For full details of how we conduct our Iometer tests, please refer to this article.
Random read performance is unchanged from the 1TB models, but as we already noticed in the Storage Bench tests the 2TB models are more power efficient.
Despite having equal performance at low queue depths, the 2TB models don't performance as well at QD8 and QD16. It's a marginal difference, but it's an interesting observation that further speaks for the controller not being ideal for over 1TB of NAND.
Random Write Performance
Random write performance is also equivalent to 1TB Pro and EVO, but power consumption decreases, resulting in increased power efficiency.
Similarly, queue depth scaling is identical to smaller capacities.
As I see it, Samsung is pushing really hard to win over the whole market. The 850 Evo line is a substantial step forward. I really like the way PC starts working with an SSD rather than with HDD. I've bought one here http://hardware.nl/harde-schijven/samsung/ssd/mz-7... But you may find even a better offer on eBay, I think. Anyway, even for 85 euro this is a great purchase.
Can someone please explain the "Performance Consistenty" charts and how to read them? They change every time I switch the default and 25% OP even with the same drives... confusing.
I purchased the Samsung SSD 850 Pro to install in my new Windows 10 computer. I can't clone Windows 10 or anything to this drive. I've talked to Samsung for over 7 weeks and keep getting a new date for the release of their cloning software. I've tried 2 different cloning software and they don't work with this drive. Until Samsung updates the software for Windows 10 DON'T BUY.

Using 2 of these in a music production rig and they are monstersMeteor2 - Wednesday, November 23, 2016 - link
I don't think this reviews specifies what interface the 850 Pro uses anywhere.Meteor2 - Wednesday, November 23, 2016 - link
...until the last page. Would've thought it page 1 material, myself.
