How can we recover data from Hard Drives were on RAID 10 without controller?

RAID-6 arrays also have a tendency to big large arrays with large drives, exacerbating the problem.
This is a complex logic. It's something like...
Large arrays tend to use spinners. Spinners tend to use RAID 6 or 10. Large arrays tend to be costly for RAID 10. etc.
But a huge selling point for RAID 10 is that recovery time is flat. Keep adding drives, the recovery time doesn't change. RAID 6, every additional drive can add a bit of time.

And I think people are over-consolidating in their excitement to consolidate everything. Basically ending up with all the eggs in one basket.
We see this a lot. There is certainly a desire for "one pool of storage" and it's so easy now that 10TB drives are so cheap. Heck, I bought one for my kids' video games. 10TB Helium 6Gb/s SATA drive with 256MB cache on my children's video game machine!

Have you checked the SMART values to make sure the drives are degraded and bad? If the drives are good a simple chkdsk may resolve your issues

I recently arranged two 8TB hard drives to clone the drives. Already done with cloning from Disk 2 and Disk 4.
Now reconstructing RAID 0 and trying to recover the data. I tried a couple of software which were saying free and after reconstructing RAID, to recover data it started saying Evaluation.
Is there any open source or completely free software for this requirement?

None that I know of.

NO. If your data is important, pay for the software. otherwise, why bother.

Okay, got it, name some paid software, for RAID data recovery, known to be working or from your experience.

@openit www.runtime.org
GetDataBack for NTFS with RAID Reconstructor.
We've had excellent success with their product. -

@CCWTech does this every day.

Unless you are starting a data recovery firm, it's likely going to be way cheaper to have a service do this rather than to invest in recovery firm tools for one time use.

You don't need a RAID card, in fact don't use one. There is a chance it will overwrite your data. Clone the drives, ONLY work on clones, never on patient drives.

If the drives are healthy, something like ddrescue does a good job. Cloning the entire drive (even empty sectors) is best.
If the drives are NOT healthy, you need professional data recovery equipment. (Ace Labs PC-3000 or at minimum a Deepspar DDI4). If you have a drive with a physical problem and you try to image it w/o professional data recovery gear, you have a good chance of never seeing the data again.
