New setup

Post by alessiofv »

Hello everybody,
I would like to expand the capacity of my TS-451+ but I have just discovered that it is not possible to exceed the total amount of 16 Tb.
My current configuration is the following:
- volume 1: two 4 Tb disks managed as JBOD for multimedia archive;
- volume 2: one 4 Tb disk managed as static volume for personal documents;
- volume 3: one 500 Gb disk managed as static volume for documents backup.

The idea is to switch the 500 Gb disk with a 4 Tb disk and create the following configuration:
- volume 1: two 4 Tb disks + 50% of the other 4 Tb disks managed as JBOD for multimedia archive;
- volume 2: 50% of one 4 Tb disk for personal documents;
- volume 3: 50% of one 4 Tb disk for documents backup.
The chart that explain the configuration.

Do you thing this configuration is correct and safe (I am not interest in backup the multimedia volume)?
How can I create this configuration in QTS?
Many thanks to everyone.
Regards.
Alessio

Has nothing to do with 16TB, none of the disk modes you use will support growing (single disk, jbod)

Only if you use RAID1+ you can swap disks and grow the volume.

So either switch to RAID1/5/6/10 or start from scratch every time you want to expand disks or have drive issues.

I would say 4*4TB in RAID5 with external backups should be your setup, no need for SSD's

Your point is clear but, I don't want to lose capacity, as RAID 5 do.
Also, is not relevant to me lose the multimedia archive, what is very important is to save my personal documents and for this reason, phisically segregate the data on two different disks.
Do you think the best way is not to have the backup on the qnap but only externally?
Thanks

As the NAS handles everything in shares, physical segregation is not needed

no matter if you keep 5 separate single disks or one large raid array, shares are accessed and secured exactly the same

A backup of data on the QNAP is not a backup (disks are inaccessible if your have a hardware failure) backups are always done to external USB/NAS/Cloud/etc locations
