Description
SanDisk Optimus™ GX 7100 PCIe® 4.0 NVMe™ SSD, 500GB, Read 6,800MB/s Write 5,800MB/s, 5 Yr Warranty
The SanDisk Optimus GX 7100 500GB NVMe PCIe 4.0 M.2 SSD delivers sequential read speeds of up to 6,800 MB/s and sequential write speeds of up to 5,800 MB/s using the WD Polaris 3 controller. This compact M.2 2280 S3-M drive provides a responsive storage solution for operating systems, demanding applications, and modern gaming libraries.
High-speed PCIe Gen4 performance for responsive system boot-ups
Operating on the PCIe 4.0 x4 interface and utilising the NVMe 2.0 protocol, this drive significantly reduces loading times compared to older SATA-based storage. It achieves random read speeds of up to 760,000 IOPS and random write speeds of up to 1,200,000 IOPS, ensuring rapid file access and smooth multitasking. The NVMe 2.0 protocol enhances communication efficiency between the drive and your CPU, reducing overhead and latency for real-time applications. Whether loading large game files, exporting media projects, or handling complex data sets, the high IOPS throughput keeps system responsiveness high under heavy workloads.
DRAM-less efficiency with Host Memory Buffer technology
The Optimus GX 7100 features a DRAM-less design that leverages Host Memory Buffer (HMB) technology. By utilising a small portion of your system's memory (RAM) to cache the translation table, the drive maintains high-speed performance without the cost or power consumption of a dedicated onboard DRAM chip. Combined with BiCS TLC 3D CBA NAND, this architecture ensures consistent write performance and reliable data retention across the entire 500GB capacity.
Low power draw for cooler, efficient operation
Engineered for thermal and power efficiency, this drive consumes just 3.4W during active read tasks and 3.5W during active write operations. When idle, the drive drops to an ultra-low sleep power state of 0.005W, making it highly suitable for laptops and small form factor builds where battery life and thermal management are critical. It operates reliably across a wide temperature range from 0°C to 85°C, withstanding non-operating temperatures from -40°C to 85°C.
Built for long-term endurance and data security
With an endurance rating of 300 TBW (Terabytes Written) and a Mean Time To Failure (MTTF) of 1.75 million hours, the drive is built to handle years of daily write cycles. Physical durability is reinforced by an operating shock resistance of 1500 G and vibration resistance up to 5 G. For data protection, the drive supports TCG Pyrite 2.01 encryption standards to help secure sensitive files against unauthorised access. A 5-year limited warranty provides long-term peace of mind, ensuring the drive remains a dependable component of your storage setup.
