But now SSDs’ price has dropped down drastically, allowing users to upgrade their MacBook Pro’s SSD themselves at a much lower cost. In the past, this upgrade was quite expensive. Therefore, an upgrade in SSD is surely necessary. However, this amount of storage will be running out quickly if you have done a lot of heavy-demand works like photo editing or video. Check out this presentation by LSI's Kent Smith at the Flash Memory Summit in 2011 for more (specifically, slide seven).The MacBook Pro models from late-2013 to mid-2015 are often configured with 256GB or 512GB of solid-state drive (SSD) storage by default. But if you're dealing with exclusively incompressible data, DuraWrite won't help, and you're going to be missing TRIM support. In a typical use case, you're going to have some information that can be compressed. The rub is that DuraWrite requires compressible data to operate on. The reasoning behind this is that DuraWrite frees up space on the drive that can be used for garbage collection, similar to what TRIM already does.
Note also that OWC's official party line is that you do not need to enable TRIM on the Aura Pro due to SandForce's DuraWrite technology. If you want to do this right, follow the instructions linked above. They're often unreliable, though, and some are even outdated, compatible only with Snow Leopard or earlier versions of OS X. There's a bit of terminal window work to lift the Apple SSD requirement, but it's all covered in sufficient depth at Github.īe forewarned that there are programs out there written to enable TRIM support with a single click.
Fortunately, the restriction isn't hardwired. Without this, the process of reading, deleting, or moving data can slow down as the SSD maintains information that is no longer used. Unfortunately, Apple only enables TRIM on its own drives, in a move to perhaps discourage customers from going the aftermarket route. TRIM is the command that lets an operating system tell an SSD which blocks of data are no longer in use and can be wiped, preparing them for the next write.
