Our in-house testing has also shown that the TRIM Enabler hack has proven to be unreliable. It made a huge difference in terms of reliability.” “I used the trim enabler 1.1 initially, then realized that your self maintenance was far superior to using TRIM so I disabled it. As OWC customer Scott Gosling recently said in an email to us, In fact, enabling TRIM could actually hurt the performance and reliability of your OWC SSD, rather than help it. Especially note page two of this performance testing expert’s report where he feels so strongly about TRIM’s inefficiency that he calls call it “half-baked”…and that’s the kid friendly version of the phrase. The SandForce controller in our SSDs takes care of this “garbage collection” as well as performs various other tasks that keep your drive running at optimal speed, without the drop-off that you see with other brands. If you have an OWC SSD, though, you don’t need TRIM. There have been murmurings of a utility in Lion that will support all SSDs officially, and there have been several hacks to try and enable TRIM for all SSDs. As of right now, there is some basic TRIM support for Apple-branded SSDs in the OS, but third-party vendors are largely left out of the deal. With OS X Lion right around the corner, there’s been a lot of talk about its potential TRIM support. This allows for better performance for many SSDs. As solid state drives became more affordable, the TRIM command was introduced to facilitate “garbage collection” of deleted data, allowing the SSD to reset those “unused” blocks back to an “empty” state.
When you simply “delete” a file on a traditional hard drive, it’s not really “erased.” Instead, its location on the drive is reported to the OS as “empty, even though the ones and zeroes are still there, ready to be overwritten. On SSDs, however, overwriting data can take a considerably longer time than writing to “unused” space.
#Trim enabler for 10.6.8 mac os x#
Update 2: A number of users of pre-"Late 2010" MacBook Air models have reported that Mac OS X 10.6.8 does not enable TRIM on their machines.Before we get started talking about TRIM and why you should or should not enable it, let’s just grab a little background, so everybody is roughly on the same page. But that TRIM support had not been extended to all SSD-configurable Macs until the release of Mac OS X 10.6.8 last week. Update: To clarify Apple's TRIM support, the new MacBook Pros released in February shipped with a special build of Mac OS X 10.6.6 that included TRIM support for Apple SSDs. A number of users has actually reported significant declines in graphics performance with Mac OS X 10.6.7, so improvements with the new Mac OS X 10.6.8 are certainly to be welcome. User reports in the MacRumors forums and the Steam forums similarly point to significant improvements in graphics performance under real-world conditions. According to one set of benchmarks, Mac OS X 10.6.8 outperforms Mac OS X 10.6.7 in many measure of graphics performance, sometimes by a significant margin.
Mac OS X 10.6.8 also appears to have brought graphics improvements that have been most apparent to gamers.
The new native TRIM support does appear to limited to stock Apple drives, as users who have installed third-party SSDs into their machines have reported that TRIM is not enabled by the update. Support for TRIM has been included in OS X Lion since its early developer builds, but Apple has apparently decided to push the feature out to Snow Leopard users as well. TRIM is a feature that allows solid state drives (SSDs) to automatically handle garbage collection, cleaning up unused blocks of data and preparing them for rewriting, thereby preventing slowdowns that would otherwise occur over time as garbage data accumulates. One item of interest regarding last week's Mac OS X 10.6.8 update reveals that Apple has enabled TRIM support retroactively for solid state hard drives shipped in Apple-produced configurations.
