Drive compatibility by type and size

[Ganesh]

Hi Guys, Please pardon me if its a stupid question. I am looking to convert my old PC to a new NAS (1st time setup and have no experience with setting up NAS before). I read that the drives I can use should ideally be same size, else the used space in the pool will use size of smalled drive for all drives which means that I should ideally have drives of same or similar size. However, are there any contraints on type of drives? i.e. can I combine 1 2 TB HDD with 2, 2TB Sata SSDs and 1 2 tb NVME SSD? Thanks in advance.

You *should* be able to do this, to my understanding, but that is asking quite a bit from software that is still in beta. I've seen others post that they were able to do this and others that struggled. Might be a good idea to search the forums and see what others have experienced. Good luck!

I would not recomend doing that.
You can, but you should NOT.

Here is a thread form the truenas scale forum: https://www.truenas.com/community/threads/mixing-2-ssd-and-2-hdd-in-same-pool.115280/

HexOS is build on top of TrueNAS Scale so if you find something over there it should apply to the underlying truenas but may not to the hexos part.

 

But mixing drives will cause you a lot of issues unless you know how to move metada to a cahced pool or the like.

Set up an HDD pool and a SSD pool, it will make like more convient for you.

Thank you guys. Very much appreciate your responses. I think I will setup with same type of drives to reduce hassle.
