Model 8TB

  • PCIe 5.0 x4 NVMe delivers up to 14,900 MB/s sequential read for fast load times
  • 8TB capacity stores large game libraries and AI models on a single M.2 2280 drive
  • 8GB DRAM cache sustains up to 13,200 MB/s sequential write during heavy content creation
  • 4,800 TBW endurance and 1,750,000-hour MTTF protect data through years of intensive use
  • Active power draw of 7.1 W read and 7.3 W write keeps thermals manageable without a heatsink

Capacity and audience

The SanDisk WDS800T1X0M-00CMT0 is an 8TB internal SSD built for consumer workloads. It fits the M.2 2280 form factor and connects through a PCI-Express 5.0 x4 interface using the NVMe protocol. The drive targets gaming, content creation and AI model loading.

Deciding specification

The single figure that determines suitability is the 4800TB terabytes written endurance rating. This number defines how much data can be written over the drive's warranted life. A workload that exceeds this limit will require a higher-endurance alternative.

Sustained load behaviour

Under continuous operation the drive draws 7.1W during reads and 7.3W during writes while maintaining sequential speeds up to 14900 MBps read and 13200 MBps write. Operating temperature stays within 0°C to 85°C without a heatsink. The 8GB DRAM cache and nCache 4.0 technology help sustain random performance up to 2,200,000 read IOPS and 2,400,000 write IOPS.

Questions about this item

What does the 14900 MBps sequential read figure mean when the drive is installed in a system?

That is the peak sequential read speed the 8TB WD_BLACK SN8100 can reach over a PCI-Express 5.0 x4 link; real-world throughput will depend on the motherboard slot, cooling and workload.

How does the PCI-Express 5.0 x4 interface limit performance in practice?

The x4 lane width caps the theoretical bandwidth at the PCIe 5.0 rate, so the drive cannot exceed the 14900 MBps read and 13200 MBps write ceilings even if the controller could go faster.

What physical space and mounting does the M.2 2280 form factor require?

It needs an M.2 slot that accepts 2280-length modules (80 mm long) and a motherboard standoff at the 80 mm position; the drive ships without a heatsink, so clearance above the PCB is minimal.
