Write in front

Has our computer ever experienced slow startup and stuck opening large files in daily work? Especially for productivity users like me who often need to open dozens or hundreds of pictures at one time in Lr, the original mechanical hard disk or SATA solid state can no longer meet my work needs.

However, due to the dynamic changes in the international market, the price of high-speed and high-capacity SSDs is rising, and there is a tendency to reverse the trend of five years ago. Fortunately, the current domestic solid state scheme is becoming more and more powerful. With the continuous maturity of technology and process, the high-speed solid state with domestic master control+domestic particles at this stage is not exported to foreign products in terms of performance.

As the leader in the domestic storage field, Baiwei launched a 2TB PCIe a while ago 4.0X4 full speed high-capacity hard disk NV7200 adopts the mainstream solution of Lianyun MAP1602+long-term storage particles, with the nominal maximum read/write speed of 7200/6200MB/s, and supports the latest NVMe 2.0 protocol, integration of HMB+SRAM, integration of Smart Cache and other technologies, and proper first-line performance. a key Price of 2TB capacity model As long as it is over 800, the price of a single TB is directly back to that of two years ago, which is a cost-effective choice for productivity users at this stage. 

Unpacking suntan

Baiwei NV7200 The package and body of the 2T SSD are eye-catching black gold color matching, which is integrated with its own black PCB and gold finger color. The texture is excellent, which is very suitable for the low-key luxury characteristics of commercial scenes. Baiwei NV7200 The 2TB SSD is also packaged with an installation screwdriver and M.2 screws. Novice can easily get started and complete the installation of the SSD in three minutes.

BV NV7200 2TB solid state disk is a standard 2280 specification, with single-sided particle design. It can be seamlessly compatible with desktop computers, laptops and even PS5, and it is easy to upgrade. On the front of the SSD is a 1mm thick graphene composite thermal conductive sticker, which can effectively reduce the operating temperature. I will also do a high load test in the later measurement to see how the specific heating performance is.

The back is printed with the relevant parameters and SN code of the SSD, so that when we use the motherboard heat dissipation metal armor, we can safely tear off the front heat conduction sticker, but it does not affect the warranty. BV NV7200 solid state disk provides a total of 4 capacity versions from 500GB to 2TB, which makes it convenient for us to select the appropriate capacity according to the needs, and all support a five-year warranty of replacement without repair.

When the heat conduction pad is removed from the hair dryer Dafa, it can be seen that the BV NV7200 solid state disk uses the third generation of 12nm process MAP1602 master control of Lianyun, together with the BV encapsulated long-lived original particles. The 2TB version is a single-sided particle design with a single 500G capacity and no built-in cache.

Performance Experience

After unpacking, we went to the computer to see BV NV7200 What is the real performance of 2TB SSD. The test platform is AMD R9 The productivity platform of 7900X+MSI B650M mortar makes the real efficiency of full nuclear work higher. View hard disk support PCIe using CrystalDiskinfo 4.0X4 channel, NVMe as standard 2.0, supporting S M. A.R.T., TRIM, VolatileWriteCache and other technologies. The room temperature is 24 ℃, and the standby temperature is 38 ℃, which is quite good.

The CrystalDiskMark tests the performance of the BV NV7200 2TB solid state disk when the disk is empty. The continuous read speed is 7325MB/s, and the continuous write speed is 6333MB/s. Alas, this is higher than the nominal speed. The whole reverse virtual label is used.

The results obtained by using TxBENCH test are almost the same as those of CrystalDiskMark.

Ordinary scores may be BV NV7200 The SLC simulation cache of 2TB SSD plays a role, depending on the speed of the ontology or HD Tune Pro test. We read and write 200GB random data files. The writing speed is very stable, and the curve is flat and straight without major fluctuations. The reading speed will decrease slightly after 120GB, but it is still stable at more than 4000MB/s. It can be seen that the performance of the solid-state master is very stable.

Every user is very concerned about whether there will be a great loss of SSD performance when the disk is full. I wrote nearly 1.7TB of learning documents into BV NV7200 After the 2TB solid hard disk, it is tested again with almost full capacity. The sequential read/write speed and 4K random read/write speed are almost the same as those of empty disks, which shows that the master control and software optimization of BV NV7200 SSDs are really hard work.

During the test, I used software to monitor the temperature performance of BV NV7200 2TB SSDs in real time. The measured maximum temperature was only 50 ℃, which was only one drop higher than the standby 38 ℃. Compared with the maximum temperature of slow SSDs at the same speed, it was significantly reduced by 30-50%.

In addition, it is worth mentioning that since the CPU channel bandwidth of my AMD platform Zen4 is 256bit, I can run full PCIe The theoretical maximum of 4.0X4 channels, while the Intel CPU channel bandwidth is 128bit, PCIe The 4.0X4 channel can only run to about 7100MB/s, so it is normal for different platforms to have some differences in scores, but it has little impact on actual use.

Productivity Experience

In terms of actual office experience, I use BV NV7200 2TB solid state disk for personal PS LR and other software have been tested. When we use LR to open more than 400 RAM pictures straight out of the camera, it is very smooth. It is fast forward from the time when we can listen to a song to the time when we can drink tea. In addition, there is no pressure to load these pictures in batches, and it can be done in ten seconds.

PS directly opens five 7008 x 4672 resolution RAM format images for editing. Both loading and exporting after drawing revision are very fast. It's wonderful to replace an old hard disk with a low-cost, high-capacity, full speed solid state disk.

Write at the end

In general, BV NV7200 The price performance of 2TB at the price of 849 yuan is quite good. PCIe 4.0 The super high performance of the first echelon of solid state, the compatibility of all kinds of equipment, and the 5-year warranty for replacement repair are all very valuable. If you want to upgrade your old computer to a reliable, high-performance, well cooled, affordable solid state disk, the BV NV7200 is really the first choice.

Finally, my favorite friend asked for continuous attention. I welcome friendly conversation, accept appreciation, and respect your opinions. If we have any opinions, we can have a frank conversation and fully exchange views, which is conducive to enhancing the friendship between our valued friends. I can't stand the mindless sprays. I hope the keyboard heroes will talk about martial arts.
