Our first pick is Disk Drill for supported arrays that assemble automatically. R-Studio earns its place when you need to work out the array's layout yourself.
Disk Drill is our best overall choice for a first recovery attempt on a supported software RAID, thanks to its automatic assembly approach. R-Studio is the better choice for manual reconstruction, unusual layouts, or failed automatic detection. This is a workflow-based recommendation, not a measured recovery-rate win.
Best for: NAS owners attempting a first recovery from a supported, automatically recognized array.
Best for: Experienced users reconstructing an array with missing metadata or an unusual layout.
Read these as two different recovery workflows, not a promise that either app will restore your array. Prices refer to the listed editions, while release dates below refer specifically to Windows builds.

The crucial difference is what happens after automatic recognition fails. These capabilities follow the vendors' RAID documentation, imaging descriptions, plus platform listings.
Decide what you need to solve first: finding missing files, or reconstructing the array that held them.
For our intended reader, fewer configuration decisions are useful. For a technician, those same missing controls can be a dealbreaker.
These are paraphrased user reports, not verified recovery tests. Several concern ordinary disks rather than RAID.
The poster reported recovering camera photos, praising the clear recovery steps. They explicitly said they had not tested RAID or network storage.
After accidentally reformatting a large disk, this user found Disk Drill's results poorly organized, with confusing filenames. They preferred the results from R-Studio.
This user reported recovering their reformatted disk's files with the original folder structure through R-Studio. It is a single reported outcome, not a controlled comparison.
A user working on a failed LaCie RAID 0 reported seeing only some files in R-Studio, with no recognized partition matching the array's full size. Their attempt remained unresolved in that account.
Disk Drill earns our 8.8/10 top pick for a first attempt on a supported array. Its automatic assembly workflow is the reason to start there, not a claim that it can solve every RAID failure. R-Studio scores 8.6/10 for this audience, but is the stronger option when custom reconstruction becomes necessary. If automatic detection produces no usable volume, change your approach rather than assuming another identical scan will help.
Before paying, inspect several large files from different folders, not just one small thumbnail.
