Lenovo NAS ix4-300d

I have a Lenovo NAS in for the first time. Its set up as a RAID 5. All drives are the same size so I presume this is working on a standard RAID 5 setup. Drives are imaging at the moment. Two have physical issues but look recoverable. I see it has 'data protection' but looks like it failed to rebuild due to the two failed drives so at least one thing is in our favor.

If anyone has any experience of these units, are they a standard RAID 5 setup when all drives are the same size from new? Or are they a hybrid type of setup?

Nearly all NAS arrays will be a sort of RAID of partitions or LVMs. Usually each disk will have a OS partition which is a RAID 1 across all disks (that way any one disk can boot the NAS), then there will be a data partition which contains LVMs which are in a RAID.

Do yourself a favor and see if R-Explorer/UFSExplorer can just recognize the array once all drives and/or images are connected. Often it will for NASs.

Yep, will do and thanks. But but it was more a question about if the are like SHR or Drobo Beyond RAID as it has this 'data protection' feature.

SHR is still a combination of LVM and md-raid, as is X-RAID, just named in a fancy way. Drobo has its own specific format.
