Quick Question - RAID 0

[Aleksbgbg]

If I have an SSD, fill it up and then decide to add another, can I run them in RAID 0 and have some sort of program copy over the files and do all the math to make it as if it was RAID 0 the whole time?

No, when you stripe a raid, all data on both drives is completely wiped. You would need to clone SSD1 to a THIRD drive, stripe the raid, clone drive 3 back to raid, expand the partition, etc.

Cloning - is this some sort of option or do you just copy it and paste it

 

Sorry, I really don't understand this very well

If it's just data, you can copy and paste.

 

If it's your OS drive, you need to "clone" it or make an exact copy, so it still boots, etc.

 

You can use programs like Ease Todo backup free and a plethora of others via Google.

So:

- Clone to 3rd drive

- RAID the drives together

- Install OS

- Clone back

 

Right?

If the SSD in question is your OS drive, then you just clone back from drive 3 to the Raid. It'll replace anything on the raid, so installing the OS will just be a waste of time.

 

(Note: You can clone your OS drive to the third drive while in Windows, but you can't clone back because that'd be erasing Windows while in Windows. For cloning back, you'll need a Live CD program to clone, so once you set up the Raid in BIOS, boot to the Live CD to clone disk 3 onto the raid.

Some raid cards support changing the raid level without losing data. BTRFS also supports this(linux only).
