Storage Spaces in Windows 10
Applies to: Windows 10
Storage Spaces helps protect your data from drive failures
and extend storage over time as you add drives to your PC. You can use Storage
Spaces to group two or more drives together in a storage pool and then use
capacity from that pool to create virtual drives called storage spaces. These
storage spaces typically store two copies of your data so if one of your drives
fails, you still have an intact copy of your data. If you run low on capacity,
just add more drives to the storage pool.
You can use a variety of types of drives with Storage Spaces, including USB, SATA, and SAS drives.
How do I create a storage space?
Add or connect the drives that you want to group together
with Storage Spaces.
Go to the taskbar, type Storage Spaces in the search box,
and select Storage Spaces from the list of search results.
Select Create a new pool and storage space.
Select the drives you want to add to the new storage space,
and then select Create pool.
Give the drive a name and letter, and then choose a layout.
Two-way mirror, Three-way mirror, and Parity can help protect the files in the
storage space from drive failure.
Enter the maximum size the storage space can reach, and then
select Create storage space.
Should I create a simple, mirror, or parity space?
Simple spaces are designed for increased performance, but
don't protect your files from drive failure. They're best for temporary data
(such as video rendering files), image editor scratch files, and intermediary
compiler object files. Simple spaces require at least two drives to be useful.
Mirror spaces are designed for increased performance and
protect your files from drive failure by keeping multiple copies. Two-way
mirror spaces make two copies of your files and can tolerate one drive failure,
while three-way mirror spaces can tolerate two drive failures. ... When a mirror space is formatted with the Resilient File
System (ReFS), Windows will automatically maintain your data integrity, which
makes your files even more resilient to drive failure. Two-way mirror spaces
require at least two drives...
...Parity spaces are designed for storage efficiency and
protect your files from drive failure by keeping multiple copies. Parity spaces
are best for archival data and streaming media, like music and videos. This
storage layout requires at least three drives to protect you from a single
drive failure and at least seven drives to protect you from two drive failures.
I bought 2 more 1 TB Seagate drives and set up a storage space using those 2 new drives. I thought the motherboard had only 3 SATA ports so I stuck with 3 drives but each one was a double port (they need straight connectors on the cable to use 2 because they are stacked ). I didn't expect that the storage needs unformatted drives to work. I didn't format them so I was ok. I set them up as mirror drives so both 1 TB drives act as less than 1 TB drive D.I am not using much so far and I have 3 SATA ports left. Once they were set up I cut and pasted my documents & picutures into the D storage space. I think I'm covered now.
