Good morning,

Since a couple of weeks I'm the proud owner of a Hackingtosh. It is sooo much faster than my iMac i7 (mid 2010) but even faster then my office Macbook Pro 15" i7 (2018).

So Im happy. That said, I want get the maximum out of my investment. So I did some benchmarks and found out that my NVMe drive was not doing the speeds it was advertised to do. Read is lighting fast but write, the first half a second it's doing 2100Mb/s then it takes a nosedive to around 600Mb/s and sometimes even lower.

Is this normal? Or is there something going wrong?

Thanks

Thanks for your reply.

 

I have passive cooling on the M.2 so the temp is not going above 41˚. But advertising with 2.300MB/s and only getting to 600MB/s that feel as a lot less performance.

 

But if this is normal, still love my machine ;)

Hahahah thanks,

 

Recap, I've should have gotten the pro version. It was the same price, but I read there where problems using it with an Hackintosh.

 

No matter, thanks for your feedback!
