Ah. No, I am using RAID0 since this is just scratch space for
editing large uncompressed video files.
Man a 3ware for RAID0? :D
I cannot wait for port multiplexer support on libsata (or is it
libata?) in Centos 5. An elcheapo AHCI or whatever SATA controller +
Linux software raid will own 3ware cards on a price/performance basis :D
An 8-port 9550SX card is only US$500. Why on earth would I mess around
with software RAID when that card is going to make things a plug and
play proposition? It just isn't worth the hassle.
Yes, a 3ware card + large case will always be cheaper than trying add
external storage via eSATA. I forgot the environment :P
As for hassle, I guess it is only a hassle on Linux...
Disks are so cheap and high enough capacity now that I don't even
bother with RAID5 anymore. I still don't think (even if I was using
RAID5) that I would stray from the "vendor supported" ext3 filesystem.
Not when you need that fileserver to serve. I'd go with JFS. XFS is
too risky even if the code was not iffy. ext3 + 3ware RAID5 arrays is
that bad. IIRC XFS was somewhere like 4-5 times faster than ext3 and
no, i am not talking about 3ware 75xx/85xx boards. I am talking 3ware
95xx boards with onboard RAM.

If you need to serve files in an enterprise situation and you *cannot*
afford a $500 RAID card, then I think you've got more pressing issues. :)
Er...I was referring to not using ext3 on a 500USD RAID card that it
does not gell with.
