Ubuntu is also looking at enabling TRIM automatically by having the system regularly run fstrim.

Android simply runs a fstrim task occasionally to TRIM the file system, fixing the problem that slowed down all those original Nexus 7s. In fact, this is the approach Google took with Android 4.3. RELATED: Why is My Nexus 7 So Slow? 8 Ways to Speed it Up Again It won’t slow down anything it’s just another housecleaning task the system has to perform on a schedule. In other words, fstrim can perform TRIM as a cron job.

This turns TRIM from a real-time operation into a scheduled task. Essentially, the fstrim command analyzes the file system and informs the drive which blocks are no longer needed, so the drive can discard them. Rather than simply issuing the TRIM command each time a file is deleted, the FITRIM feature can be used. Android also didn’t use TRIM until Android 4.3.īut there’s another way to use TRIM. Ubuntu and other Linux distributions don’t enable “discard” by default for your file systems, and you shouldn’t either.īecause the Linux kernel’s real-time “discard” TRIM operation doesn’t perform well, most Linux distributions - including Ubuntu - don’t use TRIM automatically.

Enabling TRIM similar to how Windows does - that is, using the “discard” option - results in the system actually becoming slower than if TRIM were not used at all. In other words, the Linux kernel handles such real-time TRIM commands in a slow, unoptimized way. It is not known when the kernels discard functionality will be optimized to work beneficially with current generation SSDs.” There are few reasons to use the kernels realtime discard support with pre-3.1 kernels. calls for trim supporting a vectorized list of trim ranges, but as of kernel 3.0 trim is only invoked by the kernel with a single discard / trim range and with current mid 2011 SSDs this has proven to cause a performance degradation instead of a performance increase. “The kernel implementation of realtime trim in 11.2, 11.3, and 11.4 is not optimized. It’s a bit dated, but is likely still true when it comes to performance: OpenSUSE’s wiki contains some detailed information from a developer who’s more familiar with the Linux kernel than we are. However, Ubuntu - and other distributions - don’t do this by default for performance reasons. Linux supports this when file systems are mounted with the “discard” option.

On Windows 7 and 8, Windows sends a TRIM command each time it deletes a file, telling the drive to immediately delete the bits of the file. The real reason Ubuntu doesn’t TRIM SSDs by default is because the Linux kernel’s implementation of TRIM is slow and results in poor performance in normal use. RELATED: What Is a Solid State Drive (SSD), and Do I Need One? Why Doesn’t Ubuntu TRIM By Default? TRIM was implemented in Linux back in December 2008, but Ubuntu isn’t using it by default.

That’s why modern operating systems, including Windows 7+, Mac OS X 10.6.8+, and Android 4.3+ use TRIM. In other words, if you don’t use TRIM, your SSD will slow down over time. The drive can then erase the sectors containing the file’s contents, so writing to the sectors will be quick in the future. With TRIM enabled, the operating system tells the SSD each time it deletes a file. Google fixed this by implementing TRIM in Android 4.3. This is a big part of the reason Google’s original Nexus 7 slowed down so much over time. After you delete some files and try to write to it again, it will take longer. Writing to the SSD’s sectors will be quick the first time. This means that an SSD will slow down over time. It can’t just “overwrite” the sectors in one operation - it must first clear them, then write to the empty sectors. Whenever you write a file to an SSD, the computer must first erase any data in the sectors it’s writing the data to. Solid-state drives (SSDs) work differently.
