ADATA Legend 900 NVMe SSD PCIe Gen4 M.2 2280 - 512GB/1TB/2TB
The ADATA Legend 900 NVMe SSD PCIe Gen4 M.2 2280 is a high-speed PCIe Gen4 drive aimed at creators stepping into PCIe 4.0 for the first time. It delivers sequential read speeds up to 7,000 MB/s on PC and can be installed directly in a PS5 as expansion storage, addressing both desktop and console storage needs. Compatible with current Intel and AMD platforms and backward compatible with PCIe 3.0 systems, it offers a straightforward upgrade path for a wide range of setups.
Why this product
PCIe Gen4 x4 with NVMe 1.4 compliance
It uses a PCIe Gen4 x4 interface compliant with the NVMe 1.4 standard, delivering sequential read speeds up to 7,000 MB/s on PC — described as four times faster than standard PCIe Gen3 SSDs.
PS5 expansion drive compatible
It can be installed in a PS5 as an expansion storage device. When the PS5 console is operating, sequential read speed is measured at 6,200 MB/s.
SLC caching and HMB technology
It uses an SLC cache algorithm alongside Host Memory Buffer (HMB) technology to support caching efficiency during read and write operations.
LDPC error correction built in
Advanced hardware LDPC (Low Density Parity Check Code) ECC technology helps ensure data accuracy and file integrity during transmission.
Five-year limited warranty
Every unit comes with a 5-year limited warranty backed by ADATA, alongside backward compatibility with PCIe 3.0 platforms.
Free SSD Toolbox software included
ADATA's SSD Toolbox is included at no extra cost, giving users access to drive management utilities.

- Compatible with current Intel platforms supporting PCIe Gen4 x4 M.2 2280 slots.
- Compatible with current AMD platforms supporting PCIe Gen4 x4 M.2 2280 slots.
- Backward compatible with PCIe 3.0 platforms, though Gen4 speeds will not be achieved.
- Can be installed in a PlayStation 5 (PS5) as expansion storage; sequential read operates at 6,200 MB/s in that context.
- Form factor is M.2 2280 — verify your motherboard or laptop has an M.2 slot of this length before purchasing.
- Not compatible with SATA-only M.2 slots; this is a PCIe NVMe drive and requires an NVMe-capable M.2 slot.
Best for
- Creators entering PCIe 4.0 who want high sequential throughput (up to 7,000 MB/s read) without moving to a higher-tier product.
- PS5 owners needing to expand console storage with a drive that meets the interface requirements and delivers 6,200 MB/s read in-console.
- Users on PCIe 3.0 systems planning to upgrade, since it is fully backward compatible and can be moved to a Gen4 platform later.
- Buyers wanting long-term assurance, given the 5-year limited warranty and 1,500,000-hour MTBF rating.
- High-capacity storage needs for those requiring up to 2TB in the M.2 2280 form factor.
Trade-offs
- SATA-only systems: this drive requires an NVMe-capable PCIe M.2 slot and will not function in SATA-only M.2 slots.
- Buyers needing maximum sequential write speed at 1TB: the 1TB variant writes at up to 4,700 MB/s, lower than the 512GB and 2TB variants which reach 5,400 MB/s.
- Workloads requiring a higher published TBW endurance figure: a TBW figure is only provided in the source data for the 2TB variant (2,000 TB); figures for the 512GB and 1TB variants are not available in the verified record.
- Systems without an M.2 2280 slot: the drive is fixed at the M.2 2280 form factor and cannot be used in desktop or laptop bays requiring a different length.
