tmoran000 Posted September 8, 2021 Share Posted September 8, 2021 My array is made up of SSD's however I do not have a parity drive in yet so my question is 2 fold. 1) am I truely getting ssd performance out of the ssd's when in the array vs mechanical HDD. and 2) If I am getting a performance boost by using SSD would be using a HDD for parity restrict that performance down to HDD level because of it? Its just that a 8tb SSD would be like a million dollars so to get a HDD 8tb is reasonable. Quote Link to comment
itimpi Posted September 8, 2021 Share Posted September 8, 2021 What is the largest drive in the current array? The parity drive does not need to be larger than tha.t. when you add a parity drive you should assume that write performance will be constrained by the parity drive so you do NOT want to mix HDD and SSD in the main array.. it is more typical to have HDD in the main array and SSD in pools external to the main array. 1 Quote Link to comment
