Not sure how to best proceed with a spare drive I have. Here's the situation: I'm running Windows 10 Pro on a mid range Dell laptop. I recently replaced my spinning 2.5" SATA drive by cloning to a new SSD. I'd like to put this now spare drive to good use, and have purchased an enclosure kit with USB 3.0 I/O. I plan to use the drive primarily for on-site file backups. I'll be backing up the standard MS files like .docx, .xlsx etc, and non-OS specific files like pictures, videos and so on. To do so, I was planning on just formatting the drive using the standard DOS format command. I assume this would result in a blank slate NTFS hard drive, ready for use with Windows like any other external or flash drive. Please correct me if I'm wrong here.
Things become a bit more complicated (at least in my mind) if I decide to pursue a little home NAS experiment I've been pondering. I like to tinker, and will be buying the latest Raspberry Pi soon. The later generation RPi's can apparently be used successfully as a controller for a simple home NAS. Works for me, I've now got a spare drive and only two PCs in the house.
However, RPi's obviously don't run on Windows, they run on any number of different Linux distributions. The good news is that NTFS will apparently not be a problem. So... what to do with my SATA drive? Keep it as is, preserving files and the OS, but limiting space? Format to NTFS and as a result, lose the Windows partition? And would that even matter? I don't know nearly enough about NAS to understand OS issues when the client PCs are Windows but the drive is controlled by hardware running Linux.
As I've written this, I think I've answered my own question but... I'm not that confident I'm right. Any informed feedback on the subject?
