SanDisk Optimus GX 7100 1TB PCIe 4.0 NVMe M.2 2280 Internal SSD

SANDISK Optimus™ GX 7100 PCIe® 4.0 NVMe™ SSD, 1TB, Read 7,250MB/s Write 6,900MB/s, 5 Yr Warranty

The SanDisk Optimus GX 7100 1TB PCIe 4.0 NVMe M.2 SSD delivers sequential read speeds of up to 7,250 MB/s and sequential writes of up to 6,900 MB/s using an energy-efficient DRAM-less design. This drive combines high-speed Gen4 throughput with low power consumption to optimise performance in compact computing environments.

Built for high-speed gaming and compact system upgrades

Designed for modern workloads, this M.2 2280 drive provides the fast load times and rapid file transfers required by gamers and content creators. By utilising the PCIe 4.0 x4 interface and NVMe 2.0 protocol, it minimises data bottlenecks during heavy read and write operations. The drive delivers up to 1,000,000 IOPS random read and 1,400,000 IOPS random write performance, which translates to responsive multitasking, quick boot times, and rapid level loading in modern gaming titles. This allows you to load expansive game maps or import large media libraries without experiencing system stutter.

Maximising PCIe 4.0 throughput with Polaris 3 and BiCS TLC NAND

At the core of the drive is the SanDisk Polaris 3 controller paired with 8th Gen SanDisk BiCS TLC 3D CBA NAND. This combination ensures high-speed data processing without the physical space or power requirements of a dedicated DRAM chip. Instead, the drive employs Host Memory Buffer (HMB) technology, which leverages a small portion of your system's RAM to manage the lookup tables. This architectural choice maintains high burst speeds and consistent performance during daily computing tasks, file copying, and gaming sessions, delivering high-tier Gen4 performance while keeping production costs and power consumption low.

Low power draw and cool operation for slim laptops

Physical dimensions and thermal efficiency make this drive highly suitable for portable devices. Measuring just 2.38 mm thick and weighing 5.8 g, the single-sided M.2 2280 S3-M form factor fits easily into ultra-thin notebooks and small-form-factor desktop PCs. It operates with an active power consumption of 3.4 W during reads and 3.7 W during writes, dropping to a mere 5 mW when idle. This low power draw helps preserve laptop battery life and reduces heat generation, allowing the drive to maintain high performance within its 0°C to 85°C operating temperature range without requiring a bulky heatsink.

Long-term reliability backed by 600 TBW endurance

Built to withstand demanding daily use, the drive features an endurance rating of 600 TBW (Terabytes Written) and a Mean Time Between Failures (MTBF) of 1,750,000 hours. Physical durability is reinforced by a maximum shock resistance of 1,500G at 0.5 ms half-sine, protecting your data against accidental bumps or drops during transport. This makes it a highly reliable option for laptops that are constantly on the move. Data security is managed via TCG Pyrite 2.01 encryption, and the drive is backed by a 5-Year Limited Warranty.
