I have an aging home-built system from 2011 with an at the time nice i5 2500K processor, 4gb ram, 128gb SSD, etc. It's been a great system and all the speed I really need for what I use it for. I've recently acquired a nice Dell Mobile Workstation M4800 with a newer i7 4900MQ, 256 mSATA SSD, nvidia graphics card, and 32gb of ram. So, I'd like to use this as my main unit, but also would like to have a RAID drive setup, which from what i'm finding is difficult with a laptop. So I guess I'm wondering what the ideal way to set these up would be. Should I keep the laptop as the main unit, and have the old desktop as a data farm? I mainly just want to make sure my 50gb of pictures are backed up and safe. I have a 2TB data drive in the desktop, and was thinking of adding another 2TB and creating a RAID array for redundancy. But, how can I do this with the laptop as the main unit? Should I get an external RAID case and another 2TB drive, or can I use my desktop to perform the same function? How would I connect it to the laptop? Could I make it a NAS? The mb and processor and ram and all of that would just go to waste in the desktop PC, so thought maybe I could use that somehow. Let me know some ideas. Thanks!
