Slow 512GB SSD on iMac 5K 27" 2019 ?

[sterretje75]

I just bought a brand new 2019 iMac 5K, 27", 3,7 GHz i5 with 8 GB of RAM and a 512 GB SSD.

Running Blackmagic Disk Speed Test gives an avg. write speed of 688 MB/s and a read speed of about 808 MB/s (see attached screenshot). I would have expected at least a factor 2 faster speeds.

Anyone else experiencing these 'low' speeds?
