When it comes to the mobile SSD industry, Samsung's T7 series can be said to be a "handle" product. With its excellent transmission speed and stability and attractive appearance, it can easily sit in the top three sales of major e-commerce platforms.
Today to evaluate this Samsung T7 Shield using USB 3.2 Gen2x1 transmission protocol, the fastest can reach reading 1050MB/s, writing 1000MB/s, for daily work life data transfer can almost do small files "second transmission", large files can be completed in just a few seconds, and then we will evaluate it in detail.
Appearance: The "tough guy" also needs gentle protection inside
Samsung T7 Shield product packaging using a full-color box design, with detailed product information and instructions on the side, the most eye-catching of which is that the product supports IP65 level dust and waterproof, support 3 meters of drop protection, etc., paving the way for our daily use safety.
The package contains a total of two layers of structure, one layer of the main body of the T7 Shield, and one layer of accessories and manual box. The accessories include a USB Type-C to C data cable and a USB Type-C to A data cable, and the cable quality is good.
T7 Shield has a total of three colors, magic blue, moon curtain mu white, dark night black, the main body uses a rubber shell as protection, we got the moon curtain white version. The surface of the shell has a concave and convex pattern, which on the one hand improves the anti-slip and grip, and on the other hand, there are also heat dissipation considerations. The tactile feel is similar to the common rubber material, and the finger touch will have some damping.
In terms of weight, the T7 Shield is also heavier than the conventional metal version, and the size of the three dimensions is also slightly improved, but it is still a very thin and compact category, and the weight of less than 100 grams is not easy to be detected in the bag, maintaining the consistent portable and lightweight properties of Samsung Mobile Solid.
In terms of protective performance, T7 Shield can withstand about 3m drop situation; it has IP65 level dustproof and waterproof performance, of which IP6X represents 6 levels of dustproof ability, that is, completely prevent dust from entering. The IPX5 shows that it has the 5th level of waterproofing ability, can withstand any angle of low-pressure spray without impact, daily splashing, splashing, cup knocking caused by short-term wetting is not a problem.
This protection capability can ensure that the T7 Shield has a wider range of use scenarios, including outdoor office, outdoor photography and other users who need to use mobile storage in unconventional scenarios.
At the same time, the mobile SSD can also be connected to the mobile phone as a transmission medium, which is very convenient to "expand" the mobile phone.
Performance: Constant blazing speed transmission
The transmission performance of the T7 Shield is still maintained at the level of the T7 flagship level. In terms of interfaces, the Samsung T7 Shield uses a PCIe NVMe interface to achieve the highest speed of a USB 3.2 Gen 2 (10Gbps) interface with a read speed of up to 1,050MB/s and a write speed of up to 1,000MB/s.
This was followed by a series of real-machine tests.
We use the Type-C interface to connect with the computer, after connecting the computer, you can find that the hard disk contains Samsung's original security software, divided into Android, Win, Mac version.
Before testing, we turned on the "high-performance mode" of the removable hard drive, enabling write caching on the device.
The first is the Crystal Disk Mark test, in the test of 1G files, T7 Shield's write speed is 989MB/s, the read speed is 1039MB/s, similar to the official advertisement, while at room temperature of 25 degrees, the temperature of the mobile hard disk at the end of the test is 43 degrees.
The results obtained by the TxBENCH benchmark are not much different from those of the same type, with read and write speeds of 1022MB/s and 993MB/s, respectively. At a room temperature of 25 degrees, the temperature of the portable hard disk at the end of the test is 42 degrees.
In the AS SSD benchmark performance test, the continuous sequential read and write speed of the 1GB data level is 957.14MB/s and 928.42MB/s, although there is less than 10% gap with the official advertised data, but considering the interface, and the impact of temperature on the mobile hard disk, this score can be said to be very eye-catching, better than the ordinary T7.
We used HD Tune Pro for hard disk pressure testing, measured that in the actual write process of 100GB, the hard disk did not have a significant drop in speed, but because the temperature increased and called the dynamic write speed to alleviate the temperature pressure, while the average speed in the later period has been maintained at more than 850MB/s, very good. At a room temperature of 25 degrees, the temperature of the mobile hard disk at the end of the test is 46 degrees.
Finally, we conducted a performance benchmark test in Samsung's own Samsung Magician management software, the measured read and write speed is 880MB/s and 830MB/s, the software can not only be used to view the current capacity of the hard disk, temperature, historical read and write situation, but also for firmware management upgrades, security protection and other functions, in line with the style of the big factory.
Of course, the most important safety features are indispensable. The software supports users to set passwords for Samsung T7. In terms of encryption, the Samsung T7 uses AES 256-bit hardware encryption. In this hardware encryption method, there is no need to worry about the software being cracked to cause file information leakage, and the use of AES 256 encryption algorithm for encryption, it will take at least hundreds of years to crack the contents of the mobile hard disk.
Summary: Samsung T7 Shield has upgraded a certain transmission performance and all-round protection performance on the basis of T7, which can not only allow users to get a fast transmission experience, but also make users' data more secure. It is lightweight and portable, but also achieves the advantages of strong performance, strong compatibility, strong thermal performance and data security. It's ideal for users who need to go out and carry their mobile hard drives frequently. Excellent waterproof and dustproof ability allows users to easily use the portable hard disk in some special outdoor scenes, such as beach shooting. The anti-fall ability is reflected in all aspects of daily life, even if you sometimes do not pay attention to the drop, do not have to worry about data security!
