Before you go say that RAID 1 mirrors one drive and cannot mirror twice, that is not what I mean. Actually it can, though then it is often called RAID 1E. I have a WD Black 2 TB HDD and 2 WD Blue 1 TB HDD. The WD Black is to be the main drive, and I need data redundancy. Is it possible to use the two blues coupled together as RAID drives and the ...

Yes, you can. It's a hybrid configuration similar to RAID 0+1. You can search on the Internet how to set your specific hardware.

I had the same issue and after googling a while I didn't find a reliable answer. After giving it some thoughts, I figured that the mirrors have the same data and so we could compare some part of it. NOTE: BE CAREFUL, IF YOU HAVE MORE THAN 2 DRIVES WITH THE SAME CHECKSUM YOU ARE PROBABLY COMPARING EMPTY DISKSPACE, CHOOSE ANOTHER OFFSET (skip option). With ...

You can use the --scan option to show the list of devices: c:\>smartctl --scan /dev/sda -d scsi # /dev/sda, SCSI device /dev/sdb -d scsi # /dev/sdb, SCSI device /dev/sdc -d scsi # /dev/sdc, SCSI device /dev/csmi0,0 -d ata # /dev/csmi0,0, ATA device /dev/csmi0,2 -d ata # /dev/csmi0,2, ATA device /dev/csmi0,3 -d ata # /dev/csmi0,3, ATA device /dev/csmi0,4 ...

During the installation you have a partition menu and at some point you create the partition where you want to install Windows to, right? As far as I remember, at the point where you create the "C:" Partition, the "system reserved" is also created and you can see it in the menu. If you now delete both partitions and create a new "C:", no "system reserved" ...

By external drives I am assuming you mean USB drives. Firstly, this is technically not feasible because Windows loads USB drivers much later in the boot process than other storage drivers. Also, USB is a higher-layer protocol stack than the rest of the storage subsystem. This is why USB devices can be easily redirected into VMs without causing problems ...

RAID 5 would make it significantly easier (and arguably cheaper) to expand your storage later. Are you trying to hit any specific performance characteristics? Raid 5 - Pros: Easier expansion (Put the new disk in and tell it to expand. It essentially does the rest.) Cheaper expansion (You can expand 1 disk at a time rather than have to stripe sets of ...

Does that mean Windows doesn't support creating spanned drives on removable drives ? Correct. Spanned drives are an option of dynamic disks. From https://msdn.microsoft.com/en-us/library/dd163552.aspx : Note: You can't use dynamic disks on portable computers or with removable media. And the follow-up question: Is there a way to bypass ...

I haven't converted from RAID 1 to RAID 5 in BTRFS, but I have done other BTRFS conversions, and according to the documentation they are all equally easy. It is as simple as btrfs balance start -dconvert=raid5 -mconvert=raid5 /mnt It is not difficult, but it will take some time (many hours). Yes, RAID5 is still marked as experimental. Per the most ...

The main reason is that performance will be degraded since the controller may be having to do many re-reads to get failing data.

You aren't going to be able to just "switch" RAID modes like that, as the array would need to be recreated/reinitialized. Easiest: Reduce data so it's small enough to fit on the RAID1. Get an external drive that's large enough to accommodate your data (and then some). Perform full system backup to external drive. Destroy RAID10. Remove 2 drives. Create ...
