Samsung 990PRO radiator version evaluation: Liugong Fendai has no color

Speed has always been the pursuit of game enthusiasts and professional users. From mechanical hard disk to SATA solid state to NVMe Solid state hard disk , data transmission speed is constantly breaking through. By 2023, PCIe 4.0 has ushered in the era of a hundred flowers blooming, but it is too unprofessional to only look at the sequential reading speed of 7000MB/s.

After more than two years of iteration, Samsung launched a new 990 PRO solid state drive, which reached the peak of PCIe 4.0 with sequential read and write speeds of 7450MB/s and 6900MB/s, and lifted the random performance to a new high of 1400K IOPS and 1550K IOPS, so that users who pursue the ultimate performance experience have once again experienced the feeling of "seeing mountains at a glance".

When the solid state drive breaks the cooling bottleneck, it is like a racing car unlocking the nitrogen and oxygen acceleration. The Samsung 990 PRO heat sink version goes straight to the ceiling of PCIe 4.0, making other brands' PCIe 4.0 solid state drives no longer have the power to fight back. It is really "looking back and smiling, six palaces of pink and black have no color".

one Technology and art of heat dissipation enhancement

In fact, it can be seen from the appearance that the Samsung 990 PRO radiator version is more high-end. It is also a rectangular overall shape. Samsung has a lot of thought on the radiator. The four corners of the bulge can effectively protect the product, and the central part uses the inclined section combination. The overall appearance design has a sense of future.

In terms of details, the Samsung 990 PRO heat sink is a versatile black and red color match. The black main body with red hollow design not only makes the heat sink more beautiful, but also a larger surface area can further improve the heat dissipation effect.

In addition, Samsung has also ingeniously placed an LED light in the center of the heat sink. This LED with RGB light effect can be said to be the finishing touch. Players can customize the light effect and match it with fashionable hardware easily.

In the heat sink and SSD Samsung has used TIM thermal interface materials to further optimize the heat dissipation effect through precise fitting, and combined with the nickel coating on the main controller, so that the 990 PRO heat sink version has no worries about heat dissipation.

Samsung controls the thickness of the 990 PRO heat sink version to 8.2mm, which is thinner than the Samsung 980PRO heat sink version. It is compatible with the PlayStation 5, desktop computers and laptops that meet the PCI-SIGD8 standard. Performance oriented players need not worry at all.

two Flagship configuration of hardware core

Below the heat sink is the core of this SSD. The Samsung 990 PRO heat sink version uses the main control chip developed by Samsung, adopts the 8nm process and low power architecture, optimizes the data path starting from NAND, and further improves the user experience by shortening the processing time through the cache algorithm.

Compared with the 980 PRO, the energy efficiency per watt of the Samsung 990 PRO heat sink version has increased by 50%, and the random read and write performance has increased by 40% and 55% respectively, which is a two-way upgrade.

In addition, 990PRO for 3D rendering, 4K Video editing The load in different scenarios and multitasking environments such as data analysis is optimized to achieve lower latency and faster processing speed, and further reduce power consumption and temperature.

In terms of cache, Samsung 990 PRO heatsink version still uses Samsung's original low-power DDR4SDRAM. The independent cache capacity of 1TB version is 1GB, and that of 2TB version is 2GB, providing more reliable and stable speed.

The core storage part of Samsung 990 PRO heatsink uses Samsung's seventh generation V-NAND TLC flash memory particles. The single chip capacity of 1XX layer can reach 1TB, and the interface is accelerated to 2.0Gb/s. It is the smallest storage unit in the industry at present. Therefore, the 2TB capacity version can only be a single chip, which further improves the compatibility and cooling efficiency.

three Exciting theoretical performance

At the key test link, we prepared a more comprehensive test for Samsung 990 PRO heatsink version. In addition to the conventional benchmark test and high load test, SSD temperature is also an important parameter we consider. After all, temperature plays an important role in the whole system.

From CrystalDisk info, we can see that the rated capacity of 2TB of Samsung 990 PRO heatsink version is 2000.3GB, the transmission mode is PCIe 4.0x4, and the transmission standard is the latest NVMeExpress 2.0, which is also the basic performance parameter.

The maximum continuous read/write speed can directly see the master control and cache performance of the solid state disk Software In CrystalDiskMark, the highest sequential read/write speed of 2TB of Samsung 990 PRO heatsink version is up to 7463MB/s and 6917MB/s, both exceeding the official nominal 7450MB/s and 6900MB/s performance.

Samsung 990 PRO heatsink version 2TB has applied the latest TurboWrite2.0 technology to improve the SLC cache space HDTune The file length of 200GB is set in the file benchmark of Pro. It can be seen that the 2TB write speed of Samsung 990 PRO heatsink version is stable at about 6000MB/s, and the write performance of large capacity files is also very strong.

In the 4K test, the maximum 4K random read of 2TB of Samsung 990 PRO heatsink version reached 1400K IOPS and 1550K IOPS, killing a lot of PCIe 4.0 solid state disks. What many players don't know is that 4K random read-write is more suitable for our daily use scenarios. Sequential read-write is only used when copying a single large file, such as high-definition movies and large game installation packages. Normal browsing of web pages and playing games deal with fragmented files, which need to be addressed by the master constantly, so 4K random can truly reflect the strength of SSD, The 4K random speed of Samsung 990 PRO heatsink version up to 1400K IOPS and 1550K IOPS also proves that this SSD is the real performance king.

four The peak of advanced performance

The benchmark software can be said to reflect the theoretical performance of SSDs, but the load on SSDs is higher in many professional scenarios in actual use. In the advanced test, we chose the IOmeter software to test, further extract the 2TB performance of Samsung 990 PRO heatsink version under extremely severe storage load, record the speed and observe its temperature trend.

First, the 128KB sequential write test lasted for 45 minutes. At the initial stage, the 2TB speed of the Samsung 990 PRO heatsink version remained around 6900Mbps. After 33 seconds, the cache was exhausted. It can be seen that the SLC cache was about 233GB, then dropped to about 1450Mbps and remained stable close to a straight line. Compared with the PCIe 4.0 solid state disk at the same level, the advantages of the heat sink were obvious. The heat sink unlocked the Samsung 990 PRO more effectively.

30 minutes later, Samsung 990 PRO heatsink version 2TB master control Trim executed another 45 minutes of 4KB random writing. From the test data, the rate of 190000~200000IOPS lasted about 350 seconds, then the cache ran out and dropped to 40000 IOPS, and began to climb to 90000~100000IOPS. The final stable value was about 610000~850000IOPS, which was stronger than that without heatsink, This performance is also far superior to that of PCIe 4.0 solid state drives of the same level.

Based on the test results of 128KBQD32 sequential write and 4KBQD32 random write, we can see that the 2TB of Samsung 990 PRO heatsink version has achieved stronger performance improvement, especially in the case of high load for a long time. The 4K random write performance has again created a new high for consumer PCIe 4.0 solid state disk drives.

The temperature test is a top priority for Samsung 990 PRO heatsink version 2TB. In the high load IOmeter test, we recorded the temperature trend of this SSD throughout the whole process, and the test ambient temperature was 28 ℃.

In the standby mode, the temperature of 2TB of Samsung 990 PRO heat sink version is 49 ℃. It starts to rise 5 minutes after the test starts, then reaches 64 ℃. After 30 minutes, it slightly drops to 63 ℃ and remains stable. Five minutes after the test ends, the temperature drops rapidly.

From the test data, the 2TB temperature performance of Samsung 990 PRO heatsink version is very good, far from triggering the dynamic thermal protection mechanism (DTG), which is also the reason why this SSD can perform extremely well under long-term pressure test.
