hdd means Hard disk but wht is raid.
I Am Writing It Down Below Point by Point For Easy Understanding...
1) RAID Basically Is An Acronym Which Stands For Redundant Array of Independent Disks.
2) Normally Slightly Expensive New Motherboards Offer Built-In Onboard RAID.
3) Basically It Is A Configuration Of Multiple HDDs (More Than One HDD) Which Was Earlier Used In Servers By Corporates, But Now It Can Be Used By Practically Everybody Who Desires.
4) RAID-0 Is Basically Spreading Out Writing Of Data Over Mutliple HDDs, But Doesn't Have Fault Tolerance (Personally Not Recommended)
5) RAID-1 Is Basically Config. For Mirroring & Duplexing Of The Data, A Technique Which Employs Data Being Written To Both Disks Simultaneously. This Way If One Of The HDD Fails, The System Can Instantly Switch To The Other HDD Without Any Loss Of Data.
6) RAID 0+1, You Don't Need Worry or Know About It, But Simple Explanation For It Is That Where Two RAID-0 Is Created & RAID-1 Mirroring Is Created Between Multiple HDDs.
Hope The Above Answers Most Of Your Questions About RAID
