RAID 5EE here we come!
Wahoo! I’m so excited
The $7,200 study at Quintiles that I was rejected from was because I had a UTI… yeah, not fun, found out a little while later when it came full swing. Anyways, been to the doctor and will be going again! I better make it on… seriously, that kind of money could be amazing for all sorts of reasons.
First off, I’ll pay someone to help me with ApplyMyWay.com already been looking at eLance for some freelancers that could help. Then I’ll put about $2,000 into an advertising budget, starting with P3 I’ll get about 45 people on the site from there to create surveys, then I’ll spend about $2.50 per post and get some people to their sites with StumbleUpon, then another $2.50 per survey to get people to the surveys. I’ll do a $120 4 week campaign on the IcanHasCheezburger.com network with their site GraphJam.com just to test that market, if it’s successful I’ll do other ICHC network sites. I don’t know all the stuff, but it’ll be about $2,000 for advertising, not paying over $1,000 to get the site running, $1,800 to pay off my credit card, $800 for RAID 5EE, and the rest goes into savings, or towards the wedding.
Alright, now, I’ve also been having some questions since my first article why I’m doing RAID 5EE instead of just regular RAID 5, what’s the difference, what’s the advantage, and what is the disadvantage? I’ll explain with 4 hard drives because that’s how I’ll be doing things, but you can do both with as little as 4 hdd’s. Raid 5 is an array where you have three hard drives running all the time: HDD 1 has information bits AB and parody, HDD 2 BC Parody, HDD 3 CA Parody, HDD 4 Storage offline no information stored. If any one of these three running hard drives crashes it is replaced by HDD 4 and the rest of the information is taken from the other HDD’s in the array to complete the array again. In a RAID 5EE array all 4 hard drives are running the whole time: HDD 1 ABC Parody Storage, HDD 2 BCD Parody Storage, HDD 3 CDA Parody Storage, HDD 4 DAB Parody Storage. Really the only difference is that instead of having a seperate “storage” drive which is what RAID 5 does the storage places is left blank on all drives and can then be shifted later. RAID 5EE is faster because you get information from 4 sources instead of 3, but it takes longer to rebuild an array if a drive fails, and it is more likely to have a second drive fail because more hard drives are on all the time. RAID 5 is safer because there is a drive that is turned off and therefore not taking any abuse, it is also faster to rebuild an array because the information does not have to be shifted around from multiple hard drives to rebuild the array it is simply dumped on the “storage” or offline drive.
I hope that helps the people who’ve asked me what RAID 5 vs. RAID 5EE will do for their computer. Personally this is going on my home computer, it is safer than running a single drive like I normally do so my information is protected, but ultimately I’m going for speed here! Not that I ever want a drive to fail, but I don’t trust RAID 0 enough to take that chance either. With a separate RAID controller that has a built in 500mhz processor for the hard drives, and 256MB of RAM I’m not too worried about the slow downs of write times for RAID 5 either, with a dual core processor, dedicated hard drive processor, 4 gigs of RAM, and 256MB dedicated to my Hard Drives… well… I can’t see that as being a bottleneck either. That is a concern of RAID 5 vs. RAID 0 but I think we’re good in this case.
