Best settings.......

[cattledog]

Hi all, Before we start I would first of all like to say thanks to this Freenas community for a great job well done....:)
I have over a Tera of movies and photos that I would like to keep safe, this size is growing on a daily basis so I went out and bought 6x3tera wd red hdd.
As these are family photos I have decided to go zfs for more safety.
What is the best way to set up ie:RAID-Z1, RAID-Z2 or RAID-Z3, Stripe or maybe Mirror?
Cheers in advance.....

Suggest seeing Cyberjock's guide, which explains some of the advantages of each strategy.

I would like to keep safe ... Stripe

Not this.

Only you can decide what "best" means for you in terms of trading performance vs capacity vs reliability. Do read that guide, the knowledge will serve you well.

I expect you'll end up with the ever-popular 6-disk RAIDZ2 single vdev layout.

Maximum recommended usable data space: 7.711 TiB (8.479 TB)
looks good

Please use the link to the thread instead of the application itself because it changes each time I make a modification. This link is to a very old version, for example the current link is https://jsfiddle.net/Biduleohm/hfqdpbLm/10/embedded/result/ thanks ;)

I'd do RAIDZ2 with the following caveats:

• Purchase a system that supports ECC RAM.
• ZFS is not a substitute for having a backup.
• If you only have one copy of your data (even if it's on a FreeNAS server), you have no backup.
• The fates do not look kindly on people who do not backup their data.
