Samsung 970 EVO vs 970 EVO Plus vs 970 PRO


With all other components being equal, SSD is the single biggest factor that determines your PC’s performance.

Not only SSDs give you better read and write speeds, but they also have a better life expectancy, provide better OS/apps loading time, consume less power, and come with a smaller footprint compared to the HDDs.

These are some of the reasons why people are rapidly switching towards SSDs. For a long time, hard drives had the advantage of being cheaper. So people were using them as the backup storage for movies/games.

But now, thanks to ever-decreasing prices of SSDs, even that advantage is diminishing.

Samsung 970 EVO vs 970 EVO Plus vs 970 PRO

Samsung is a big brand when it comes to SSDs, with a long history of premium options. The 970 EVO, 970 EVO Plus, and 970 PRO are three popular SSDs in their lineup. But since all of them have slightly similar name and specs, choosing one over the rest can be difficult. To help you guys, we have decided a have a comparison between these three.


While the 970 PRO comes with 512 GB and 1 TB versions, the 970 EVO and EVO Plus are available in various sizes ranging from 256 GB to 2 TB.

Here we’ll test the 1 TB versions of these SSDs.

All three use V-NAND technology, have a Samsung Pheonix controller, and come in M.2 2280 form factor. Also known as Vertical NAND (or 3D NAND), V-NAND is the SSD technology using which flash memory call layers are stacked vertically on each other. This technology results in more storage size in the same space, faster read/write operations, and lower production cost.

The endurance rating is 1200 TBW in 970 PRO, but 600 TBW in EVO and EVO Plus.

The TBW rating is the amount of data (in TeraBytes) you can write on an SSD before its warranty voids.

For example, if you write 250 GB data on 970 EVO every day, it will take you more than 13 years to hit the 1200 TBW mark. While the content creators and videographers write this high amount of data on their drives every day, average PC users don’t do such tasks most of the time.

So a 600 TBW is more than enough for most people.

Data Transfer

The 970 EVO comes with up to 3400 MB/s sequential read and 2500 MB/s sequential write operations. For 970 EVO Plus and 970 PRO, these numbers are 3500 MB/3300 MB per second and 3500 MB/2700 MB per second.

The random read and write operation speeds depicted a similar story, where 970 EVO got 500,000 IOPS and 450,000 IOPS, respectively (4KB, QD32). Against these, the 970 EVO Plus got 600,000 IOPS and 550,000 IOPS. The 970 PRO stays somewhere in the middle with 500,000 random read IOPS and 500,000 random write IOPS.

As good as these numbers look, these are just official stats.

SSDs come with an SLC cache buffer that can quickly transfer a short amount of data. But once you transfer a file larger than that buffer, the workload increases and the transfer rate decreases.

The sustained sequential write performance is a better indicator in this regard. We transferred data through 970 EVO, 970 EVO Plus, and 970 PRO for 10 minutes and found their average sustained write speeds to be 1285 MB/s, 1705 MB/s, 2693 MB/s, respectively.

Game Loading Times

Other than this, we played different games such as Shadow of the Tomb Raider, GTA V, Borderlands 3, Red Dead Redemption 2, and Far Cry 5 on these SSDs. Although all of them performed well, it was 970 EVO plus who took the lead with roughly 10% faster loading times than 970 EVO and 5% faster than 970 PRO – on average.

Power Consumption

Power consumption is not an issue for desktop users, but you should note it if planning to use these SSDs on your laptop. While both 970 PRO and 970 EVO Plus consume almost 3.5 Watts while copying data, the 970 EVO consumes 4 Watts.


The Samsung 970 PRO is currently priced at almost 250 bucks on amazon – for a 1 TB version. Next comes the 970 EVO Plus. It was priced at $170 at the start, but now you can get it at $160.

The cheapest of them is 970 EVO. It was released at $180 and is now available at almost $145.

Samsung 970 EVO vs 970 EVO Plus vs 970 PRO: Conclusion

The 970 PRO is currently priced significantly higher than both EVO and EVO Plus, but since the performance level is only slightly better, paying more money is certainly a no-no.

That leaves us with two options: EVO and EVO Plus.

EVO Plus performs quite better than the EVO and is only $15 more expensive. This makes it the best bang for buck SSD out of these three.
