[QUOTE="Lifeisabeach, post: 1839286, member: 38864"] Coincidentally enough, I just put that exact same SSD in that same model Mac mini. I get similar results using Blackmagic's software, so rest assured you didn't get a lemon. Bear in mind that WD hedges the specs by saying "up to" 500 MB/sec. Reaching that speed depends on a lot of variables, and the hardware in the 2014 Mac mini may not support that. How the drive is formatted (APFS vs HFS, for example) may impact it also. For comparison's sake, the Apple SSD in my 2019 MacBook Air has write speeds of around 1000 MB/sec. But this is much faster hardware, including the SSD itself. Even by WD's best case scenario, their drive is still half the speed of the one in this MBA. I have another one of these WD Blues in a USB-C enclosure, so let me test that for laughs on my MBA or iMac (also 2019) to see what results I get, along with the old OWC drive that I just pulled out. The speeds should be close to what they'd be internally on the newer Mac. I'll post back with a followup. [/QUOTE]
