Load Temps

At full load, temperatures reached a high 69 degree Celsius, which is very good. I’ve known other PCIE 4.0 devices or other Gen4x4 SSDs have reached higher, at 69 degrees is a record low. 



Verdict and Conclusion

After seeing and hearing about the performance increase of Gen4x4 SSDs at Computex last year, I’ve always wanted to give them a try on our test rig, and to see for ourselves what the performance would be like. Well, all I can say is … the ADATA XPG GAMMIX S50 did not disappoint us, not one bit. The read speed reached a phenomenal high of 5,000 MB/sec, which incidentally is what Patriot advertised on the box. Write speeds was also very good, with a score 4,268-4,281 MB/sec. 

The excellent performance of the ADATA XPG GAMMIX S50 is all thanks to Phison’s latest E16 SSD controller, which is currently one of only a few, that fully supports PCIE Gen4x4 standard. You can find out more at Phison’s webiste.

The ADATA XPG GAMMIX S50 comes in sizes of  1TB or 2TB, but sadly no RGB. But hey, who needs RGB when you have phenomenal read/write speeds, backed with a 5 year warranty!

The included gun-metal grey heatspeader looks nice and sleek, and does an adequate job of cooling the SSD … with temperatures reaching a high of only 69 degrees Celsius. I was expecting higher to be honest, but I’m ain’t complaining.

You can buy the ADATA XPG GAMMIX S50 SSD 1TB for around USD $209.99 at Amazon – At this price, it’s a little more than what you would normally pay for a 1TB SSD on the older Gen3x4 standard. But remember, with the latest PCIE Gen4x4 standard, the performance is on another level. You will, however need a X570 motherboard paired with a 3rd Gen Ryzen (Matisse Core) processor.

Final Thoughts

If you don’t care for RGB, but love the read/write speed of Gen4x4 SSDs … then get yourself the ADATA XPG GAMMIX S50 SSD 1TB. It’s one of the fastest M.2 SSDs we’ve tested to date, all thanks to the super fast Phison E16 SSD controller. Of course, you’ll need a X570 motherboard paired with a 3rd Gen Ryzen (Matisse Core) processor to take full advantage of the PCIE 4.0 standard.
