Nvme, the full name of “non volatile memory express”, is a communication interface and driver, which can make full use of the higher bandwidth provided by PCI, so as to provide more powerful performance and efficiency. Because nvme can directly communicate with the system CPU, and is specially designed for solid-state hard disk, it eliminates the storage performance bottleneck on the system, and has been loved by the majority of consumers since it came out.
It is necessary to ensure the quality and life of particles; At the same time, the after-sales service of large factories is better than that of other small factories. Second, buy on demand. The flagship gen4 has good performance, but it’s expensive and hot, so it’s suitable for high-end players; However, the products with slower speed, higher cost performance and larger capacity are obviously more suitable for the majority of consumers.
Recently, Kingston, the world’s largest supplier of solid-state drives, has launched a new entry-level nvme high-speed solid-state drive, nv1m.2nvme. How about the performance of this entry-level nvme high-speed solid-state drive, which is very suitable for laptop and small PC users? Now I will explain it for you.
Nv1m.2nvme SSD is the fourth product in Kingston m.2nvme hardware array. Its official nominal read / write speeds are 2100mb / s and 1700mb / s respectively.
Kingston nv1m.2nvme SSD is 2280 long, which can be compatible with most PC desktop, notebook and even NUC devices. Three versions of 500GB, 1TB and 2TB are provided, only user can choose; The larger the capacity is, the higher the endurance of the total number of written bytes is. The endurance of 2TB total number of written bytes is 480tbw.
The nv1m.2nvme solid-state disk for testing is a 2TB capacity version, which adopts a single-sided design, including the main control, particles, and circuits, which are all on the front of PCB and covered by stickers. And the back is quite clean, you can see the detailed wiring of the circuit.
The stickers are still full of Kingston style, with strong product recognition.
The m-key pin can be seen at the end of SSD, which supports nvme. At the same time, pay attention to the version capacity.
Tear off the sticker on the surface of nv1m.2nvme solid-state drive, the dramless solution of Phison family. In my impression, Kingston’s consumer grade m.2nvme SSD is the first time to adopt no cache solution.
The main controller is ps5013-e13-31, a single core 32bit microcontroller with tsmc28nm process, which supports pciegen3x4nvme1.3 specification, 3dtlc and 3dqlc particles, and supports up to 4-channel 16ce, that is, up to 2TB capacity of four 4ce particles in a single PCB.
NAND particles are self styled by Kingston, although we are not sure of the detailed specifications of the particles from the official channels. But using Flash software, we can know the particle parameters: this particle is Intel 64 layer 3dqlc particles, single capacity is 512gb.
The test platform is composed of Intel flagship i9-11900k processor, ASUS m13a, ASUS rogstrix rtx3090 and Zhiqi ddr4-4000c15. The main disk is Samsung 970evoplus and the test disk is Kingston nv1m.2nvme solid state disk.
Crystal disk info 8.9.0 is a tool for detecting the health status of hard disk. In the software, we can see that the firmware version of Kingston nv1m.2nvme solid state disk is edfk5n09, the transmission mode is pcie3.0x4 channel, supports nvme1.3 protocol standard, and is equipped with trim and volatilewritecache functions.
Kingston official gives nv1m.2nvme SSD nominal read / write speeds of 2100mb / s and 1700mb / s respectively. Using crystal disk mark 6.0 to test the solid state disk, the reading speed of seqq32t1 in 1GB file test is 2105.2mb/s, and the writing speed is 1901.0mb/s; In the 16GB file test, the reading speed of seqq32t1 is 2118.8mb/s, and the writing speed is 1635.4mb/s; This performance is even better than the official nominal value.
In the asssd test, Kingston nv1m.2nvme SSD performs quite well. In terms of 4KB file access, the random read IOPs value is 16437, and the random write IOPs value is 63911. The IOPs values of 64t multithreading reading / writing 4KB files are 412978 and 334352, with a total score of 4520.
Using hdtunepro software for slccache test, 200GB space is full, which also proves that the cache space of SSD is larger than 200g.
M13abois tool cleans the secureerase of nv1m.2nvme solid-state disk. In raw mode, the disk writes to the full disk of txbench to test slccache. After 508gb of space is written, the speed decreases slowly with the continuous data writing, which is a bit similar to the full disk SLC.
Temperature performance, nv1m.2nvme SSD after a long time of testing, the highest temperature is 46 degrees. Of course, this test is carried out with the heat dissipation vest on the motherboard, but even so, the temperature performance of the solid-state disk is relatively good, which can ensure long-time high-speed transmission.
Conclusion: the entry-level m.2nvme SSD with high cost performance
In this test, the performance of Kingston nv1m.2nvme SSD is fully in line with the product positioning of entry-level m.2nvme SSD. Group connected dramless solution + self encapsulated Intel particles guarantee both quality and service life; At the same time, because of dramless, the cost of the whole SSD is well controlled, so that the price of 2tb1499 yuan can be made; And with the heat dissipation vest on the motherboard, its temperature control is quite outstanding, so that the SSD can maintain high-speed read-write performance.
Finally, I think everyone has a different pursuit, players always like high sex price, but they need to pay more price; The entry-level m.2nvme SSD products like Kingston nv1m.2nvme SSD are very suitable for consumers who pursue cost performance, especially notebook or PC users to upgrade, experience the performance advantages brought by m.2nvme SSD, and put the money saved into other devices with rising prices. Why not?
