raid ssd's

buzzlightweight · 17 Feb 2011 at 15:58

i have an intel 40 gb ssd which is getting close to its limits on space, so i am going to be buying another one and putting it into raid 0,

i have just googled how to do it and was wondering if it is just a case of configureing the bios? or do i need to do anything else?

thanks

RAID0 won't give you more space, will just make it faster. You do know that right?

Yes he will, if he buys another 40GB HDD he will have 80GB.

*facepalm*

Not if he puts them in Raid0

Yes, if he puts them in RAID 0.

RAID level 0 is striped. RAID 1 is mirrored.

A RAID 0 can be created with disks of differing sizes, but the storage space added to the array by each disk is limited to the size of the smallest disk. For example, if a 120 GB disk is striped together with a 100 GB disk, the size of the array will be 200 GB.

To actually answer your question...it depends (see below)

Don't want to teach you to suck eggs but for the sake of those who've posted incorrect statements above: Put them in RAID0 will give you double the space and a performance boost (the writes and reads are split over both drives simultaneously so in theory should both be twice as fast). But if one fails you'll loose everything.

As to whether you just configure them from the BIOS, well sometimes that'll work and sometimes it wont. It depends on the OS and the motherboard as to whether it will boot without having to add different drivers.

My old Nvidia based board didn't seem to care what arrangements you had regarding single drives and drives in raid, you set it in the bios and it would boot, even migrating installs from single drives to RAID It just worked.

However my newer X58 board has different drivers for the chipset depending on how you configure the storage controller in the BIOS (IDE/ACHI/RAID). You can't move an install from one to another without installing different drivers beforehand, or better yet doing a clean install.

i been running raid 0 for the past 10 years.

i have yet to have a failure!

i was reading this at work. ppl was wondering wtf i was laughing at....

thank you for your explanation, as to your concerns of potential data loss im covered by 4 2tb hdds, i will only use the ssd's for os and programs which i have all disc's and data backed up

i will be doing a clean install on a new Gigabyte P67A-UD7 Intel P67 Chipset (Socket 1155) DDR3 Motherboard - (Sandybridge).

LOL

On a side note, could you set up 2 drives in hardware raid 0 (like the 2 SSD's) which would then show up as 1 drive in windows and then have windows have those two (windows would see them as one) backed-up by software raid 1 onto a third drive?

Raid 10, or 0+1? I read that it needs 4 drives of equal capacity, not sure if it works on 3.

Two drives would be in Raid 0, and the other two in Raid 1 and the backups would be automatic.

Its far easier to just add a double capacity drive and run windows backup every month. Dont keep anything important on your Raid 0, just games and benchmarks are fine, windows too if its an SSD raid. Have another drive for media and documents.
