SanDisk Optimus GX PRO 8100 1TB M.2 2280 PCIe 5.0 x4 NVMe 2.0 internal SSD SDSP82100TAN-000E0

Target workloads

The SanDisk Optimus GX PRO 8100 is a 1 TB internal SSD built for professionals, creators and gamers who need PCIe 5.0 x4 NVMe 2.0 bandwidth. 3D NAND TLC flash and the nCache 4.0 layer deliver sequential reads up to 14900 MBps and writes up to 11000 MBps. Random performance reaches 1600000 read IOPS and 2400000 write IOPS for responsive AI workloads and large game libraries.

Upgrade path

Moving from a PCIe 4.0 drive yields more than double the power efficiency at 6.2 W active read and 6.1 W active write. The 600 TBW endurance rating and 1750000 hour MTBF make the jump worthwhile for sustained write intensive tasks such as video editing or model training. The M.2 2280-S3-M form factor fits existing slots without a heatsink.

Sustained behaviour

Without a heatsink the controller manages thermals up to the 85 °C operating limit, so extended sessions throttle later than on Gen 4 designs. Idle power stays at 5 mW, keeping laptop battery drain low during background workloads. The 5.0 interface maintains consistent throughput across long transfers rather than peaking only in short bursts.
