A901 2TB SLC Cache NVMe Gen 4x4 M.2 SSD - PCIe 4.0 Performance

Our review of the RiDATA A901 2TB NVMe SSD finds it best suited for gamers and creative professionals who need high sustained throughput and PS5-compatible capacity. The single biggest reason to buy is raw transfer speed: with PCIe Gen 4x4 and NVMe 1.4 it delivers read speeds up to 7,400 MB/s and write speeds up to 6,400 MB/s, which noticeably reduces load and export times compared with PCIe 3.0 drives. This review evaluates real-world fit, cooling design, and platform compatibility so you can decide if it belongs in your desktop, laptop or console upgrade.

Key Features

• Blazing sequential speeds: Read up to 7,400 MB/s and write up to 6,400 MB/s to accelerate game loads, file transfers and export tasks.
• PCIe Gen 4x4 with NVMe 1.4: The modern interface offers higher bandwidth and lower latency for demanding applications and future-proof builds.
• SLC cache and HMB: On-drive SLC caching with Host Memory Buffer support improves mixed workload performance and responsiveness during heavy multitasking.
• 3D Cooling Technology: The attachable copper foil graphite pad helps dissipate heat so speeds remain stable under sustained load.
• PS5 compatible capacity: 2TB capacity meets console storage requirements so users can add large game libraries without deleting content.
• Five-year warranty: A manufacturer warranty gives extra confidence in longevity for spirited daily use.

Who It's For

The A901 suits PC builders, gamers upgrading a PlayStation 5, and content creators needing fast scratch or project storage who want an M.2 2280 form factor and PCIe Gen 4x4 performance. Its 2TB size and cooling approach make it practical for long sessions and large game libraries.

Those with older systems limited to PCIe 3.0 will see reduced peak numbers but still gain a faster drive than many SATA or older NVMe models. If you need enterprise-grade endurance metrics or specialized power-loss protection, look to datacenter-class SSDs instead.

Pros & Cons

Pros

• Very high sequential read/write rates improve loading and transfer times.
• SLC cache plus HMB enhances mixed-workload responsiveness.
• Attachable copper foil graphite cooling helps maintain sustained performance.
• 2TB capacity and PS5 compatibility simplify console storage upgrades.

Cons

• Peak PCIe Gen 4 speeds are hardware dependent and will be lower on PCIe 3.0 hosts.
• Drive lacks some enterprise features like explicit power-loss protection specified for datacenter use.

Frequently Asked Questions

Is this drive compatible with PS5?
Yes, the 2TB capacity and M.2 2280 form factor meet PS5 storage expansion requirements when installed with appropriate cooling.

Will I see the listed speeds on an older system?
Speeds are hardware dependent; on PCIe 3.0 systems peak numbers will be lower than the Gen 4 figures but real-world responsiveness still improves over SATA or older NVMe drives.

Does the drive include thermal management?
The A901 ships with an attachable copper foil graphite pad (3D Cooling Technology) to reduce temperature and help sustain performance under load.
