SanDisk Optimus 5100 4TB Internal SSD

The SanDisk Optimus 5100 is a 4TB internal solid state drive built for desktop and laptop upgrades. It uses QLC 3D CBA NAND and a PCI-Express 4.0 x4 interface with NVMe protocol. The drive suits users who need high-capacity storage for large media libraries or game installs. No DRAM cache is present, relying on SLC caching instead.

M.2 2280 form factor without heatsink

The drive adopts the standard M.2 2280 form factor measuring 22mm by 80mm and 2.38mm high. It weighs 5.7g and ships without a heatsink, so it fits directly into motherboard slots or laptop bays that accept single-sided modules. The PCI-Express 4.0 x4 edge connector provides the data and power path. Ensure your platform supports the length and keying before installation.

Thermals and power in daily use

Idle power draw is 4.5 mW while average active read and write power is 4.3W each. The operating temperature range spans 0°C to 85°C. With no integrated heatsink, thermal performance depends on airflow from the system or a motherboard shield. The drive is rated for 1200TB written and 1,750,000 hours MTBF, indicating endurance for heavy workloads.
