Samsung 980 pro vs 970 evo plus – which ssd is best?

Is your computer too slow? Are you looking for a way to enhance its performance? Have you thought about a new SSD? Today we’re comparing two SSDs, Samsung 980 PRO vs 970 EVO Plus, to help you make the best choice.

Okay, first things first. You want the best SSD (solid state drives) because it allows faster access to the data (operating system, images, games, etc.). And it improves your computer performance. 

And here we’re talking about two models of Samsung SSDs, the latest one and the one from 2019, which is still on the list of top SSD solutions. 

Let’s check their performance, price, capacity, loading time, endurance, reliability, warranty, and other essential features and solve your dilemma.

Samsung 980 PRO vs 970 EVO Plus

So, why are we choosing to analyze two Samsung SSDs? Well, the first reason is that they are both excellent SSDs. One more reason is that Samsung released one of the first mass-market flash SSDs which impacted the switch from HDD (hard disk drive) to SSD over the years. 

They seem to be veterans in innovation technology. They have been pretty good for SSDs ever since they launched the world’s first high-volume Windows XP notebook using SSDs, back in 2006.

Believe it or not, Samsung started as a grocery trading store back in 1938 and first entered the electronics industry in 1969. 

As you might guess, their first products were black-and-white TVs. Still, over the years, they expanded to printers, HDDs, and later to home appliances, LCD and LED panels, mobile phones, memory chips, NAND flash, SSDs, televisions, digital cinemas screens, and laptops.

Before we jump into the differences between these two SSDs, let’s focus on the models within each one and compatibility as one of the significant pre-conditions before buying an SSD.

Basically, both Samsung 980 PRO and 970 EVO Plus have four models, depending on the capacity and ranging from 250GBs to 2TBs. So, when choosing the SSD, you need to consider what capacity you need for the best performance. 

The second important thing is compatibility. You need to check whether the chosen SSD is compatible with the device and its model. You can check it on the Samsung SSD Finder page, and it won’t take more than a few seconds.

Features Face to Face

And now, we are ready to dive deep into the features of Samsung 980 PRO vs Samsung 9700 EVO Plus. Fasten your seatbelts, here we go!


When it comes to capacity, both SSDs have four models, 250GB, 500GB, 1TB, and 2TB, and depending on the capacity, all other performances and features will vary.

Read speed

You probably know that there are two metrics regarding read/write speed, sequential and random. The difference is that you use sequential read speed when accessing a large file

On the other hand, random read speed is related to opening small files, such as opening a Word document while launching Chrome. 

Sequential read speed

Now, sequential read speed is where Samsung 980 PRO wins big time. Its read speed is up to 7,000 MB/s makes a huge difference from Samsung 970 EVO Plus, which reaches up to 3,500 MB/s, making it a perfect choice for gamers.

Random read speed

Things become a bit more complicated when it comes to random read speed. And here, we have Q1 (worst-case scenario) and Q32(best case scenario).

And if you look at the chart, you will notice that in a worst-case scenario, Samsung 980 PRO and Samsung 970 EVO Plus are very close to each other (19,000 IOPS vs 22,000 IOPS). Still, when it comes to the best-case scenario, Samsung 980 PRO wins again with 1,000,000 IOPS.

Write speed

Write speed is important when copying or transferring a file from one location to another. Depending on the size of the file, it will reflect sequential or random write speed. 

Sequential write speed

As you might guess, Samsung 980 PRO is a real pro for sequential write speed. It goes up to 5,100 MB/s, while Samsung 970 EVO Plus maximum goes up to 3,300 MB/s. 

Random write speed

And again, with a random write speed, we have a tight situation in a Samsung 980 PRO vs 970 EVO Plus battle. In the worst-case scenario, Samsung 970 EVO Plus shows even better results (up to 62,000 IOPS) than Samsung 980 PRO’s 60,000 IOPS. 

Of course, in a best-case scenario, Samsung 980 PRO is winning with up to 1,000,000 IOPS while 970 EVO Pro can reach up to 560,000 IOPS maximum.

Power consumption

If power consumption is an important factor when purchasing, you’ll be glad to know that there’s a slight difference between Samsung 980 PRO and 970 EVO Plus in average power consumption. 

While Samsung 980 PRO consumes on average from 5 W to 6.1 W, 970 EVO Plus consumption ranges from 5.0 W to 6.0 W.

Software loading time

When it comes to software loading time, it might be valuable for you to know that it largely depends on the random read speed. The higher the speed is, the shorter the loading time will be.

Of course, it’s not the only factor impacting the software loading time, and therefore the actual results can vary. That’s how Samsung 970 EVO Plus can boot in 10 to 26 seconds, while 980 PRO needs an impressive 4 to 10 seconds, both on Windows 10. 


Despite the capacity difference, both Samsung 980 Pro and 970 EVO Plus have the same endurance, which will vary depending on the capacity.

  • 150 TWB for 250GB,
  • 300 TBW for 500GB,
  • 600 TBW for 1TB, and
  • 1,200 TBW for 2TB.

NAND, Controller, and DRAM

When it comes to memory storage, comparing Samsung 980 PRO vs 970 EVO Plus, they both use V-NAND 3-bit MLC, so there’s no difference.

As for the controller, Samsung 980 PRO comes with the Samsung Elpis Controller. At the same time, Samsung 970 EVO Plus was released with the Samsung Phoenix Controller but was swapped to Elips in 2021. 

Then how will you know what controller you have if you buy 970 EVO Plus? Samsung changed the part number from MZVLB1T0HBLR to MZVL21T0HBLU on the sticker atop the drive. 

The problem is that this number is not on the box. The only hint is that the older version box is horizontally oriented, while the new version is vertical.

Now since controllers represent one of the essential parts of the SSD and the new version showed to be better in some situations but worse in others, in this part, Samsung 980 PRO wins.

And if you want to know what cache memory the SSDs have, check what DRAM is used and if the SSD has one. Yes, there are some SSDs without DRAM. 

But luckily, both Samsung 980 PRO and 970 EVO Plus have it, though Samsung 980 PRO leads a bit with up to 2GB Low Power DDR4 SDRAM and 970 has up to 1GB.


As you might guess, reliability refers to the ability of an SSD to continue performing its intended function for a specified period under specified operating conditions.

Both Samsung 980 PRO and 970 EVO Plus have up to 1.5 million hours of reliability.


The good thing with these SSDs is that they have a 5-years warranty, making them a pretty safe investment. 

Standout features

Let’s be honest; if we had to choose only one feature for both of these SSDs, it would be the speed. And, as you might guess, the Samsung 980 PRO is a bit faster. 

And the second thing is the 5 year warranty, which guarantees that you’re buying an SSD that will last. 


Like any other product, the latest models are more expensive than the previous ones. That’s why the price of the Samsung 980 PRO is higher than Samsung 970 EVO Plus. 

Is it worth the price? Well, yes, according to Amazon users.

Samsung 980 PRO SSD was rated 4.8 out of 5 stars by more than 10,000 Amazon users. Samsung 970 EVO Plus has excellent reviews, with almost 20,000 Amazon users rating it 4.9 out of 5 stars.

Samsung 980 PRO vs 970 EVO Plus was the battle of Titans. These two are excellent SSD solutions, especially if you’re looking for the best way to speed up your device. 

If you need quick access to frequently used files and programs, and if the ultimate speed is what you need, you might want to go for Samsung 980 PRO.

But if you want excellent performance, but without the super speed and with a more accessible price, you might want to consider the still competitive Samsung 970 EVO Plus.
