ADATA Falcon 2TB Review — Mid-Range PCIe 3.0 NVMe SSD

Posted on May 17, 2026 by Raymond Chen

The ADATA Falcon 2TB is the largest capacity in ADATA's mid-range Falcon lineup, offering bulk NVMe storage with strong read speeds at a competitive price.

ADATA Falcon 2TB Review — Mid-Range PCIe 3.0 NVMe SSD

The ADATA Falcon 2TB shares the same hardware as the rest of the Falcon family — the Realtek RTS5762D controller paired with 3D TLC NAND, no dedicated DRAM cache, and a combination of SLC caching with the NVMe Host Memory Buffer protocol. The drive ships in a standard M.2 2280 form factor. At 2 TB, it is likely a double-sided PCB design, which means it may not fit in laptops with tight M.2 slot clearances. Desktop installations are unaffected.

ADATA rates the 2 TB model at 3,100 MB/s sequential reads and 1,500 MB/s sequential writes, with up to 180,000 IOPS for random 4K reads and writes. The read speed is close to the PCIe 3.0 x4 ceiling of approximately 3,500 MB/s. What is unusual about the Falcon series is that the 2 TB variant does not receive a write speed bump over smaller capacities — it maintains the same 3,100/1,500 MB/s ratings as the 256 GB and 512 GB models. Most NVMe drives benefit from faster writes at higher capacities due to having more NAND channels to write across. The Falcon series does not follow this pattern. The Falcon also ships in 256 GB, 512 GB, and 1 TB capacities.

The 2 TB capacity is where the Falcon makes the most practical sense. At this size, it can hold the operating system, a large application library, and 20 or more modern games — genuinely useful as a single-drive solution for budget-to-mid-range builds. The drive sits between ADATA's entry-level Swordfish and the performance-oriented XPG series. Direct competitors in the 2 TB tier include the Kingston A2000 2TB and the WD Blue SN550 2TB.

Under sustained write workloads, the Falcon shows the limitations of its DRAM-less HMB design. StorageReview's testing found the drive's sustained throughput resembling budget QLC designs despite using TLC NAND, with latency routinely exceeding one millisecond across synthetic workloads. For a 2 TB drive used primarily as a game library or bulk storage, this behaviour is rarely encountered. But anyone planning sustained large-file transfers should look at faster alternatives.

🚀 Performance and benchmarks

The ADATA Falcon 2TB is rated for 3,100 MB/s sequential reads and 1,500 MB/s sequential writes, with up to 180,000 random read and write IOPS. The 3,100 MB/s read speed approaches the PCIe 3.0 x4 ceiling of roughly 3,500 MB/s, making the Falcon competitive on paper with mainstream drives. For users upgrading from SATA, the Falcon delivers nearly a sixfold improvement in sequential reads — boot times, application launches, and game load times will feel significantly faster.

ADATA Falcon 2 TB (this drive): 3,100 MB/s read, 1,500 MB/s write

The write speed of 1,500 MB/s is more modest, and the fact that the 2 TB variant does not receive a write speed bump over smaller capacities is unusual. Most NVMe drives benefit from faster writes at larger capacities. Mainstream PCIe 3.0 drives like the Samsung 970 EVO Plus and WD Black SN750 reach 2,500–3,000 MB/s writes on their 2 TB variants, putting the Falcon at a meaningful disadvantage for sustained write workloads. The DRAM-less HMB design also introduces a dependency on proper system-level support.

Under sustained write loads, the Falcon's limitations become clear. StorageReview's testing found that the drive's sustained throughput more closely resembled budget QLC designs than typical TLC hardware, despite the Falcon using 3D TLC NAND. Latency routinely exceeded one millisecond across synthetic workloads, placing the Falcon near the bottom of comparison charts. The 4K random write performance peaked at approximately 12,408 IOPS, and 64K sequential writes reached only about 220 MB/s. For a 2 TB drive used primarily as a game library or media archive, sustained write limitations are rarely encountered — games are read far more often than written. But anyone using the Falcon 2TB as a scratch disk for video editing or for regular large-file transfers will experience sharp slowdowns once the SLC cache fills.

🖥️ Endurance and warranty

ADATA covers the Falcon 2TB with a five-year limited warranty, capped at 1,200 TBW (terabytes written). At a typical consumer write workload of 20 GB per day, 1,200 TBW translates to approximately 164 years of use — far beyond the warranty window. Even at a heavy 50 GB per day, the drive would last roughly 66 years. The 1,200 TBW rating is the highest in the Falcon lineup and is competitive with mainstream 2 TB NVMe drives — the Samsung 970 EVO Plus 2TB is rated at 1,200 TBW as well, making the Falcon's endurance on par with faster competitors. The MTBF rating is 1.8 million hours. ADATA provides the SSD Toolbox utility for monitoring drive health, checking remaining endurance, running diagnostics, and applying firmware updates. The five-year warranty covers manufacturing defects and does not extend to drives that exceed their TBW rating within the warranty period.

Conclusion

The ADATA Falcon 2TB is the most compelling variant in the Falcon lineup simply because of its capacity. Two terabytes of NVMe storage with 3,100 MB/s reads is genuinely useful for game libraries, media archives, or as a single-drive solution for budget-to-mid-range builds. The 1,500 MB/s write speed is modest, and under sustained write loads, the DRAM-less HMB design shows its limits with QLC-like throughput. For buyers who prioritize read speed and capacity — gamers, office workers, or anyone upgrading from SATA — the Falcon 2TB delivers well. For sustained write workloads, the Samsung 970 EVO Plus 2TB or WD Black SN750 2TB are better choices. The Falcon makes sense when priced below these faster alternatives.

⁉️ FAQ

The ADATA Falcon 2TB is a solid budget gaming drive from a capacity standpoint. Two terabytes provides enough space for the operating system and 20 or more modern games, and the 3,100 MB/s reads deliver fast game load times — significantly faster than any SATA SSD. However, the drive's sustained write performance is modest at 1,500 MB/s, so installing multiple large games simultaneously will take longer than on a mainstream NVMe like the Samsung 970 EVO Plus. For game loading specifically, the Falcon's read speed is its strength, and at 2 TB, capacity is rarely a constraint.

No, the ADATA Falcon 2TB is not compatible with the PlayStation 5. Sony requires a PCIe 4.0 NVMe M.2 SSD with sequential reads of at least 5,500 MB/s for PS5 storage expansion. The Falcon is a PCIe 3.0 drive rated at 3,100 MB/s reads, well below Sony's minimum. It also ships without a heatsink, which the PS5 mandates for M.2 expansion drives. The Falcon works well as a PS4 hard drive replacement, offering much faster load times than the stock mechanical drive, but it cannot expand PS5 storage.

No, the ADATA Falcon 2TB does not have a dedicated DRAM cache. It uses a combination of SLC caching and the NVMe Host Memory Buffer (HMB) protocol. HMB allocates a small portion of system RAM — typically a few megabytes — to manage the flash translation layer, while the SLC cache provides a fast write buffer for burst workloads. This DRAM-less design keeps costs down but limits sustained write performance. Under heavy loads, the Falcon's throughput drops to levels more typical of QLC drives, which is the trade-off for the DRAM-less architecture.

ADATA rates the Falcon 2TB at 1,200 TBW (terabytes written), covered by a five-year limited warranty. At a typical consumer write workload of 20 GB per day, 1,200 TBW would last approximately 164 years. Even at a heavy 50 GB per day, the drive would last roughly 66 years. The 1,200 TBW rating is the highest in the Falcon lineup and is competitive with mainstream 2 TB NVMe drives — the Samsung 970 EVO Plus 2TB is rated at 1,200 TBW as well. Most users will never approach the TBW limit within the five-year warranty period.

The ADATA Falcon 2TB does not ship with a heatsink, and it does not strictly require one. As a mid-range PCIe 3.0 drive with 3,100/1,500 MB/s speeds, the Falcon generates moderate thermal output — more than budget drives like the Swordfish but significantly less than high-performance PCIe 4.0 drives. However, the 2 TB variant is likely a double-sided PCB design, which can run slightly warmer than single-sided drives. Most modern desktop motherboards include built-in M.2 heatsinks, and if yours does, using one is recommended. If installing in a laptop, check that the M.2 slot has enough vertical clearance for a double-sided drive.

The ADATA Falcon 2TB and WD Blue SN550 2TB compete in similar mid-range territory. Both are DRAM-less PCIe 3.0 drives using HMB. The Falcon is rated at 3,100/1,500 MB/s, while the SN550 2TB is rated at roughly 2,400/1,950 MB/s — the Falcon has a read speed advantage, while the SN550 writes faster. Both drives share similar sustained write limitations under extreme loads, a common trait of DRAM-less architectures. In practice, the Falcon's faster reads benefit game loading and file reads, while the SN550's faster writes benefit large file copies. Choose based on which is cheaper.

The ADATA Falcon 2TB uses the M.2 2280 form factor, which is the standard size for laptop M.2 slots. However, the 2 TB variant is likely a double-sided PCB design, meaning NAND chips are mounted on both sides of the board. Some thin laptops — particularly ultrabooks and compact gaming laptops — have tight M.2 slot clearances that may not accommodate a double-sided drive. Before purchasing, check your laptop's service manual or specifications for M.2 slot clearance. Desktop installations are unaffected by this concern.

Yes, the ADATA Falcon 2TB is well-suited as a secondary storage drive. Its 2 TB capacity makes it ideal for game libraries, media archives, or bulk file storage. The 3,100 MB/s reads are fast enough that loading games and files from the Falcon will feel snappy. The drive's sustained write limitations matter less in a secondary role, where large sequential writes are less common. Pair it with a faster primary drive for the operating system, and the Falcon 2TB serves as an excellent budget expansion drive.
