Western Digital introduced its WD_BLACK SN7100 NVMe SSD series last November. The company says these drives use its newest TLC 3D NAND technology. These fresh SSDs run at speeds reaching 7,250 MB/s for reading and 6,900 MB/s for writing on the 1 and 2 TB sizes. This means they perform about 35% better than earlier models.
The official announcements never directly called the SN7100 a replacement for the popular SN770 from 2022. Yet the recent positive review by W1zzard of the 2 TB version makes several comparisons between these two product lines. Western Digital hinted at a larger storage option when they first talked about these drives last year.
Based on updated listings, a new 4 TB model of the WD_BLACK SN7100 will hit stores very soon. This breaks past the 2 TB limit that existed with the older SN770 family. Looking up the product code "WDS400T4X0E-00CJA0" shows a March 2025 data sheet. The SanDisk UK shop already takes early orders at £255.99, roughly $332 in US dollars.
The store page says buyers can expect their drives "within 1 week." Western Digital specs highlight the impressive 2400 TBW endurance rating for the 4 TB version. The smaller 1 TB and 2 TB models actually beat it slightly in speed tests. TechPowerUp gave the 2 TB SN7100 an "Editor's Choice" award in their review but mentioned they wanted a bigger capacity option. We might see this 4 TB drive tested at W1zz headquarters soon.
