RAID 0 Help

[Rezalis]

So I have two identical Samsung 850 EVOs both 500gb. If I were to RAID 0 them, would I get approx twice the speed and the full capacity of both drives (1tb)? Or would I just get twice the speed but only 500gb of storage? I also have an operating system and programs installed on one drive. Is it no longer possible to RAID 0 them?

RAID 0 gives you the space of both drives, but no higher speed. RAID 1 gives you redundancy in that if one drives fails, all your data is still stored on the second drive. RAID 5 does both.

Before going any further, please watch this video provided by LTT.  It may explain a little further than I can about Raid0 and whether or not a Raid0 using SSD is practical.  IMHO, I don't believe that using SSD's in a Raid0 will grant you any advantages.

RAID 5 requires three or more drives and is slower than RAID 1 (and obviously RAID 0) due to parity overhead. 

 

@Rezalis If you want to put two drives into RAID, then you have two options, RAID 0 and RAID 1. RAID 0 will theoretically double the speed (but also double the risk of all data being lost) and give you the space of both drives in usable space. RAID 1, which will give you redundancy but will give you a total capacity of only one of the drives. Both require the drives to be formatted, so you would have to completely erase both drives and then reinstall the OS.

Is it possible for me to just combine both drives into 1 without a raid config? It wouldn't increase the speed, but I just want both drives to act like one in file manager. I also do not want to reinstall the OS. The 550MBps I get is more than enough for me lol.

Not that I know of, I'm pretty sure RAID is the only way to do this.

You could set the two up as a Spanned volume, which would basically use one drive as overflow, but the problem with that is you would have to fill up one before the other, which isn't ideal either.
