1. Conventional mobile hard disks are likely to buy fakes, not to mention SSDs. One of my friends, Taobao, bought a mobile hard disk, but he couldn't see what it looked like and felt like. When he took it back and used it, he found that it was wrong. When he took it apart, he found that it was a U-disk and an iron hook to increase the weight inside...
it's suggested to go to a regular business to buy it, at least with a guarantee.

2. As long as it is placed in this SSD, no matter which partition, the startup speed should be faster. From the performance point of view, the advantage of solid-state disk is still great, that is, the price is too expensive
3. There are both reliable and unreliable. On the one hand, it depends on our own identification, and then it depends on ideas
take a good look at the seller's sales record review and choose the key points carefully.

4. Not recommended. The hardware on the computer, a power supply and a hard disk, are all perishable. On these two new hardware, we recommend a new one.
5. If you choose for me, you won't buy it. Kingston, Intel and Sandi are about 50 yuan expensive, so you can rest assured with them
6. The water is too deep
not recommended
unless you are an expert
besides, it's informative to deal with others
otherwise, forget it

7. What you said above is basically no problem. Recently, I have plans to buy SSD,
so, share what I know,
solve the problems one by one,
1, size, generally 64g, 128G, etc., depending on the budget,
generally speaking, I have to consider the interface, sata3.0 up to 600m / s, sata2.0 about 300m / s, sata2.0 up to 300m / s, sata3.0 up to 600m / s, sata2.0 up to 300m / s, sata2.0 up to 300m / s, sata2.0 up Msata (common notebook) is usually PCI-E, which is equivalent to 2.0 interface speed at most,
2, service life, SLC / MLC is the current common SSD technology,
SLC is better than MLC, s's 10W read / write life is longer than M's 1W read / write life,
but SLC is currently high cost, small capacity, low cost performance, so most of what you see are MLC
but that doesn't mean it's not rable.
for example (you can look at the network and extract from the network), a complete erasure of flash memory is called once P / e. the life of a 34nm flash chip is about 5000 times P / E, while that of a 25nm flash chip is about 3000 times P / E. Does it look shorter? Theoretically, it's true, but with the improvement of SSD Firmware algorithm, the main control chip will have intelligent allocation. For example, if the average space is used, a 60g solid-state hard disk, for example, and a 60g file is written as a P / E, ordinary users can use it normally. Even if they write 50g P / E every day and once a day, there will be 360 P / E and 3000 P / E in a year. How many years can they use it? I believe that you have updated several generations of computers in ten years, so the service life is not a big problem.
3. There is no big problem with the system, but the system after win7 and before XP has no support for SSD.
4. This 4K alignment is very important, otherwise the performance will be lost. I heard that it is 25% and it can be seen from the results of the test software The biggest advantage of SSD lies in 4K file processing speed, much better than mechanical hard disk,
5, learning from each other, high digital update efficiency, hard disk tardiness criticism finally to be solved, Congratulations, more technology, keep paying attention, long way to go, I will search up and down,
6, other questions can be asked, a hundred years do not answer Hand play ~
PS, click, the current price of Xbox's 128G MLC and sata3.0 interface is around 650, 64g three or four hundred bar, msata is a little more expensive, you buy things according to the budget

8. There are many things to pay attention to in the purchase of solid-state drives. It takes knowledge to buy any kind of things. To put it bluntly, don't aunts have to choose carefully when they buy eggs? I'd like to give you a brief introction here, which is expected to help you.
the advantage of SSD is that data can be read and written efficiently and can be recovered even if the physical damage is not serious. It is also a high-efficiency hard disk in different physical environments, but low capacity is its biggest disadvantage, so many people will buy mechanical hard disk to use with SSD, In terms of collocation, we should pay attention to control the capacity and carefully choose the cost performance ratio.
not all SSDs are easy to use. Simply buying SSDs should not only focus on the capacity, but also consider the quality, speed and interface. No matter how efficient the hard disk is, if you use a notebook, the interface can't be replaced at will, Therefore, we must be optimistic about the interface efficiency and the read-write efficiency of solid-state disk. The biggest advantage of solid-state disk is the efficiency. We can't waste it. For desktop computers, we should pay attention to the interface and solid-state disk. Generally speaking, the stat interface can meet the requirements of most people. It's just for reference. After all, the problem is too general, To be specific, each interface has its advantages and disadvantages. The problem is not the interface, just mention it briefly.
here, we also want to emphasize the choice of brands. Now the mainstream manufacturers of solid-state drives are Samsung, Intel and Procter. It is recommended that you buy Samsung, because Samsung's brand is very easy to use for indivials, and the instry has a good conscience, However, if you pay attention to hard disk life and data security, and push Intel and Proctor, you will have a good reputation. However, some people say that there are some defects in its procts, and they have never tried them in person, but the problems of poor after-sales and high price are distressing.
as for capacity, you can see 128G solid-state disk and 128G mechanical disk are two concepts! Solid state disks need to be partitioned into some unused areas. In order to extend their service life, generally speaking, to a certain extent, the more space they need to be partitioned out, the better. These are for the people who install the system. Unless you want to install the system yourself, I don't say so, but you must pay attention not to buy small ones, It's easy that the capacity is not enough (I can only use 64g, 52g, I've already cried)
so the specific suggestions are basically like this. I picked a part and said that it should be enough for you. Anyway, you can ask questions. I'm not very good at answering general questions. In short, I think about collocation, interface, brand and capacity.
I suddenly thought about flash memory, Toshiba, as one of the world's largest manufacturers of flash memory granules, has a very high quality of procts, but it's not interested in civil SSDs... I mentioned Samsung before. Its flash memory granules are of very high quality. Some people are black because of the price, which can be said to be expensive. In short, we recommend TLC granules, The average write life of 500-100 times is enough for you to use, because only one complete write can be regarded as a consumption of life. For example, the capacity of your disk is 60g, and every 60g you use (all hard disks are counted, such as delete, write, download, etc.) is one time, which is enough for you to use for many years. With the development speed of science and technology, when your SSD breaks down, People don't know what to store data with

9. According to your current economic level and demand, ordinary people should not buy it first
comparison of advantages and disadvantages between traditional hard disk and solid-state hard disk
1. Shockproof and fall resistance: the current traditional hard disk is disk type, and the data is stored in the disk sector. SSD is made of flash memory particles (i.e. current memory, MP3, U disk and other storage media), so there are no mechanical parts in SSD, which will not affect the normal use even in the case of high-speed movement or even with overturning and tilting, and minimize the possibility of data loss in the event of collision and shock. Compared with traditional hard disk, solid state hard disk has absolute advantage
2. Data storage speed: judging from the evaluation data, the performance of SSD is more than 2 times higher than that of traditional hard disk
3. Power consumption: the power consumption of SSD is better than that of traditional hard disk
4. Weight: SSD is lighter in weight, 20-30g lighter than conventional 1.8in hard disk
5. Noise: e to the fact that solid-state hard disk has no mechanical parts, i.e. flash memory chip, it has the characteristics of small heat generation and fast heat dissipation, and it has no mechanical motor and fan, so the working noise value is 0 dB, while the traditional hard disk is much inferior
6. Price: at present, 80g
Intel SSD is on the market, and the price is about 4000 yuan. And this price is enough to buy a few traditional hard disks with 1TB capacity
7. Capacity: at present, the maximum capacity of SSD is only 256g, which is quite different from that of traditional hard disk
it can be seen that although the performance of SSD is greatly improved, there are also many inherent disadvantages. Especially in today's era of dissatisfaction with the demand for large capacity hard disk, the capacity of SSD is a fatal injury, and the service life of SSD is very poor, which is a nightmare for precious data.
