Long time

So I called MS tech support and turns out my problem was fixed in other cases by reinstalling. So I did, and now I have to reinstall about 10 hours of install programs again.. luckily I burned my Warcraft III savegames so I can keep on smitin'. Excellent. I bought another hard drive the other day and I'm going to set up a RAID array, I think. I've never done it and I wonder if I'll notice any improvement in performance.
I just got back from the lab about 45 minutes ago and I'm going to leave to return in about 10. My experiments are 9 hours long today, unfortunately. My boss told me that everyone's leaving the lab next year so I'll be the most senior person in the lab (or the 'boss', as he put it). He said that everything wrong in the lab will become my fault, but it would be worth it just to get my desk space moved from out of the UV transilluminator closet.

This new graphics card rocks. I almost need my glasses to read the text at 1280x1024 resolution. Well, I'm excited but I haven't reinstalled Norton so I'd better get offline before my computer curse hits.

Mmmmm... 1280x1024.... I'm jealous, since my lappy doesn't do that...

However, my PC does... and so does muh Mac!

There are two reasons for a raid - speed and backup.

Raid 0, or striping as it is called, puts the data in interleaving stripes on two different drives. Since drives can only transfer data (typically) at 50Meg/sec sustained (if you have a good drive) Raid 0 puts the even number blocks on driveC and the odd number blocks on driveD. *this is a simplified explanation rather than the real way it works btw* So when you access the file, two drives together begin spitting data out giving 100Meg/sec. Yes, drives can go up to 133Meg/sec transfer rate, but that's a burst transfer limit and not a sustained average realworld rate. In the realworld, if you get 50Meg/sec average rate then you are doing very well. You are making two hard drives into one. Here, your danger is that the files are spread out between two discs and if either one dies, you lose everything.

Raid 1, or mirroring, puts your data on two platters at the same time. When you read, if either one has an error, that data is ignored and the good data from the unaffected drive is used. Uses two drives to give an on-the-fly backup, but no speedup. This prevents a drive failure from crippling you and you can take the time to shut down and replace the failed device.

Raid 0/1 does both, mirroring and striping. When you write data to the disc, even data goes to the even drive while a mirror goes to the Odd drive and vice versa for the odd data. Not as fast as pure Raid 0 but okay.

Raid 0 is used by people wanting very fast data pumps, like you would need during video recording.

decisions, decisions.
I decided to install striping when I got the DVDwriter, if only to speed up my ability to thwart the MPAA by copying DVDs. But after I thought about my luck, I'm considering installing striping/mirroring instead. I do have 3 HDDs now that my old computer doesn't need its drive. Although I'm unsure on the ordering of the drives, since I think the old is only a 5400rpm and is only 30Gb, while the other two are both 60Gb 7200rpm.. Or I could rebuild the old computer (assuming I didn't really fry my old mobo/cpu/dimms/agp) and network the two for kicks; I can't see what good doing that would do, though.

I'm very distraught also b/c something went wrong with saving my Warcraft savegames before I deleted my old partition and now I have to start all the way over.
