Kynyo Posted February 16, 2014 Share Posted February 16, 2014 I have a Samsung 840 Pro 128GB SSD. A look with DriveDX gives me 99.0% @ SSD Lifetime Indicator Now I'm wondering if that it's a bug or a really warning! Any help is appreciated.

Kynyo Posted July 8, 2014 Author Share Posted July 8, 2014 After five months it drops from 99% to 98% lifetime.What can I do? If i Shrink disk (for OP) it will be OK? I guess it will be around 15GB just for OP. I wrote around 2.8TB till now.

GokieKS Posted July 9, 2014 Share Posted July 9, 2014 NAND in SSDs are rated for a certain number of program/erase cycles, which basically means each block of NAND can only be written to so many times before they wear out. What you are seeing is normal wear on a SSD. The only way for you to not have that number drop is to not write to the SSD. The short story: don't worry about it. In almost all consumer usage models, the NAND in a SSD will last longer than the SSD will remain useful (due to size, performance, etc).

Picasso Posted July 11, 2014 Share Posted July 11, 2014 Hi, anyone has a solution to enable TRIM in 10.9.4? I know that is the most important factor for the life of the SSD - I lost a Vertex 4 for not enable this. I was reading the command line as I paste below has some problem: TRIM enabled by using the following commands. sudo cp /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage /IOAHCIBlockStorage.originalPatch the file to enable TRIM support:sudo perl -pi -e ‘s|(\x52\x6F\x74\x61\x74\x69\x6F\x6E\x61\x6C\x00). {9}(\x00\x51)|$1\x00\x00\x00\x00\x00\x00\x00\x00\x 00$2|sg’ /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage Most people recommend a soft called TRIM ENABLE, but it's not free. Any recommendation? Thanks. Link to comment https://www.insanelymac.com/forum/topic/296113-ssd-question/#findComment-2039647 Share on other sites More sharing options...
