I tried searching, but didn't find anything on maintaining SSD health for the new macbooks. I've got a 2015 rMBP and I was wondering if there were any preventative measures to help maintain the life span of the computers SSD. I used to over provision my SSDs in my desktop, but does that still aid at all with the Macbooks? And why does disk utility not show a S.M.A.R.T. status for the partition or does it only show it for the physical drive?
Thanks.

Just don't fill it above about 95%-98% of its capacity, and you'll be fine. Unless it has some sort of defect from the factory, or you're writing hundreds upon hundreds of gigabytes per day, the SSD will be the last part of concern on that machine.

Perfect, thanks a lot.

I just swap out my SSD's in them after 6 months due to wear leveling, you can eat a drive fast by pumping that many read/write cycles through. I wish I could install some of the new enterprise grade units to negate most of the wearing on cells. otherwise Keep it to 75% used at most and wait for the size of drive to start shrinking once the built in over provisioning wears out.

External will not work for a scratch disk well, the latency and bottlenecks are a nightmare and cause kernel panicks far far too often. you can use an external for final output renders but that's about it nowadays ( 10.9/10.10 )

LOL, it works on Thunderbolt if its the TB3 ports in my Zbook Studio or 7510. I can not for the life of me get it to be stable enough on any of the 5 15" rMBP's that Apple has sent me one after another the last 2 months trying to use one as a scratch and final render output for a large and time critical project in FCPX and Premier Pro I had dumped in my lap. in the end I wound up doing it all in an OSX VM. but agreed to try and help see if we can find the issue or a fix with a few editors with same issues. especially where 4K or non Quicktime codecs are used. TB on OSX seems to be flakey as they come on very large file sizes ( 4GB+ ) or where you are doing a continual data stream to a container file.
USB has actually been most stable, however its a bottleneck for a scratch disk -

someone has 2 hackintoshes, but a VM on a Zbook 17 Gen3 saved my arse in this case.
