Hi Dell;

Using Dell Latitude E5570 equipped with 500 GB HDD.

Now I need to add M2 SSD for more storage and speed.

Dell Latitude E5570 has both HDD and M2 Slot, But when 2.5 inch HDD is inside then there is no space for M2 slot.

I need both HDD and M2 to work at same time.

In documentation it is stated that 

"Drives:
Allows you to configure the SATA drives on board. All drives are enabled by default. The options are:•
SATA-0
SATA-1
SATA-2
M.2 PCIe SSD-0" 

State how to use both slots together and what is (Sata0,1,2 and M2) Is it is 4 Slots?

Regards,

Maalik
