Will solid state hard drive partition shorten the lifespan, will it affect the performance after full?

After getting the hard disk, the first partition is the normal operation in the past. In the mixed game of SSD + HDD, many SSD users with 500GB of content will not have a cold for the partition, especially some people have suggested that SSD cannot be partitioned, otherwise Will damage the life.

This theory is not without theoretical support, especially those who think that "SSD partition will shorten the life" believes that "after the SSD partition is equivalent to turning a large-capacity hard drive into a few small-capacity hard drives, the life is shorter. A 240GB SSD, if divided into two areas of 50GB C drive and 190GB D drive, in which C drive is installed and frequently used, the life will be shorter, and eventually the entire hard drive will be damaged when most of the D drive capacity is not used , So even partitions, the capacity of common partitions should be set as large as possible. "

For this theory that seems a little reasonable, Little Lion can explain to you that-for mechanical hard drives, if only data is written to drive C, drive D is completely idle. For SSD, it is completely different. The main control and firmware algorithm will dynamically map the capacity of C drive to the physical space of the full disk capacity. It seems that only the C drive is written to the surface. In fact, the entire disk is written, there is no only Using part of the flash memory accelerates the problem of overall damage.

In other words, there is no problem with the use of SSD partitions. Here, Little Lion recommends that you use 500GB of SSD with content, and divide it into two areas. After all, the system plus the necessary software will kill your 100GB hard disk space without paying attention. Too much and too little is really not necessary. It is better to wait for the SSD price to stabilize a little before buying one or upgrading to a large capacity.

 

"If the SSD is full, it will slow down, and advise users not to use the SSD when it is full. You need to reserve a certain amount of space, otherwise there will be a decline in solid-state performance." Combined with the old mobile phone in the hands of the little lion, It seems that this question is very reliable. Anyway, my phone is full of APPs or data, and the running speed will be down, but this can determine whether we should write the SSD too full?

This topic came from a fairly early research document, the research report puts it this way: "128G solid-state hard drive, when using half capacity and full capacity, the steady state read and write performance is 6 to 10 times worse .Why is there such a big gap? This is because the flash erase speed is much slower than writing, MLC takes 3 milliseconds, and TLC requires 4.5 milliseconds, which is more than 3 times slower than writing speed. For solid-state drives The fuller it is, the more difficult it is for the master to erase and move. When writing, the flash memory can be written one grid by one grid, but the erase can only be erased by a whole page, even if there is only one grid on a piece of paper. Control also had to copy this word onto other paper before erasing it. "

In fact, entry-level solid-state drives usually shrink their usable capacity, and reserve some space to prevent the SSD from being completely full. This is why the capacity of many SSDs on the market is 240G or 480G instead of 256G and 512G. Mid-range and high-end SSDs will be additionally equipped with cache to reduce write amplification.

In other words, the manufacturer basically considered the problem of "full" for us, and made mandatory changes, we don't need to worry about what is directly happy to use.
