Disc to Readynas 524
Hi all I have a Readynas Ultra 4 and four Seagate st2000dl003-9vt166 2TB discs and I am using it at home for backing up my photos and other thing. The Ultra and Seagate discs are almost 10 years...

Hi StephenB Thank you for your reply. Maybe I should go for 2 WD80EFZX discs and leaving 2 slots open. ... And in future when 10GB+ discs become more affordable I can use these in slot 3 and 4. Regards PaalThat's a reasonable approach.

I have to use Raid-1 I guess?Just use the default XRAID. That maintains single redundancy, and can handle mixed sizes (as long as the new disks are bigger than the existing disks).
Under the covers, XRAID will use RAID-1 with two disks. If you go to 2x8TB + 2x12TB, it will convert that to a 4x8TB RAID-5 group and add a 2x4TB RAID-1 group (to use the extra space on the 12 TB disks). These are merged into one volume/file system, so all you'd see is a 28TB volume.
It is important that these WD discs must be working for at least another 10 years :)
