Yes, I considered full SSD option, but it is very expensive. Using intel

If you plan to scale up in the future you could consider the following config
to start with:
Pool size=2
3 x servers with OS+journal on 1 ssd, 3 journal ssds, 4 x 900 gb data disks.
It will get you 5+ TB capacity and you will be able to increase pool size to 3
at some point in time.

I am sure you already consider the "full SSD" option, did you ?

Why would you put os on ssds? If buy enough ram so it doesn't swap,
about the only i/o on the system drive will be logging. All that'd do is
wear out your ssds, not that there's much of that going on. (Our server

Cabling problems, controller failure, intermittent disconnects,... I've seen it
all, who knows what's going to happen to yours :)

thanks for your resonse. This is true, a single SSD failure also
My vision of a well built node is when number of journal disks is equal to
number of data disks. You definitely don't want to lose 3 journals at once in
case of single drive failure.

I want to use a replica count of 3 in the pool and the idea is to buy 3
