WD_BLACK SN7100 2TB NVMe SSD
The WD_BLACK SN7100 is a 2TB M.2 2280 internal solid-state drive using a PCI-Express 4.0 x4 interface and NVMe protocol. It employs TLC 3D NAND and operates without a DRAM cache, relying on host memory buffer technology. The drive targets consumers who want high sequential throughput for gaming libraries and content creation workloads.
Dashboard software and power efficiency
The downloadable WD_BLACK Dashboard for Windows provides drive-health monitoring and firmware updates to maintain peak operation. Active power draw averages 95mW with a 4.5W maximum, while sleep power is 5mW. The manufacturer states up to 100% better power efficiency over the prior generation, extending battery life in laptops and handheld devices.
Suited for mobile gamers.
The 1200TBW endurance rating and 1,750,000-hour MTBF support heavy write cycles such as gameplay streaming and engine compiles. Random performance reaches 1,000,000 read IOPS and 1,400,000 write IOPS. Buyers needing a DRAM cache for sustained database or virtualization tasks should evaluate alternative drives.

Questions about this item
When will the 1200TB TBW rating on this SN7100 drive require replacement?
The 1200TB TBW rating indicates the total data you can write before the warranty endurance limit is reached; typical consumer workloads rarely approach this figure within the drive's usable lifespan.
Does the 4.5W maximum operating power of this PCIe 4.0 x4 NVMe SSD become the thermal limit during sustained heavy writes?
The 4.5W maximum operating power is the peak draw; sustained workloads may hit thermal throttling before the power ceiling, depending on your laptop or motherboard M.2 cooling solution.
How much heat and noise does the WDS200T4X0E produce when running all day at 95mW average active power?
At 95mW average active power and 5mW sleep, the drive generates minimal heat and zero audible noise; thermal output is managed by the host device's M.2 slot cooling.
