Make sure your operating system support TRIM command.

How to Enable Trim Support for Windows 8 and 7 But most of the users don’t know, not stretching OP area too thin makes you have lower write amplification, which converts to a higher performance during writes and longer endurance of the flash memory. The less amount of OP is in SSD, the more information users can store. the different amount depends on tradeoffs made between the capacity of total storage and profit in performance and endurance. This is called OP, and it plays an important role in every NADA SSD.Įach SSD has the amount of OP. In order to store this extra data which isn’t counted by OS, the flash controller needs some spare space.
Over-Provisioning (OP)īefore or during garbage collection, the copy of valid data is in 2 or more locations which are called write amplification. Besides, it takes Garbage Collection time to do its work, but when it is idle, your SSD will maintain its high level of performance. So you should make sure your computer doesn’t go to sleep when it’s idling. In this way, cleaning data in advance saves your time when you need to write data on the page again.Īttention: Garbage collection only available to your SSD, when it is idle. Because a trim command allows your operating system to find the marked pages before you need them and erase them clean. The easing takes time and it can cause serious delays which relies on how much data you want to delete. Then the final step is to erase the original whole block, leaving the space for new data to be written. The valid data must be wiped to make room for new data, so the flash memory controller copies the valid data of the block to a previously erased block and ignores copying the invalid data of that block.

Garbage collection begins to work when a block is full of data including valid and invalid data. When you want to delete data in block, this work depends on garbage collection which is the erase cycle for NADA flash memory. At this time the marked pages will get together as a block and the whole block can be deleted. But you can’t write directly on the page which you have written and you want to make a deletion. Over time, you find the blank pages are going to run out and you need more blank pages to store new data. This is because data can be only deleted in blocks. However, if you delete data on a page it isn’t really deleted, it is marked as deletion.
For SSDs the data on notebook can be wiped when it is necessary. Each block consists of more than one file we compare a block as a notebook and a file as one page of the notebook. Typically, SSDs use NADA flash memory to store data and a flash controller to connect the memory with the host computer. SSDs look like traditional hard drives, but they record data in different ways. In order to know what SSD trim is, first you need to understand how SSD works. However, when it comes to SSD, not everyone knows it clearly especially its terms, taking trim SSD for example.
Nowadays, SSD drives are becoming more and more popular due to its advantages such as less power usage, faster speed, and higher reliability.
