Samsung SSD 850 EVO (120GB, 250GB, 500GB & 1TB) Review
by Kristian Vättö on December 8, 2014 10:00 AM ESTAnandTech Storage Bench 2013
Our Storage Bench 2013 focuses on worst-case multitasking and IO consistency. Similar to our earlier Storage Benches, the test is still application trace based – we record all IO requests made to a test system and play them back on the drive we are testing and run statistical analysis on the drive's responses. There are 49.8 million IO operations in total with 1583.0GB of reads and 875.6GB of writes. I'm not including the full description of the test for better readability, so make sure to read our Storage Bench 2013 introduction for the full details.
| AnandTech Storage Bench 2013 - The Destroyer | ||
| Workload | Description | Applications Used |
| Photo Sync/Editing | Import images, edit, export | Adobe Photoshop CS6, Adobe Lightroom 4, Dropbox |
| Gaming | Download/install games, play games | Steam, Deus Ex, Skyrim, Starcraft 2, BioShock Infinite |
| Virtualization | Run/manage VM, use general apps inside VM | VirtualBox |
| General Productivity | Browse the web, manage local email, copy files, encrypt/decrypt files, backup system, download content, virus/malware scan | Chrome, IE10, Outlook, Windows 8, AxCrypt, uTorrent, AdAware |
| Video Playback | Copy and watch movies | Windows 8 |
| Application Development | Compile projects, check out code, download code samples | Visual Studio 2012 |
We are reporting two primary metrics with the Destroyer: average data rate in MB/s and average service time in microseconds. The former gives you an idea of the throughput of the drive during the time that it was running the test workload. This can be a very good indication of overall performance. What average data rate doesn't do a good job of is taking into account response time of very bursty (read: high queue depth) IO. By reporting average service time we heavily weigh latency for queued IOs. You'll note that this is a metric we have been reporting in our enterprise benchmarks for a while now. With the client tests maturing, the time was right for a little convergence.
The faster NAND and better IO consistency results in increased performance in our 2013 Storage Bench. The 1TB version shines in the test and isn't far from the 850 Pro, but the 500GB and 250GB models end up being middle-class performers. Especially the performance of the 250GB model is a bit underwhelming because it is beaten by the Ultra II, even though the 850 EVO should have a performance advantage thanks to V-NAND.

The over-provisioning figures in the article are larger than the actual over-provisioning values.The source of error is failure to account for the flash memory used for TurboWrite.
The correct values are:
120GB: 10.6%
250GB, 500GB and 1TB: 8.0%

Did you use Rapid Mode in those benches ?CricDasher - Thursday, March 3, 2016 - link
Samsung SSD 850 Evo is a life-changer for anyone who uses it. With the sleek and beautiful build quality, Evo 850 does obviously come with a great price tag.There are of course different capacities of the given product, but I preferred to use the 120 GB version, largely due to the relatively low price and my actual need of owning an SSD.
My major requirement was to install the Operating System and few other mostly used applications inside the SSD, so that the whole computer looks so fast. Samsung Evo 850 120 GB SSD has done the job fantastically for me so far and I highly recommend this product to everyone.
Out of the sellers online, GearBest seems to offer the best package since GB is a trusted source of products. They are offering a flash sale at the moment and you may try it to get it for a relatively a low price.

Samsung OWNS the SSD market! When I can buy an 850 EVO 500 GB model for just $110 and get for all intents and purposes, the BEST possible speed from a SATA 6 drive - there is REALLY NO POINT in buying ANY other brand!I mean the 850 EVO keeps up with, and sometimes even SURPASSES the 850 PRO - often in ways that will benefit the average power user/gamer more!
I wonder how much of that is due to the 6 GB of SLC write cache - as the 850 PRO series has no SLC NAND whatsoever!
Also, once the "Magical" storage capacity of 480 GB and above is reached, again, for JUST $110 - not only is that more than sufficient to hold my OS and all the games I play, but all SSDs tend to perform best at 480 GB and above, I would say for the 850 EVO series, this is DOUBLY TRUE! Due to the fact that the 500 GB model has a full 6 GB of SLC Turbo-write NAND (compared to 3 for the 250 and 120) - but it also has a full 512 MB of DDR3L on it!
I dunno why Anandtech has it listed as DDR2L memory, but it is indeed DDR3L RAM on ALL Samsung 850 series drives!

Hi Hardware Community,I know this article is quite outdated right now, nevertheless the actual topic of the authors "Final Words" bug me right now. Especially now that enough time for longtime-endurance tests has passed.
Anyway, I can´t choose between the Samsung EVO 850 1TB v2 (289€) and die SanDisk Extreme 960GB (281€).
So pricewise the "Pro" is even cheaper right now compared to the Samsung. But there are some obvious differences:
- TLC 3D V-NAND vs. MLC Planar
- 5 years vs. 10 years warranty
- 150 TBW vs. 80 TBW
- higher Peak vs. consistency
- Samsung Bugging vs. sudden death drives
My usage:
- Client for everything: gaming, programming, office, multimedia - averything
- gonna split it in system and data-partition
- gonne be in laptop that´s used as desktop
- battery is wasted, so no concern about power consumption
So, usually I use hardware until it´s broken so meaning about 8-10 years.
Still I want steady performance without sudden decline in speed like with the EVO 840 :C
I´d be really glad, if you could tell me your opinion on this :)

Awesome drivers! Anyone has a code for this? I checked several sites, likehttps://www.retailmenot.com/coupons/samsung,
https://dealspure.com/Samsung-Electronics-Promo-Co...
but couldn't find one. My mom has an aging Dell D830, which is very slow and I'm looking for a reasonably priced replacement, and I think this driver is great.

Yes this is a older review but just posting in 2020 on how my Samsung 850 EVO 500Gb has stood up to the wear & tear of every day computing. I have had my drive since 2015 in a computer that is on for many hours a day since I got the drive.The system gets used a lot so everything gets a really nice work out everyday. According to the Samsung software my drive is only at 2% of it's rated endurance lifespan. Not to bad for a drive that gets hit pretty hard everyday with reads and writes and to still have 98% life endurance left after all these years of use.
I read this review back in 2014 and it was one of the reasons I decided to get this drive for my system. I just came from a new write up form this site talking about a Midrive setup. What got me thinking about TLC nand was not the write up itself but a comment from a user and how they were saying just how bad QLC & TLC nand was and how they had low endurance lifespans.
Am I missing something here? My drive has TLC 3D V-nand made by Samsung and the drive is still at 98% endurance left on the SSD. Is Samsung's 3D V-nand better than regular TLC chips and lasts longer because of it. Yes my drive is getting up there in age and I plan on replacing it once I do a full system update and I will be getting a much faster NVMe PCI-e 4.0 drive.
As for the Samsung SSD I probably will use it to cache my 4 4TB hard drives since AMD has that caching setup in their platform and I can still find a good use for the Sata SSD I currently have. For now it is very snappy and the system feels very fast still with things such as Chrome or Firefox opening in half a second or Windows still booting up in a mere 7 seconds right after the bios post screen to the desktop so not worried about speed just quite yet.
