ADATA Falcon 256GB PCIe 3.0 NVMe SSD

Posted on May 17, 2026 by Raymond Chen

The ADATA Falcon 256GB is a budget PCIe 3.0 NVMe SSD using a Realtek controller and Host Memory Buffer instead of dedicated DRAM, rated for 3,100 MB/s reads at an entry-level capacity.

ADATA Falcon 256GB PCIe 3.0 NVMe SSD

The ADATA Falcon 256GB uses the Realtek RTS5762D controller paired with 3D TLC NAND and no dedicated DRAM chip. It relies on the NVMe Host Memory Buffer (HMB) to borrow system RAM for the flash translation layer, keeping costs down while maintaining usable performance on modern platforms.

ADATA rates the 256 GB model for 3,100 MB/s sequential reads and 1,500 MB/s sequential writes, with 180,000 random read and write IOPS. The drive ships in an M.2 2280 form factor. ADATA covers it with a five-year warranty.

The Falcon targets budget builders who want NVMe speeds on a PCIe 3.0 platform without paying for DRAM-equipped drives. The HMB dependency means it performs best on systems with Windows 10 or later and a compatible NVMe controller. The 256 GB capacity is suitable as a boot drive or for lightweight installations. Direct competitors include the Kingston NV2 250GB and the WD Blue SN570 250GB.

🚀 Performance and benchmarks

ADATA rates the Falcon 256GB at 3,100 MB/s sequential reads and 1,500 MB/s sequential writes, with 180,000 random read and write IOPS. The read speed sits below the PCIe 3.0 ceiling of roughly 3,500 MB/s, and the write speed is modest even by PCIe 3.0 budget standards.

  • ADATA SX 8800 Pro 512 GB: 3,500 MB/s read, 2,700 MB/s write
  • ADATA SX 8800 Pro 1 TB: 3,500 MB/s read, 2,700 MB/s write
  • ADATA XPG Spectrix S40G RGB 256 GB: 3,500 MB/s read, 3,000 MB/s write
  • ADATA XPG Spectrix S40G RGB 512 GB: 3,500 MB/s read, 3,000 MB/s write
  • ADATA Falcon 256 GB (this drive): 3,100 MB/s read, 1,500 MB/s write

The Realtek RTS5762D controller is a budget part, and the HMB architecture limits random IO consistency under heavy multi-tasking. For everyday desktop use, boot times, and application launches, the drive performs adequately. The SLC write cache buffers burst writes, but sustained transfers will hit TLC-native speeds quickly at this capacity. Independent reviewers found the Falcon competitive with other budget DRAM-less PCIe 3.0 drives in its price tier.

🖥️ Endurance and warranty

ADATA covers the Falcon with a five-year limited warranty. Endurance ratings for the Falcon vary by capacity; the 256 GB model is rated for a lower TBW than the larger capacities. ADATA's SSD Toolbox software monitors drive health and provides firmware updates. Warranty claims are processed through ADATA's service portal or the original retailer.

Conclusion

The ADATA Falcon 256GB is a basic PCIe 3.0 NVMe SSD for budget builds. Its 3,100 MB/s reads and HMB design keep costs down, but the 1,500 MB/s write speed and 256 GB capacity limit its appeal to boot-drive duty. The Samsung 980 250GB offers higher writes at 3,000 MB/s for a similar price, making it the stronger budget pick at this capacity tier.

+ Pros

  • 3,100 MB/s sequential reads at a low price

⁉️ FAQ

The Falcon 256GB handles basic gaming with its 3,100 MB/s read speed, which is adequate for game loads on a PCIe 3.0 system. The 256 GB capacity limits how many games you can install alongside the OS. For a gaming-focused build, the 512 GB or 1 TB model is a more practical choice.

The Falcon uses the NVMe Host Memory Buffer (HMB) feature instead of dedicated DRAM. HMB borrows a small amount of system RAM to cache the flash translation layer. This requires Windows 10 or later and a compatible NVMe controller. Without HMB, random IO performance degrades.

No, the PS5 requires a PCIe 4.0 NVMe M.2 SSD with recommended reads of 5,500 MB/s or higher. The Falcon is a PCIe 3.0 drive rated at 3,100 MB/s reads and does not meet Sony's requirements.

The Samsung 980 offers higher reads at 3,500 MB/s versus 3,100 MB/s on the Falcon, and higher writes at 3,000 MB/s versus 1,500 MB/s. Both are DRAM-less with HMB. The Samsung uses its own Pablo controller and V-NAND, while the Falcon uses a Realtek controller. The Samsung 980 is the stronger drive in most metrics.

Yes, the Falcon uses a standard M.2 2280 form factor that fits most laptops with an M.2 NVMe slot. The DRAM-less design and low power draw make it suitable for mobile use. HMB support requires a compatible system, which most modern laptops provide.
