The Power of RAID.


#1

So, some crazy idiot genius got 24 SSDs and RAID-ed them. The result is a computer with a 2K transfer rate. Don’t believe me? Take a look for yourself. - http://youtu.be/eULFf6F5Ri8

I really wonder what RAID configuration they had them in. At school I got 8 standard hard drives (as standard as 15k SAS drives are) and had them in RAID0 and was getting over 500mb/s write with 16kb blocks. I feel kinda silly for not trying larger block sizes.
This was on 5+ year old hardware, surely SSDs could do better than 2gb/s (Especially across 3 RAID controllers). Although this video is from 2011, so nowadays you can probably do a lot better.

And this was also done back in early 2009 (afaik, that’s the earliest I can find this video from on youtube), back before Windows 7 introduced its better support for SSDs; not to mention the actual better progress with SSDs which yielded even better speeds.

I bet right now with current hardware you could get the same effects with about a third of the drives they used.


#4

Yeah, I’d love to get half a dozen SSDs and try it nowadays. Although I might go for RAID10 for that little bit of data security :slight_smile:


#5

Pretty sure they explain their setup at the very end of the video. It just goes by quickly.


#6

does SSD RAID’s have the same problems as HHD’s


#7

Never do this.


#8

It’s also kinda pointless to defrag RAID arrays too as they store data differently.
