Re: [vox-tech] NAS/Printer Server/Web Server?



Quoting Alex Mandel (tech_dev@wildintellect.com):

The latter.  

With a Sheevaplug, NSLU2, or similar (not to mention more-conventional
hardware), doing Linux md RAID1, assuming one can make sure the
bootloader works properly from either drive, I consider that an optimal
storage redundancy solution.  Remirroring after a drive failure does
indeed bog down the host a bit, but tolerably, whereas md RAID5
restriping after drive failure exacts a pretty awful performance hit.

(And with 2 TB drives as cheap as they are, 50% RAID storage overhead
seems absolutely fine to me.)

In that usage scenario, the expense of serious hardware RAID seems
absurd given that very little benefit.
