It depends on what you mean by failed. http://serverfault.com/questions/732167/recover-data-from-raid-1-array-failed/732170#732170 – Ryan Babchishin Oct 28 '15 at 23:37

Does the new PE720 have the same RAID controller, or at least one that's known to be compatible with whatever got written to the disks by the old controller? – roaima Oct 28 '15 at 23:38

If both disks of the RAID have failed, it's entirely possible that you can't restore the data. In that case, you should stop experimenting with the disks yourself and send them in to a proper data recovery firm (and prepare to pay a lot for this). Fiddling around yourself would just decrease the chance the of successful recovery.
Of course, if the data was important, you surely have a backup you can simply restore to new disks ...
