The 2TB Samsung 850 Pro & EVO SSD Review
by Kristian Vättö on July 23, 2015 10:00 AM ESTIdle Power Consumption
Since we truncate idle times to 25µs in our Storage Bench traces, they don't give a fully accurate picture of real world power consumption as idle power consumption is not taken properly into account. Hence I'm still reporting idle power consumption as a separate benchmark because it's one of the most critical metrics when it comes evaluating an SSD for mobile use.
Unfortunately I still don't have a way to test DevSleep power consumption due to lack of platform support, but my testbed supports HIPM+DIPM power commands (also referred to as Slumber power), so the results give a rather accurate picture of real-world idle power consumption.
Idle power consumption is increased by a rather large margin. With a beefier DRAM controller and more DRAM drawing power, I was expecting higher idle power draw, but not over twice the power. Still, the Pro and EVO are among the most power efficient drives under idle, making them good for mobile use.
ATTO - Transfer Size vs Performance
ATTO is a handy tool for quickly measuring performance across various transfer sizes and it's also freeware that can easily be run by the end-user.

AS-SSD Incompressible Sequential Performance
Similar to ATTO, AS-SSD is freeware as well and uses incompressible data for all of its transfers, making it a valuable tool when testing drives with built-in compression engines (e.g. SandForce).

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.joyce.shue@verizon.net - Thursday, October 15, 2015 - link
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.Miller1331 - Tuesday, December 1, 2015 - 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.
