With the flash memory prices, SSD prices continue to rise, naturally, more and more manufacturers are targeting the fat piece of SSD.
Former GALAXY, Rainbow, the current atrophy, Xiaodong look at these graphics manufacturers into the field of SSD production, can not help and most consumers have the same doubts, these all-powerful in the video card brand, the production of SSD can Just as reliable as the graphics cards they produce?
Today, Xiao Dong fortunate enough to get a Geng XM240 PCIe3.0 SSD, let us explore it to see how the performance of this product.
Appearance
2016 Ascendas released a series of SATA SDD test water solid state hard drive, the next step is naturally released popular M.2 NVMe SSD products, positioning high-performance 'X' series SSD is also the birth of its own naturally.
Gengsheng XM240 PCIe3.0 As the first M.2 NVMe SSD in the 'X' series, his packaging showed a strong family signal, a big letter 'X' LOGO, coupled with the spread of the red-orange color, Aggressive, I believe this packaging design elements will continue to 'X' series of other products, such as his 120GB version XM120.
After the product is taken out, the most striking is its heat sink.From the appearance of Gower XM240 PCIe3.0 and most other products is different from the use of semi-wrapped heat sink, heat sink surface using the drawing process, it seems Or a little handicraft feeling, engraved above the iconic LOGO.
The role of heat sink M.2 SSD is very important, we all know that M.2 SSD is also a big heat, if the host overheating the SSD will slow down or even speed, we can see behind the heat sink cooling effect is not Very awesome.
Behind the product you can see it's warranty stickers, product s / n code above, you can go to the official website to identify the authenticity, next to the two-dimensional code, scan the official website to verify the authenticity of the page. Product warranty policy is 3 years replacement , Is also the warranty policy commonly used by SSD manufacturers.
The size of the product is 22 * 80mm, gold fingers clearly see M Key and B Key (that is, there are two gaps), you know this is a PCIe X 2-channel SSD, consistent with the official propaganda, the theoretical bandwidth of 16Gbps.
On the other hand, if the SSD has only M Key (the cheek has only the gap below), it is taking a higher performance PCIe X 4 lane SSD with twice the theoretical bandwidth and, of course, higher prices.
The official claims that the SSD has a continuous read and write capability of 1600 / 800MB / s and 4K read / write capability of 35 / 125MB / s, which is at the top of the PCIe X 2 SSD.
According to the manufacturer's data, the main controller uses a group PS5008-E8. The main controller uses PCI-E 3.0x2 channel NVMe SSD controller to position the entry level, but the interface bandwidth is still much higher than that of the SATA controller. The main controller Released in the performance test performance is also very stable than the Intel 600p ECG curve performance is much better.
Official claimed that this master up to 1600/1300 MB / s read and write speeds, in general, this control in terms of performance and price to find a better balance, but also the future of most entry-level NVMe SSD preferred master.
Official data show that the particles are Toshiba's 64-layer stack 3D TLC flash memory particles produced by manufacturers, the quality is still trustworthy.
testing platform
Test Platform Description: The test platform uses the mainstream consumer-level platform Z270 + i7 7700K, the system disk Micron MX300 525GB SATA solid state drive, from the disk to Gengsheng XM240.
SSD parameters:
summary: Because of small winter body in Guangzhou, when measured at room temperature about 22 °, we can see that this SSD temperature control is fairly good.
CrystalDiskMark test:
Test Summary:
In the CDM test, Gengsheng XM240 PCIe3.0 M.2 240GB solid state hard drive the fastest sustained read and write speed of 1600.6MB / s, 906.1MB / s. The measured results better than the official declared slightly better, in 4K random read Write performance, the fastest read and write speed of 41.5MB / s, 182.5MB / s, the performance is equally good.
However, this is the result of reading and writing smaller packets, which may be the credit for its cache. In order to get a more realistic performance of this product, we tested the larger data packet and continued reading and writing down to 1548.9MB / s , 871.1MB / s, respectively, in the 4K random read and write performance were 36.5MB / s, 183.8MB / s.
In general, the performance of the product in the write performance will be much better than the official publicity, performance and reading in terms of the average close to the official publicity, is a relatively good entry-level NVMe SSD, as a comparison, take the PCIe X 4 channel Intel 600p official propaganda highest continuous read and write capacity is only 1800 / 560MB / s.
AS SSD Benchmark Test:
Test Summary: In continuous reading and writing tests, Gengsheng XM240 PCIe3.0 M.2 240GB solid state drive the fastest sustained read and write speed of 1467.67MB / s, 826.22MB / s, worse than the CDM results.
Anvil`s Storage Utilities Test:
Test Summary: In the Anvil`s Storage Utilities test, the total score was 7612.83 points. By comparison, the SATA SSD score is about 4000 points and the top PCIe X4 SSD score is about 8500 points. It seems that this Gainward XM240 entry-level NVMe SSD Performance is much higher than the 'entry' level.
PCMark8 performance test:
Test Summary: Score 5035 points in PCMark 8 test, superior to ordinary SATA SSD several hundredths, with obvious advantages.
HD tune test:
Test Summary:
HD tune test can easily cross the threshold of SLC cache using up to 40GB test files, eliminating the product cache acceleration and calculating the true result of TLC tablets for this product.
However, this is of little significance to the average consumer because ordinary consumers have little chance of continuous read and write for a long time on a large scale, which is only of value to some users with specific needs, but most of these users purchase more expensive MLCs SLC products.
Of course, to maintain an objective and rigorous attitude, we tested the performance of the product when reading and writing on a large scale continuously. The results were as follows. The actual particle read and write speed was 616.2 / 317.1MB / s and performed well.
Control software EXPER TOOL:
summary: The Gainward XM240 SSD has a rather novel feature is supporting a SSD control software, real-time monitoring of SSD status, the measured actually found that the software is not perfect, and sometimes will not recognize the hard disk, this aspect of the need to work hard To repair.
to sum up
Gurung's 'X' series of SSDs, which blend the brand name of Goshen Storage with Gullah X Storage for the New Future, are generally better performing SSDs with top performance in entry-level NVMe SSDs, although the official The price has not yet been announced, but from the better pricing strategy of Gainward, the price of this SSD should be relatively inexpensive.
NVMe M.2 SSD has always been synonymous with high performance, but its high price has been to keep consumers away from it, in order to enhance the XM240 PCIe3.0 represented by PCIe X 2 SSD performance SATA SATA SSD far Throw away, but not much different from the PCIe X 4 SSD experience, reducing costs and price.
If Gainward XM240 pricing is very close to the people, it will not be universal 'NVM M.2 SSD' X 'factor? We'll see.
