Hey TrueNAS fellow people,
I would like to start migrating my main TrueNAS server to all-flash in the very near future and wonder what recommendations there are regarding the SATA SSDs? That it should definitely not be consumer grade disks (more unreliable) is of course out of question.
Use case is as follows:
Storing all kind of data (documents, audio and video), nothing really stands out
The following disks are currently on the short list:
In terms of price, the difference is negligible. Any advice, comments, tips and/or suggestions are very welcome.
Have a nice week and thanks for taking time to read through my posting.

- Possible pool layouts
Striped mirror
pro: resilvering is faster and less stressful for drives
con: no more drive fail during resilver process, or
RAIDz2
pro: another drive can fail while resilvering
con: more stressful for each disc while resilvering is in progress
