Fast PCIe 4.0 Performance

The Optimus GX 7100 uses a PCIe 4.0 x4 interface to deliver substantially higher bandwidth than SATA-based storage. When installed in a compatible PCIe 4.0 system, the 500GB model can achieve sequential read speeds of up to 6,800MB/s and sequential write speeds of up to 5,800MB/s.

This performance helps reduce application loading times, accelerate file transfers and improve responsiveness during gaming and productivity workloads. Actual performance varies according to the host device, workload, firmware, drive capacity and operating conditions.

Up to 6,800MB/s Sequential Read

Sequential read performance of up to 6,800MB/s enables rapid access to large game files, applications and media. Faster storage access can help shorten game loading times and improve overall system responsiveness compared with slower storage technologies.

Up to 5,800MB/s Sequential Write

The 500GB Optimus GX 7100 provides sequential write speeds of up to 5,800MB/s, supporting fast installation, file-transfer and creative-workflow performance.

The performance figures are specific to the 500GB model. The higher-capacity Optimus GX 7100 variants have different manufacturer-rated performance specifications.

Strong Random Performance

Random performance reaches up to 760,000 read IOPS and 1.2 million write IOPS. High random I/O performance helps improve responsiveness when the operating system, applications and games need to access many smaller files simultaneously.

SanDisk TLC 3D CBA NAND

The Optimus GX 7100 uses SanDisk TLC 3D CBA NAND based on the company's 8th-generation BiCS flash technology. TLC NAND provides a balance of performance, endurance and storage density for demanding consumer workloads.

The architecture allows SanDisk to deliver high PCIe 4.0 speeds in the compact M.2 2280 form factor.

SanDisk nCache 4.0 Technology

Integrated SanDisk nCache 4.0 technology uses SLC caching to help accelerate common write operations and support responsive performance during gaming, multitasking and large file transfers.

Host Memory Buffer

The SSD uses Host Memory Buffer technology, allowing the drive controller to use a small portion of compatible system memory for management functions instead of incorporating a dedicated onboard DRAM cache.

This contributes to an efficient drive design while maintaining strong PCIe NVMe performance.

Designed for Gaming

SanDisk positions the Optimus GX 7100 as a gaming-focused NVMe SSD. Its high sequential and random performance helps reduce loading delays and improve responsiveness in modern PC games and other demanding applications.

The drive is also suitable for creative and productivity workloads where fast storage access is beneficial.

Microsoft DirectStorage Support

The PCIe NVMe architecture helps prepare compatible PCs for games that support Microsoft DirectStorage. DirectStorage can allow supported games to load assets more efficiently from NVMe storage when used with compatible hardware, operating systems and software.

Power-Efficient Architecture

The 500GB model is rated at approximately 3.4W average active power during sequential reads and approximately 3.5W during sequential writes under SanDisk's specified test conditions.

Sleep power is rated at approximately 5mW, helping reduce unnecessary power consumption when the drive is inactive.

300 TBW Endurance

The 500GB Optimus GX 7100 has an endurance rating of 300 TBW, calculated using the JEDEC client workload standard. This means the drive is designed to accommodate substantial everyday gaming, productivity and file-transfer workloads over its service life.

Up to 1.75 Million Hours MTTF

SanDisk specifies an estimated Mean Time To Failure of up to 1.75 million hours based on its internal reliability testing methodology.

MTTF is a statistical reliability measurement for a product population and does not represent the expected lifetime or warranty duration of an individual SSD.

Compact M.2 2280 Design

The drive measures approximately 80 × 22 × 2.38 mm and weighs approximately 5.8 g, allowing it to fit compatible desktop PCs, notebooks and other systems with an M.2 2280 NVMe slot.

The SSD does not include an integrated heatsink, so system cooling requirements should be considered when installing it in high-performance environments.

Backward PCIe Compatibility

SanDisk specifies the PCIe 4.0 x4 interface as backward compatible with supported PCIe 3.0 and PCIe 2.0 lane configurations. Performance will be limited by the capabilities and available bandwidth of the host interface when connected to an earlier-generation PCIe slot.

SanDisk Dashboard

SanDisk Dashboard software for Windows can be downloaded separately to monitor supported drive information, keep firmware updated and enable supported features such as Game Mode.

Acronis True Image for SanDisk

The drive supports Acronis True Image for SanDisk software to assist with migration from an existing storage device. Download, installation, administrative privileges and applicable licensing or redemption conditions apply.

Security Features

The Optimus GX 7100 supports TCG Pyrite 2.01 and ATA Security passthrough over NVMe, providing compatible systems and management tools with supported drive-level security functionality.

Shock and Vibration Resistance

With no moving mechanical components, the SSD is designed for the vibration and shock encountered in compatible desktop and mobile computing environments. SanDisk specifies operating vibration resistance of 5 gRMS and shock resistance of up to 1,500G at 0.5 ms half-sine under defined test conditions.
