ADATA will use the same master and flash for XPG Atom 50 series SSDs


ADATA promises that XPG Atom 50 series SSDs will maintain consistency, will use the same master and flash.

At present, many SSD manufacturers in the market may ignore the consistency of accessories and use different main control chips and NAND flash memory chips on the SSD, which will be more obvious on some low-end SSDs.

Generally, SSD manufacturers will only advertise a specific set of performance and endurance figures as goals that can be achieved by any combination of master chips and NAND flash chips. Kingston’s NV1 series SSD is a good example .

This entry-level NVMe SSD with a good price/performance ratio has several combinations.


This disregard for component consistency seems to be an increasingly common trend among SSD manufacturers, which worries many consumers. SSD manufacturers also have their own reasons.

In the past year or so, there has been a serious shortage in the semiconductor supply chain, and it is difficult to ensure a stable supply of components. This mixed use approach is also a solution.


Recently, ADATA promised in an exclusive interview with TechPowerUp that all XPG Atom 50 series SSDs on the market will use the same main control chip and NAND flash memory chip.

In other words, the XPG Atom 50 series SSD will always use the InnoGrit IG5220 master controller and Micron’s 176-layer 3D TLC NAND flash memory chip (B47R).


The XPG Atom 50 series SSD is an entry-level NVMe product released by ADATA in November last year, with M.2 2280 specification, PCIe 4.0 x4 lanes, sequential read and write speeds of 5000/4500MB/s, and random performance of 440K /400K IOPS, available in 512GB and 1TB specifications, and a five-year warranty.

The product is also compatible with the Sony PlayStation 5 game console and is equipped with an ultra-thin heat sink.
