ADATA Legend 860 M.2 PCIe4x4 500GB SSD

Description

Genuine Mid-Range Gen 4 Performance

The Legend 860 is fully backward compatible with PCIe 3.0 platforms while delivering full PCIe Gen 4 x4 performance where the platform supports it. At 5,000MB/s read and 3,000MB/s write, the 500GB model sits well above the budget Gen 4 tier — providing a practical performance advantage for gaming, creative work, and multitasking that budget-tier alternatives at this capacity don’t match. The LEGEND 860 provides excellent output for mid-to-high-end productions such as film and television animation, machine learning, and product modelling, and makes a capable everyday drive for demanding desktop and laptop workloads.

PS5 Storage Expansion — Officially Compatible

The LEGEND 860 utilises a PCIe 4.0 transmission interface and can be installed in the PS5 as an expansion drive to alleviate PS5 storage insufficiency issues. It fits perfectly into the PS5’s drive slot and provides a smooth, no-lag gaming experience. The included heatsink satisfies Sony’s heatsink recommendation for M.2 expansion drives in the PS5, meaning no additional purchase is required.

SLC Cache, HMB, and LDPC ECC

The Legend 860 utilises an SLC cache algorithm and HMB (Host Memory Buffer) technology to take advantage of caching, and adopts LDPC (Low-Density Parity Check Code) error correction to ensure the accuracy of data transmission and file security. The SLC cache handles burst write workloads in faster single-level cell mode, while HMB borrows a portion of system RAM to supplement the DRAM-less controller — delivering near-DRAM-cache performance on Windows 10 and later without the cost and power draw of dedicated on-drive RAM.

Heatsink Included — Ready for PS5 and Demanding Desktops

The aluminium heatsink ships in the box and mounts directly to the drive. The integrated heatsink maintains optimal performance under high workloads, keeping temperatures in check during sustained transfers and gaming sessions. At 3.13mm total height with the heatsink fitted, it’s compatible with most desktop M.2 slots — verify clearance in compact SFF cases.

SSD Toolbox and S.M.A.R.T. Monitoring

SSD Toolbox ensures users have the latest firmware version for the best performance and employs S.M.A.R.T. to monitor the health and remaining lifespan of the drive, as well as the current operating temperature and storage capacity — allowing users to track SSD status at any time. A practical inclusion for a drive that will serve as primary storage in a gaming console or workstation over a 5-year warranty period.

5-Year Warranty and Strong Endurance

The 500GB Legend 860 carries a 160TBW endurance rating and a 2,000,000 hour MTBF, backed by a 5-year limited warranty. That’s nearly three times the TBW of the Crucial E100 480GB at a similar capacity, and the 5-year coverage matches the best warranty in this range. For a primary OS, games, and applications drive, 160TBW is a genuinely comfortable long-term figure.

ℹ️ PCIe Gen 4 slot recommended — full 5,000MB/s read performance requires a PCIe Gen 4 M.2 slot. The Legend 860 is backwards compatible with Gen 3 at approximately half the rated speeds — still a meaningful upgrade over any SATA drive.

ℹ️ 500GB-specific speeds — the 500GB model is rated at 5,000MB/s read and 3,000MB/s write. The headline 6,000/5,000MB/s figures apply to the 1TB and 2TB variants.

ℹ️ Heatsink clearance — the included heatsink adds approximately 1mm of height. Suitable for most desktop M.2 slots; verify clearance in compact SFF builds. For PS5 installation, the heatsink fits without modification.

ℹ️ DRAM-less design — the Legend 860 uses HMB rather than on-drive DRAM. HMB is active on Windows 10 and later and on PS5; full benefit requires a compatible NVMe driver on PC.
