Taking above exceptions I consider any standard raid controller
(including SCSI ones in typical dell/hp/ibm servers) to be a worse
solution than what I described. That is based on data from real ibm
servers (2005 models ) with raid5 and SCSI 10k drives (70MB/s) i
checked last summer. I consider addon cards for ide/sata (3ware, Sil,
etc) a totally wrong solution (vendor-locking, lower performance,
single point of failure, drivers problems, more maintenance needed,
config in bios often needed).

Now this is the information that has kept me reading this thread, thank
you. I do have a few questions though,
1. How is vendor-locking used here?
2. for scsi and sata, what JBOD controlers did you use?
3. what's wrong with 3ware? I heard they're the best out of the bunch
for the right mix of performance, reliability, and price. By that I mean
without going up to the next step in cards that cost several $1000's a pop.
I'm currently looking at doing another system for storage, probably
starting with three 400 or 500GB SATA HDs, and adding more making the
whole thing a raid5 for my house but haven't found the right solution. I
plan on burning all of my DVDs to it so I can use a mix of mythtv and
probably some other program to be able to choose a DVD and play it in
multiple rooms of the house at any given time.
Of course I also plan to store some other data that i need to have be
able to stand at least one disk failure. I was thinking of getting two
seperate WD Raptor 10k RPM 74G HDs in a raid1 for the important data and
main system files.
My price budget on the server as a whole, including finding a 3U
rackmount is $2500 and I don't have any equipment to start off with, any
suggestions for how to do that right with that budget?
