After the Samsung SSD 980 PRO from fall 2020, the Samsung SSD 980 will appear on the hardware market in spring 2021. The tasks between Samsung’s two SSD series are clearly distributed. While the 980 PRO serves the demands of professional users, the 980 without any additions in the model name is primarily aimed at newcomers to the world of NVMe SSD drives.

Overview of the new features and innovations
The Samsung SSD 980 and the Samsung SSD 980 PRO each shine with special innovations. On the one hand, the 980 without PRO is the first drive from Samsung that doesn’t use the internal DRAM cache memory. Instead, the manufacturer relies on the HMB technology (Host Memory Buffer), which gives the SSD direct access to the system memory. On the other hand, the 980 with PRO is Samsung’s first PRO drive with Triple Level Cell NAND (TLC), which can store up to 3 bits per cell.
Performance and interface comparison
One difference between the Samsung SSD 980 PRO and the Samsung SSD 980 that is significant for performance is found in the interface used. Although both NVMe SSD drives conform to the M.2 2280 plug-in card format, the PRO variant is connected to the system via fourth-generation PCI Express. The more modern interface enables maximum read speeds of up to 7,000 MB/s compared to 3,500 MB/s of the Samsung SSD 980. The Samsung SSD 980 PRO is also clearly ahead in write with 5,100 MB/s compared to 3,000 MB/s.
Differences in warranty and configuration
Both the Samsung SSD 980 and the Samsung SSD 980 PRO use TurboWrite technology for write performance acceleration. The SLC cache buffer area of the former has been increased considerably in view of the missing DRAM. The manufacturer’s warranty of 5 years is pleasantly long for both SSD series and the TBW values are equally generous. The Samsung SSD 980 and the Samsung SSD 980 PRO overlap in capacities from 250 GB to 1 TB, the latter additionally offers a 2 TB variant.

Conclusion SSD comparison – Samsung SSD 980 and Samsung SSD 980 PRO differences
Purely reduced to the performance rates, the Samsung SSD 980 PRO is clearly ahead in comparison to the Samsung SSD 980, as expected. Whether on a PCIe 4.0 or a PCIe 3.0 port and even without the acceleration via TurboWrite, the NVMe SSD drive with the PRO in the model name is always faster. However, the higher performance, which rather only professional users benefit from, also means significantly higher costs per gigabyte. Therefore, every prospective buyer should individually check whether the Samsung SSD 980 could be the better, because cheaper, solution for him.

What is the difference between the 980 PRO 2tb models MZ-V8P2T0B/AM and MZ-V8P2T0BW?
Hello Gordon Laroussini,
as I see it, there are no technical differences between models MZ-V8P2T0B/AM and MZ-V8P2T0BW. Those are simply different model codes for the american and global markets.
