PCIe Gen3 vs. Gen4 SSD in Precision 3541

Another question about my Precision 3541:  

The documentation lists the following SSD storage type in the storage section of the Setup & Specifications Guide:  

M.2 2280 solid-state drive PCIe NVMe

PCIe Gen3x4 NVMe, up to 32 Gbps

Up to 2 TB

Does this exclude a Gen4 M.2 2280 NVMe SSD?  Crucial lists their T500 Gen4 SSD as compatible. Wondering if that can be trusted. 

Thanks.

Just like a USB 3 drive can be used on a USB 2 port, Gen 4 NVMe drive is backward compatible with your device and will operate at Gen 3 speed.  So, yes, Crucial drive will work.

Yes, the Precision 3541 does support 4TB of PCIe Gen 4 NVMe SSD.  It will operate at Gen 3 speed.

Check compatible storage from Crucial https://www.crucial.com/compatible-upgrade-for/dell/precision-3541

@Chino de Oro​ Hmm. Your reply brought up a question I've had before: The specs for the 3541 state that (unless you have the 6 cell battery), you can have a PCI NVMe and a SATA HDD drive. It specifically says "up to 2 TB" for a M.2 2280 SSD and "up to 2 TB" for 5400 RPM SATA HDD drive, OR "up to 1 TB" for a 7200 RPM SATA HDD drive.

So I assume there is a wattage concern maybe? (Why does the 5400 RPM drive allow more capacity?)

@erastus1897 , power and wattages are not the limitation factors for storage capacity.  The maximum capacity in Dell specifications referred to the drives capacities Dell tested and validated to work with the systems at the time.  They were available as options for purchase configurations.

When storage uses standard technology users should be able to upgrade with any maximum capacity available in the markets.
