High sequential read speeds: Speeds of up to 5,500MB/s help reduce loading times for large files and supported applications.
Fast sequential writes: Write speeds of up to 5,000MB/s support saving large projects, transferring media, and installing software.
Responsive application access: NVMe technology supports fast access to stored data and helps improve overall system responsiveness.
Efficient large-file handling: Suitable for moving extensive photo collections, high-resolution video files, and large project folders.
Random-access performance: High random IOPS ratings support workloads involving numerous smaller data requests.
System-dependent results: Actual performance varies according to the computer's PCIe generation, workload, thermal conditions, and system configuration.
Large 4TB capacity: Provides substantial room for games, software libraries, work documents, media collections, and backups.
Creative project storage: Suitable for maintaining large photo libraries, video assets, design files, and other professional content.
Application installation: Offers space for multiple large applications and supported games.
File organisation: Allows users to organise work projects and personal files on a single internal drive.
Operating system support: Can be used as a primary drive or secondary storage device on a compatible system.
Usable capacity: The available space displayed by an operating system may be lower than 4TB because of capacity measurement conventions, formatting, and system requirements.
PCIe Gen4 x4 interface: Uses four PCIe lanes to support high-bandwidth storage communication.
NVMe protocol: Optimised for fast communication between storage devices and compatible computer systems.
M.2 2280 design: Uses a compact 22mm-wide, 80mm-long module commonly supported by modern desktops and laptops.
Compatible PCIe systems: Can operate in compatible systems that support NVMe storage, although maximum speed depends on the host interface.
Platform considerations: Installing a Gen4 SSD in a system with an older supported PCIe generation may reduce achievable transfer speeds.
Thermal management: Adequate cooling may help maintain consistent performance during sustained workloads.
Game storage: The 4TB capacity accommodates a large collection of modern games and downloadable content.
Faster loading: High read speeds can help reduce loading times compared with many older storage devices.
Game library management: Provides room for multiple large installations without frequent uninstallation.
System responsiveness: Supports fast access to game assets and other stored resources.
Upgrade flexibility: Suitable as a primary game drive or an additional storage drive in compatible desktop systems.
Performance expectations: Game frame rates depend primarily on other system components; an SSD mainly improves storage-related loading and responsiveness.
Video editing: Provides substantial space for footage, media assets, project files, and exports.
Photography: Suitable for large image libraries, RAW photo collections, and editing applications.
Graphic design: Offers room for design software, project assets, and high-resolution files.

Multitasking: Helps maintain responsive storage access when working with multiple applications and large datasets.
Desktop computers: Compatible with motherboards that provide an appropriate M.2 PCIe NVMe slot.
Laptop upgrades: Suitable for compatible laptops that support M.2 2280 NVMe drives and the required drive capacity.
PCIe compatibility: Maximum performance requires a compatible PCIe Gen4 x4 interface.
Operating system installation: Can serve as a primary boot drive when supported by the computer and operating system.
Secondary storage: Can be installed alongside another storage drive where the system has an available compatible slot.
BIOS and operating system setup: A newly installed drive may need to be detected, initialised, partitioned, or formatted before use.
Physical fit: Check the M.2 slot specification, available clearance, mounting screw, and any required thermal solution before installation.
1,200TBW endurance: The rated endurance represents the specified total amount of data written over the drive's rated service life.
Solid-state construction: Uses NAND flash storage without the moving mechanical parts found in conventional hard disk drives.
Drive health monitoring: Compatible monitoring software can help users check drive status, capacity, and firmware information.
Temperature management: Operating within the specified temperature range helps support reliable operation.
Data protection: Regular backups remain important because solid-state drives can still fail or suffer data loss.
Workload considerations: QLC NAND provides high-capacity storage, while sustained write performance may vary with workload and available caching.
