Samsung 970 EVO 2TB M.2 NVMe PCIe SSD Review (Page 1)

Samsung 970 EVO 2TB M.2 NVMe PCIe SSD Review

Samsung's 970 EVO 2TB is the first SSD we've tested that comes armed with 512Gbit (64GB per die) flash. How does it perform?

Almost two years ago, Samsung brought to market the world's first 2TB M.2 NVMe SSD, the 960 Pro 2TB. The exotic MLC powered 2TB 960 Pro came with eye-popping $1,300 price tag that placed out of reach for the typical consumer. Now, Samsung is back with another 2TB single-sided M.2 NVMe SSD and this time it's much more affordable. Enter the 970 EVO 2TB. Like the 960 Pro 2TB, Samsung's 970 EVO is a desirable single sided design but thanks to advances in 3-bit flash technology, the cost of ownership isn't nearly as steep.

When the 2TB 960 Pro emerged on the scene, Samsung's own 256Gbit flash was the highest density in production. The 960 Pro employed four 512GB flash packages, each composed of sixteen 256Gbit (32GB) die. With 512GB flash packages at the top of the food chain, Samsung had to fit four flash packages, DRAM and a controller on one side of the 2TB 960 Pro's PCB to achieve a single-sided design. Not easy to do.

Samsung's 2TB 970 EVO is the first consumer NVMe SSD to arrive armed with 512Gbit V-NAND. The density afforded by 512Gbit flash allows Samsung to fit 1024GB (1TB) of storage on a single sixteen die flash package. With 1TB of V-NAND on a single flash package, a single-sided 2TB M.2 SSD with a conventional two-package flash array is possible.

Having already tested the 1TB 970 EVO, which earned an editor's choice award, we have high expectations for the 2TB model. However, we also know that with different flash (256Gbit vs. 512Gbit), there may be some performance differences as well.

The 970 EVO is powered by Samsung's "Phoenix" NVMe controller. Phoenix, like its predecessor "Polaris" is a 5-core ARM-based processor. One core is dedicated to host communication and the other four to the drives NAND array. Samsung's Phoenix controller features increased core-clock speeds and enhanced thermal capabilities over previous generations.

With Samsung's potent Phoenix controller powering a 64-layer V-NAND flash array, the 970 EVO delivers performance that is far better than the 960 EVO. The 970 EVO provides up to 32% faster sequential speeds and up to 36% faster random speeds than its predecessor.

Samsung's 64-layer 3-bit V-NAND is faster and more enduring than the previous generation 3-bit V-NAND. Material improvements and lower voltage requirements for cell programming have increased the 970 EVO's endurance rating by 50% at each capacity point over the 960 EVO. Additionally, Samsung has increased the EVO's warranty period from 3-years to 5-years.

Like the 960 EVO, the 970 EVO employs a copper infused label on the back of the drive's PCB for enhanced heat dissipation. In addition, the Phoenix controller is nickel plated allowing it to dissipate heat faster which helps maintain peak performance better than ever before.

The 970 EVO's improved thermal performance delays the trigger point of Samsung's Dynamic Thermal Guard (DTG) by 14 seconds in comparison to the 960 EVO.

Higher throughput and DTG triggering 14 seconds later than before allows the 970 EVO to transfer approximately 26% (approximately 32GB) more sequentially written data before thermal throttling is induced.

Samsung's 2TB 970 EVO is more about capacity than anything else. 2TB of super-fast NVMe storage on a tiny single-sided M.2 x 2280 SDD is very appealing and unique in the world of storage. As it stands, the 2TB 970 EVO has no direct competitor, because so far no one else has delivered a similarly configured M.2 SSD. Others are coming, but Samsung's 2TB 970 EVO is the first.

Let's get into the review and see how the world's first NVMe SSD equipped with 512Gbit flash performs.
