Corsair Force Series GT or WD Black 2TB

Ok , I am going with two of the intel.

But now i have a question.
To RAID or not to RAID ?
As far as i remember RAID was used to backup certain data from a drive to another drives or something like that.
I do not understand how would RAID increase performance.
Also i heard people talking about "Controllers" that improve performance as well, i do not know what is that.

I really wouldn't bother with raid

Two most popular RAID types: RAID0 and RAID1.
RAID0 isn't a true RAID, as it doesn't help with the redundancy of the array at all - it actually makes it more volatile.
RAID0 is what yo use if you want to theoretically improve the performance of your drives. It does this by 'striping' your data. For example, this is a string of data: 101010101010101010101010. In RAID0, all the 1s would be stored on one drive (this is if you have two drives in RAID0), and all the 0s on another. Alternate bits are sent to different drives. This does however mean that if one drive goes, you lose all your data with, as I understand it, no chance of recovery.

RAID1 is a mirrored RAID, where every single bit of data is cloned onto another drive. This RAID can show benefits on read speeds, but not as much as RAID0.

I have two 120GB SSDs in RAID0, and I honestly can't say they're faster than they were non-RAIDed.

RAID0ing your drives also removes the option of TRIM, which is used to stop your SSD's performance from decreasing as much over time.

i would just get one higher capacity drive. as josh said raid 0 ssd's is a pretty bad idea. one drive will be easier to deal with as you wont have to worry about one drive failing etc.

Can you explain the event of drive failing ?
Does it happen so often ?
And when it happens , Do the drive that have failed become useless (permanent hardware fail) , or just a reboot will fix it?

Knowing it will be used for OS and frequently used applications and games.
No source or critical data will be in the SSDs.

At last the raid shall give almost 2x performance ?

As already mentioned, i've not found any performance increase by RAIDing my SSDs. Maybe that's down to the onboard RAID controller on my motherboard, but I just don't think it's worth it. Any current generation SSD is plenty fast for anyone. You click an application, and it opens straight away - what more do you really need?

No one can say how often a drive shall fail, as it's different for each drive. I haven't had any issue with mine, but there are plenty on this site alone that have. RAID0 means you have 100% more chance of needing to redownload all your stuff - not a disaster, but still an inconvenience.
It also depends on what kind of failure it had, just like any other type of storage device.

I am more concerned about a permanent failure. how often ?
Nothing to redownload , only reinstall .

 

[Josh Weston]

As long as you stick with Crucial/Samsung, not very often at all.

The best i can have is intel, with the ability to return to seller in case of failure.
Otherwise it will be international shipping , and item returning may not be as easy.

i´m using corsair, no problems whatsoever
