Now that RAID is readily available on high-end Dells, I can regard it as a
serious option.
My sense is that RAID probably isn't a good idea, unless there's a special
need for the largest possible disk structure or to process a lot of very
large files. RAID 0 striping can increase data throughput for large files,
but is of marginal use for small files or scattered data, where seek time is
more important. RAID 0 also increases the chance of disk failure, because
there are two critical components instead of one. RAID 1 redundancy could be
useful in a disk failure, although I guess it's not of use in cases where a
software crash or corruption results in bad data being written or the
configuration being lost; you just end up with two corrupted disks instead
of one. Meanwhile, the two disks add a little more noise and a little more
heat to the PC. So on the whole, RAID strikes me as less than compelling for
the average user.
Did I get it wrong?
