Yeah so basically I was wondering if 2x500GB HDDs with RAID are the same as 1TB HDD ?

If you're using RAID 0, yes or RAID 1 no.

Failure of either drive in a RAID 0 configuration will result in the loss of all data on both drives.

RAID 1 is a mirror array, that effectively duplicates the two discs, but is never larger than the smallest disc in the array.

What does it mean when a website says the HDDs have "RAID 0, 1, 0, 1.5" ?

simpleWiki RAID

I find even standard Wiki on stuff I sort of know a bit obtuse sometimes.
