Thank you.
I'll try connecting the drives with a 3ware 9650SE-16ML card that I could get at a good price. It offers no less than 16 SATA ports, has a lot of RAID modes and allows to view disks as single disks too. D

Concerning DMDE, I wonder if the ext4 recovery permits quick recovery of deleted files using the journal, like extundelete does, or if I will have to scan the whole 16TB virtual RAID image. Any idea ?
Which DMDE, can you directly browse the virtual RAID if the file system is valid or do you have to perform a full data recovery (i.e. full analysis of the virtual RAID) before you can see the folders and files ?
Sure (IF the filesystem is recognized and it is basically "sound") you can browse the filesystem contents "as they are" (i.e. not including deleted folders/files and/or incorrect entries, etc.).

No ideas.
I don't think I ever used it on a "Ext4" filesystem, on NTFS it reads/analyzes the $MFT for delete files/folders/etc. only when you do a "Virtual reconstruction" of the filesystem, on "normal" sized volumes it takes but a bunch of seconds to this search/reconstruction.
Just like I was tempted to answer to the previous question 😯 , why don't you simply try it?
I mean, you can get the Freeware version for free, it has a few limitations, but the behaviour is I believe essentially the same as the "Full" program, and you can abort the "Virtual reconstruction" if you see it takes too long.

Currently, DMDE does not use the journal for ext4.
Regarding ext4 it is more helpful for data recovery from damaged file system than for the recovery of deleted folders/files.
For ext2/3/4 file systems, it's practically impossible to recover the folders structure with the right names, because of the way the deletion is done in the file system.
UFS Explorer Professional can use a virtual RAID image and seems using miscellaneous recovery approaches, including the journal.

I thought that if you deleted a directory you could recover all its contents including the names (not the name of the directory itself though) since the directory index is stored as a file. Does the filesystem driver traverse and delete the entries inside the directories as well?
