Not sure if I should try to embed the screenshots but I’ve added my description to the gallery.
There was some uncertainty when the older HDN724040ALE640 (0S03665) tested slower than previously, it was because the test was done on a different volume (and somehow it makes alot of difference). Luckily the faster volume is for games and its 400Gb, the other is storage 3.2Tb.
The new HDN726040ALE614 (0S04005)(which was released in Feb 2017, and I recieved mine today) got 200k in ATTO from 4kb to 64Mb test data. The previous gen with half the cache (64Mb vs 128Mb) got 174k from 16kb to 64Mb test data, and was significantly behind the 0S04005 when the test data was between 512b to 4kb.
In crystal diskmark once I had recognised that I must use volume e to give the best show of 0S03665, then 0S03665 was 75% of the performance of 0S04005.

I downgraded my storage driver because of a BSOD:
(it might have been I was trying to jam too much onto a hard drive so I could do some better partitions. I did that alright I made a 4Gb instead of 400Gb and I used minitool partition wizzard but I wanted a clean perfectly 400Gb ended up with 390Gb for some reason.)
