This article covers SANDISK Optimus GX PRO 4TB 850X NVMe SSD 内蔵ソリッドステートドライブ.

Overview

The SanDisk Optimus GX PRO 850X NVMe SSD in 4TB capacity is a high-performance PCIe 4.0 drive designed for gamers and creative professionals. With sequential read speeds up to 7,300MB/s and write speeds up to 6,600MB/s, it significantly reduces load times and accelerates data-intensive workflows. It supports Microsoft DirectStorage for next-gen gaming and includes TCG Opal encryption for data security. This drive uses SanDisk's BiCS TLC 3D NAND and nCache 4.0 technology to deliver consistent performance under heavy workloads.

Key Features

Up to 7,300MB/s sequential read: Leverages full PCIe Gen4 bandwidth for lightning-fast game and application loading, reducing wait times dramatically. Up to 6,600MB/s sequential write: Handles large file transfers and 4K video editing with ease, boosting creative productivity. SanDisk nCache 4.0 technology: Optimizes cache management for improved random read/write performance, ensuring smooth multitasking. Microsoft DirectStorage support: Enables faster asset streaming in compatible games, reducing stutter and load times for a seamless experience. * TCG Opal v2.01 encryption: Hardware-level data protection for business and sensitive data, providing peace of mind in case of loss or theft.

Compatibility Guide

The drive uses the M.2 2280 form factor and connects via PCIe 4.0 x4 interface. It is compatible with modern Intel (600-series and later) and AMD (AM5, B650, X670) motherboards. It also works as an internal storage expansion for PlayStation 5 (firmware update may be required). The drive is NVMe 1.4 compliant and can be used in PCIe 3.0 slots, but performance will be halved. Always check your motherboard's M.2 slot specifications before purchase.

Product Info

Released in late 2024, this 4TB SSD features SanDisk's BiCS TLC 3D NAND. It comes with a 5-year manufacturer warranty. The package includes only the SSD itself. It is available at major retailers and online stores such as .

Best Use Cases

Gamers: Ideal for those who want the fastest load times in DirectStorage-enabled titles. The 4TB capacity allows storing a large game library without worrying about space. Creators: Perfect for 4K/8K video editors, 3D artists, and photographers who work with large files. The high sequential speeds reduce rendering and transfer times. * Security-conscious professionals: The TCG Opal encryption makes it suitable for laptops or workstations containing sensitive data, protecting against unauthorized access.

Things to Consider

To achieve full performance, a PCIe 4.0 motherboard and CPU are required. On PCIe 3.0, read speeds drop to around 3,500MB/s. The 4TB model is relatively expensive, and its TBW rating is lower than the 8TB variant, so it is not ideal for heavy write workloads like database servers. Sustained high-load writes can cause thermal throttling; using a motherboard with a built-in M.2 heatsink or adding an aftermarket heatsink is recommended.
