[Enquiries]

Hi - naive question I’m sure. I have a DS418play originally with 4x3 TB disks. Due to budgetary constraints I bought two 12TB disk and having installed them 1 by 1 with a repair and an expand after 2 I now have 2 x 3tB and 2x12tb giving me about 15TB so I assume Synfs (can’t rem name) has mirrored them. Can I add another single 12TB later or will I have to do both. If I can bring it to 24TB I don’t mind removing the last 3tB disk is that in fact my way forward put in another 12. Repair it and then ask it to remove the final 3tB disk having a spare bay for future expansion. I don’t have enough cloud storage for a complete backup and start again

Many thanks Frank

Yes, you can replace only one disk and see benefits already. Here is a tool you can play with https://www.synology.com/en-us/support/RAID_calculator
