ADATA Legend 860 1000GB NVMe Gen4 SSD

Interface & Form Factor: M.2 2280 (80 × 22 mm) in the NVMe format using PCIe Gen 4 ×4 — meaning it plugs directly into modern motherboards and supports high bandwidth data transfer.

Top Speeds: On the 1 TB variant, ADATA quotes up to ~6,000 MB/s sequential read and ~4,000–5,000 MB/s sequential write. That means huge file loads, fast boot-times and smooth operation for demanding apps.

Storage Capacity: With 1 TB of space you get ample room for OS, programs, games, media libraries or project files — balancing performance and capacity.

Advanced caching & error-correction: It uses SLC cache algorithm, Host Memory Buffer (HMB) support, and LDPC (Low-Density Parity-Check) error correction technology — which contributes to consistent performance and data integrity.

Robust durability: MTBF (Mean Time Between Failures) is stated at 2,000,000 hours. On the datasheet the TBW (Total Bytes Written) for the 1 TB model is ~320 TB — meaning it’s rated to handle heavy workloads.

Backward compatibility / PS5 support: Although built for PCIe Gen 4, it is backward compatible with PCIe Gen 3 platforms. Moreover, it’s explicitly supported or marketed for use in console expansion (e.g., for the PlayStation 5) — meaning it fits into gaming-oriented setups.

Thermal & form considerations: The version with a heatsink has dimensions ~80 × 22 × 3.13 mm and weight ~9.5 g; without a heatsink ~2.15 mm thick. That makes it suitable for most desktops/laptops/console slots.
