XPG GAMMIX S70 Blade 4TB PCIe Gen4 M.2 SSD - High-Speed PS5 Storage

In this review the XPG GAMMIX S70 Blade 4TB is evaluated as a high-capacity, high-speed internal SSD aimed at gamers and creators who need extensive storage and fast load times. The reviewer finds the single biggest reason to buy is the combination of large 4TB capacity and PCIe Gen4 performance, which delivers significantly faster sequential reads and writes on compatible PCs and a practical expansion for PlayStation 5 owners when firmware requirements are met. Installation is straightforward for M.2 2280 slots and the drive is backed by a 5-year limited warranty.

Key Features

• PCIe Gen4 NVMe 1.4 interface: Enables very high sequential transfer rates when paired with a motherboard or console that supports PCIe 4.0.
• Top sequential speeds on PC: Up to 7400 MB/s read and 6800 MB/s write in ADATA lab tests, which reduces loading and file transfer times for large projects.
• PS5 compatibility: Works with PS5 when the console firmware is 21.02-04.00.00.42 or higher and provides much more storage for games than the internal drive.
• M.2 2280 form factor: Fits directly into standard M.2 slots on compatible motherboards without requiring an external enclosure.
• Backward compatible with PCIe 3.0: Will operate in older systems with reduced performance, making it usable across multiple machines.
• Five-year limited warranty: Offers longer-term coverage that reflects confidence in component quality.

Who It's For

The GAMMIX S70 Blade 4TB is best for PC gamers, content creators, and PS5 owners who need a large amount of fast internal storage and who have a motherboard or console that supports PCIe 4.0. It suits users who routinely move large game libraries or raw media files and who benefit from faster sequential read and write performance for loading, editing, and transfers.

It is less suitable for people who only have a PCIe 3.0 system and do not plan to upgrade, since speeds will be limited to PCIe 3.0 ceilings. Also, those who require an external portable drive or an enclosure-compatible solution should look elsewhere because the drive is designed for direct M.2 installation.

Pros & Cons

Pros

• Very large 4TB capacity that triples typical console storage and holds extensive PC game or media libraries.
• Exceptional sequential performance on PCIe 4.0 platforms for faster load times and file transfers.
• Simple M.2 installation and broad backward compatibility with PCIe 3.0 motherboards.
• Five-year limited warranty provides added ownership assurance.

Cons

• Heat management can be mixed in real use; included heatsink helps but some users report it may trap heat in certain enclosures.
• To work on PS5 requires a specific console firmware version, so users must update before use.

Our Verdict

The XPG GAMMIX S70 Blade 4TB is a strong choice for anyone who needs lots of internal storage and wants the benefits of PCIe Gen4 speeds for gaming or media work. It represents good value for the capacity and performance, but potential buyers should confirm PCIe 4.0 support or PS5 firmware readiness and consider their thermal setup since heat behavior can vary.

Frequently Asked Questions

Will this drive work in a PS5?
Yes, it will work in a PS5 provided the console is updated to firmware 21.02-04.00.00.42 or later and the physical installation fits the console expansion bay.

Do I get PCIe 4.0 speeds on any motherboard?
You only get full PCIe 4.0 speeds on motherboards that support PCIe 4.0; in a PCIe 3.0 slot the drive will run at reduced maximums around PCIe 3.0 limits.

Is an external enclosure supported?
The drive is designed for direct M.2 installation on a motherboard and may not work or may be thermally compromised in some external enclosures.
