Adata Falcon NVMe SSD: Fast reader, so-so writer, great value

Though it's a slow writer by NVMe standards, the 1TB Adata Falcon is a great everyday performer in the real world and a bargain to boot.

Though it’s a slow writer by NVMe standards, the 1TB Adata Falcon we tested is a great real-world, everyday performer. It’s also priced below the competition at the moment (currently $157.61 on Amazon). We don’t recommend it for pros or heavy workloads, but it’ll save casual computing types and bargain PC vendors a buck or two.

Specs and pricing

The 2280 form factor (22 mm wide, 80 mm long), x4 PCIe 3.0 Falcon is available in other capacities: 256GB ($46 on Newegg), 512GB ($70 on Newegg), and 2TB ($264.47 on Newegg). They're all just a bit cheaper than the average bargain drive at the time of this writing.

Despite the lowball pricing, Adata outfits the drive with classy-looking gold heat spreader. That hardly makes the Falcon an SSD you’ll want for heavy-duty use, but it’s a nice touch anyway.

Adata’s Falcon is a good budget drive. Its read performance is excellent, and the write performance steady, as long as there’s SLC cache available.

The Falcon employs a Realtek RTS5762DL controller to shuffle data in and out of the 96-layer stacked/layered/3D TLC (Triple-Level Cell/3-bit) NAND. The drives are rated for 150TBW (TeraBytes Written) per 256GB of capacity, and carry a full-five year warranty. That’s a rather low TBW rating, but two years’ more warranty than some.

As the components for nearly all SSDs (and many pre-made products) come from the same few fabs, TBW ratings and warranty are dictated largely by legal and financial concerns. Basically the cheaper the drive, the lesser the guarantee. Note that SSD failure in end-user PCs has proven very rare, so the warranty is not quite the concern it is with hard drives. 


I gave away most of the performance story early in the article—fast reader, slow writer. However, while the Falcon’s writing is a tad slothful according to CrystalDiskMark 6, it’s not particularly slow in the real world. Part of the reason for the slow write rating is that there’s no DRAM cache to pump up that operation with smaller batches of data.

CrystalDiskMark 6 rated the Falcon as a excellent reader and a so-so writer. Longer bars are better.

As you can see below, the Adata Falcon proved a well-rounded drive (for the price) when it comes to our real-world 48GB transfer tests. Not as fast as some, but faster than Crucial’s P2.

Though it was quite on par with the Kingston KC2500 or Samsung 970 EVO Plus, the 1TB Falcon’s real world transfer performance was decent. Shorter bars are better.

While the Falcon didn’t ace the 450GB write test shown below, it wasn’t tragic either. Note that the smaller 256GB and 512GB capacities will turn in worse times due to having less SLC cache available.

The Falcon ran out of cache about 70 percent of the way through this write, but still turned in a decent time. (Shorter bars are better.) The 256GB and 512GB capacities will run out of cache sooner and take more time. 

You can see from the capture below that while the Falcon is good while there’s sufficient cache, it’s very slow (250MBps) when it runs out. This means the smaller 256GB and 512GB drives with smaller SLC caches will slow down sooner and take longer when writing large files.

Note also that as any drive fills, there’s less NAND available to treat as cache, and you’ll see the same drop in performance.

The Falcon allots quite a bit of TLC for use as SLC when it’s available. However, write performance suffers mightily when it runs out. That shouldn’t happen often with the 1TB and 2TB models, but it is a concern with the 256GB/512GB capacities.

A bargain for the average user

If you’re not the type that writes large amounts of data often, the Falcon can save you a buck or two and still deliver top-notch everyday performance. However, my standard beef with bargain drives still applies: They simply don’t save you that much money compared to a more consistent performer such as Kingston’s KC2500.

Ultimately this laptop has achieved everything I would hope for in a laptop for work, while fitting that into a form factor and weight that is remarkable.

This smart laptop was enjoyable to use and great to work on – creating content was super simple.

It really doesn’t get more “gaming laptop” than this.

Jack Jeffries


As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

Taylor Carr


The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
