I. Introduction
Now that the solid state of PCIe 4.0 is becoming more and more mainstream, not only the price has become mainstream, but also the awareness of this PCIe 4.0 solid state has gradually become mainstream.
Now come to find the mushroom installed small partners, all know to pcIe 4.0 solid state, and roll call to Samsung's PM980 Pro this piece. To be honest, I didn't use pcIe 4.0 solid state myself, haha. Well, without further ado, I know, I'm poor.
Since you want to go to Samsung's 980 Pro, you have to mention his twin brother, PM9A1 this solid state. The same configuration and materials, the price is directly cut, do you want to use it? Of course, PM9A1 this solid state is more awkward in terms of warranty, basically only store protection, must choose a reliable store.
Second, Samsung PM9A1 solid state 1TB out of the box
▼ Mushroom selection of this shop is quite reliable, the overall price is OK, that is, the accessories did not send anything, the heat dissipation iron pieces were not sent. However, the store is reliable, and the warranty is assured.
▼ The solid state is packed with a plastic shell, and the protective effect is OK.
Third, Samsung PM9A1 solid state 1TB appearance
▼ The appearance of the SSD is still very familiar, black PCB, white label, 2280 length.
▼ The back of the SSD is also a black PCB, and the words Samsung SSD are written in the upper left corner.
▼ Main control part, Samsung's self-developed Elpis master control, ARM architecture, main control silk screen printing S4LV003.
▼ Cache part, LPDDR4 cache granule with a capacity of 1GB, frequency 4266, single.
▼ There is a pure black IC next to the cache, which should be a power supply chip, and the surrounding is densely packed with capacitors.
▼ Flash memory is Samsung's own 512G particles, two, commonly composed of 1TB of capacity. Samsung's solid state is still quite good, the main control, cache, flash memory are their own, a variety of performance to play, hardware compatibility is naturally the best.
Fourth, Samsung PM9A1 solid state 1TB installation
▼ The installation of the SSD is still very simple, here the mushroom is first installed into their own computer to test.
▼ Solid state specification is 2280, daily compatibility performance is good, basically there are M2 slots of the motherboard can be installed.
▼Here, the solid state is directly inserted into the M2 slot closest to the CPU, and the CPU is directly connected to ensure performance.
▼ M2 slot of MSI Z690 Blade Ti motherboard adopts a quick release design, there is a black plastic piece responsible for fixing the solid state, daily installation is convenient.
▼ In addition, the M2 slot of this motherboard is covered with metal heatsink to ensure the stability of M2 solid-state operation.
▼ Install the graphics card, Sotecet's RTX3070Ti Apocalypse OC, the material and stability of this card is still quite good.
▼ Daily default horizontal installation, the tail of the graphics card is installed with a graphics card bracket to ensure the support of the tail of the graphics card, to prevent the graphics card from bending.
▼ The whole machine effect is still quite good, the chassis is Antic DF700 Flux.
▼ Water cooling is MSI's Frost K360 all-in-one water cooling, the water cooling head comes with a screen, which can display a lot of information.
▼ The motherboard is MSI's Z690 Blade Ti motherboard, and the IO trim part of the motherboard has a beautiful metal heatsink, which is very good.
▼ The power supply is MSI's MPG A850GF power supply, gold medal full module, 10 years warranty, or very good.
▼ The details of the power supply are good, and the 8Pin auxiliary power supply line of the graphics card is designed with a single 8Pin, which will be more stable when the load is high, and the single line load is lower.
▼ Boot, light up at once, the whole machine effect is still very beautiful.
▼ MSI's Frost K360 water-cooled cold head screen is still very interesting, can directly display the temperature of the CPU, very practical. The cold drain fan supports ARGB lighting effects, which is very beautiful.
▼ MSI Z690 Blade Ti Motherboard's IO trim on the MSI Dragon Shield LOGO supports ARGB lighting effects, which looks very beautiful.
▼ The memory is Zadak's SPARK, and the light strip at the top of the memory is a whole design, the color transition is uniform, and the soft light effect is good.
▼There is also a multi-segment RGB light strip on the side of the memory, which looks very good and has a sense of design.
▼ The front and sides of the graphics card have ARGB lighting effects, and this RTX3070Ti Apocalypse OC graphics card of Sotai is very good in horizontal and vertical mounting.
▼ The chassis is Antick's DF700 Flux, the front of this chassis has a large area of metal punching mesh, the air intake area is huge, and the heat dissipation effect is first-class.
▼ And this metal punching mesh also has a curved shape, with the internal ARGB fan, the overall effect is quite good.
5. Samsung PM9A1 solid state 1TB test
▼ The whole machine configuration list, the processor is 12700K, the motherboard is MSI's Z690 Blade Ti motherboard, the memory is Zadak's SPARK, and the graphics card is Sotai's RTX3070Ti Apocalypse OC.
▼ Simple running points, the whole machine score 189W, processor 84W, graphics card 60.3W, the performance is very good.
▼ New SSD, the first time on the computer need to initialize.
▼ Samsung this solid state, the nominal capacity of 1TB, the actual usable capacity of 953GB, not bad.
▼ A simple look at the parameters, the solid state is the latest 7401Q, the interface is PCIe4.0 x 4, support dynamic write Cache technology. In the case of daily standby, the temperature of the solid state is about 41 ° C, with the original metal heat sink of the motherboard.
▼Simple to run a test with AS SSD, the cis-read speed is 5153MB/s, the write is 3851MB/s, and the 4K performance is 87MB/s and the write is 238MB/s. Sequential read and write speed feel more ordinary, and 4K performance is not bad, especially 4K write performance. In addition, the response time of the storage particles is also quite good, very low, less than 0.02ms.
▼ The test file was increased from 1GB to 10GB, the overall performance of the SSD was almost exactly the same, the performance fluctuation was super small, and the score was also increased by 50 points, which was outrageous.
▼ Switch to the DiskMark test, the test file size is 1GB, the sequential read speed is 6400MB/s, and the write speed is 4998MB/s. In terms of 4K performance, the write read is 91MB/s and the read is 265MB/s, and the performance is good.
▼ The test file is increased from 1GB to 8GB, the sequential reading performance is slightly reduced, and the other performance remains basically unchanged.
▼ Then, run a continuous read and write 200GB test, SLC Cache is around 115GB, sequential write speed will be reduced, down to 1800MB/s. The reading curve feels a little bit sinister, and the overall feeling is OK.
▼ In terms of heat dissipation, with the original heatsink of the motherboard, the maximum temperature of the SSD is about 53 ° C in the case of continuous testing, and the overall is not bad.
6. Summary
Samsung this PM9A1 solid state as a whole is still very good, the cost performance is very high, and Samsung's top consumer grade PCIe4.0 solid state a material, but the price is only half of the former, very good. For those who are looking for performance, stability and cost-effectiveness, there is a choice. But there is a point to note, the warranty will be slightly troublesome, try to choose a reliable channel.
Aside from the warranty, the rest is almost all about the pros. The performance is very good, mainstream above PCIe 4.0 performance. Sequential reading and writing performance is also good, and the performance of 4K will be more prominent.
However, the heat of the solid-state drive is not small, with the motherboard original thick metal heatsink, heat conduction pad, continue to run the test, its temperature is still more than 50 ° C.
Thank you!
