As your array is already set there is not need to start from scratch and make a RAID 1.
In any case the SHR internally configures the two disks to work exactly like in in a 'pure' RAID 1.
As far as I understand the RAID migration feature: yes, you will be able to expand your RAID to, say, 3TB later on. During expansion, you have to insert one 3TB drive first and once the RAID rebuilt, the other one and rebuild again.eadrian75 wrote:My ds211j is in the mail, along with two 1.5TB HDD. Correct me if i'm wrong, but if i decide to set up using Raid 1, then am I more or less stuck using 1.5TB drives for the life of my unit? Or do i have the option to rebuild the array by inserting a 2-3TB HDD in one of the slots. Then perhaps, remove the remaining 1.5 and replace that with the second 2-3TB HDD.
Would it just be easier to set up using Hybrid if my intentions are to one day increase the size of at least one of the drives (preferably both)?
Please advise, thank you.

Synology wrote:Fast SHR Volume Creation
Building a new volume from the scratch always takes a long period of time, and in most cases you wouldn’t be able to start working while the process is still going. It’s not the case if you used Synology Hybrid RAID (SHR) to build a new volume. The SHR has been greatly enhanced so that now it’s 95% faster to create a volume. For example, a 10 TB volume usually requires approximately 9 and a half hour to complete the entire process, now it only takes around 30 minutes.
The SHR prioritizes file system in the volume building process. As the file system is being built, the rest of the process will take place in the background to allow users to start storing, editing and moving files around immediately.
