Chinese electronics & data transferring

writing this on 12th, but will be talking about yesterday
I spend most of my day at work & after that pretty much went to sleep
Yesterday I received a package from china
My chinese electronics arrived
I ordered 4 IDE to Sata boards
Link to boards
Havent tried them yet, but well see when I have time to test them
The idea is to use 2 40X cd drives & 3"5 floppy drive in the frontpanel of my pc
I also ordered 2 different CH341 so I could flash libre boot to my laptops
Link to CH341s
Im lowkey scared to test them out
I will first try on a laptop that isint my daily driver
If that goes well, fuck it up I quess

Other thing I did yesterday was organising my data
Past weeks I have collected 3.9TB of data
150.300 files
from those 329 are movies & 7069 episodes of different series
(*These have been obtained legally ;)*)
But these were already in the correct directories on the NAS
What was not was a 191 directories that had courses, research papers, books, pdf manual & more
Yesterday I trasferred (or atleast started to move) around 12 TB of information
Moved them few times:
From external_drive_1 to NAS
From external_drive_1 to external_drive_2
From NAS to external_drive 3 (Which I carry around with me)
Why I carry them with me has 2 reasons:
1. Backup in different place if something happens to my house for example fire
2. If my friend needs something material/course/movie etc, I can just share it to him
