Samsung 970 EVO vs 970 Pro: Which one is the best?

The Samsung 970 EVO can be considered as the younger brother of the 970 Pro. But, it’s a tough competitor to the elder one because of its impressive read/write speed and other features. But, if you are looking to choose one of these but you are confused, I am here to help you.

Both Samsung 970 Evo and Samsung 970 Pro are using the same Penta-core, Samsung Phoenix controller. Both have the same Low Power DDR4 DRAM. But, the main thing that is creating a difference is the type of NAND. The Samsung 970 Pro SSD has a much reliable 3D MLC NAND as compared to the 970 Evo’s TLC 3D NAND. This is the reason the 970 Pro is capable of delivering a comparatively higher data read/write speeds.

In this article, I am going to do a clear comparison of both the SSDs so that you are able to make a perfect decision by the end of it. Now, without any further delays, let’s get started.

Let’s compare the theoretical specs that Samsung is promising with these products. All the information is collected from official sources.

With these specs, you can see that both the SSDs are offering pretty similar features to the users. But, let’s actually see the practical results using the benchmark scores.

The Samsung 970 Pro only has two storage variants i.e. 512GB and 1TB which is surely a disadvantage for people who are looking for a very low storage variant such as 256GB. Also, if you want a high storage space such as 2TB, the 970 Pro doesn’t have that for you.

Let’s compare the synthetic benchmark scores of both these SSDs and see how well they can manage the stresses. The tests were done on an Intel i5 8th Gen processor with an 8GB, 3200MHz RAM. The results may vary depending on the overall system specs and the total space filled on your SSD.

Parameter (Avg.)Samsung 970 Evo 1TBSamsung 970 Pro 1TB
Sequential Read2,325 MB/s2,385 MB/s
Sequential Write1,967 MB/s2,131 MB.s
Random 4KB Read53.4 MB/s61.2 MB/s
Random 4KB Write147.1 MB/s152.2 MB/s
Deep Queue 4K Read1158.6 MB/s1,247.6 MB/s
Deep Queue 4K Write987.3 MB/s996.3 MB/s

Note: The SSDs were 100% when the test started. I filled them completely and then calculate the average speed. The speed will decrease as the space starts to fill up.

Let’s look at the results. It’s very tough to decide a clear winner. Both the SSDs are beating each other in different areas. But, the 970 Pro is slightly better in terms of data reading.

Now, let’s compare how well these SSDs perform in the real-time applications. I tried running my OS and several software/games with the both. Below are the results.

OS/SoftwareSamsung 970 EvoSamsung 970 Pro
Windows 10 (Intel i5 8th Gen)Ready to use in 26 SecondsReady to use in 24 Seconds
Google ChromeWithin 5 SecondsWithin 4 Seconds
Adobe Photoshop~18 Seconds~17 Seconds
Fortnite~49 Seconds~29 Seconds
Tomb Raider~25 Seconds~23 Seconds

Again, the results are pretty similar. However, if you look closely, the 970 Pro is offering a better experience when we talk about the real-time applications. It is capable of helping you run your system and apps more efficiently.

Endurance is another one of the main factor that may affect your decision. Let’s compare the total endurance offered by these both SSDs.

Version (Capacity)Samsung 970 Evo (TBW)Samsung 970 Pro (TBW)
250GB150150
500GB300300
1TB600600
2TB1,2001,200

You can see that the 980 Pro has a better TBW rating to offer. However, the 250GB and 2TB variants are not available.

Let’s the core technical aspects and compare them to have a better idea about the capabilities of these SSDs.

NAND Layers6464
Cache Type Low Power DDR4 SDRAM Low Power DDR4 SDRAM
ControllerSamsung PhoenixSamsung Phoenix
Controller ConfigurationsPenta-Core, 8-ChannelsPenta-Core, 8-Channels

You can see that there is almost everything similar in both these SSDs. The main difference is between the type of NAND, as we discussed earlier. The 970 Pro SSD is using the MLC NAND which is more reliable and better than the 970 Evo’s TLC NAND.

The 512GB variants of Samsung 970 Pro is cheaper than the Samsung 970 Evo. But, the 1TB variant is way expensive as compared to the Evo’s 1TB variant. However, the prices keep varying. So, I would suggest you checking the live prices for an accurate comparison.

I would say buying any of these would be a great choice for you. But, if you really want to make single choice, the 970 Pro 1TB variant is great in terms of read/write speed, practical performance, and endurance as well. I would like to add that the 970 Pro is a perfect solution for hardcore users.

Whereas, the 970 Evo offers an impressive Price-to-performance ratio. The endurance (TBW) might be low but it is still enough for an average user and even for gamers. Also, the price is pretty affordable as compared to the 970 Pro. So, as a normal PC user, I would surely go with the 970 Evo if I have to make this decision. But, if I am about to do huge data read/write tasks, I would choose the 970 Pro for sure.
