Similarities in format and interface
The Samsung SSD 870 EVO and the Samsung SSD 860 PRO are similar in many aspects. Both drives are 2.5-inch SSD hard drives, which correspond to the standard in their outer dimensions with a height of just under 7 millimeters. As for the connection, Samsung relies on the SATA 6 Gb/s interface, which is widely used in desktop computers and notebooks, for both the 860 PRO and the 870 EVO, as is usual in this form factor.

Differences in flash memory and technology
One major difference between the Samsung SSD 860 PRO and the Samsung SSD 870 EVO is found in the type of flash memory used. A 3-bit TLC NAND is installed in the EVO SSD, which has long been established on the market thanks to low production costs and high reliability at the same time. In contrast, a 2-bit MLC memory is used in the PRO SSD, which is considerably more expensive, but promises a better performance even under permanent load.
Comparison of performance and speed
The performance of the Samsung SSD 870 EVO and the Samsung SSD 860 PRO is on par with 560 MB/s in sequential read and 530 MB/s in sequential write.
The performance in random operations is also very similar. However, due to the different flash memory type, the 860 PRO does not require TurboWrite technology as an SLC cache for write acceleration compared to the 870 EVO.
Similarities in storage size and warranty
The Samsung SSD 870 EVO and Samsung SSD 860 PRO offer a choice of storage capacities between the entry-level-friendly 250 GB and 256 GB, respectively, and the hard drive replacement-worthy 4 TB. The manufacturer’s warranty in both cases is a very customer-oriented 5 years, whereby twice the amount of data can be written to the PRO SSD without a claim loss during this period.

Conclusion SSD comparison – Samsung SSD 860 PRO and Samsung SSD 870 EVO
The Samsung SSD 860 PRO and the Samsung SSD 870 EVO are very similar, but at the same time have earned their right to exist due to their different orientations. The EVO SSD with its attractive price-performance ratio is the all-round solution for a broad audience of normal users.
The PRO SSD, on the other hand, is explicitly aimed at enthusiasts and professionals who have a larger budget at their disposal and do not want to make any compromises in terms of performance, even in continuous operation.

Reddit — Dive into anything
In October 2020 during the 870 QVO launch, Samsung Insights—Samsung’s official business marketing newsletter—had spilled the beans on the upcoming 870 EVO and 870 PRO in an article titled «Samsung’s 870 SATA will change how we use SSDs»,
The company’s newest offering — the Samsung 870 QVO — takes the SSD line to the next level, hitting a top capacity of 8TB while achieving a 530MB/s, 560MB/s read/write speed.
The 870 series also includes EVO and PRO versions of the drive with storage capacities of 4TB each and a new controller, the Samsung MKX SATA SSD controller.
…
In addition, users who want to integrate a new 870 PRO into existing SSD storage offerings can use the Samsung Magician storage management application, which comes with the drive. The Magician software makes it easier to work with the 870 PRO, whether the user is maintaining the drive’s health, boosting performance or updating firmware.
…
Of course, the real test of any storage offering is its capabilities and the variety of use cases it supports. The 870 PRO helps gaming enthusiasts boot up scenes and stages more quickly, and it also makes navigating menus and moving from game to game quicker and easier
They link to the 870 QVO press release, which mentions nothing about these presumably TLC & MLC variants. The 870 PRO is only mentioned on Samsung Insights.
The 870 EVO, however, already has product pages up on both Samsung & retailers like Office Depot.

Is it 96L V-NAND or 128L V-NAND? I do wonder if it’s those mysterious «250 GB SATA SSDs» promised during the 128L launch in August 2019,
Samsung Electronics, the world leader in advanced memory technology, today [August 6th, 2019] announced that it has begun mass producing 250-gigabyte (GB) SATA solid state drive (SSD) that integrates the company’s sixth-generation (1xx-layer) 256-gigabit (Gb) three-bit V-NAND for global PC OEMs.
By launching a new generation of V-NAND in just 13 months, Samsung has reduced the mass production cycle by four months while securing the industry’s highest performance, power efficiency and manufacturing productivity.
Samsung SSD 870 EVO vs Samsung SSD 860 EVO – SSD comparison
Samsung SSD 860 EVO has been one of the most popular SSD drives for several years now.

Form factor and memory size comparison
The Samsung SSD 860 EVO offers a wide range of formats and connections. The drive is available in a 2.5-inch form factor, as a plug-in M.2 2280 card, or in the mSATA standard. The new Samsung SSD 870 EVO, on the other hand, is only available as a 2.5-inch SSD. In terms of interface and features, however, you won’t find any differences. Both EVO series use the SATA 6Gb/s interface, and storage capacities range from 250GB to 4TB (4,000GB).

Differences in performance and speed
The performance of the Samsung SSD 870 EVO is only marginally improved compared to the Samsung SSD 860 EVO, which is understandable given the limitation of the SATA III interface.
Sequential read and write numbers are now slightly closer to the technically possible limits of 10 MB/s each — 560 MB/s and 530 MB/s, respectively. Samsung uses TurboWrite technology in the 870 EVO, as it did in the 860 EVO, to speed up write speeds while maintaining the same buffer size across generations.
Warranty and Specification Similarities
In terms of warranty, buyers won’t have to compromise on the Samsung SSD 870 EVO versus the Samsung SSD 860 EVO. The warranty period of 5 years and the amount of data that can be recorded during this time without loss of rights are identical. In both EVO series, Samsung installs 3-bit TLC flash memory with a theoretical single cell life of 1.5 million hours. The power consumption of the 870 EVO is lower in read/write and sleep mode compared to the 860 EVO.
