Is there a max r/w speed for SSDs in my T470?

I searched Intel's datasheets for my i7-6600u, where I found that the DDR4 RAM is capped at 2133 MHz, but I couldn't find out of there is a cap for any M.2 SSD speeds. Would I be able to install the latest Samsung SSD for example? Or do I need to be selective?

Re: Is there a max r/w speed for SSDs in my T470?

A PCIe m.2 SSD in the primary slot is only served by two lanes, so max speed is around 1700MB/s.  A SATA m.2 in the WWAN slot will max out at around 500MB/s.


There are always chances for specific incompatibilities, but I'd expect that if the slot's and SSD's form factors and interfaces match - 2280/PCIe in the main slot and 2242/SATA in the WWAN slot - you should be OK.
