Confusion about SSDs

My old Alienware x51 r1 recently went to PC heaven, rest her soul, after a good long run. As it was breaking down, I thought it might be the hard drive so I tried to replace it with a 250gb Samsung evo 850 SSD. There were issues with more components than just the hdd though, and the pc died.

So now I have ordered a new Alienware aurora r6, but chose the stock option of a 1TB hdd drive, assuming I could just use the ssd I bought for the old pc. But now, after hearing about how much faster m.2 PCIe ssds are, I'd rather have one of those. I have a 4tb external hard drive, so memory space really isn't an issue.

After doing some research, I really want an m.2 ssd. So my question is, would there be any point in having that combination of hard drives all in my pc. Also, I'm confused over exactly what SATA is referring to. I thought SATA was primarily used with SSDs like the Samsung I bought, but I keep seeing something about m.2 ssd satas as well. Can anyone help shed some light on this for me?

Depends on you and your data storage consumption. If you need more storage space than what the M.2 ssd offers with the benefits of a ssd, then yes. Plus the 2.5inch drives bays are a lot more accessible than a m.2 slot.
Also with M.2, the device can get pretty hot which may throttle its performance depending on the M.2 placement on the...
M.2 is just the connector and format factor. What interface a M.2 drive uses will be either sata or pcie which will determine what bandwidth it can have.
A M.2 sata ssd is limited to sata speeds.
A M.2 pcie ssd can be capable of up to 32 Gbps depending how many pcie lanes it uses.

So if I have an m.2 installed, is there any reason to install the 2.5" ssd besides addition storage?

Also with M.2, the device can get pretty hot which may throttle its performance depending on the M.2 placement on the motherboard and airflow especially if you have a gpu on top of it.
