I found the article I was mentioning, about a pitfall with RAID (RAID-5 specifically) due to the increasing size of our hard drives. It has to do with the probability of "unrecoverable read errors" becoming an almost certainty, thus negating the safety of RAID-5.

  Thanks, I've seen that argument before and it misses an important factor. The article assumes that a disk may not be fully read to detect the unrecoverable read error until a rebuild is initiated. Good RAID controllers will periodically sweep all the drives in the array looking for problems like this before they have a chance to bite you like this. For example, Dell PERC RAID cards will periodically read all the data on all the disks looking for these kinds of errors. When found, they will mark the sectors bad, rebuild the data from parity on the other drives and go along its merry way. If too many bad sectors are found or there are other issues from the SMART logic on the disk itself, PERC will notify you with a predicted failure notice so you can take action before a drive has even failed. Granted, if you're using software RAID or a cheap controller you may not get that protection and this guy's article does hold some water.

  Hi, Justin - You did aptly mention quality of the controller yesterday. Also, I should note this article is from 2007, and I don't know if the author ever followed up. He did write an article last summer about up-and-coming technologies he asserts are better than RAID (in which he refers to his 2007 piece) although I think the title is poorly worded. It's an interesting topic in general. http://www.zdnet.com/...

Anyone know how to program a microwave to make fajitas as good as the Two Senoritas ones? :)

The hostess said they could handle parties of 20-30, so I'll update the RSVP number now. Looking forward to seeing everyone!

I will call the restaurant in the morning to see if they can accomodate a group larger than 15, and if so I'll modify the number of RSVPs available. If you don't think you can make it please update your RSVP so I can have an accurate count when I do call.

Just a reminder that this event takes place downtown, so make sure you give yourself extra time to find parking. There's some on-street parking in front of and nearby the restaurant. The Palm Avenue Garage is free and is right around the corner, and the 2nd Street Parking Garage across from Whole Foods has free parking on the 2nd level and is about a 3 block walk from Two Senoritas.

  It is not that bad to park at Bayfront Park and walk either.

This place has great fajitas if I remember correctly from the last time I was there. The margaritas are also pretty good, if you're into that sort of thing. There's a great little bookstore next door if you need to kill some time before or after the meetup.
