Quote from: Nithin Sastry Tellapuri on December 10, 2022, 05:23:19can you please confirm if its Intel evo certified? The ads show that it is whereas the website doesn't say the same. Does this have all the Intel evo features?
How's the boot and shutdown timing? Is it below 10 seconds? This is something that you should include in your reviews.
They never even check the real bandwidth of the ports. And for example, in most laptops, where an HDMI 2.1 port is allegedly declared, often an outdated 2.0b or at best 24Gb/s is hidden under this nameplate 2.1, i.e. 1/2 of a full port 2.1. Exactly the same as with Display Port 2.0. And all USB ports also need to be checked for compliance with the standard. Including maximum current.
A complete and thorough study requires a powerful laboratory with a lot of equipment worth money. Obviously, you can keep such no more than 2-3 for small company. With constant updating and calibration of high-precision testing equipment. And there you need to bring all models of laptops purchased in random order. And even this is not enough - each model needs to be rechecked once every 1-2 quarters, because all manufacturers defame the quality of the goods, deliberately supplying in the first batches (when there are a lot of first reviews that everyone is guided by) the best quality component goods. And then they drastically lower the quality or deliberately dilute the batches with components of several times worse quality in different proportions, thus ensuring the minimum required margin level in the batches, because if you sell only high-quality components in goods, this margin level is not provided.
The simplest example is an SSD. At the beginning, there are expensive components, a controller, nand chips, and then, in the next batches, the controller is installed much cheaper, with a lower clock frequency and cheaper nand chips in worst grade by the number of cycles and self-discharge rate, plus more defects, also operating at a lower frequency. For example, the "twin" series from HP and A-Data - 950Ex and 8200. At the beginning of sales, the sustained write speed in the first batches outside the SLC cache was more than 500Mb/s, now it has dropped to ~250, because everything is cheaper, but not a word is fraudulently said to the consumer about this in datasheet or a clear change in the product code (and most often such business behavior is even punishable in most countries of the world). As a result, naive consumers read reviews of SSD from the first batches, where everything is made on much higher-performance components, and in retail lots with much cheaper and slower components are already sold everywhere in subsequent batches, after 1-2 quarters. This is a disgusting tactic of modern business, but it is who is used without a twinge of conscience - everywhere.
In smartphones, the same Chinese manufacturers, including Xiaomi, are constantly engaged in such forgery – changing class of component the filling to a cheaper one in 85-90% of batches, leaving about 10-15% of quality in batches, in order to ensure the necessary level of profit, otherwise they will just crash into the pipe.
This leads to the need to check several random copies in batches at once and new batches at least once every 2 quarters. And this site and all the others check at best ONE copy ONE time for the entire time of its production. What is the point of such reviews for buyers if they do not immediately buy the product in the first batches? Now do you understand why some of the more experienced buyers, just like in some totalitarian country like the USSR, line up in the West to buy the first batches of goods? They already know that subsequent batches are definitely not worth the money in terms of quality. Some flaws can indeed be corrected in subsequent batches, but the overall quality inevitably falls quietly for buyers - because otherwise the planned margin level for the manufacturer cannot be achieved.
And who is the rich Pinocchio who, without the help of manufacturers and society, will do this reviews with high quality check all features of goods and with the necessary frequency of rechecking batches to keep the reviews up to date (and on condition that you trust their author and company)?
