It has been nearly a year and a half since Samsung officially launched 970 Evo plus (January 22, 2019), during which new products of large and small manufacturers frequently appear.

Even if you can see that the original non-storage field manufacturers also join in, so that the SSD of this field of the instant more than a bit of gunpowder.

Xiaobian's Samsung 970 Evo plus has been in service for more than half a year. It is usually used to make game boards and refit mobile hard disks. Today, I will give it a comprehensive evaluation and tell you how the SSD experience it brings to me has changed.

970EVO Plus: can still be our flagship

From the specification list, 970 Evo plus still has absolute strength in the current PCIe 3.0 solid state:

With Samsung Phoenix main control, 96 layer stack TLC flash memory, 3300mb / s write speed and 3500mb / s read speed, the random read-write speed also has a considerable increase compared with the previous generation of products.

For warranty, Samsung uses a term warranty and TBW warranty, the product base warranty for 5 years, write more than the amount will also lose warranty.

My 1 TB version is 600 TBW,, as usual, after 5 years of warranty TBW not necessarily for me.

The standard 2280 size, m.2 interface, in addition to desktops, is also suitable for many new notebooks. Its small size and light weight are also one of the biggest advantages of m.2 SSD at present.

PCB board is designed on one side, there is no original at all on the back, only stickers, which are all kinds of international standard certification of SSD.

The whole SSD is almost all Samsung's own parts, the main control is Samsung Phoenix chip, the particles and cache are also their own things, which is also the place where Samsung solid-state is worth taking out to show muscle.

However, the hard disk is not equipped with heat sink, Samsung should not ignore the problem of heat generation, but in my previous experience, I can clearly feel the heat generated by the hard disk.

Samsung's own particles, according to the specifications, that is, two 512gb particles make up 1TB capacity.

Performance test:

CrystalDiskInfo information identification:

Through the crystal diskinfo software, you can roughly understand the operation status of the SSD, and you can see that the hard disk has a lot of read and write data, but for 600tbw, 6T writing is a fur.

There are 451 times of power on, but the power on time is only 291 hours, because I use it as a mobile hard disk and often unplug it.

The hard drive goes PCIe 3.0x 4 channel, NVMe 1.3 standard. A temperature of 45 SSD 10 minutes after standby

As SSD benchmark test:

AS SSD test will be combined with CPU performance score, so no matter how measured, the speed will be a little lower than the official nominal and actual use of the normal phenomenon.

So let's focus on the performance of 4K random read-write IOPs, an important performance indicator of SSD.

AS SSD test ,970 EVO Plus 4 K QD64 in 1 file test482403 IOPs were randomly read and 656075 IOPs were randomly written;

In the test of 10G file, under 4K qd64The random read is 445934 IOPs, and the random write is 481095 IOPs.

In terms of comprehensive speed comparison, 970 Evo plus is 35% faster than Konka e5000 1TB SSD which also uses Samsung particles as previously evaluated.

CrystalDiskMark test:

Crystal disk mark is the original disk reading and writing speed, which is more accurate.

The latest version of CDM has been able to choose 64GB file size for testing. In 1GB file testing, 970 Evo plusThe sequential read and write speeds reached 3570.51mb/s and 3354.79mb/s.

The performance of 4K random reading and writing is 51.41mb/s and 202.39mb/s. The performance of sequential reading and writing is good, but the performance of 4K reading and writing is a little weaker than that of the brand-new one

After the test size is increased to 64GB, 970 Evo plus'sThe sequential read speed remains the same, and the write speed drops to 2202.86mb/s,An estimated 64 GB of file samples were written out of the cache;

The performance of 4K random read and write is not decreased but increased. The read speed is increased to 57.3mb/s, and the write speed is maintained at the same speed.

Anvil`s Storage Utilities tests:

Anvil Storage Utilities it tests more items and displays more detailed information than previous tests.

三星970

In this test, 970 Evo plus achieved 3052.16mb/s, 2852.37mb/s in sequential reading and writing, 12847.35 IOPs and 48513.07 IOPs in random 4K reading and writing.

Atto disk benchmark test:

Atto disk benchmark calculates the continuous read-write speed of small files. There are 16 capacities from 16kb to 64MB.

三星970

The fastest reading interval was 32 KB-1MB, in ATTO Disk Benchmark testsThe read speed is maintained at about 3.33gb/s and the write speed is maintained at about 3.13gb/s.

HD tune Pro high volume pressure test:

三星970

In the HD tune file benchmark, we set a custom file write volume of 100GB, easily crossing the critical value of the cache, eliminating the acceleration of the product cache, and measuring the real performance of this product particle.

In the test, when the write data reaches about 43gb, the write speed of 970 Evo plus will drop from about 3000 MB / s to about 1500 MB / s, just half of which is in line with the current level of high-end TLC SSD.

Crystal Disk Info temperature monitoring, room temperature 25

However, until the completion of the file transmission did not occur speed drop problem, it seems that 970 EVO Plus temperature drop threshold set relatively high.

Folder copy test:

Folder Copy Test By copying a folder containing large and small files to test the speed of transmission stability and speed drop node, we use the game "Destiny 2" folder file copy into the test, this test file size about 89 GB..

In this copy test, the transmission speed fluctuation is relatively large, but the overall transmission speed is relatively fast.

In addition to a large number of small files at the end of the transmission speed plummeted for a while, the speed of the rest of the time is maintained at about 1.4gb/s, which is more suitable for the speed after the speed drop.

Summary:

三星970

Even though Samsung 970 Evo plus has been launched for a year and a half, it still has the strong performance that surpasses most SSDs on the market after it has been ravaged by Xiaobian for half a year.

Both play games and office have a very rapid response speed, which also reflects the performance of Samsung self-developed Phoenix master and self-developed particle reliability.

三星970

Speed and ease of use, in addition to the TLC SSD must drop speed problem, it is almost impeccable, high 4 K IOPS, high sequential reading and writing speed, whether used or transmitted data, the speed is very high.

But it's also a model

三星970

But as long as it is put into the computer for safe use, I believe you will not encounter this problem, and now many motherboards are pre-installed SSD heat sink, but also very good for it.
