Hi,

I recently purchased a used & refurbished late 2016 MBP 13" with a 256GB SSD and was expecting the SSD to benchmark at around the average 2GB/s + read but I am only getting around 1.3-1.4GB/s on the read. I have tried various benchmarks including BlackMagic Speed Test and the results are pretty similar. I am not expecting it to be the drive indexing as it has been a few days already.

Could it be a faulty drive or a faulty macOS installation?

Try without it. I think you might be closer to that 2 number.

Seems be in the correct ball park range to me.
The 2015 13" I'm trying out runs these speeds. 2016 should be closer to 2.

Yeah the 2016 should be achieving around 2-2.5GB/s read on the 256GB model. Apple claims 3.2GB/s read but I'm guessing that's on their larger SSDs. I'll try turning off filevault and see what kind of speeds I get.

I seem to have fixed it by erasing and reinstalling macOS on the drive and without File Vault these are the speeds I'm getting now.

Edit: Turning on File Vault seems to just freeze macOS. the system time gets stuck and the cursor turns into a beachball if I try and click on something. This problem also happened when I turned off File Vault. Should I let it do its thing?

Turned on File Vault again and the speeds have gone back to 1.3GB/s read and write :( At least it wasn't a faulty SSD.

Yes, Tons of people felt the same way, Including me when I first hot my laptop in 2016. I have the 2TB version and never saw over 3GB/s as Apple Claims. Why? the way they test and software they use isn't black magic. They test the drive from another computer, not the one the OS is installed on. It doesn't really matter. High Sierra will make things even faster so get ready for that.
