its continuous reading and writing performance is close to 100 Mbps, which is absolutely the strongest performance for microSD/SD card at present. It is undoubtedly the best flash memory choice for friends who need HD recording and video recording.
