Hi all,
looking to upgrade one of my private servers to backup family computers and smartphones.
As it turns out that are more than 15TB to backup... Thus I was thinking of using 2.5" SMR drives.. or I have to go to SSD, which will be quite expensive as I am bound to the 2U Rackspace and the free 2.5" SAS 12G slots.
Initially it would be a long write of about 10TB of data.
Smartphone push new data (picture,chats,etc.) when they have new data.
Pool raw size would be about <30TB and initial filled with 10TB from the current system. Additionally about 5TB from other systems, which are not backed up yet.
Data growth is about 1-2TB per year.
Would just be another pool I would add the my TrueNAS.
Currently looking at: Seagate BarraCuda Compute 5TB, 2.5", SATA 6Gb/s (ST5000LM000 which are Shingled Magnetic Recording (SMR), Drive Managed SMR
What are your ideas regarding those disk?
Planned layout:
2x 800GB SAS as Meta Data
2x 480GB SAS as SLOG
3x RAID Z2 of 4 those 5TB disks.
Another option would be going SSD, as I am limited to 2.5" slots. This would lead in way higher costs.
I have the SAS drives and would only need to acquire the HDDs.
If going SSD I would pic the Micron 5210 ION 7.68TB, SATA (MTFDDAK7T6QDE-2AV1ZAB) oder Kingston DC450R Data Center Series Read-Centric SSD 7.68TB, SATA (SEDC450R/7680G). And 6 SSDs as a big RAID Z2 pool, with those SAS SSDs for SLOG added at least.
Another option would be going for just 2.4TB SAS HDD and picking the Seagate Exos E 10E2400 2.4TB, 512e, SAS 12Gb/s (ST2400MM0129).
With those I would need to make use of every free 2.5" slot. As I still have 17 slots free, I would go for with 17" drives and a single big Z3 with one hotspare. That would lead to the same raw capacity but against any sence having 16 drive within one RAID Z...
Any suggestion or ideas regarding this?

- Costs for the HDD pool with SMR drives is about: 1500€
- Cost for the SSD pool would be about: 5800€
- Cost for the HDD pool with CMR SAS drives is about: 4300€
Any suggestion or ideas regarding this?
