    What disk space do you see in C drive with the above config?Should it be 100+gb ?for my case it shows 210+ gb space left, is that normal for raid 0?

    2x128GB means there are two 128GB SSD modules in a RAID0 array. Since your computer sees them as 1 combined volume in which files parts of files are written on both simultaneously (as in 1 file is written once between the two drives, not 1 file written once per drive as in RAID1) you have 256GB total (minus the 1000MB/GB the company uses vs. the 1024 MB/GB your computer sees)

    I think OP is getting this confused with RAID1, where you only see half of the space.

    RAID 0 used alone shouldn't be called a RAID at all, because there's no redundancy (the R in RAID). When combined with RAIDs, like in RAID 10 and RAID 50, the result is a RAID, but not when used alone.

    It's just plain striping, which increases sustained read/write speeds at the expense of failure rate.
