KINGMAX Semiconductor Inc., a global leading provider of memory products, is proud to announce today the launch of its M.2 2280 PCIe 4.0x4 (Gen 4 x4) SSD PX3480 solid-state drive.

Users can fully experience the higher speeds of PCIe SSDs when turning on devices, loading games, and transferring or saving data.
 
The 3 year warranty is not too bad in my opinion. I just wish M.2 memory capacity would increase over 2TB. 
 

 

I use a 512GB SSD for windows, 8TB disk handles my Steam library and a 4TB disks handles Origin et al, iTunes also has a 4TB disk
 
My chassis has room for 5 hard disks and 6 DVD drives so I have lots of flexibility.
