Raid 0 Ssd intel 520 240gb

Should I setup two Ssd intel 520 240gb in raid 0 mode in order to extract maximum performance?

 

[f1andy83]

I just ordered another, so now I have two. Trying to figure out if I run them as 480gb or 240gb. What's the best option? Will the speed increase be worth losing 240gb?

Mirroring will offer little to no performance advantage. Striping will boost performance but if one drive fails all data in the array is lost.

And the raid will not increase response times or 4kb read times, which is what an OS depends on most of the time. You will also lose the trim function of the OS. There is really little advantage to the raid of SSDs unless you are transferring 10GB files all day.

 

[f1andy83]

What's your suggestion to get 480gb without losing performance? I will also be running virtual xp.

Also I hear that the intel would accept trim regardless of the raid mode. Is this true? Can anyone confirm?

Is the raid from this motherboard good enough or should I get a raid card ? ASUS SABERTOOTH Z77 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

Use one for the OS and most used programs and the other for user data.

if that's true, I've never heard it. I'm not saying it isn't true, but is news to me. I would get confirmation of that, but you are still in a situation if either drive fails, you lose everything.

I don't think so. Not worth taking the risk of losing all of the data in the event that one of your hard drives fails. The biggest advantage to an SSD is extremely low access time. You don't really need 500MB/sec performance unless you want to fill the drive completely in just a few minutes.

If it was me, I'd probably return the second drive, or use it in a separate system. RAID on a desktop was all myth and hype...and thankfully has died out. Using it with SSDs can actually negate some of their advantages.

 

[pparks1]

I don't think RAID 0 on a desktop is a 'myth'. However, it has to be used in a various specific method in order to get the benefits out of it.

For example, lets say you do hardcore video editing. If you are copying a 20GB file from D:\folder1 to D:\folder2, and D:\ is a RAID 0 array, you will get a significant gain in performance during that file copy. If you were to do this type of I/O operation all day long, having a RAID 0 array helping you out would be immensely valuable.

If on the other hand, you build a RAID 0 array simply to have an "overall" faster system, which benchmarked better, or provided a faster gaming rig experience....chances are likely that the risk of data loss from drive failure was not worth the actual performance gains experienced.

 

[DeaconFrost]

The reason I refer to it as a myth is because the vast majority of people who try to use it or actually do use it, are doing it for the wrong reasons, chasing after wild performance gains that don't exist, as you described. Call me jaded on the subject, but I still recall people arguing intensively on other performance computing forums about how their frame rates in games would go way up when using two 36 GB Raptors in RAID0. I still cringe when I read the word RAID0.

Color me jaded too. I don't know if its any more reliable these days but years ago when I ventured into RAID you didn't need a drive failure to muck things up. One or two windows hiccups or a power bump and you had the pleasure or rebuilding your array again. =(

@Deacon: Exactly, they are using it for the wrong reasons. Just because a benchmark goes up, doesn't mean performance is going to increase based on what you do with the computer.
