Capacity and interface

The SanDisk SN8100 is an 8TB internal solid-state drive that connects through a PCI-Express 5.0 x4 NVMe interface in the M.2 2280 form factor. It is aimed at gamers and content creators who need high-capacity, high-speed storage for large project files and modern game libraries.

Sustained workload behaviour

A custom anodized aluminium heatsink enables up to 15x longer elevated performance under heavy workloads compared with the non-heatsink version. The drive delivers sequential reads up to 14900 MBps and writes up to 13200 MBps, with random performance reaching 2200000 read IOPS and 2400000 write IOPS.

Build and daily implications

The heatsink adds a height of 11.25 mm, width of 25 mm and depth of 80 mm, weighing 31.2 g, and provides silent fanless cooling with customizable RGB lighting. Endurance is rated at 4800 TBW with an MTTF of 1.75M hours, while operating temperatures span 0 °C to 85 °C.
