XPG Atom 50 Gen 4 NVMe SSD Review – A DRAM-less SSD Competes with the Best


We are fairly certain this report should send the anti-DRAMless SSD crowd running for the hills.  It has been just over 9 months since we introduced the world to the newest Samsung 980 DRAM-less SSD and it has held its position as the DRAM-less King of the Hill for some time.  It would not have been a fair proposition to do a side-by-side comparison of the two, not only because the 980 is Gen 3 where the Atom 50 is Gen 4, but also, the ADATA XPG Atom 50 does something we had never seen prior.  Rather than carving out a new performance level for Gen 4 DRAM-less SSDs, the Atom 50 jumps right into Gen 4 territory and surpasses other Gen 4 DRAM-based SSDs.

Don’t believe us?  Take a look at the PCMark 10 result comparison for both Full and Quick Tests and see who sits behind the Atom 50; the XPG Gammix S70 which is a 7GB/s SSD and also that combination of ADATA and Innogrit.  I never would have believed this.  Both were tested on the exact same machine in the exact same conditions.

One could very easilyoverlook the ADATA XPG Atom 50 Gen 4 SSD as it is a value-priced DRAM-less SSD, but one might be wrong to overlook the  true performance this SSD puts out.  Not only does the Atom 50 return very solid speeds of 5GB/s and over 820K IOPS, but also, its low 4K performance of 95MB/s read and 310MB/s write is something nobody would have ever expected from a DRAM-less SSD.  Throw in the low power draw of 2.5W, as well as the added extras such as LDPC and AES 256-bit encryption and the word ‘DRAM-less’ pretty much gets lost in the mix. Editor’s Choice.

Oh… and Yes.  This is fully PS5 compatible.
