Yeah, if you add a 2TB disk and configure RAID with the 250GB disk, then your RAID 1 will only be 250GB, meaning you will waste 750GB of disk 3. In order to use disk 2 for ANYTHING, you will need to first UNassign it as a hot-spare (hot-spares are reserved as standby drives for RAID arrays and are not visible to the OS).  Unassigned, it can be used as a standalone, non-RAID disk, or  you can configure it in a RAID 1 (Integrated Mirror - IM) with a second disk. If you want a 2TB disk with maximum compatibility and reliability, look at something like this: [URL] If not: [URL] [URL]
Hello support team, I'm working with a Dell PE T310 and is using running a windows 7 OS. The controller card is a SAS 6 iR, configuration is RAID 1 and reaching its max capacity.  I want to add more storage without losing any data. The Controller Bios configs is listed below:  1. How can I add more storage without losing any data? 2. Can I use drive (2 - ATA) that's not being used in the Raid listed for HOT spare (not seen in Disk Management) for RAID 0 considering that the 4 drive bay is empty at this time or if it should/could be used for another HDD and configure another RAID 1? which leads to my next question: 3. 3 drive bays are being used, the 4 HDD bay has only the metal mesh. Can I add another HDD and configured for additional storage?
