Well, I rarely use Torrents, so I'm not very familiar about that "auto-move" function, sorry. But, unless that function moves the files and updates the "read torrent+data from..." part (which would cause severe random reads on the RAID-5 array, and that's NEVER a good idea with RAID-5, hardware or otherwise), you'll automatically stop seeding that file, so yeah, that would pretty much kill your ratio.
What you said, only difference would be that the price should be about equal for both parts... hehehe
lol I've never had issues with manual moves before. Unless on those files that were corrupted to start with (one of my server's memory sticks started missbehaving... it took me months to figure why I had to download some stuff twice, and sometimes video files had glitches...).
Granted, I don't move whole folders, only individual files (or groups of files), so that may well be the reason I have less problems... Though I'll keep that in mind.
Well, if you had both, you simply had to wait to install them again, unless you couldn't point the origin of the hardware. THAT would be a tough sell indeed, one top-of-the-line RAID controller AND 3/4/5 über-capacity (and price... lol) drives all failing at the same time... Can you say "not happening"?
Btw, one thing I've been thinking (run for the hills! lol): RAID controllers are basically dedicated CPUs and memory for the parity calculations (not even needed when reading, unless if the array is cripled). Also, it's very clear that parity calculation takes a fraction of today's CPUs computing power (see the links I posted a while back).
So, my point is, since there are usually no backup bateries on CPUs like there are on hardware RAID controllers, to keep data from being lost after a power outage, software RAID most likely calculates parity for every block written, and sends it immediately to the drive, to minimize data loss, without even considering storing it on RAM. This, of course, creates abismal performance for software RAID, when it could actually be the fastest configuration available...
So, am I too off on this? I don't think so...
Also, would it be possible to rewrite Intel or Microsoft's RAID driver to actually use system RAM as cache, before sending the data to the array? This would open up insane performance boosts on software RAID...
Cheers.
