The Samsung 970 Evo Plus is one of the formidable new entrants to the Samsung NVMe SSD lineup. It comes with tweaked performance improvements and sustained throughput. Samsung’s Evo series has always been a clear leader in terms of speed when it comes to low priced NVMe based SSDs. The Samsung 970 Evo Plus improves the performance levels even further.

The drive comes with the same construction with a 64-layer stacked TLC (Triple Level Cell/3-bit) NAND and a Phoenix controller but offers an improved firmware. The SSD comes with the capacities of 250 GB, 500 GB, and 1 TB. The 2 TB capacity is expected to be available soon.

The drive comes with a warranty of 5 years. The sequential read and write speeds offered by the Samsung 970 Evo Plus is 3500 MB per sec and 3300 MB per sec respectively. The DTG (Dynamic Thermal Guard) functionality ensures that the drive will be capable of handling the longer and sequential file transfers. Samsung goes on record stating that the new 970 Evo Plus can handle workloads 53 percent better than the older generation Samsung 970 SSDs.

The Samsung 970 Evo Plus – like the 970 EVO offers you the TurboWrite functionality. It lets you handle all the consumer class or heavy workloads.

Comparison based on a few key parameters: Samsung 970 Evo vs Evo Plus

Let us compare the two NVMe SSD drives based on a few key metrics. As has already been indicated through the brief reviews above, both the drives come with almost equivalent performance except for a few minor differences.


Both 970 Evo and 970 Evo Plus come with the same M.2 2280 standard. You can find the same PCIe 3.0 x4 connectivity on either of them. The bandwidth available on the two drives reads 4 GB per sec. The 970 Evo Plus comes with a 96-layer TLC (Triple-Level Cell/3bit) NAND in comparison to the 64-layer TLC on the 970 Evo. However, you will find the same Phoenix Controller and NVMe 1.3 Protocol on both the options.
