I'm looking for a cheap solutions for a SATA raid and have about 1 terabytes of space.

I see this, RocketRAID 1640 - is it any good? http://www.newegg.co...N82E16816115015

Not bad for only $86! I'll get a couple of 400 gig SATA Hard Drives as well.

RocketRAID is very good hardware! This version, however, isn't actually a hardware raid. It is a software raid and thus, isn't as fast as a hardware raid. It is much cheaper and a great option though.

Well those for sure are nice hardware, but from my experience I will never (until it is a critical need) use any RAID devices.

I am curious TalkPenguin as to why you are so adamantly against raid? It would seem to me to be a useful way of building in redundancy for important systems. Is there a way that you would prefer?

RAIDs are excellent for data protection. I curious to know why you are against them as well.

if your going to get a cheap card, it's going to be more then likey pesduo raid (the raid support is done in the drive in the system and not on the card). and if you are going to go that route, i would recomend using linux software raid, and not a card, mainly because if the card dies, and you can't get a replacement, your pretty much screwed. if you use linux software raid, it's alot easier to managed, and alot more portalable

if you want pure speed, go raid 0 (striped), if you want some speed and don't much losing a bit of disk space go 1 or (0+1), personaly i always use raid 5 or 6, basicly raid 5 is the size of all the disks -1, and raid 6 is the rame, but -2, and you get most of the speed from all the disks (raid 5 is basicly striped and paridy so you get speed and backup).
raid 0 - lose a disk, ALL data gone (pure speed)
raid 1 - lose a disk, still have data (speed and backup)
raid 5 - lose a disk, still have data (lotsa speed and backup)
raid 6 - lose _2_ disks, and still have data. (a little slower then raid 5 but high level of reduancey)

hopefully that information will help a few people.

What have you got against RAID devices? I was led to believe that there weregreat, especially for data protection reasons.
