WD Black SN750 SE NVMe SSD vs WD Black SN850 NVMe SSD

Based on the numbers in the model’s name alone, the WD Black SN850 NVMe SSD should offer users more value compared to the WD Black SN750 SE NVMe SSD. What are the differences between the two drives from Western Digital? What advantages do the WD SN750 SE, which was introduced in the spring of 2021, and the WD SN850, which has been available since the fall of 2020, each throw into the balance?

Differences in performance and speed

Although both the WD Black SN850 NVMe SSD and the WD Black SN750 SE NVMe SSD are connected to the system via today’s latest PCI Express interface in the fourth generation, their performance values differ decisively. The read performance is 7,000 MB/s compared to 3,200 MB/s and 3,600 MB/s, respectively. For writing, the SN850 achieves between 4,100 MB/s and 5,300 MB/s, depending on the capacity, compared to 1,000 MB/s to 2,830 MB/s of the SN750 SE.

Comparison of features and dimensions

Another advantage of the WD Black SN850 NVMe SSD compared to the WD Black SN750 SE NVMe SSD is the ability to purchase the drive with a factory-installed heat sink for better temperature management. However, the dimensions increase as a result, especially in height, which makes installation in a laptop no longer possible. Otherwise, both SSDs from Western Digital correspond to the M.2 2280 form factor in length and width.

Parallels in capacities and warranty

The two SSD series are offered in storage sizes of 500 GB and 1,000 GB (1 TB). The WD Black SN750 SE NVMe SSD is also available in a smaller and thus cheaper variant with 250 GB. In contrast, the WD Black SN850 NVMe SSD is available with 2,000 GB (2 TB) for large storage space requirements when gaming or working. The warranty period of 5 years and the amount of data that can be written to the drive during that time are equally generous.

Conclusion SSD comparison – WD Black SN850 NVMe SSD and WD Black SN750 SE NVMe SSD differences

In operation on a platform with PCIe 4.0, the WD Black SN850 NVMe SSD outperforms the WD Black SN750 SE NVMe mercilessly. The read performance would equalize on a PCIe 3.0, but the former should still be better in write mode. Given the significantly higher speeds at a (currently) not too high price difference, the price-performance ratio of the WD SN850 seems much more attractive compared to the SD SN750 SE. If you want a pre-mounted cooler or a very high storage capacity, you cannot avoid Western Digital’s SN850 anyway. If you have a limited budget, the SN750 SE with 250 GB could be interesting after all.
