Hi,
I recently purchased an Asustor NIMBUSTOR 4 AS5304T, with 3 16TB SATA drives and a single 64GB SSD drive, I have set it up as a single volume RAID-5 using the 3 16TB drives with the SSD as a read-cache drive. However, I have noticed that some of the apps running on the system will periodically access the drives, meaning they never hibernate, putting up the energy usage of the system by about 3-4 times.
I am thinking therefore that it might be better if I used the SSD as Volume 1 of the system and had the RAID-5 array as a second volume (I don't think I really need the SSD cache as the system will mainly be used for media streaming, so the regular drives should be plenty fast enough).
So firstly, does anyone know if this is likely to help with the drive access problem?
And secondly, can I do this by resetting the system and setting it up again with just the SSD installed as Volume 1, and then adding in the RAID drives to create a new Volume 2 with my data intact? Obviously realise I'd have to re-setup all the various apps etc. but as the system is pretty new that shouldn't be much work, but I'd prefer to not have to copy across the data again as it is about 20TB, so it takes days! Luckily I still have the original data, so I could just clear everything and start again, but I'd prefer to avoid that if I could.
ASUS support site says you can place existing drives into a new NAS and it should work, but think that is a case of putting them in and using them as the same volume, so not quite what I want.
