How to Use Windows 10 – Storage Space to Combine Multiple Physical Harddrives?

I have 2 old Hard drives from old PC: 1.5TB and 1TB. They are SATA III HDD (6GBps, 7200 RPM, 64MB Cache). I want to use these drives to store some videos, photos and I don’t want to split the files over two hard drives (managing two hard drives separately). Instead, it would be perfect if all videos/documents are stored in a single, big, virtual storage.

HPZ800 has 4 SATA drawers. So you can easily plug and play.

The Windows 10 Storage Space is made for this purpose. You can actually combine multiple physical hard drives into a single virtual, huge disk that can be expanded when space is used out. The storage space can be seen as the software RAID implemented on Windows 10.

Type in ‘Storage Space’ in the start-up menu, that will lead you to the Storage Space configuration.

storage-space

Click the [Create A New Pool and Storage Space]

manage-storage-spaces

Select the Hard drives you want to be in the Pool. Please note that any drives you select here (including formatted) will be wiped so all existing data will be lost.

select-drives

Select all drives and the OS formats all of them before combining into a pool.

Simple-No-Resiliency similar to RAID 0 where all data is evenly stripped across two or more disks. This improves the disk read/write performance but does not have any redundancy so that data is gone when one of the disks is failed.

simple-no-resiliency

Two-way-mirror – similar to RAID 1 – where all data have two copies on both drives. The data is mirrored so that it can be recovered if any drive is falling. It may have slight impact on the disk write speed. You would need at least two drives for using this.

two-way-mirror

There are other options such as Three-way-mirror where data is copied three times .. Since the data I want to store is not critically important, and I also trust the quality of the HDD, so I pick the first option – RAID 0.

summary

storage-space-drive

It is wonderful that I can expand this virtual HDD once the space is used up, which I cannot do in traditional HDD.

Performance Comparisons

The C drive, master HDD is also brand of Seagate. The three HDDs are all 7200RPM, 64MB cache; so they should all perform similarly if measured individually.

I run the winsat disk -drive command to measure the performance of the master C drive and here is what I get.

We can see that the read speed is obviously faster with the storage space. The write speed is slightly slower, but it should not be a big problem.
