Don't be sad, I was just learning that the RAID is in-fact
software-based and all 160 gigs will be usable. The more hard-drives,
the merrier.
But back to the tech stuff. I just had a thought about videl but I
could certainly be thinking wrongly with my limited knowledge about videl.
~ "Software-RAID, by its very software nature, tends to be more
flexible than a hardware solution. The downside is that it of course
requires more CPU cycles and power to run well than a comparable
hardware system."
Does videl have an available PCI slot? If we still got the low-end
60G (and it still fits) and spent $20 on a ATA RAID controller we
could stop doing the software RAID thing and improve performance and
reduce CPU usage. It was my understanding that videl is worked very
hard in cpu/memory.
In my limited experience, i've only compared the performance benefits
of moving software->hardware using SCSI so I am uncertain about the
level of benefit of moving to true RAID via IDE. Also these RAID 0/1
controllers may be so low-end that they may not even be comparable to
today's software implication in Linux.
Of course, thats a lot of drives and videl would at least have to be a
2u or a very fancy 1u to fit them all in or have a ballsy PSU.
