Unraid Calculator

So some or most of us, i know the calculation is easy. But fireguard I might as well try to fill the void of the old calculator that never seems to load for me.

Please correct the calculator, it is not usable as is, the number of parity drives is not limited to 2, and it allows invalid configurations to be entered. If someone is relying on it for accurate results they will be disappointed when Unraid won't allow them to configure their array as depicted on your page.

If you first fill out the Number of Drives section to reflect number of parity and data drives and then fill out section 2 for the sizes and then calculate....it works....

If you don't see what's wrong here, you just need to take the calculator down. It's not usable.

 

Unraid is limited to 2 parity drives, and no data drive can be larger than either parity drive.

Windows has this feature built-in.

I was about to say, why even need a special calculator.  Unraid core feature is any mixture of sizes and as long as you can add you know the size of your array.

The site in the solution, https://unraidcalculator.com/, seems to no longer be functional.

No doubt the author followed this advice.

What do you want it for anyway? Just add up all the data disks in the array, leaving out any disks you will assign to either parity slot, and that is the capacity of the parity array.

And even that is just a ballpark estimate of how much space you can actually use, since there will be some filesystem overhead, and you don't want to get any disk too full anyway.

 

One of the great features of the Unraid parity array is how easy it is to expand, by upsizing/replacing disks and/or adding disks.

I'm new to unRAID. I'm migrating away from a Drobo 5N2 NAS. I guess I was looking for something Drobo's Capacity Calculator, as seen here:

Looks like I won't need it, though. Thanks for the advice!
