With the release of the Plus series from Samsung, the 970 EVO has become super boosted. While the 970 EVO was already fast, it had a maximum capacity of 1 TB. The new Samsung 970 EVO Plus now has a 2 TB capacity.

Previously, 2 TB models were available for the 960 Pro and 970 EVO series. These models were based on the 96-layer TLC written NAND paired with a controller from Phoenix.

The current 970 EVO Plus memory chips come in four capacity choices – 250GB, 500GB, 1TB, and 2TB volumes. The Plus series uses the M.2 standard and 8cm form factor. Since the SSD uses the newest version of  the NVMe protocol, these chips require PCI-Express 3.0 with x4 lanes. The 2TB edition has double the endurance of the 1TB model at 1200 TB written vs 600 TBW. These models are capable of 3.5GB/s read output.

Non-Volatile Memory Express (NVMe) M.2 form factor has vertical NANA (V-NAND) technology. Storage technology is advancing at a rapid pace with performance numbers for the current crop of SSDs being nothing short of excellent. NAND flash memory is becoming cheaper over time.

The Phoenix controller is what powers the 970 M.2 product line. The weight advantage of the M.2 SSDs make them ideal for ultra light laptops or ultrabooks. They can be 10% of the weight of a similar 2.5 inch SSD. It is important to be aware of compatibility and usability issues with this form factor. It can only be used with modern motherboards that support the NVMe M.2 standard; that is to say – PCIe Gen 3.0 x4 lanes connected.

The tables show that the Samsung 970 EVO Plus 2TB model has sequential read speeds of 3500MB/s which is the same as the 250GB, 500GB and 1TB models. On the other hand, the sequential write speed of 3300MB/s is faster than the 250GB and the 500GB models but the same as the 1TB model.

The 970 Plus comes at a price as it is not the cheapest SSD available. Generally current pricing lists this product at approximately 25 cents per GB. It will not be the cheapest option for your computer but it will be among the fastest. The improves write performance may be worth it to many people especially videographers processing a lot of 4K video. Samsung has pushed the limits of this technology and garnered every last bit of performance possible out of the PCIe x4 Gen 3 standard.

As for longevity, the 970 plus has a 5 year warranty from Samsung. It is capable of 1200 TBW meaning if you write 100 GB per day to your SSD, that equates to 36 TB per year and the math works out to approximately 33 years of total usage time before expiry. This SSD should be future proof at least for any reasonable technology perspective. Costs for this technology are always coming down. It is possible to see these SSDs in the 10 cent per GB range in the near future. That would be quite a bargain considering the performance and quality that the 970 Plus series brings to the table.
