What solid material is the cheapest and most cost effective on the market? 10

1.Southland pure coconut flour.

This was brought to me by a classmate who lived in Hainan when I was in school, although I can also accept sweeter drinks, but for the sake of health, I should focus on less sugar! A lot of coconut milk on the market is generally a little too sweet and greasy, this coconut powder is pure coconut powder, does not contain white sugar, and can be brewed with hot and cold water! The pouch packaging is also easy to carry!

And when you brew it, you can smell the full coconut fragrance, and the pure coconut flour in the south is really not sweet at all, it is that natural sweetness. Go to school and work in the morning with a cup of breakfast you like, and a lazy breakfast is complete! It's delicious and saves money, it's so fragrant!

2.Xiyun dietary cellulose protein peptides.

Dietary fiber is a low-energy substance and contributes to the maintenance of normal intestinal function. This is really a blessing for foodie friends! If you usually overeat and your digestion is not very good, you can try to take it with warm water before meals, or you can add it to hot soup, juice and other foods to drink!

The independent small package is also convenient to carry out at ordinary times, and it will not have a great taste when drinking, friends during fat loss can try this one!

3.Friends of the Valley magenta bean barley powder.

Red bean barley has the effect of dispelling dampness and edema. I also ate this when I was in school, and I used it as breakfast or when I was hungry at night and didn't dare to eat supper, I didn't dare to eat more supper because I was really afraid of being fat!! Serve a small bowl.

After drinking, there is also a feeling of satiety for two or three hours, and its sweetness** is xylitol, which is the most suitable for people during fat loss as breakfast. And I personally think it's still very fragrant, the powder is also very delicate, and it also contains diced strawberries, which is really delicious with it, Jimei hurry up!

If the cheapest cost-effective system in the solid material market is the largest, I feel that it should be the kind of gypsum board, they belong to the solid decoration materials, and they are very cheap.

Be sure to look for the cheapest, bulky solid substance, and it has to be "foam board". Large size, light weight, **the cheapest. Insulation and shockproof board for packaging.

The solid material is the cheapest, the most cost-effective, the largest volume on the market, and generally I think well, the largest volume and the cheapest on the market, I think it may be ice, that's the case.

Like these sour plum soups, if I say there is no such thing. They are all cost-effective, like the taste that Wei Chong and I came out of, and the taste of the sour plum soup we bought outside is the same finished product. load, but the underwear strap can be filled with multiple bottles, and the cost performance is very high.

The question is simple!

The scrap collection station went to buy waste foam materials, which are cheap, lightweight, and bulky!

Hope mine is helpful to you!

What kind of materials are needed cheaper, make it clear that others will know what you need, or you can look it up online or go to the store to see it.

Dense ones are fine.

For example, mercury (liquid).

Solid metals are generally denser than liquids.

The density of the liquid state is generally greater than that of the gaseous state (except in special cases, such as pressurization).

Metal materials have weak corrosion resistance, high cost and heavy weight.

Polymer materials have a short lifespan, extremely high cost, and are not resistant to oil and alkaline environments.

Ceramic materials are brittle, brittle and non-malleable.

The weight of metal materials is heavy, and the precision molding accuracy is difficult to control.

Polymer materials have problems with service life and strength.

Ceramic materials are brittle.

Metal materials have poor insulation, polymer materials have poor fire resistance and high temperature resistance, and ceramic materials have poor toughness.

Gold, silver, copper, and aluminum with higher purity have the conditions you mentioned, but because their comprehensive properties are poor, they are used less. Generally, our common ones are alloys. Gold, silver, copper, and aluminum, which are of high purity, can be easily rolled into extremely thin sheets.

There are many SSD brands on the market, but I mainly recommend the following brands.

1. Micron. Micron's SSD can choose 128G, which is completely sufficient for daily use. Micron has good stability, it will not freeze after a period of use, slow down and lack of space, and the performance of the system disk is also very good, it is a cost-effective solid state drive.

Second, Samsung. Samsung's SSDs aren't the stars, but their sheer quality stands up to consideration. Samsung's hardware level is good, and the materials used are very good, and it has also worked the stability of the hard disk, but the heat dissipation is slightly worse. But from the hard disk space to the speed of the hard disk system, it is worth buying.

3. Kingston.

Kingston is most famous for SD cards and USB flash drives, but SSDs are also OK, at the upper middle level, the biggest point is that it is cheap, and the space capacity is selective. However, after a long period of use, it may be a little worse in terms of stability.

In fact, it is not recommended to buy an SSD only by brand, according to personal needs, at least consider the capacity, chip, read and write speed, granularity and interface type. If you must recommend the brand, I mainly recommend the following two:

The first Intel 545s, this hard drive has a high praise rate in the market, and it can be said to be an excellent SSD, officially claiming to have a read speed of 500ms and a write speed of 500ms. The buyer's measured speed is also about 450M s read and write speed, and there are two interfaces to choose from: SATA3 and M2, using its own flash memory and core technology, which is perfect in all aspects.

Secondly, I recommend the Western Digital Green series, especially the 120GB version of the green disk. Produced by large factories, the performance is guaranteed, as long as it is purchased through regular channels, the warranty period is 3 years, and it is directly returned to the factory for repair. Of course, the most important thing is that it is cheap, the cost performance is absolutely high, and the reading speed can reach 300m s 400m s, which is completely sufficient.

However, if you are particularly concerned about the speed of reading and writing,You may have to be cautious,The biggest problem with the green disk is that the reading and writing speed is not good,Even LenovoSL700、Jintaike S300、KingstonA400Can't catch up。

I think that when choosing a solid-state drive (SSD), choose a slightly larger brand as much as possible (big brands are guaranteed, and electronic products are guaranteed), and you can't blindly pick only the biggest brand to buy. Personally, I recommend SanDisk as a solid-state state: SanDisk's Extreme 3D

First of all** is not high (Western Digital is about the same), in terms of the same level of solid-state, it is cheaper than Samsung, of course Samsung is very good is a good choice, SanDisk is another good choice in addition to this choice, and it is also very important to suit your own needs.

SanDisk is the world's largest manufacturer in terms of flash data memory card products, and he is the only one in the world that has the right to manufacture and sell all major flash memory card formats.

In terms of the size of solid-state memory, if you think that the 128G SSD is a bit small, 240G or 256G is a good choice, such as the 240G of SanDisk Extreme 3D, which is generally not higher than 400 yuan, and sometimes it is a lot more cost-effective.

Solid-state drives (SSDs) are now almost universal, and once you've used a computer with an SSD, you won't want to use one without one. The comparison of solid-state drives is very complicated, and the comparison between the various price points of various brands is also different, as far as the low-end is concerned (the mid-to-high-end, I have seen it in a report, such as the mid-to-high-end disk of Samsung SanDisk Micron, the after-sales repair rate is a few thousandths, or even a few tenths of a thousandth, and Kingston is up to three percent) The difference is not so big for brands like Samsung, Intel, SanDisk, etc.

Because there is an element of luck in buying electronic products, after-sales service is particularly critical when the quality difference is not obvious.

The first SSD from Samsung is launched. Samsung's hard drives are of very good quality, coupled with high performance and long lifespan, so there is no problem with using them for two to three years. The performance of the Samsung 860 Evo is comparable to that of the MLC.

It is a strong competitor to Western Digital and SanDisk.

Since its debut in 2014, the Samsung 850 EVO has been the go-to SSD recommendation, but after a long update, the company replaced the 850 with the Samsung 860 EVO in 2018.

The Samsung 860 EVO transmits data over PCI-E instead of the traditional SATA interface, but it is the fastest three-tier unit (TLC) SATA drive, and this drive has been tested to be the fastest data transfer drive. What's more, it solves the slow write performance that plagues many other SSDs that use TLC NAND chips. We replicated up to 80GB of data in a single test, and the EVO remained strong throughout the time, rather than staggering after exceeding its cache.

The cost of the new generation of hardware has risen slightly, but the Samsung 860 EVO still offers**, an attractive mix of performance and capacity that few SSDs can match, a long-term five-year warranty and Samsung's superb SSD software that makes it easy to install. And as an inch SATA drive, the Samsung 860 EVO should fit into most desktops or laptops without any problems.

At present, the well-known SSDs on the market are Micron, Samsung, Kingston, SanDisk, Rainbow, Shadow, etc., from my experience, I prefer the Samsung brand.

1. Micron: Maybe you are relatively unfamiliar with this brand, but you must be familiar with Kingston and SanDisk, these two senior players in the field of solid state drives, the wafers they use are provided by Micron, get the wafers and flash memory particles, and then assemble them by the production line and sell them under their own brands. Micron is a manufacturer that provides the flash part and has a large number of patented technologies, so there is no need to question the quality and performance of this brand's SSD, and many sellers are aiming for this name.

2. Samsung: This manufacturer is a giant, the product covers almost all aspects of our daily life, and Micron provides wafers for other SSD brands, of course, it also produces SSDs for external sales, with a super high cost performance has become the first choice for many assembly machine enthusiasts, large and small digital stores can see this brand of SSD**, quality and after-sales are quite guaranteed. I'm using Samsung's 120G SSD now, which has always been relatively stable, and it's very safe to use, and data security can be guaranteed.

3. Kingston: A veteran manufacturer specializing in the production of storage equipment from the United States, its products include U disks, memory modules, solid-state drives, etc., which have become frequent visitors to major computer cities with good cost performance and excellent quality, and one of the most commonly used brand accessories on the assembly machine.

4. SanDisk: After the rise of solid-state drives, SanDisk has turned into the industry from the previous USB flash drive production, and has done quite well, and has also occupied a certain market share and has a good reputation.

5. Rainbow, Shadow: Domestic assembly machine users will be no stranger to these two brands, these two have been deeply cultivated in the field of graphics cards for many years, and have accumulated rich research and development technology, and the installed utilization rate is very high, and they are deeply loved by users with excellent cost performance. The SSDs produced are also of reliable quality and cost-effective, which is worth recommending.

If you just use office office, there is no need to use an SSD, buy a 2TB, 3TB mechanical hard disk, and install a pure version of the system can also meet daily needs, and if it is other needs, I think it is necessary to install an SSD.

Solid-state driveA hard disk made of a solid-state electronic memory chip array is composed of a control unit and a storage unit (flash chip, DRAM chip). Compared with the laser head of the traditional mechanical hard disk to read the data on the disk disk, the speed increase is huge, the solution of the vast majority of users is to install the system disk (C disk) on the solid state disk, and then install a mechanical hard disk as a storage disk, which has a significant effect on the speed of system operation and program operation, and the work efficiency has also been greatly improved. At the same time, the flash memory particles of SSDs also solve the bottleneck caused by the barrel effect of slow hard disk speed and fast memory and CPU speed, so that the overall running speed of the computer has been improved a lot.

At present, there are two interfaces for SSD solid state drives, one is the traditional SATA, and the other is the interface, commonly known as.

Most motherboards already support interfaced SSDs, which are faster than traditional SATA interfaces (up to 700MB s read and 550MB s write). Socket3 can support PCI-E 4 interfaces, with a theoretical bandwidth of up to 4Gb S. The performance is more stable (mainly because the SATA interface requires two wires, one power cable and one data cable are prone to data loss after a sudden power failure, and the circuit board stability in this regard is excellent).

In terms of brand, try to choose first-line manufacturers, such as Samsung, Intel, Kingston, Toshiba and other brands, although it is more expensive than other manufacturers, but the quality of flash memory particles and motherboard control chipsets used by large manufacturers is far higher than that of second-tier brands, which can improve the performance of your solid state drive and further shorten the response time of hard disks.
