SanDisk Optimus GX PRO 850X 2TB PCIe 4.0 NVMe M.2 2280 SSD

SANDISK Optimus™ GX PRO 850X PCIe® 4.0 NVMe™ SSD, 2TB, Read 7,300MB/s Write 6,600MB/s, 5 Yr Warranty

The SanDisk Optimus GX PRO 850X 2TB PCIe 4.0 NVMe M.2 SSD delivers sequential read speeds of up to 7,300 MB/s and write speeds of up to 6,600 MB/s to accelerate system boot times and file transfers. This M.2 2280 drive leverages a PCIe Gen4 x4 interface and NVMe 1.4 protocol to maximise throughput for demanding gaming and creative workloads.

High-speed PCIe Gen4 performance for demanding workloads

With random read speeds reaching up to 1,200,000 IOPS and random write speeds up to 1,100,000 IOPS, this drive handles complex multitasking and rapid asset loading with ease. The high IOPS ratings ensure that small file transfers, database operations, and operating system background tasks occur almost instantaneously, reducing latency during intensive computing sessions. This makes the drive highly responsive when loading massive game levels or scrubbing through multi-stream 4K video timelines.

Optimised load times with nCache 4.0 and DirectStorage

This drive utilizes a power-efficient DRAM-less architecture paired with nCache 4.0 technology to maintain high performance during sustained write operations. The nCache 4.0 algorithm intelligently manages write caching to handle large file transfers without sudden performance drops. It also supports Microsoft DirectStorage, which allows compatible graphics cards to communicate directly with the SSD, bypassing the CPU to drastically reduce game loading screens and texture streaming latency.

Reliable TLC 3D NAND with 1200 TBW endurance

Built with SanDisk BiCS TLC 3D NAND, the drive is rated for an endurance of 1200 TBW (Terabytes Written) and a Mean Time To Failure (MTTF) of 1.75 million hours, ensuring long-term data integrity. This high write endurance makes it an excellent choice for write-heavy environments, such as scratch disks for video editing or local database hosting. It operates reliably across a wide temperature range of 0°C to 85°C, making it suitable for compact system builds where airflow may be restricted.

Hardware-level data protection and a five-year warranty

For users handling sensitive information, the drive features built-in TCG Opal v2.01 hardware encryption to protect data without compromising system speed. Weighing just 7.5 grams and measuring 80 mm x 22 mm x 2.38 mm, this slim M.2 2280 S3-M form factor fits easily into compatible motherboard slots and thin-profile laptops without adding unnecessary bulk. The drive is backed by a 5-year limited warranty, offering peace of mind for your storage infrastructure.
