ADATA LEGEND 900 PRO 2000GB

The ADATA LEGEND 900 PRO 2000GB is a high-performance NVMe 1.4 storage solution designed to saturate the PCIe 4.0 x4 interface. It typically targets 7400 MB/s sequential read and uses an 8-channel controller architecture (likely InnoGrit IG5236 or Silicon Motion SM2264) paired with high-layer 3D TLC NAND. The drive employs a DRAM cache buffer for mapping tables to maintain sustained throughput and low latency. It ships with a low-profile aluminum heat spreader pre-applied, which is adequate for burst workloads but may lead to thermal throttling during sustained heavy writes; the pre-applied spreader can be difficult to remove without risking the NAND packages. ADATA uses multiple component suppliers across batches, and the drive's read throughput exceeds PlayStation 5 recommended specifications, making it a viable expansion option despite lacking a heavy heatsink.
