SSD best practice

[Pete42]

Hi

 

I have 6 x 2tb SSD and would like to build a low power / low noise unRaid server, but reading this forum and internet in general am confused at what *supported* options are available…

I’m happy with single parity drive and have a UPS already.

 

I read that a possible way would be to setup an array with a single disk, then a pool with the 6 x SSD, but that the only supported pool type is RAID1, so capacity would be the same as 2 x 2tb, with a load of redundancy!

Is single parity supported by unRaid; i.e. RAID5 on a pool, as a native option - not via CLI work-around?

 

I also looked as ZFS plugin, but looks to be very CLI driven and not formally supported…

 

Looking for supported options, as I just want to set it up and periodically run updates.

i.e. I’m looking for a Synology (supports RAID5 SSD out the box) on the cheap

 

Many thanks

Pools are not limited to RAID1.

It defaults to RAID1, but once the Pool is built, you can balance it (in the GUI, no CLI required )to whatever BTRFS profile you can support with the material. In your case, probably RAID5/6 or RAID1c3/4 etc.

Thanks for the clarification.

 

Any idea if using SSD in this way to provide primary storage is common/recommended, or is it better to wait until ZFS is available for native SSD support?

 

So far unRaid ticks all the boxes except the use of SSD for primary storage…

 

Many thanks
