I apologize if this question has already been answered. My Cloud 2TB has reached capacity; I tried connecting a 2 TB SSD to the USB on the back of the Ultra EX2 series to expand the capacity without any results in getting the drive to recognize the additional space. After doing some researching, I found I can add extra space by extending the drive by changing the RAID setting to expand. How long should the unit take to expand the drives? Currently, I have solid red lights on both power and drive 1. The Ultra EX2 has been in this state for the last 12 hours. Thank you.
Get a NAS with 4 disks which can use large disks and have space galore with a modicum of reliability’
4 disk use RAID5 to prevent data loss
This is an important issue.
Adding a 2TB drive via the USB connection does not increase raid capacity. The NAS will treat the new drive a separate non-redundant share. It will NOT use the USB drive as additional storage as part of the NAS raid system. How can it. . . the USB drive is designed to be removable.
With a USB drive attached to the NAS, you can run backkup programs to move date from the NAS to the USB drive without bogging down a PC.
Now, if you are getting red lights on the NAS - - → that is a separate problem. It means the NAS has an “issue” and you need to make an immediate backup (if you don’t already have one). Note that 95% full will trigger the warning on the system.
RAID is no panacea to a drive failure. Red lights is a warning sign that disaster is imminent. 4 disk Raid is just more “space efficient” than a 2 disk raid. . . you still have to fix issues if a single drive fails (i.e. replace the drive)

I prefer 8 disk NAS to have more capacity
