Storage Spaces suggestion - better with one big pool or two small pools?
I have 8 x 4TB SATA drives (hot swappable) and want to configure Storage Spaces for them but have been wondering if I should create two pools and each has 4 x 4TB with mirror or just one pool with 8 x 4TB with mirror. What is your suggestion?

What are your requirements? Especially how resilient should that RAID be against drive outage? How many drives may fail before the critical one?

That is just a general question about whether keeping all drives in a pool or separate them into two pools. Which one is better?
What's the intended purpose for the storage?
I suggest a RAID 6 setup running with a RAID controller with flash-backed cache as opposed to Storage Spaces software driven resilience.
A SATA drive will yield about 250 IOPS and about 150MiB/Second in performance in a RAID setting. Not so much in Storage Spaces unless set up with a three-way mirror but that means only 33% of storage available and then column counts versus drive counts need to become a consideration.
Long story short: Run with RAID.

Storage
Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
