EDIT Sorry for the accidental mislead guy's. Was just flabbergasted by the rigs enormity / awesomeness. Didn't think that someone would think that I was leet like you guys.

In future I'll be more clear, again sorry.

SSD's in Raid 0 = FAIL

Hmm, Oh brother...I really have to choose my words very carefully with this reply so we don't have a misunderstanding / bad exchange.

I'm not as you UK'ers say "rowing" = trying to pick a fight with you here but ...you miss the point. Its frigging humungus, awesome, expensive, overkill, etc...Lol

Maybe he has his reasons for raid 0 I don't know. I'll shoot him a text and see if he'll explain though.

Lol...I don't really know much about raid this or raid that knowledge (hope this doesnt make me a fail hehe)and only have and use 1 hard drive so I couldn't care...yet. Because I don't know. Not being snippy =(smart a**) but just because he has his hard drives in raid 0 doesn't = as you say "fail". I don't think your being fair to all his time, effort and not to mention money that he's put into it.

I guess what I'm trying to say is, if I just didn't like the color of it or the way he attached his Plexiglas to the frame, I wouldn't say he failed (I really hate this term). If I knew what difference it (raid whatever)made I would have to take into consideration all he went through and put into it and at the very least say eh, it's ok... but he should have put his hard drives in raid whatever.

Not trying to tell you how to speak or anything. Just replying as to why I thought and still think it's an awesome rig. Seriously it takes up a 1/4 of his room...Lol.

If you would care to explain what you would have put the HDD's in or what the difference is in raid whatever or provide me with a link to educate me on this matter that would be cool.

Whew...alot of work for a simple reply...no

Impressive specs there dude!

Oh and by the way have you got some special electricity deal or do you have your own reactor to power those 480s? Now we know the real source of global warming

What is 98860?? Lol

Coming back to your question concerning SSDs in a RAID configuration.

There is a thing called garbage collection on SSDs which basically helps to minimize the degredation of an SSD over time. Windows 7 also features a command called the ATA-TRIM command, which lets the operating system tell your SSD that a file was deleted and that storage space on the SSD can be rewritten. This command however is currently not abled to get "through" a RAID controller to reach the SSD itself. The ATA-TRIM command atm only works at an SSD drive stage called AHCI, which is just a the disk by itself.

With a traditional HDD (Hard Disk Drive) there is no need for massive active garbage collection so it is no problem to "loose" the ATA-TRIM command when using those in a RAID config. This is because of the way HDDs work. (Spinning platters under a magnetic writing/reading head , basically).

Setting up for example a RAID 0 on two hard drives will in theory give you double the perfomance and half the reliability. What it does is it takes both drives and writes one data strip (i.e. 128kb) to one drive and the next strip to the other. However if one drive fails all the data will be lost. The point of RAID in general is to give you a plus of reliability and/or performance over a single HDD.

SSDs are very fast by themselves, so if you put them in a RAID 0 they will be twice as fast. But there is a catch to it. Like I mentioned earlier the ATA-TRIM command will not be passed through and also the overall garbage collection will suffer, which will speed up the degredation of the drive.

This is the reason why at the moment everybody is advising not to put SSDs in a RAID config, because the speed benefit will not last long at all.

All in all,

RAID is great with traditional HDDs but at the moment terrible with SSDs.

Am i the only one not really getting this thread ?

Its not his computer he doesn't Fold + i don't find it such a great F@H machine ..

if he posts something like this he needs to cdome with a "real" EPIC rig

Al tho it did bring me on a idea...
 
I think it's just a bit of fun, Ray.
smile.gif
It's an impressive rig that would pull some serious PPD.
 
Aa yea it IS fun tho,

might add some crazy F@H rig(rack)
