Hey i want to build an unraid storage server with 12 x 10TB Drives.

What is the best way to setup the drives i want to use 2 drives as parity and I will use 2 x 1TB ssd's as a cache pool. 

So what type of Read performance can i expect from Unraid?

 

I need really good read speed performance so is it possible to get read performance similar to something like a RAID 10 setup? If so whats the best way of configuring it?

 

 

UnRAID does not stripe data so the fastest read speeds are going to be constrained by single disk drive read speeds.   If you want higher performance then unRAID is probably not the right product for you to be using.

Hey,

 

I saw in the Linustechtips video he was getting much faster performance, so how was that achieved?

Writing to the cache pool.

ok

so that means that there are no benefits for read performance?

Only if also reading from the pool.

OK, 

so i am new to Unraid but i think i am missing something.

I thought the cache pool was only for writing data. So does it cache data from storage or only reads back data that is in the write cache?

So if the write cache is flushed to storage then there will be no read performance benefits right?

 

The cache can be used in many different ways, but yes, usually for data transfers it's used to cache writes and then the data is moved to the array by the mover, mover runs on a configurable schedule.
