Hopefully yours says “TRIM Support: Yes”. System_profiler SPSerialATADataType | grep 'TRIM' If you want to see the TRIM status for your boot drive, execute the following Terminal command: You’ll be warned that data loss could occur, but I have yet to find an issue with dataloss on any SSDs I’ve done this with. To do so, open Terminal.app and paste in the following line: Using apps like SuperDuper or CarbonCop圜loner, its easy to back up their data and then install a fresh system on a new SSD, which helps to recreate the recovery partition.Īfter migrating user accounts and data back to the new drive, I like to enable TRIM, if the SSD supports it and most do. Aside from bumping RAM or upgrade operating systems, I will often recommend the replacement of a spinning hard drive with a modern solid state drive (SSD). Because the disparagement has nothing to do with the point(s) being argued.No secret, I help friends update the performance of their old Macs. If OWC SSD drives are not benefiting from the use of TRIM commands, it may be that they're not sophisticated enough to use the TRIM information.īTW, for future reference, the problem with disparaging by innuendo is that it undermines your credibility and intelligence. Interestingly, OWC SSD drives would also never see the delete operation as well, so without the TRIM command, it could never optimize as well as an SSD drive that used the TRIM command information. And this is an issue that *all* SSD drives would run into.

The underlying issue that TRIM attempts to solve is that, when files are deleted at the O/S level, the SSD drive never sees the delete - it sees a 'series of writes', so it actually does NOT have enough information to optimize page allocation. Basically, it explains how TRIM works *with* garbage collection to improve the performance of the SSD drive. Take a look at this article: Ask Ars: “My SSD does garbage collection, so I don’t need TRIM… right?” | Ars Technica.

Every other function should be self-contained.' All it should require is the data to write and the data to retrieve. 'A drive should not have to be told how to take care of itself.
