Dude, honestly, just a report, I have a 1,2,3...24 SSDs in house, since 2012. You wanna know how many have died?
ZERO
Here is my secret to success if you want to know, as most posters in this thread already know or have probably pointed out (TL;DR):
If you are going to buy an SSD, NEVER, except when doing a quick BULK transfer of some sort, never go over HALF of the Storage capacity.
So let's say you want/need a mac with 16GB / 256GB of SSD? right? Then you actually need to buy a 16GB / 512GB, or settle for an 8GB / 512GB. And NEVER (try not to) go over 256GBs of use, i.e. try to maintain 256GB of FREE Space, this goes for iPhones too. I didn't even count those "ssd" drives. So add +8 SSDs, so 32 ssds, and NONE died.
The whole secret is trim and garbage collection...
Here is one other thing to take note:
That USED 256GB "section", is also NOT USED that much, (I mean there are software/app updates but), quite a bit of the 256GBs of the 512 SSD is in READ MODE, so you do quite a bit of READs, write's hurt more.
Lastly, DUDE you are spinning the roulette wheel, but the only number you need to be worried about is DOUBLE ZERO GREEN, why? Because you dropped $1000~ for Technology, if you get that 1/36 that dies, SHRUG?
That's life... in computers, by NOT USING your device you're defeating the whole purpose. i.e. LOSING TIME, which in some books EQUALS MONEY?!?
Good Luck Dawg!
