Most modern SATA drives have more or less the same sequential read performance and the 2TB Pro and EVO are no exceptions. Samsung drives do consume quite a bit of power under sequential read operations, but fortunately the 2TB EVO shows efficiency gains over the 1TB model.
Nothing special in the scaling graphs -- both the Pro and EVO reach their maximum at QD2.
Sequential Write Performance
Once again, the performance of 2TB models is equal to 1TB with the EVO having increased power efficiency.
Queue depth scaling is, unsurprisingly, similar to the 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.

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.
