Samsung 970 EVO vs 970 EVO Plus: Which One and Why?

Samsung has introduced a wide range of SSDs, which also include reliable NVMe SSDs. Both SAMSUNG 970 EVO and SAMSUNG 970 EVO Plus are well-known NVMe SSDs in the market.

Previously, it was quite simple to choose a Samsung SSD but now it’s a bit tricky, due to more variants. The SAMSUNG 970 EVO is a little bit slower than the 970 EVO Plus if we look at the theoretical performance space.

However, there are no questions of reliability and other things. Both NVMe SSDs are reliable and durable, comparing each of them. But, this is the thing that makes this decision tough.

Both the drives are not inexpensive if you are looking to buy a 1 TB or higher version. So, a prior research is important. So, don’t worry. I have done everything for you. Just go through this article and you will surely find it easy to make the final decision without any issue.

Samsung 970 EVO vs Samsung 970 EVO Plus: Best Pick?

What is the main difference between Samsung 970 EVO and Samsung 970 EVO Plus? The key difference for the SSDs is a better version of V-NAND technology. The new model Samsung 970 EVO Plus includes 96 layers of V-NAND. Whereas, the Samsung 970 EVO NVMe SSD includes 64 layers of V-NAND technology.

Comparing the features of both, it’s pretty clear that Samsung 970 EVO Plus dominates the 970 EVO model. Let’s explore the difference between both Samsung SSDs.

Samsung has introduced up-to 2TB variants for 970 EVO & 970 EVO Plus NVMe SSDs. Currently, you can obtain any of the stated variants 250GB, 500GB, 1TB, 2TB SSDs.

Note: If you’re intending to get an SSD for effective Read/Write speed 2 TB is the best choice. The higher variant includes impressive R/W speed. Before, investing in any NVMe SSDs consider the actual need, later on, proceed ahead to make a purchase.

The company says that these speeds are achieved through Samsung’s TurboWrite technology.

Read/Write Speed of SAMSUNG 970 EVO NVMe SSD

The Read Speed for 250GB/500GB/1TB is the same 3400 MB/s Whereas, the 2TB variant includes better Read Speed 3500 MB/s You can see an increasing Write Speed depending on the higher variant.

Comparing the Read/Write speed for both these products, it’s pretty clear that Samsung 970 EVO Plus is faster. Though there is no such big difference in “Read Speed”, considering the Write Speed of each variant Samsung 970 EVO Plus dominates the old model Samsung EVO 970.

Note: The Stated Read/Write might differ (Increase/decrease) depending on Operating System and your system’s processor.

Results: Again, the random 4K, QD32 Speed is higher in the 970 EVO Plus as compared to the 970 EVO. I haven’t added the QD1 IOPS, but they are also better in the 970 EVO Plus.

I have done these tests using CrystalDiskMark 8. The system configurations are Intel i5 8th generation with 8GB 3200 Mhz RAM.

It’s a better choice to invest in Samsung 970 EVO Plus because it’s the best in terms of data read/write speed, TBW, and most of the things. Considering the current market price Samsung 970 EVO Plus, 250GB & 500GB variants are available at a lower value compared to 970 EVO. Moreover, there is no such massive difference in price comparing to other variants too.

So, when you opt for the 970 EVO Plus, you will surely get a bit higher speed. But, the difference is not that much. So, you can also go for a lighter version (EVO 970) and be satisfied with the performance as well. But, if you ask me, I would definitely go with the SAMSUNG 970 EVO Plus.

Remember: Samsung 970 EVO Plus includes a newer version of Samsung 92-layer TLC V-NAND. Hence, it faster compared to the old Samsung 970 EVO model.
