SSD slow down too worried that you are not too full
Many small partners know SSD deceleration after prolonged use is often a problem, especially brand-name products is inevitable. It may reflect that after he bought the SSD reliable brand, quality is not low, but bought not long, cool-cool full of data, significantly reducing write speed flew some little friends, this is how it happened? Xiao Bian chat this thing right.
First, in fact, this problem is not a flash in the pan or a brand, but because the data is too full. Specifically, it is the flash memory erase process related to the. Unlike mechanical hard disk, records the charge data for the SSD, it is not directly over the old data when new data is written, but also a complete memory module is landed.
So when new data is written, if there is not enough number of blank memory modules, SSD will need to put some scattered old data recovery in the distribution of the various modules, organize and store together, then empty some complete storage module, these empty modules zero state. This process sounds very complex, requiring longer operating, move more data, of course, has caused a sharp decline in write speed.
Obviously, if the SSD plug too full, the write data when the blank module less available, the more likely this occurs, of course, the writing speed is decreased visible. So how to avoid this situation? First, of course, is not the SSD is full, if the system is frequent disk read and write, it is only about 1/2 of the space as well.
In addition, the time of purchase to prefer SSD with a large cache of these caches in capacity is too full, we need to organize your data when you can as a buffer to speed up the processing speed; can temporarily store data to be written, waiting to get a flash memory module re-write the series after the operation, to reduce the waiting time.
In addition we use every day have to develop good habits, such as for infrequently used file timely cleanup to protect the SSD has enough space; open and CG TRIM function, so he often SSD to clean up, to reduce the fragmentation of data, freeing up more blank memory module.
