As a result, writing data to SSD media is very fast as long as empty pages can be used, but slows down considerably once previously written pages need to be overwritten. In SSDs, a write operation can be done on the page-level, but due to hardware limitations, erase commands always affect entire blocks. If they are considered to contain data, the contents first need to be erased before a write operation can be performed reliably. NAND flash memory cells can only be directly written to when they are empty. totaling 512 kB per block in case of the 4/128 combination). SSDs store data in flash memory cells that are grouped into pages, with the pages (typically 4 to 16 kB each) grouped together into blocks (typically 128 to 512 pages per block, e.g. For traditional hard disks, this is no different from writing an empty sector, but because of how some SSDs function at the lowest level, an overwrite produces significant overhead compared to writing data into an empty page, potentially crippling write performance.

While this often enables undelete tools to recover files from traditional hard disks, despite the files being reported as “deleted” by the operating system, it also means that when the operating system later performs a write operation to one of the sectors, which it considers free space, it effectively becomes an overwrite operation from the point of view of the storage medium. Since a common SSD has no knowledge of the file system structures, including the list of unused blocks/sectors, the storage medium remains unaware that the blocks have become available. Contrary to, for example, an overwrite operation, a delete will therefore not involve a physical write to the sectors that contain the data. Delete operations are typically limited to flagging data blocks as “not in use” in the file system. I found a great utility to enable TRIM on 10.6.8-10.9.5: Trim Enablerĭon’t forget to reenable it after each OS X System Update.īecause of the way that file systems typically handle delete operations, storage media (SSDs, but also traditional hard drives) generally do not know which sectors/pages are truly in use and which can be considered free space.

Makes it easier to reenable after a software update.
Second, Trim Enabler has a feature to check on startup. First, Chameleon has some compatibility issues. I switched my favorite utility from Chameleon SSD Optimizer to Trim Enabler. You can check your TRIM status from the System Profiler/System Information under SATA by selecting your device.

Not only that, but if you manually enable it yourself, it is then disabled during any OS upgrade (i.e. Apple introduced it in 2011, but believe it or not, even today, Apple refuses to automatically enable TRIM for 3rd party SSD drives. Technology was needed to offset this failing. As a result, the way that operating systems traditionally use these devices lead to progressive performance degradation and even shortened lifespan. However, it’s also possible that TRIM really should be enabled but something messed up in the automatic detection process.At the device level, SSD drives function entirely differently then conventional mechanical disks. Perhaps it’s a a very old solid-state drive.

If TRIM is disabled, it’s possible that Windows knows something you don’t, and TRIM shouldn’t be enabled for a drive. Windows should automatically enable TRIM if you have a modern version of Windows with a modern solid-state drive. If you see DisableDeleteNotify = 1, TRIM is disabled. That’s a double negative, which means “DeleteNotify,” also known as TRIM, is enabled.) (This is a little confusing at first glance-with a value of 0, the DisableDeleteNotify option is disabled. Everything is good and you don’t need to worry about it. If you see DisableDeleteNotify = 0, TRIM is enabled. Run the following command in the Command Prompt window: fsutil behavior query DisableDeleteNotify On Windows 7, open the Start menu, search for “Command Prompt”, right-click the “Command Prompt” shortcut, and select “Run as Administrator.”
