Raid setups ***Warning, information overload***
Tell me if I have this right:
__________________________________________________
With raid 5 I can hook up between 2 and theoretically an infinite amount of drives without exceptions? With this setup I can expect the combined transfer rate performance of all the drives minus 1. So if I had my file server that I want kinda badly and I had 4 drives in it and all were put in raid 5, then I would get performance and capacity of 3, correct? And if one drive fails I am safe with data, no matter how many drives are present if two or more fail all data is lost? And this would be taking in consideration that whatever was on the failed drive has enough room to get made up on another right?
Basically I want some security, but don't want to drop loads of money into the garbage truck for no reason! I would also want the ability to make any amount of drives in it, meaning I may have 2, 3, 4, 5, etc. to set it up, any number is possible correct?
Question: can there be data loss when a drive fails? This is better for performance (with 4 drives) then raid 1+0? Also, once the raid is created, I absolutely must keep the same amount of drives present until it is deleted, it will not like me if I take add later on? How good is this for security and rebuilding data?
Compared to raid 0:
Raid 0 will only give you performance of that one last drive added to the rest correct, that is the only difference? What about the amount of drives, typically someone sees 2 in raid 0, can 3, 4, 5, 6, etc. be hooked to ONE raid 0?
General questions:
What if there aren't enough serial connectors? maybe there are 2 for 2 raid setups on the mobo or something (4 total, but they are separate), and I want to put 3 or 4 drives onto one raid, are there splitters or anything or am I stuck with whats built into the mobo/card?
I don't think the Asus mobos have raid 5, anyone know if that is true? Do cards typically have more raid options?
What are good recommendations for cards? brands, models, etc.

Mother Boards with Raid controllers. I have been running for over 3 years. There are several on the market primarily using the onboard HighPoint Controller. You can place up to (4) HD ATA/UDMA type drives on the raid controller, running mirror or parity as well as up to (4) HD on the serial connections with no raid config.
WARNING: I just suffered this for the first time. Soyo MB ran a RAID striped set with (2) HD for over 2 years. One of the HD went bad. Guess what...zero data integrety, I lost everything on the RAID striped set. I sacrificed speed for redundancy. Not a problem if you can afford to loose data that is not backed up. The good thing is with this config you can place (2) more HD on this controller as standard HD, not part of the RAID. If I were a smart man I would have used (3) HD in the striped set for redundancy and just replaced the failed HD.
There are many, many posts here about RAID configs. If you do a search you will find them.
Good Luck
RAID 5 has the best of all RAID levels, and yes, it has "full security".
okay
