Hello everyone, I am Qian Wade. The current solid-state market is really crowded, especially after everyone has figured out Pinduoduo and added large coupons, I can hardly understand the price. So today I will test a Pinduoduo that sells very well on the PCIe 4.0 medium speed drive, the Phantom Hidden HV30002TB.

Basic information

The HV3000 of Fantasy Hidden is actually a product series, including the regular version using the Lianyun 1602+Yangtze River 128 layer particles, the Pro version using the Lianyun 1602+Yangtze River 232 layer particles, and even the Ultra version. However, I tested the regular version this time, which should be the best-selling version.

By using FlashID, you can see the main control and granular information. As we mentioned above, the master controller is 1602A of Lianyun, and the particles are 128 layers of Mount Taishan stored in the Yangtze River, with a total capacity of 2048.4GB. Since it is a non buffer HMB scheme, it borrows 32MB of memory capacity.

The HV3000 adopts a single sided particle design, and the front is not covered with self-adhesive, but with metal heat dissipation fins that have heat dissipation effects. I took it off and found that it has a certain thickness.

After uncovering, it can be seen that the total number of particles is 4, so the capacity of a single particle is 512GB. After formatting under Windows, the total available capacity is 1.86TiB.

Next is the minimum 4K random read and write test, and the performance in the empty disk state is still the best, with a read rate of 73 megabits per second and a write rate of 284 megabits per second. Under 50% and 75% occupancy, the performance is still the same as in the empty disk state. This speed is average, and if it's an Intel platform, 4K would be faster.

Finally, the maximum 4K random read and write used by the server is relatively high. In the empty disk state, the read rate is 2561 megabits per second, and the write rate is 3106 megabits per second. The other two occupy the same capacity as the empty disk, with little change.

So from the test results of CDM, we can see that even with 75% capacity occupied, HV3000 still hasn't lost its cache, which is still good for the later user experience.

Actual Write

It can be seen that the size of the SLC cache is around 50GB, and the speed fluctuation after buffering is relatively large, ranging from 1GB to 2.7GB, but most of the time it is in a relatively high-speed position.

However, when I directly copied files from another disk to HV3000 under Windows, the situation was different. The simulated SLC cache size reached around 100GB, but the subsequent write speed remained mostly between 2GB/s and 2.4G/s.

So the strategy of this firmware in an empty disk state is to reduce the simulated SLC capacity, but it is quite characteristic to try to improve the TLC speed as much as possible after buffering.

Write a 953G file while occupying 50% of the capacity and check the write status of the half disk. The SLC cache is still the same as when the disk is empty, with a capacity of around 100GB. However, after buffering, only 100GB of capacity is left for the first TLC direct write, followed by a second segment speed of around 700MB.

This performance is also quite normal. Let's continue to look at writes with 75% capacity usage.

After occupying 75% of the capacity, I wrote a 474G file, leaving only about 30GB of SLC cache. After running out, I thought I would maintain a speed of 700 megabytes throughout the entire process. However, after experiencing a period of low speed, the speed returned to over 1G and fluctuated between 1G and 2G. It seems that the enthusiasm for recycling is still high.

Write stability

After reading the write performance, let's take a look at the stability of the write. Perform a 30 minute QD32128K sequential write test using IOmeter, and the results are as follows. The points written are basically kept within a relatively narrow range, with speed fluctuations mostly around 0.5G, with only a few points deviating significantly.

However, the foundation of the particles in the Lianyun 1602 and Yangtze River 128 layers is placed here, although the fluctuation amplitude is large, it is not to the extent of chaos, and the speed boundary between slow inside and slow outside is still very clear.

Heat dissipation test

I use IOmeter for 15 minutes of 100% sequential reading to test the heat generation of the hard drive.

At a room temperature of 22 degrees, using a thermal imager to test the temperature, it can be seen that the main control of the hard drive quickly reached a high temperature of 97 degrees, and then fluctuated between 96 and 99 degrees, basically not exceeding 95 degrees.

The reading speed during this period is recorded as follows. The reading speed will gradually decrease as the temperature of the main control rises, and the fluctuation amplitude of the speed is set. Each time, it will decrease to a speed of 2.7G per second. After the temperature cools down, it will continue to rise until the next overheating and deceleration.

The temperature of the particles is quite low, with the hottest being 56 degrees and the coolest being 46 degrees. The temperature sensor is relatively low on this side, with the main control reaching a maximum of 69 degrees and the particles reaching a maximum of 50 degrees.

So to achieve performance or long-term stability, it is definitely necessary to install heat dissipation fins.
