IT Home News on November 3 Recently, some users have reported that some batches of solid state drives for Lenovo Xiaoxin Pro 13 have been replaced by Samsung PM981A Yealink . Many users who bought the machine said that the solid state drive of the machine they got was not good. The model number has changed from Wei to Huili and Samsung to Yilian, so there have been returns.
In response to the above situation, Lenovo officials have just issued a statement in response to the matter. The following is the full text of Lenovo's response:
Announcement on Xiaoxin Pro 13 solid state drive (SSD) configuration issues
Due to the supply strategy of important component resources, all product components, including SSD, are supplied from multiple sources. The SSDs equipped with Xiaoxin Pro 13 (all versions) this time are all mixed materials, including Samsung PM981a, Yilian AH530, Western Digital SSD. The above three SSDs all comply with the NVMe protocol PCIe x4 technical specifications. The overall performance of the machine has been tested before the SSD leaves the factory and meets Lenovo's factory parameter requirements. The quality assurance is also the same, and there are no warranty policies for SSDs from different manufacturers. There is no difference, please feel free to use it. Since Western Digital SSD currently does not support the real-time online function (always on always connected), it is not imported in Xiaoxin Pro13. The writing capacity standard of
SSD is endurance 512G 150TBW, 1T 300TBW. TBW refers to 1024GB of Write, which means W refers to the write volume. Now both Samsung, UMIS and other SSDs have reached this standard.
In layman's terms, the life of SSD is expressed by the amount of writing, because the amount of writing can be obtained through actual testing.
From the perspective of user usage, the average user writes only a few gigabytes per day. When setting the spec, based on the daily writing volume of 50G, 512G, 150TBW can be used for approximately 8.4 years, and 1T, 300TBW can be used for approximately 16.8 years. Mixing materials for important components of
is a common and necessary practice in the industry. For example, the iPhone A9 processor has different versions. During production, SSDs are "used for what they are used for", and the brand and model used have nothing to do with the batch configuration. We have not publicized that the Pro 13 uses a single SSD material. When showing the SSD in the official unboxing review, we also specified that the SSD shown on the screen is the configuration of "this machine". The first batch of media evaluation machines are the same batch of retail prototypes, and the materials used are Same thing, I hope you understand, we will also learn from the lesson and inform you in advance in a more detailed manner next time.
If you want to know more about the performance level of Yilian AH530:
Theoretical performance of Yilian AH530:
The above are the internal test results provided by our company's research and development. Although Yilian's continuous writing performance is stronger than Intel 760p and weaker than PM981a, 4K The reading and writing level of small files is very good.
We also tested the latest version 7.0.0 of CrystalDiskMark, a common SSD software. Samsung PM981a still has obvious advantages in continuous writing, but it is not as exaggerated as some online rumors. At the same time, Yilian AH530 is the most important for daily use of SSD. It is not inferior to PM981a in reading and writing small files.
It is worth mentioning that all SSD test scenarios need to ensure that the configuration of the test machine is exactly the same, the software environment during testing is the same, and the background running software environment during testing is the same.
Yilian AH530 actual experience:
We have measured several scenarios:
Yilian AH530 is slightly slower than PM981a in booting to the desktop and copying files;
entering the desktop is faster than 760p and Micron 2200;
PS opens PSD as fast as PM981a Very similar, weaker than 760p and better than Micron 2200;
Assassin's Creed: Odyssey is not sensitive to SSD when entering the game;
CS:GO is relatively fast when entering the game. It is slightly slower than 1TB Intel 760p and stronger than PM981a and Micron. 2200.
At the same time, the memory controller of Yilian AH530 is the same as that of most mainstream SSDs. This time, the Yilian AH530 of Xiaoxin Pro 13 uses Phison ps5012-e12, Nanya DRAM, Memory Technology self-labeled Toshiba chip.
If you still have questions about the components and materials used in the Pro 13 you purchased, you can return it on the premise of complying with each platform's seven-day no-reason return requirement. Please consult each sales platform for specific return policies.
