860 evo vs 870 evo – which samsung ssd is best for you?

Samsung has continued to excel in manufacturing exceptional devices since the release of its very first product, the black and white televisions in 1969. Through diversification, other devices such as SSDs have hit the market.  New SSDs are released on a regular basis, and keeping up with them can be challenging. Samsung’s current release, on the other hand, is well worth a look. 

The EVO series is so popular in some regions that it outsells every other SSD by far. Samsung intends to use 860 EVO vs 870 EVO to capitalize on that tried-and-true recipe in order to maintain its dominant and profitable market position.

EVO 870, the successor to the famous 2.5-inch SATA SSD EVO 860, was just announced by Samsung in 2021. In this article, we compare the two variants of the Korean SSD giant’s best-selling SSD

We will also cover features such as reliability, endurance, shock resistance, memory, encryption features, backward compatibility, software, and more. This much is known ahead of time: the outstanding 860 EVO and the 870 EVO are definitely a force to be reckoned with. 

860 EVO vs 870 EVO

Solid-state drive (SSD) is a type of computer storage device that stores data and programs. SSDs, unlike traditional hard disk drives (HDDs), contain no moving parts and are substantially faster. 

SSDs also come in a variety of shapes and sizes, as well as with a variety of ports. 2.5 inch and M.2 are the two most common SSD form factors. The most common connection types are SATA and NVMe.

Because it often produces higher burst speeds than the Pro series, the EVO series is a suitable choice for consumer workloads. It is worth noting that the high level of performance will only last you for a short period of time.

Although the 870 EVO does consume more power, it does feature a lot of similarities when compared to its predecessor the 860 EVO. Let us look at the pros and cons of both storage devices below.

Samsung 860 EVO vs Samsung 870 EVO: Features Face to Face

For many years, the Samsung 860 EVO has been one of the most popular SSD drives. Samsung SSD 870 EVO, the manufacturer’s official replacement, was released in early 2021, and we all wondered whether the new drive would be able to maintain its success. Let’s look at how these two devices compare in terms of features.

Samsung SSD Reliability

They both weigh the same at 0.19 lb.

Sequential Read Speed

The 870 EVO is 10 MB per second (or 1.82 percent) quicker than the 860 EVO in terms of maximum sequential reading speed.

The 860 EVO goes up to 550 MB per second, while the 870 EVO goes up to 560 MB per second.

Sequential Write Speed

At maximum sequential writing speed, the 870 EVO is somewhat faster than the 860 EVO. The new model is 10 MB per second quicker than the 860 EVO (or 1.92 percent faster).

The specs include:

  • 860 EVO: Up to 520 MB per second
  • 870 EVO: Up to 530 MB per second

Power Consumption

As stated above, the 870 EVO consumes more power than the 860 EVO

When Average

The 860 EVO consumes 2.2 W while the 870 EVO consumes 2.5 W.

When Maximum

When compared to the earlier model, the 870 EVO consumes more energy at maximum power output.

The specs are as follows:

  • 860 EVO: 4.0 W
  • 870 EVO: 5.0 W


The 860 EVO and the 870 EVO both have similar reliability metrics that are measured in Mean Time Between Failure. This is the projected amount of time a solid-state drive will normally perform between two critical hardware failures. They both feature an MTBF of 1.5 million hours.


The amount of data that may be written on an SSD within its warranty period is used to determine its endurance. When comparing the same capacity options, the Terabytes Written, or TBW, are identical.

The 860 EVO TBW statistics are as follows:

  • 250GB: 150 TBW
  • 500GB: 300 TBW
  • 1TB: 600 TBW
  • 2TB: 1,200 TBW
  • 4TB: 2,400 TBW

The 870 EVO TBW statistics are as follows:

  • 250GB: 150 TBW
  • 500GB: 300 TBW
  • 1TB: 600 TBW
  • 2TB: 1,200 TBW
  • 4TB: 2,400 TBW

Shock Resistance 

The 860 EVO and the 870 EVO have similar shock resistance at 1,500 G and 0.5 ms. 


There’s no denying that larger memory, particularly in solid state drives (SSDs) like the 860 EVO or 870 EVO, are popular today. This is a good technique to improve your device’s performance. Both devices feature the Cache memory and the NAND.

Cache Memory

The 512 MB Samsung Low Power DDR4 SDRAM is found in the 860 EVO and 870 EVO.


NAND, short for “NOT AND”, equips the Samsung 860 EVO and Samsung 870 EVO with V-NAND. 

Samsung refers to its 3D NAND technology as “vertical NAND,” or “V-NAND”.

Encryption Features

The encryption features of the 860 EVO and 870 EVO are similar and are as follows:

  • AES 256-bit Full Disk Encryption
  • Encrypted Drive (IEEE1667)
  • TCG/Opal V2.0

Backward Compatibility Interface

The 860 EVO and the 870 EVO are also compatible with SATA 3 Gb/s and SATA 1.5 Gb/s interfaces, albeit performance will be slower than with SATA 6 Gb/s.


Samsung Magician
Samsung Magician

Samsung Magician is a cool free tool that helps users check drive health, boost performance via a simple interface, and manage and safeguard data on Samsung SSDs linked to a desktop or notebook computer. Both 860 EVO and 870 EVO support this feature.


A manufacturer’s warranty is included with all Samsung products. This includes its SSDs. The Samsung 860 EVO SATA 2.5′′ Solid State Drive and Samsung 870 EVO SATA 2.5′′ Solid State Drive each have a 5-year guarantee, which may be void if the TBW restrictions are exceeded.

Standout Features

Other standout features offered by the SSDs include Auto Garbage Collection Algorithm, S.M.A.R.T, Intelligent TurboWrite, Trim, and World Wide Name. 


The 860 EVO 4TB 2.5 Inch SATA III Internal SSD is about $50 less than the 870 EVO 4TB 2.5 Inch SATA III Internal SSD. In most circumstances, it is not worth replacing a Samsung EVO 860 with a Samsung EVO 870 if you already have one installed. However, we recommend buying the EVO 870, even if the price is slightly higher than the EVO 860 at first.

Final Thoughts

Samsung has maintained its position as the leading mainstream TLC-based SATA SSD manufacturer in the market. The 870 EVO continues Samsung’s tradition of pioneering SSD technology, with enhanced reliability, performance, and compatibility to meet the demands of everyone from content creators to IT professionals. 

Samsung however makes little to no mention of performance, endurance, or any other criterion with which to compare the 860 EVO. The Samsung 870 EVO is a safe, dependable, and sturdy solution for people looking for the best consumer SATA SSD available. However, after comparing both storage devices it all boils down to personal preference and financial constraints. Alternatives to the 860 EVO vs 870 EVO include the Samsung 980 Pro and the Crucial BX500.
