I have a potato laptop and I intend to use blender from ubuntu in order to get somewhat better performance for rendering and modelling and other stuff.
I also need windows because I use davinci resolve (free version) for video editing and free version have problem with encoding H264,also I am starting to hate windows. My stupid task manager keeps showing high disk usage.
So I thought about installing ubuntu on an external hdd and use it for blender because I know its awesome, I saw some benchmark results and there was 30% boost , but I am concerned about performance because if I won't get similar kind of performance boost than sadly I would have to work as a slave under windows and I would never be able to become truly free.
So my question is
Will I get same kind of performance with installing ubuntu on external hdd as i will get with internal Hdd ?? Also what if I use ssd
I need it specifically for blender and i would be happy with that
Or should i dual boot? hmmmmmmmmmmmm........
I have 8 Gigs of ram, i5 7th gen 2.5ghz, nvidia 940mx 2gb and intel graphics 4gb
Thanks in advance for answering (arigato)

SATA 3.0 has 6.0Gb/s transfer speeds. The Wikipedia page also shows comparisons to other buses (ie: SATA vs USB). Thunderbolt 2/3 and USB 3.1/3.2 appear faster, but I believe USB is half duplex, while SATA is full. Additionally, it seems the packets, or how USB communicates, is less efficient for disks than those of a SATA connection.
The SSD is capable of using multiple PCI lanes to connect, and I think the PCI bus is closer to the CPU or has higher priority, though I'm having a hard time finding any evidence to support this.
Reasons why to use SATA over USB are discussed in more detail in this post.
Alongside these reasons, you could use your external hdd to store non-system files, such as media or other data you'd want to carry over to your next machine. Keep all of the system data on the internal HDD and when you switch computers, all of your personal data and files can be easily taken with you.
