Samsung launched a replacement for its ever-popular 970 EVO. The new 970 EVO Plus becomes the mainstream NVMe SSD storage for hardcore gamers, professionals, and enthusiasts alike.

Samsung packed the SSD with its new V5 flash technology and added a performance bump of 3.5 GB/s. More so, the drivers boast hardware encryption support, 1,200 TB of endurance, and a whopping 5-year warranty.

Even more, it hits the shelves with the same price tag as its predecessor: $129.99 for the 500GB version; and 349.99 for the 1TB version (Samsung)

The Samsung 970 EVO Plus SSD: the more layers the better

The new SSD storage has a sequential read speed of 3,500 MB/sec, and a sequential write speed of 3,300 MB/sec.

It offers solid overall performance with an excellent software package. Performance and efficiency are better than its predecessor. Also, it has a lower MSRPs.

As a con, it could use further efficiency optimization.

The 3D NAND layer crazy began in 204 when IMFT (Intel/Micron), Flash Forward (Toshiba/SanDisk) and Sk Hynix launched storage systems packing 96-later NAND. It was a great improvement from previous 64-layer NAND technologies.

However, Samsung hasn’t announced the exact number of layers of its new storage unit. A strange move given the company’s in-depth hardware and performance specifications.
Samsung des states the 970 EVO Plus operates much faster than the previous 64-layer version. Furthermore, the new flash supports Toggle 4.0 Interface, has a 256Gb die density, and works at 1.4 GT/z.

TurboWrite cache

The most exciting feature on the SSD is the TurboWrite Capacity. Let’s take a look:

The performance of the SSD unit varies according to how much data it lands in the TurboWrite cache. The TurboWrite cache is a small section that packs a faster SLC-programmed flash that boosts performance.

Samsung’s EVO Plus has a default TurboWrite cache, which will always work regarding the conditions. Additionally, it has an Intelligent Turbowrite region that varies its cache size according to the model and the free space available on the drive.

For example, the 1TB model has a 6GB TurboWrite capacity which gives an additional 36GB storage.

However, as the TurboWrite’s space is limited, transfers of large files will still land in the slower TLC flash.

Take note that the 2TB model will arrive in April 2019. Samsung hasn’t announced the cost of the said model.

Samsung’s 970 Evo PLus is almost the same as the previous 970 EVO. The 500GB and 1TB models go for $0.25-$0.26-per-GB. The 250GB model is actually expensive as it foes for $0.32-per-GB.

Regarding software, the new NVMe SSD has an optional drive download that improves its performance compared to Window’s default NVMe driver. It also ensures compatibility with Windows 7 and Windows 8.
