This year, storage powerhouse Crucial launched its second PCIe 5.0 SSD product, the Crucial T705 PCIe 5.0 NVMe SSD. The flagship-level positioning will become a new choice for many high-end users to build a computer.
The Crucial T705 PCIe 5.0 NVMe SSD can be seen as an upgrade to the Critical T700. What are the differences between these two SSDs, the author has listed a comparison table, and you can see it at a glance.
First of all, in terms of performance, the Crucial T705 PCIe 5.0 NVMe SSD uses an upgraded version of Phison's PS5026-E26-52 controller chip to achieve faster transfer speeds. In addition, the Crucial T705 PCIe 5.0 NVMe SSD is available in a limited edition. The regular cooling version uses a black cooling vest, while the limited edition uses a white cooling vest, giving users more options for the appearance and color.
The Crucial T705 PCIe 5.0 NVMe SSD is also available in 1TB, 2TB, and 4TB capacities. Note that there is a difference in speed between each capacity version, with the 2TB version being the fastest of the three capacity versions. In this evaluation, the author chose a 2TB capacity cooling version.
Product appreciation
The front of the box with the Crucial T705 PCIe 5.0 NVMe SSD shows the version and model number of the SSD and the maximum transfer speed up to 14,500 MB/s.
The back of the box introduces the main selling points of this SSD in multiple Chinese languages: up to 2 times faster than PCIe 4.0 and 4 times faster than PCIe 3.0; Backward compatible with PCIe 4.0 and PCIe 3.0; Integrated heat sink for powerful performance.
There are not many accessories in the box, only a product manual.
The Crucial T705 PCIe 5.0 NVMe SSD Thermal Edition has much the same exterior as the Critical T700 Thermal Version, with a black thermal vest.
M.2 interface, supports PCIe 5.0, and is backward compatible with both PCIe 4.0 and PCIe 3.0.

The SSD's thermal vest is made of aluminum and nickel-plated copper. The size of the cooling vest is relatively large, and users need to pay special attention to the installation space on their computer motherboard before purchasing and using it.
The thermal vest is marked with the make and model of this SSD.
The 2TB capacity version of this SSD is designed with PCB double-sided storage chips. The back of its PCB is also covered with a heat dissipation vest. In addition, the back of the PCB is affixed with the product nameplate of this SSD.
The Crucial T705 PCIe 5.0 NVMe SSD is powered by an upgraded version of Phison's PS5026-E26-52 controller.
At present, Phison's official website only provides the product introduction of the old PS5026-E26-52 main control chip, and does not provide the product information of the upgraded PS5026-E26-52 main control chip.
The flash memory chip of this generation has not changed, and Micron's 232-layer 3D NAND is still used, which can provide high-speed data input/output (I/O) speeds of up to 2.4GB/s.
Performance demonstration
Next, the author has assembled a Core 14th Gen desktop platform to test the Crucial T705 PCIe 5.0 NVMe SSD 2TB on the computer.
Note that this test platform is in a bare metal state and does not have a chassis.
CrystalDiskInfo information for this SSD
Crucial T705 PCIe 5.0 NVMe SSD 2TB CrystalDiskInfo information. When powered on, the actual capacity of this SSD is about 1863GB.
(1) The performance of the hard disk in the empty state
CrystalDiskMark
The Crucial T705 PCIe 5.0 NVMe SSD 2TB delivers over 14,100 MB/s sequential read performance and 12,300 MB/s sequential write performance.
HD Tune Pro (300GB Hybrid File Transfer)
In this test, the cache will be out when it exceeds 165GB, and the write speed will drop to about 5000 MB/s, and the read speed will fluctuate between 2500~7500MB/s.
(2) Performance at 50% space occupancy of the hard disk
CrystalDiskMark
At this time, the Crucial T705 PCIe 5.0 NVMe SSD 2TB is still capable of exceeding 14,100 MB/s sequential read performance. However, sequential write performance degraded significantly, dropping to about 7658 MB/s.
HD Tune Pro (300GB Hybrid File Transfer)
When the write operation is performed at 50% space usage, the cache will be released when it exceeds 80GB, and the write speed will be greatly attenuated, and the read speed will be stable in the range of about 3000~2500 MB/s.
(3) Performance of the hard disk at 80% space occupancy
CrystalDiskMark
At this point, the Crucial T705 PCIe 5.0 NVMe SSD 2TB has severe sequential read performance and sequential write performance degradation.
HD Tune Pro (300GB Hybrid File Transfer)
When the space usage is 80%, the cache will be released when it is close to 30GB, and the write speed will be greatly attenuated. The read speed is maintained at about 2500MB/s.
Based on the above measurements, the performance of the Crucial T705 PCIe 5.0 NVMe SSD 2TB will be significantly degraded as the disk usage increases.
Fly in the ointment: The heat generation is very large, and you need to pay attention to ventilation and heat dissipation
Through the past few days of testing the Crucial T705 PCIe 5.0 NVMe SSD 2TB, the author found that this SSD has a very obvious problem, that is, it generates a lot of heat when running at higher loads.
For example, if you write about 500GB of files to this SSD, the temperature of the SSD will quickly exceed 80°C, according to the monitoring of CrystalDiskInfo and HWiNFO. Once the temperature exceeds 80°C, the SSD will experience instability and sometimes write interruptions.
The author has consulted many review articles at home and abroad, and many media have pointed out that this SSD has a serious problem of heating. Therefore, for those who are interested in buying this SSD, it is important to ensure that the inside of the computer case is ventilated and heated.
The Crucial T705 PCIe 5.0 NVMe SSD is also available in a non-cooled version. According to the results of this test, the non-thermal version of this SSD must be equipped with a heatsink.
Product Summary:
Through this review, the author believes that the Crucial T705 PCIe 5.0 NVMe SSD is a flagship hardware with clear advantages and disadvantages.
The advantage is that it is the flagship product of the PCIe 5.0 SSD, and the performance is really strong. The downside is that this SSD heats up a lot when operating under higher loads. Although the cooling version comes standard with a larger cooling vest, the heat dissipation effect is not satisfactory. For users with strong hands-on ability, the author suggests that you can modify the heat dissipation vest of this SSD to better play the powerful performance of this SSD.
Well, that's all for this review, I hope it can help you.
