Not a single complaint with the thing thus far. It's been in service
since late September, and I use the array CONSTANTLY, all day long. It
holds my mail spool, GB's of media, MP3's, the lot in other words. The
one thing I did find is that Linux softRAID responds very poorly to
power loss. No data was lost; but after the second time I had to wait
2+ hours for the thing to resynchronize, I decided I'd better splurge
and get a UPS. No problems since...
Of course, if you're going to use the HighPoint for RAID, you need to
ignore the fact that its four channels can each handle a slave &
primary. Promise won't let you put on slaves, neither will 3ware to my
knowledge. I'm sure you've read/heard this elsewhere, but resist the
urge to add more than four drives to the thing. If a master drive
fails, it will almost certainly take the slave out too. That would
turn your recoverable one drive RAID-5 failure into a fatal two drive
failure, and woe to you.... 'Sides... These things are cheap enough,
if you want 5+ drives, just buy an extra controller! There's stable
Linux driver support (including multiple cards), so they're a pretty
stable budget RAID solution.
Parallel lines never meet, unless you bend one or both of them.
