Right now I myself use a 4-th SSD Samsung 840 without trim enabled. It's been 3 moths since, and they haven't returned since. After replacing them i hadn't turned on trim anymore. They both came back to me in a month and a half with a fired SSD. I just recently had 2 customers with a macbook that asked me to upgrade to an SSD. I can't really prove it, I my self, am a guy that needs hard proof, but this isn't a coincidence. Its not the laptop ( MacBook Pro 17" Mid 2010 I5, nVidia 330M ). If it were a motherboard problem, they would have found it. As I was saying, I work in a service, I have tech guys which are very good at what they do. As soon as I turn on trim, with in a month or so, my SSD dies. But for macOS 10.9 Mavericks 10. The Swift 5 runtime is included by default on macOS Mojave 10.14.4 or later. The Swift 5 runtime is a set of libraries that enable support for Swift, the programming language used to build Trim Enabler. Cant really explain it, not an OS X expert. Starting with Trim Enabler 4.3, you now require the Swift 5 runtime in order to run Trim Enabler. So I deal with a lot of laptops on a daily basis. Im at my 4-th right now ( thx God for warranty ). I fried 3 SSD Samsung 840 ( not the pro version ). The problem with the OS X Trim command it that it kills your SSD. Have DiskTester fill entire SSD with data three times to simulate use. ![]() Start DiskTester benchmark (block sizes 4 KB and 8 KB).Start AJA System Test benchmark (benchmark file size 16 GB).Only for second round: Install TRIM Enabler and reboot MacBook Pro.This gives us a total of four results:Ī detailed account of a round of benchmarking: This provides a good comparison between fresh out of box and well-used performance.įor the second round, we perform another secure erase, and then we send it through the two benchmark passes with TRIM enabled. We then complete the first round of benchmarks, which consists of running AJA System Test and DiskTester twice without TRIM. This resets the SSD to the state it shipped in, yielding the best possible performance. First, we perform a secure erase, which tells the controller to clear all blocks on the drive. ![]() We’re sending the Samsung 840 Pro SSD though two rounds of benchmarks.
