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.

    Thanks for the test. Was quite for some time here.

    Overall good SSD, buuuuuttt
    1) Adata don’t have my trust after all this part swapping
    2) Price 120 Shekels msrp sounds right, but in Europe the likes of WD SN850/Samsung 980 Pro 1 TB already down to 145/150Shekel and a couple of times a month at deals down to 130/140.
