If you are conflicted between 840 EVO vs 850 EVO, you are not alone. Since both SSDs share many identical specifications, it can be challenging to distinguish between the two.
So how do you compare them? Ultimately, which one is better?
Stop racking your brain as we are here to help. Let’s figure it out and make the final decision!
840 EVO Vs 850 EVO: Which One Is Better?
The 840 EVO and 850 EVO are considered highly efficient SSDs and are popular among users. In order to make an informed decision, we have to examine their common features and a few crucial differences.
First, let’s talk about their similarities.
840 EVO and 850 EVO bear a great resemblance in terms of storage capacity. Both offers 120 GB, 250 GB, 500 GB and 1TB.
A small difference is the 840 EVO is available at 750 GB while the 850 EVO is not. In return, the 850 EVO has sizable storage capacity options at 2TB and 4TB.
Sequential Read And Write Speed
This specification applies particularly to large files such as music, movies, videos, and images.
The 840 EVO and 850 EVO share identical Sequential Read Speed of max 540 MB/s and Sequential Write Speed of max 520 MB/s.
But what does this mean for you as a user?
For example, let’s assume that you are moving a 2GB movie from one folder to another. Given the Read and Write Speed of both SSD, it would take only around four seconds to complete this task.
The 840 EVO and 850 EVO are both very efficient in reading and transferring big data. If you work a lot with multimedia files, these SSDs would be an excellent option.
4K IOPS (4K Input/Output Operation Per Second) Read Speed
While the Sequential Read and Write speed is for relocating files, 4K IOPS determines how fast a program will open. 4K IOPS Read Speed, in particular, is the speed of which your SSD can read small files (usually 4KB in size).
In the context of performance, SSDs 4K IOPS is what helps your PC or Operating System loads faster.
Both the 850 EVO and 840 EVO have the 4K IOPS Read Speed (QD1) of Max 10,000 IOPS.
If you compare this to an HDD, which only has around 80-150 IOPS, the two SSDs perform significantly faster and more efficiently at the same task.
Now that we have gone over their similarities, let’s tackle a few important differences between the 840 EVO and 850 EVO.
4K IOPS Write Speed
A significant distinction between two SSDs is the 4K IOPS Write Speed, which determines how fast an SSD can put read 4K data into a program.
The 4K Write Speed of 850 EVO is Max. 88,000 IOPS (120GB/250GB). And that of the 840 EVO is only Max 66,000 IOPS (250GB) and Max 33,000 (120GB).
While both SSDs are equally efficient at reading your data, the 850 EVO is much faster at loading and opening up your program.
Currently, most models of the 850 EVO are cheaper than that of the 840, except for the 1TB level. As of 2020, the most budget-friendly 850 EVO you can get is 250GB for around 100 dollars.
Ultimately, the 850 EVO is a better deal for your wallet.
840 EVO vs 850 EVO, which one should you choose? It depends on your needs and also your budget. Although the 850 EVO does outperform the 840 EVO, both SSDs are of high quality and are excellent choices.
We hope our review will help you make the most informed decision.
