I know its 0+1 Thats like my dream setup, you get the best of both worlds, speed and protection.. half the space though which sucks But I dont see the point in having 1TB of space [so much space] when you can lose it all when just one hard drive fails Can you striped 8 HDs together? (thats his setup right?)Originally posted by Vehementi
That's certainly not what I would do if I had $800 to spend on hard drives, but ok...
And agissi that's called RAID0+1, most every modern RAID controller supports it.
Then what would you do?That's certainly not what I would do if I had $800 to spend on hard drives, but ok...
Yes! Each hard drive connected to the array stores the parity information in a RAID 5. The data is then spread around to all the disks. So yeah, unlike in a RAID 0+1, you wouldn't need extra hard drives mirroring the information. You might put those extra hard drives to use elsewhere or if you had planned for this type of situation you probably would not have purchased any extra disks to begin with.Originally posted by ---agissi---
but you also get more disk space right?
Remember also, that RAID 5 only only does parity. It does not save all of the data. RAID 0+1 makes a copy of ALL of the data. Its just more protection and that really is the key to 0+1. In my experience RAID 5 isn't going to be used as much as a more fail safe RAID setup. Like LNCPapa stated, RAID 5 isn't on most consumer RAID controllers. Interestingly enough thats really where most of the use of RAID 5 would be. Many businesses wouldn't use RAID 5 simply because it doesn't do enough.Originally posted by ---agissi---
Then why would in the world, would anyone do Raid1 in the first place, when you can do Raid5?
Either just RAID0 or RAID0+1 with 4 74GB WD Raptors I have one of them now, and I can't say how incredibly awesome and how fast it is. Especially when I have a 15GB partition for extracting big files (like 1.4GB .rar's ) and encoding movies in.Originally posted by ---agissi---

Not when you have a dozen of them strapped together.Originally posted by Godataloss
From what I've read, the real world performance of raid arrays in desktops is marginally better than standard quality hd.
