I've built Raid0 arrays with 2 HDs in the past, they were FAST. And now HDs are so cheap I can think about a triple or quadruple array. But at what point I saturate the bus bandwidth so much that it becomes pointless to add another HD?
Or is there a physical barrier where the PC case starts to flex from the sheer torque of the HDs spinning? |

Faster than mine, that's for sure  :

This is from an old Raid 0 (4 years old) I put on my wife's PC. It was made with a pair of barracudas using the old SATA/150 interface. It's old and yet is still faster than my neighbor's new 'gaming pc':

My backup system is flawless (or close to). I had a lot of data loss issues in the past because:
1) My wife downloads and plays every single email attachment received.
2) My son downloads/installs lots of free games of the internet.
3) My Baby daughter loves to bounce PCs repeatedly, to observe its lights.
To solve the issue, I setup a home NAS out of an old PC that I was going to throw away. It had an 80gb drive where I installed the OS, then I added 2 x 500GB SATAs for a 1Tb array. On some of my home's PCs I mapped the "my documents" folder to the NAS. For others (since my LAN is still slow at 100Mbps) I placed a Perl script on the NAS that runs daily (crontab) and mounts/backups/dismounts the PCs "my documents" folders.
I'm still vulnerable if a PC gets infected with a pretty nasty virus and goes beserk deleting stuff. It will also delete the stuff on the NAS. My plan for that is to get another SATA, a 1 terra one, and mount it on the NAS but locally (no PC will access it through the LAN). Then I can make another Perl script to backup the NAS main array into the NAS backup HD. Call me paranoid, but I'm even thinking about repositioning the NAS rig to the attic. That way, if somebody brakes in and steals the PCs I will still get to keep my children pics and videos which are not replaceable and have an infinite sentimental value.
That said, for my new rig build I wan't nothing else than sheer speeeeed. I'm not worried about disk failures, I want it to be FAST (within budget of course). Instead of getting a fast disk of around $150 USD, I prefer to get 4 or 5 cheapo disks @ $35 USD ea and make a killer raid 0 array.
I've never built a raid 0 bigger than 2 disks, ergo I have no idea if it keeps getting faster after that. I always have the option of testing the rig, and sell any unused disks on ebay if I find that the performance doesn't increase a lot. |
