4. Full platform compatibility, supporting PC/Mac, iPhone15/Android smart phones, tablets PS5 And professional broadcast camera and other equipment.

one Low profile luxury design Physical protection Buff bonus

Samsung T9 mobile solid state drive adopts a new cover design, demonstrating a full sense of power. The set up photos of the product are displayed in the main black color, and the model of the product is marked in bold large font in the lower left corner, and the reading speed of 2000MB/s and the capacity of 2TB are marked in the lower right corner (T9 includes 1TB, 2TB and 4TB).

Samsung T9 mobile solid state drive has a lightweight figure of 88x60x14mm and a light weight of only 122g, which is equivalent to the previous star product T7 Shield, and can be easily stuffed into the pocket or backpack interlayer. The rubber surface adopts a new curved diagonal shape, and there is a "SAMSUNG" brand logo at the lower right of the front. The pure black color matching with luxurious carbon fiber lines looks calm and grand, and has excellent grip and anti-skid effect.

As the first product of the new series, Samsung T9 emphasizes the design concept of "adding luxury while being durable". There is a "Portable SSD T9" product logo on the top right of the back. Although Samsung does not emphasize "Shield", its physical protection is still excellent. When the high elastic rubber shell lands, it can disperse the impact through deformation. The internal integrated aluminum frame, A high-strength "roll cage" has been built for the core electronic components, which has a fall protection capability of 3 meters.

It is worth mentioning that the unique structural design of Samsung T9 has its own unique features in terms of heat control. The rubber shell has low thermal conductivity, which can prevent heat convergence at the physical level. It perfectly solves the problem of high heating during continuous reading and writing of high-performance mobile solid state disk, and avoids low-temperature burns.

Samsung T9 has an integrated body. Except for the USB Type-C data interface, the top has no holes or slots. The indicator light is also hidden under the cover.

The bottom is marked with the product model, capacity, working voltage and current, S/N code and various certification information.

Samsung T9 is equipped with the current mainstream Type-C interface, which has excellent full platform compatibility. The Type-C to A and Type-C to C data cables that come with the machine can easily transfer data between PC/MAC, Apple iPhone 15/Android smartphones and tablets, and can even connect professional cameras to shoot from mirror to mirror, avoiding the trouble of frequently changing memory cards.

The indicator light of Samsung T9 has a variety of statuses. The blue light is always on during idle time, and will go out if there is no operation for a long time; It will flash blue when data transmission is completed, and it will be always blue; When the safe push is performed in the operating system, it will flash red, and can be safely removed after it is turned off.

two Benchmark 2GB/s "small target" achieved

The 4K/8K video materials with hundreds of gigabytes of capacity, whether transferred to the computer for editing or transferred from the computer for backup, have put forward higher requirements for the performance of mobile storage devices. Samsung T9 not only uses high-performance core components, but also supports the high-speed USB3.2 Gen2x2 standard with Type-C interface. The 4TB capacity version can achieve a read/write speed of up to 2000MB/s, compared with Samsung T7 Series has basically doubled the upgrade, and the read/write speed of 1TB and 2TB capacity versions has also reached 2000MB/s and 1950MB/s.

The Samsung T9 we tested is a 2TB version. Crystal lDisk info shows that its actual capacity is 2000.3GB, using UASP NVMe transmission mode. UASP is a new transmission protocol developed by USB-IF, which can increase the transmission speed of mobile storage devices by up to 20%, and reduce CPU utilization, data delay and waiting time.

In the Crystal Disk Mark test, the sequential read/write speed of Samsung's T92TB capacity version reached 2053.42MB/s and 1970.13MB/s, both of which slightly exceeded the nominal values of 2000MB/s and 1950MB/s. The powerful performance not only meets the performance requirements of video content creators and game players for high load storage, but also directly Video editing , there is no need to transfer the material to the computer, which reduces unnecessary steps and further improves work efficiency.

ATTO Disk Benchmark It is a commonly used mobile storage device test Software , you can test the performance of storage devices in different size packets. According to the actual measurement, the 4KB file read/write speed of Samsung T9 has reached 78.65MB/s and 152.41MB/s respectively; With the increase of the size of the test file, the read/write performance is also growing. From 256KB, the read/write speed has exceeded 1.5GB/s and 1.3GB/s. After 512KB, the read/write speed has exceeded 1.9GB/s and 1.7GB/s, which means that the Samsung T9 is very efficient in accessing large files such as video materials.

In order to improve the continuous file transmission performance of solid-state storage devices, it is a common practice in the industry to use some spare capacity to simulate SLC to create a cache, which is known as SLC cache. This part of the capacity can provide the highest performance. Samsung named it TurboWrite technology. When storing data, first write the data to the cache at the fastest speed, and then move the data to the regular storage area in idle time, to ensure that users can experience faster writing speed during use.

In the old test software HD Tuen Pro, we asked Samsung T9 2TB When 200GB data is written, the write speed initially remains around 1750MB/s. When the SLC cache is full, the "buffer speed" is 900-1000MB/s, which is even better than some PCIe NVMe M.2. The test results show that the TurboWrite space of Samsung T9 2TB version is about 80 GB, which basically conforms to the nominal value of 88GB. The TurboWrite space of the 4TB version is more than 180GB, and it can even write eight 1-hour HEVC encoded Netflix series video files at full speed.

three File read/write measured USB 3.2 Gen2x2 performance improved significantly

In the benchmark test of PCMARK10 data disk, we will continue to write 15GB data to Samsung T9, and visually display it in numerical form. The final score is 1081 points, the bandwidth is 165.13MB/s, and the average access time is 148us. Compared with the USB3.2 Gen2 mobile solid state disk, the performance is significantly improved.

Due to the limitation of the Windows system resource manager, the ultra high-speed removable storage device will deviate from the benchmark when transferring data across disks. In the actual file transfer test, we copied a 22GB file from Samsung T9 to the desktop, and the reading speed can reach more than 1.5GB/s in the stable phase.

Then copy the same file from the desktop to the Samsung T9, and the write speed in the stable phase reaches more than 1.1GB/s, which is significantly higher than the common 700MB/s of the USB3.2 Gen2.

four Excellent efficient energy-saving heating control

As a high-performance, high-capacity solid-state mobile storage device, Samsung T9 often transmits data between portable devices such as laptops, professional cameras, smart phones, etc. The POWER-Z tester test shows that the peak voltage and current of Samsung T9 during high-intensity sequential writing is 4.73V 1.33A, and the conversion success rate is about 6.2W (considering the voltage drop of serial cables and test instruments, the actual value should be about 6.6W); The idle voltage and current is 5V 0.13A, and the conversion success rate is only 0.65W. The lower power consumption is very friendly to the battery life of these devices.

In terms of heat control, Samsung T9 not only uses core components of more advanced manufacturing processes, but also uses efficient thermal interface materials inside the metal frame to assist in heat dissipation, so as to maintain a scientific and reasonable internal temperature. Even if it is used continuously for a long time, it always maintains peak performance and avoids data loss. After 40 minutes of sequential write test at 26.9 ℃, the internal sensor of Samsung T9 shows that the maximum temperature is only 57 ℃. After the test, the temperature begins to fall back gradually.

For safety reasons, the international product safety standard for low-temperature combustion (IEC62368-1) stipulates that the maximum material temperature of metal must be lower than 50 ° C and the maximum material temperature of rubber must be lower than 60 ° C to prevent the risk of low-temperature burns. According to the temperature measuring gun, the surface temperature of Samsung T9 is 27.3 ℃ at 26.9 ℃. After 40 minutes of sequential writing test, the maximum surface temperature is only 56.4 ℃. Fully comply with this safety regulation. Even if you hold it in your hand, it is just a feeling of warming your hand, so that users can use it with confidence.

five Good compatibility iPhone 15 expansion gospel

In terms of compatibility, Samsung T9 adopts the current mainstream Type-C interface, which is suitable for PCs, Android smartphones, tablets PS Game consoles and professional cameras. It is worth mentioning that Apple's latest iPhone 15 series smart phones fully use Type-C interface, and through actual measurement, T9 can be perfectly recognized when connected to iPhone 15 Pro Max.
