Subject: Re: Raid Card controller for FC System
I've used both on many occasions, but I prefer a good hardware raid
controller, I like the idea that data integrity does not rely on my
personal "expertise" or access at the time shit hits the fan, so for
example, if a disk fails I can call the data center and say unplug
disk #2 and plug in the spare disk (assuming no hot spare) thank you
boodbye, I can then head back to the beach :)
Now, I know in your case it is for home use, but hey the link I posted
you was top of the range card for only $300 and it does what it says
on the tin :)
My inquiry was due to wondering how dependable was the data integrity in
a soft RAID if my system drive craps out. I thought my data would be
safer if the RAID was less dependent on the system. I suppose any
corruption in a soft RAID after replacing a failed drive is very rare,
right? That is right, RIGHT?!?!?! *anxietyattack*
I have had the raid card internally fail in a non-obvious way and corrupt data
internal to the card, replacing it with an identical one make the errors go
away, lucky this corruptions was only on read and the underlying data appeared
to be fine.
And if the crap really hits the fan (multiple disk failures, and number of other
things), you often need to know how the enable expert mode on the raid
controller/enclosure and how to properly work you way out of it, and doing the
wrong thing can leave you with data corruption.
