How to check the storage details of my computer
I bought a new computer with the storage: Dual: 1 TB*2 / 2TB RAID0 (2*1 TB), but I can only find a "C: " with 1.83 TB in my computer. Shouldn't there be two drives? Or, what's the difference between Dual and Single of storage?
I'm a little confused about the hardware techniques of computer, grateful for helping me!

RAID 0 stripes the data over both drives and appears as a single 2T volume (the size discrepancy is between the manufacturer definition of a gigabyte (10^9 bytes) and the OS that uses the binary definition (2^30 bytes). The drive will appear 93% of 2T total, which is what you see.
If you want two separate drives -- a good idea, since a RAID0 array means that if either drive fails, you lose everything on both drives -- you will need to break the array, set up the two drives and reload the operating system, drivers and applications once that's done.

@ejn63 Thank you very much! I think maybe I got it... Like, although it has two drives, it appears as one. But by the way, I have a very tiny question: If so, what's the differences between the Dual 1TB*2 & Single 2TB? Because it seems like they appears same in the computer.
Thank you for answering my question!!!

A single 2T drive is exactly that -- one drive, one volume.
A RAID 0 array is two drives, each containing essentially half your data. In theory, it should be faster that way, but in practice it is not -- and bear in mind that a RAID 0 array depends on two hardware elements. If either drive fails, you lose the contents of the entire volume.

@ejn63 Oh...so it may not better than a single drive in practice....
Whatever, thank you so much!!!
