Samsung SSD 850 EVO (120GB, 250GB, 500GB & 1TB) Review
by Kristian Vättö on December 8, 2014 10:00 AM ESTPerformance vs. Transfer Size
ATTO is a useful tool for quickly benchmarking performance across various transfer sizes. You can get the complete data set in Bench. The performance of the 850 EVO scales excellently across all transfer sizes, although I should note that TurboWrite has its fingers in play as ATTO's test size maxes out at 2GB, which is small enough that it will get written to the SLC buffer.

Turbowrite is a default feature. It is marketing speak for optimizations to increase write performance in write workloads. It can't be turned on or off.erple2 - Wednesday, December 10, 2014 - link
Well, it has to be able to be turned on/off, as Kristian has a chart showing the difference in write speeds with it on/off. However, unlike "RAPID", there is no downside to leaving it on.geniekid - Monday, December 8, 2014 - link
Well written conclusion.andrewbaggins - Monday, December 8, 2014 - link
It's hard to understand why your SSD reviews fail to include Idle Power Consumption charts. For the hundreds of millions of PCs and laptops in use which do not support the so-called Slumber Power it would be far more useful if you included a chart for typical or average power consumed during Idle state.metayoshi - Monday, December 8, 2014 - link
"Hundreds of millions of PCs and laptops in use which do not support the so-called Slumber Power."Woah... I don't know where you got that "hundreds of millions" number from, but any system that supports SATA is able to support Slumber. Slumber has been in the SATA spec since forever, and pretty much all 2.5" drives, and some 3.5" drives support this power state.

P.S. As an example, I have a Core 2 Quad Q6600 sitting in my cubicle at work on an Asus PSE WS Pro motherboard. I have no Idea how old this thing is, but it's running a SATA-II 3.0 Gbps interface, and that great grandfather of a system supports HIPM+DIPM, and does Partial and Slumber on a variety of SSDs and HDDs.eanazag - Monday, December 8, 2014 - link

I think an 120gb 850 evo usb thumb drive would be awesome .dwade123 - Monday, December 8, 2014 - link
Realworld: all modern ssds have similar windows boot and game loading time. All these synthetic tests are just for reviewers to have something talk about, and marketing purposes. Meh.StrangerGuy - Monday, December 8, 2014 - link
I would rather want a SSD that has 90% of a MX100 but only 50% dollar per GB, instead of extra performance that 99% of SSD buyers will not never benefit for more money.
