Samsung SSD 850 EVO (120GB, 250GB, 500GB & 1TB) Review

Back in 2011 (which seems like so long ago now!), we introduced our AnandTech Storage Bench, a suite of benchmarks that took traces of real OS/application usage and played them back in a repeatable manner. The MOASB, officially called AnandTech Storage Bench 2011 – Heavy Workload, mainly focuses on peak IO performance and basic garbage collection routines. There is a lot of downloading and application installing that happens during the course of this test. Our thinking was that it's during application installs, file copies, downloading and multitasking with all of this that you can really notice performance differences between drives. The full description of the Heavy test can be found here, while the Light workload details are here.
Fortunately the 850 EVO does much better in our 2011 Storage Benches, which are more representative of what a typical consumer would subject the drive to. In these tests the 850 EVO is actually more or less a match for the 850 Pro (excluding the 120GB model) and beats pretty much all of its main competitors (namely MX100 and Ultra II).

My guess is that Samsung doesn't have the ability to produce very much V-NAND. So the 850 PRO, and now the 850 EVO, are priced to encourage most people to choose SSD's from the 840 line rather than the 850 line, preventing demand for the 850 line from exceeding the supply.rms141 - Monday, December 8, 2014 - link
The absence of the Samsung 840 Pro from the Storage Bench 2013 section is pretty odd. Why wouldn't you include the previous generation's higher performing product? This is a little bit like publishing a GTX 970 review without including the GTX 780 for reference.Kristian Vättö - Tuesday, December 9, 2014 - link
You can always use the Bench tool to compare any and all drives that we have tested over the years:http://www.anandtech.com/bench/SSD/65

it doesn't make much sense to complain about the msrp when the drive is just now trickling to retailers. you're probably not gonna make a good deal on a 850 evo before christmas, but the prices will come down considerably in q1/q2 2015, they always do.that said, i wouldn't mind paying a couple bucks more for a 850, compared to a 840, since it's just the all around better drive and it's lower power consumption alone makes it the better option for laptops.
pitted against an mx100 it might be a tougher sell, but let's just wait a bit for the prices to come down and give the early adopters some time to beta-test the firmware for us in the meantime.

Does TurboWrite, native encryption, and TRIM work in RAID 0 on the 850 EVO? Thats the only way i would invest $500+ into a SSD still bottlenecked by Sata 6hojnikb - Tuesday, December 9, 2014 - link
All of that should work with appropriate motherboard/storage drives, because drive itself is not aware whenever is in RAID or not.hojnikb - Tuesday, December 9, 2014 - link

I just got a 1TB 840 evo for $369. No way the 850 evo is worth the extra $100.R3MF - Tuesday, December 9, 2014 - link
How do you conduct this review of a perfomance oriented SSD without discussing:1. m.2 format (or lack thereof)?
2. PCIe 3.0 4x m.2 performance (vs SATA 6G)?
3. NVME m.2 performance (vs SATA 6G)?
It is the end of 2014, who seriously spends £320 on a 1TB performance SSD without considering the high-speed m.2 drives just around the corner, to which a growing number of enthusiasts have empty slots on their shiny new motherboards?
