I'm hoping someone here has some experience with Storage Pools with a mixes assortment of HDD's.
I am going to configure an old PC with Win 8.1 and planned to use Storage Spaces for a mirrored backup. But all the articles I read focus on creating the storage pool and the selecting an option (none, 2-way mirror, 3-way mirror or parity).
My question is how to build the pool for the 2 way mirror.
I have the following 3 drives that I planned to use in the pool.
- Seagate ST6000NM0024 6TB (no, I didn't drop $600 on this thing. It came my way through other, legit, means.)
- WD Green WD40EZRX 4TB
- WD Green WD20EZRX 2TB
Now for my questions:
- If my goal is to have 6TB of storage in a mirror, does the pool need to be created as a 12TB or 6TB?
- Will the difference in speeds be a major impact or barely noticeable?
- Am I better off skipping Storage Pools and instead configuring something like SyncToy to copy files from the 6TB Seagate drive to the other WD Green drives for an instant backup should something happen?
Any other pitfalls I should watch for? I was looking at Storage Spaces as a low cost way of having something similar to RAID. I don't have the funds for a RAID card or time to learn about RAID, I saw Storage Spaces as a fairly quick way of building a ton simple storage solution with some type of redundancy for my use at home (music, pictures, movies and document storage).

It uses thin provisioning so make it whatever size you wish, storage spaces will handle the tech stuff and tell you when you need to add more drives to keep the redundancy alive.
I have 3 x 2TB, 2 x 1TB drives in mine and have a mix of volumes (some 2 way and some pairty), I just add more drives as I'm told to.
Also using this as a backup platform is fine, but don't consider live data on here as being backed up - its not, its merely redundant. If you delete a file or things get corrupted you do not have a backup.Go to the full post
