disk size

Hello, Not sure where to post this but I guess this is related to amtm stuff. I have 1TB spare (SK Hynix BC711 M.2 2230) sitting around for ages. Finally bought enclosure for it. Now, what do I do with it and how to utilise it. Currently AX86U have SanDisk 64GB 3.2 Gen 1, and read about SSD...

Bought a new WD MyBook with 6 TB disk space. RT-AC68U would not recognise it, and I thought it was because of documented limitations, max. 4 TB: http://event.asus.com/2009/networks/disksupport/ Moved the disk over to my NAS, which said it was formatted as exFAT , not ext4 , so it made sense...
