Where is Plus?
This time we are trying out the M.2 2280 version of EVO Plus 250GB, which has a total of 4 versions, namely 2TB, 1TB, 500GB and 250GB. The comparison with the official specifications of 970 EVO and 970 EVO Plus is as follows:
Compared with the 970 EVO, we can see that the 970 EVO PLUS is still controlled by Samsung Phoenix, and the flash memory has been upgraded from the previous 64-layer stack to the 9x layer stack.
The continuous write speed is slightly improved, reaching 3300 MB gamble, and the random read and write speed is also improved by a large proportion. The overall user experience will be better, and the response is faster in the actual scene.
The total number of bytes written is the same as that of 970 EVO, and everyone is 150TB (250GB version), that is, it is officially promised that the maximum total number of bytes written is 150TB.
The style of the box is the same as the usual Samsung SSD, we get the 250GB version, and the capacity is written on the top of the box.
Inside is the SSD ontology and instructions.
Standard 2280 size, M.2 interface, in addition to desktops, but also suitable for many new notebooks, small size, suitable for lightweight books is also one of the biggest advantages of M.2 SSD.
Samsung 970 EVO Plus PCB board uses one-sided design, there is no original on the back, only stickers, the stickers are certified by various international standards of SSD.
Anyway, the appearance is very "Samsung", sticker style, PCB color matching is so. Next, open the sticker to see the particles and the main control.
The main control part
With a little heat with a hot air gun, the sticker can be taken off smoothly, and the main control of SSD is all designed on this side of the PCB board.
The main control is Samsung PHOENIX chip, and the information of this master can not be found on the Internet. Samsung's own master control is generally for its own use, rarely sold to third-party SSD brands, and the performance has always been very good, at least at the high-end level. So whether it is good or not, check it out with a test later.
The use of Samsung's own particles, 512MB's LPDDR4 particles, daily use is also enough, can effectively improve.Random read / write speed..
Samsung's 96-layer V-NAND is also used for flash memory particles.Stack technology, using cascading stack technology to increase the volume density of particles is actually the most reliable method.
Let's move on to the actual test to fully test the performance of the 970 EVO Plus SSD of this 250GB version.
A brief introduction to the platform
In order not to cause the test bottleneck, we use the current top performance hardware as the test platform, including i9Mu9900K, Z390 motherboard and four 3200MHz frequency dual-channel memory.
Most of the SSD test projects are new versions of test software, including CDM 6. 0, AS SSD Benchmark 2. 0, Anvil Pro, etc., as follows.
.CrystalDiskInfo Information Identification:
Through the CrystalDiskInfo software, we can get a general idea of the operation of the SSD. For example, we can see that the Samsung 970 Evo Plus 250GB firmware version we tested this time is 1B2QEXM7, which supports the S.M.A.R.T function and the brand-new NVM Express1.3 standard. New disk, read and write capacity is still 0.
. CrystalDiskMark Test:
In the CrystalDiskMark test, this Samsung 970 Evo Plus 250GB SSD. In the test of 1G file, the sequential read and write speed is as high as 3543.5 MB/s, 2387MB/s.4K random read and write performance, which can reach 45.66MB/s, 140.6MB, which is an excellent level of random speed in SSD. Officially, sequential write speed is 53% higher than that of 970 EVO, which is a very big improvement, and there is a good experience improvement for instant operation.
. AS SSD Benchmark Test:
In the AS SSD test, the Samsung 970 Evo Plus 250GB SSD continues to read and write as fast as 2904.91MB/s and 2259.12MB/s in the 1G file test.
. ATTO Disk Benchmark performance Test:
When using ATTO to test the read and write speed of SSD under different sizes of data test packages, we can see that Samsung 970 Evo Plus 250GB SSD has a maximum read speed of 3.18GB Evo Plus 250GB SSD and a maximum write speed of 2.22GB/s. By the time the data size is 1MB, the speed tends to stabilize and has remained at its peak ever since.
Nowadays, the performance of M.2 hard drive is getting stronger and stronger, but along with the performance growth is heating. It has been experienced that the temperature of Samsung 970 EVO Plus hard drive is only 77 °C under high load, which is a significant improvement compared to 970 EVO (full load 95 ℃). Moreover, at this time, the performance is also good, the test results are normal, it seems that Samsung's main control has been optimized for high temperature.
The theoretical test of Samsung 970 EVO Plus 250GB version has the highest read and write speeds of 3.4GB/s and 2.4GB Universe, which is considered in the market at present.Very high speed.After all, the reading has almost reached the peak of the PCIe 3.0 × 4M.2 interface, and no matter how fast it is, it won't be much faster than MB/s.
Going back to the upgrade of Plus, there are just a few points: 1V-NAND flash memory has been upgraded to 9x layer stack, compared with 64 layers in the previous generation. 2 the sequential write speed has been greatly improved, with an average increase of 53% over the previous generation, mainly due to the performance of cache and master.
The 970 EVO Plus has been listed in China recently, and its price is basically the same as that of the 970 EVO. Based on the fact that the tested read and write speed and full load temperature are better than 970 EVO, we will recommend the 970 EVO Plus with better performance.
