ADATA SLEG-860-1000GCS 1TB PCIe 4.0 x4 M.2 2280 internal SSD

SKU CH-WA85-1C05A MPN SLEG-860-1000GCS

A 1 TB PCIe 4.0 x4 M.2 2280 NVMe 1.4 drive with DRAM cache, 7,400 MB/s read and 6,800 MB/s write, plus an included heatsink

  • Total capacity1 TB
  • Sequential read speedUp to 7,400 MB/s
  • Sequential write speedUp to 6,800 MB/s
  • Interface typePCI-Express 4.0 x4
  • Form factorM.2 2280
  • Random read (4K)730K

Capacity 1TB

  • Sequential reads reach 7400 MB/s for faster boot and load times
  • Sequential writes hit 6800 MB/s to accelerate large file transfers
  • DRAM cache and 3D NAND sustain performance under heavy workloads
  • 780 TBW and 2,000,000-hour MTBF indicate long service life
  • Bundled heatsink helps maintain speeds during extended use

Capacity and interface

The ADATA Legend 860 1TB drive uses a PCIe 4.0 x4 interface in the M.2 2280 form factor. It is built for desktop PCs and the PlayStation 5 console. The NVMe 1.4 protocol and DRAM cache support responsive system operation.

Sustained workload behaviour

Sequential throughput reaches up to 7400 MBps read and 6800 MBps write. Random performance is rated at 730K read and 610K write IOPS. The 780 TBW endurance rating and 2000000 hour MTBF indicate durability for heavy daily write cycles.

Build and installation practicality

A heatsink is included in the package but ships uninstalled, letting the builder choose whether to fit it. The drive operates from 0°C to 70°C and survives storage from -40°C to 85°C. Shock resistance is rated at 1500G for physical resilience.

Questions about this item

How warm does the LEGEND 860 1TB get under sustained PCIe 4.0 x4 loads with the included heatsink fitted?

The drive is rated for 0°C to 70°C operating temperature. The bundled heatsink is designed to keep the controller and 3D NAND within that range during continuous 7400 MBps reads or 6800 MBps writes, and the 2000000-hour MTBF reflects this thermal envelope.

Does my motherboard need a PCIe 4.0 x4 M.2 slot and NVMe 1.4 support to run this ADATA 1TB drive at full speed?

Yes. The SSD uses a PCIe 4.0 x4 interface and NVMe 1.4 protocol; a compatible M.2 2280 key-M slot is required to reach the quoted 7400 MBps read and 6800 MBps write figures.

Will the LEGEND 860 1TB work in a desktop that currently boots from a PCIe 3.0 NVMe drive?

The SSD is backward compatible with PCIe 3.0 x4 slots, so it will function alongside an older PCIe 3.0 boot drive, though sequential speeds will be limited to the 3.0 bus ceiling rather than the native 7400/6800 MBps.
