Oh, you mean the typically USB drive. Ok, sure, I can do it, thanks for the hint. But still, would this: ... be ok to host data and cache? Or what is recommended?

I see, thank you. Unfortunately, I don't have another old flash drive, only these three I mentioned. How would you setup data, cache and parity with these? Is Parity even needed, regarding the Synology Backup? Could I go with, e.g.,: - 1 TB NVMe for Data (KIOXIA) - 1 TB NVMe for Cache (Samsung Pro) - 512 GB SSD for Cache I just don't understand what to assign to which hard disk.

/push I would really appreciate some guidance so I can finally get started - thanks!

I am new to Unraid and have already read through many posts. Frankly, however, I am quite overwhelmed and do not want to make mistakes right at the beginning, hence the question. Unraid runs on a Lenovo M720q server, on which unfortunately only two NVMe and one SSD (SATA) can be installed. So the server has the following three hard drives: - Samsung SSD 980 PRO 1TB, M.2 2280 - KIOXIA BG5 Client SSD 1TB, M.2 2230-S3 - SSD with 512 GB (Noname) How should I best set up Unraid with the three hard drives (data, parity, cache)? Using Unassigned Devices I included my Synology NAS (which has 4x 4TB HDD) as SMB share; but there I'm not sure yet how to use that. Can I use this storage? Otherwise, I would just run backups to the NAS, if possible (via CA Appdata Backup?). The NAS is backed up daily (to another location). At this stage, I would rather run services on the server to make my life easier. I'm sure there will be relevant data, but it should be backed up by regular backups. So it would not be dramatic if, in the worst case, everything would be gone. But this is only further information. Thank you very much.

I see. Would you be willing to write more details about the installed hardware and your implementation? Sounds very interesting. I'm still going to try the Lenovo box, but having an alternative up my sleeve is certainly not bad. Thanks.

@semicole Have you found a solution to the problem? I am currently in the same situation: I have a Lenovo M720q, but it only has room for two SSDs (one 2.5" and one m.2 NVMe). I still have 4x4 TB 3.5 HDD lying around. How should I build Unraid with parity, cache and data disks?
