XPG Atom 50 1TB PCIe Gen4 x4 M.2 SSD Review

XPG Atom 50 1TB Introduction

The XPG Atom 50 is a PCIe Gen4 x4 M.2 2280 solid state NVMe 1.4 drive featuring LDPC and AES 256-bit encryption for data protection, SLC caching and Host Memory Buffer technology, and provides up to 5,000 MB/s read speed and 4k random IOPS up to 650K/600K read and write. The Atom 50 is also compatible with the PlayStation 5 gaming console as a expansion drive.

The Atom series SSDs are marketed as having only high quality ICs that have undergone rigorous testing, and for further assurance it comes with a 5-year warranty; furthermore, the drive is expected to write no less than 650TB of data before failing. Currently the XPG Atom 50 isn't yet available, but will likely retail for around $180 USD.

XPG Atom 50 1TB Closer Look

The packaging for our review model confirms this drive offers 1TB of capacity. The box contents are simple, with a plastic form holding both the drive and the thin metal heat spreader with adhesive tape.

The XPG Atom 50 has two ADATA ICs for storage, with room potentially for two more chips on this PCB model. The rear of the drive has a large sticker with cutouts on one side to make removal virtually impossible.

Applying the heat spreader is very easy, although there are no direct guides on how to do it. Basically find the notched side that will go on the screw hole side. Then do your best to center the heat spreader over the drive and gently press down. It doesn't have to be perfectly centered as long as the heat spreader doesn't extend much beyond the drive's body. Thankfully on the XPG Atom 50 all of the ICs face away from the motherboard, so it should be possible to actively cool them for good results.

The XPG Atom 50 is indeed fast! Both read and write speeds exceeded the advertised speeds, although this rate will decrease some if the drive is used as the primary (and as its capacity is gradually used up). Regardless this drive will be blazing fast for gaming and media work!

The XPG Atom 50 is an extremely fast M.2 NVME drive rated for 5,000 MB/s read and 4,500 MB/s write speeds, but in testing I saw an average of 5,039 MB/s and 4,834 MB/s, respectively! The combination of a solid 650TB TBW (Terabytes Written) and 2,000,000 MTBF (mean time between failures) ratings, along with a 5-year warranty are compelling features that provide additional reassurance. The XPG Atom 50 uses the common 2280 M.2 form factor, and both onboard storage ICs will be facing away from the motherboard for superior cooling potential.

3D NAND has certainly come a long way, as evident with these insanely fast speeds being achieved by only two storage ICs! XPG states that the Atom 50 is also tested and compatible with the Sony PS5 gaming console as a secondary storage slot for additional high-speed storage. As mentioned earlier, retail pricing will likely be around $180 USD.
