Can anybody with a 1TB/2TB SSD in their MacBook Pro 2017 test the SSD performance using Blackmagic disk speed test ( free on the App Store ) ? Mine gives me 1850MB/s write and 2350MB/s read, which is lower than what apple advertises ( 2200 and 3100 respectively). I wanna know if it's just my unit or not.

I have a 2TB, 3.1 processor model and I'm getting the same. I'm also getting generally terrible performance compared to my Jan 2016 2.8 processor that I'll post about in a new thread:

The results are normal. The way Apple benchmark's the drive is it test it from another system, it's NOT the boot drive. Additionally they are sharing the highest the drive will ever reach in a specific test.

They are stupidly fast, that simple really, benchmarks mean nothing here they are very very fast that's all you need to know.

I did this and it doesn't make too much of a difference, still about 2 GB/s write and 2,4 GB/s read.
Maybe BlackMagic DiskSpeedTest isn't suited to test these ultra fast SSD?

And even after being reassured by Samuelsan2001, that all we need to know is that they are "very very fast", I'm still a bit curious in how Apple tested their SSD to achieve their figures ;)

Results may vary with the benchmark used and the type of data involved in benchmark . Attached you have a Corsair MP500 120 GB SSD PCIex4 . Best results with compressible data ATTO benchmark sequential read and write . Once benchmark use incompressible data results tend to drop (ASSD , Anvil Pro) . Disk is the boot and system drive . In Windows 10

Also drive size. Bigger drivers are faster since they can do more parallel reads and write operations.
