Recover content of NAS drive from network Recycle bin

Specs: Win 10 , I7
I stupidly moved a huge root folder to my Qnap TS415 NAS to the network Recycle bin , unfortunately I could not recover the data from within the NAS OS . This is a new NAS and the supposed back up drives were in the mail - so too late to back up now

So I am doing a bit of research in data recovery , as I know from my college classes that data is actually quite difficult to delete. I am not implying it is easy to recover either , however I digress. Now there seems to be , correct me if I am wrong ? A two step process of data recovery for Raid the first part rebuilding the raid which involves a bit of tinkering such as specifying the order of the drive. start sectors and parity orders

Also what are the best tools for this ? The QNAP runs a bespoke flavor of Linux called QTS , the four 2TB drives were in a Raid 5 config, the File system is EXT afaik. . I have scoured the internet already , I can see a plethora of tools and programs out there . Also I am happy to build a linux or windows desktop and connect up all the drives in order to do this , however I require a bit of guidance - if anyone can point me in a preferable direction to the best process I would appreciate it

Now I know the order of the drives as I have written the order on the physical enclosures , however I am contemplating the data recovery procedure and having to look at things like start sectors and parity orders but I wouldn't know where to find these, again any information on this would be great
. However as the raids technically didn't failed ( just half the data missing - probably deleted) , would I really need to rebuild it? Or is the rebuilding just part and parcel of the process ?

According to the comments in the guide given in link above (http://qnapsupport.net/teknik-destek/raid-0-5-6-ve-10dan-veri-kutarma/photorec-ile-veri-kurtarma/?lang=en)

The recovery process using photorec takes 20 days to recover 20 GB , that means it will roughly take 4000 Days or around 10 years to recover the 600GB of Data that had been deleted

Is data recovery really this long ?
