Raid with 2 SSD's

post #1 of 11
Thread Starter 
Hi there. I am very new to this so please excuse my ignorance.

I am wondering if there is a way to RAID two 240GB SSD's, so that they work as one, 480GB drive. I've read some about striping??? But I'm not sure if this is what I need to do or what it really is. So I'm clear, I want to take my one current 240GB SSD, and add a second, making one big 480GB SSD. It will run my operating system plus games. I have a bigger HDD for storage. I don't want RAID 0 or anything like this. I just want to add two drives together to make one. Thanks for any help anyone can be.

Wait,

You just described a RAID-0... but you don't want a RAID-0? I mean, there's also JBOD, which will essentially attach the two together, but has the exact same reliability issues as RAID 0, without the performance boost.

I guess my understanding of RAID 0 is limited also. I thought RAID 0 split informationbetween the two drives, essentially making copies on each drive, but it doesn't stack the drives capacity. I guess what I mean is if you had 2 240 GB drives it would split info between the two drives, but you would only really have 240GB of capacity. If I am wrong then maybe RAID 0 is what I'm looking for, and I need to do more and better homework.

ok I feel silly...I think you're exactly right. I am looking to do RAID 0. RAID 1 is what I was thinking RAID 0 was.

Is it difficult to do this? If I was to buy a second 240GB ssd is it a simple process to add it and increase my capacity. or will I have to re-install windows?

Its not a hard process to RAID 0, but you will have to re-install windows. Just backup your data elsewhere and RAID 0 afterwards.

To do this, just go into BIOS and look for the STORAGE settings. Look for where it says something like "Storage Type: IDE" and change it to RAID. Once you change storage to RAID, save and exit BIOS. You should then see a message to press CTRL + I (uppercase i) and that is where you choose both your drives and select Raid 0 1 2 3 etc (Raid 0 for you). Give it a name and then hard drives "merge" as if it was 1.

For further details, read your motherboard's manual. I, too, have a ROG motherboard and I found it really easy to create the RAID setup.

If you run SSDs in Raid, you loose Trim redface.gif

"Trim" is a command that Windows 7 sends to the SSD to tell it to delete files that you have deleted!
On a HDD.When you delete a file, the OS just marks it deleted! Then data is just written over it!
But with a SSD, the data has to be deleted first. Before that part of the drive can have data written to it again! So the "trim" command!

Without Trim, once all the blocks on the SSD have been written to once. Any more writes would be slower because the drive would have to delete then write from now on!
But with "Trim" the blocks would already be clean smile.gif

RAID 0 = 240GB + 240GB = 480GB Total (dual speed but data is not safe when 1 crashes)

But if you only have 1 anyway and it crashes, you also loose everything so ... tongue.gif

RAID 1 = 240GB and 240 GB = 240 GB Total (exact copy so data is "safe" but no performance gain)

RAID 0+1 (or RAID 10) = 4 drives to mix two above together: 2x for dual speed AND 2 that makes backup.

RAID 5 is also something "like" RAID 0+1 but it uses 1 drive for storing "the RAID info"...

More or less... wink.gif

So if I were you, use RAID 0 (speeeeeed) for OS and install programs etc and other for DATA

anyone know if we will ever get trim supported on raid 0 with corsair force 3 drives?

TRIM... or Garbage Collection (or something like that. 2 options at least...)

I know that Intel are looking to release RAID 0 Trim support fairly soon for Intel Chipsets.
