Newer operating systems also support the TRIM command, whereby the OS notifies the SSD that it has deleted specific files so that the SSD can better manage the GC process to recover that space earlier and prevent saving and moving all that invalid data. On hard disk drives (HDDs), the now-invalid data remains there and can be directly overwritten by the system to store new data. You will be notified of the enabling by this message NTFS DisableDeleteNotify 0. Open the command window and run fsutil behavior set disabledeletenotify 0 commands. For that, users need to use the command prompt again. When files are deleted in an operating system such as Windows, the OS just marks its internal file table indicating that the file is deleted. You can do enable TRIM on your SSD Windows 10, 8, 7. SSDs incorporate advanced controllers that manage the NAND Flash storage. The Garbage Collection process occurs automatically, usually during a system idle, and as it is a vital part of the functioning of the drive. Kingston® uses various controllers that leverage proprietary technologies to conduct Garbage Collection (GC), the purpose of which is to keep as many empty blocks as possible so that when the SSD has to write data, it isn’t waiting for a block to be erased. This process is called Garbage Collection. Click the upper-right icon and select Settings. To write to an already used block of data, an SSD controller would first copy all valid data (that which is still in use) and write it to empty pages of a different block, erase all the cells in the current block (both valid and invalid data), and then start writing new data to the newly erased block. To enable SSD TRIM: Go to the Storage page and select the storage pool consisting entirely of SSDs. Before data can be erased, all the valid data (pages) from the original block must first be copied and written into the empty pages of a new block. Flash memory is divided into blocks which are further divided into pages data is written on a page level and data is erased on a block level. They have to go through a Program/Erase cycle. Unlike a hard disk drive (HDD), SSDs and other NAND Flash storage cannot overwrite existing data. The goal of garbage collection is to periodically optimise the drive so that it runs efficiently and maintains performance throughout its life. In the world of SSD technology, the terms Garbage Collection and TRIM are often thrown around, but what do the terms really mean? In this article, we’ll look at Garbage Collection, how it works, and how this relates to the TRIM command.
