Thanks very much for the good info. I think rather than trying to installing another internal drive I'll take the easy way out and use an external usb3 ssd drive. Should be fast enough for my purpose, a lot easier to install and reasonably priced.
I’m new to Dell PCs having just replaced my old pc with this 3891. I see in the specs there are two sata ports. Came from the factory with one Sata and one SSD. I haven’t opened the cover yet but is there a slot for a second sata drive? TIA
