| 867570 | 2010-03-17 03:22:00 | Beware RAID is not data backup: en.wikipedia.org Indeed - I'm actually starting to think in a home environment, it's pointless. I've never liked RAID 0, and the speed gains were always debatable unless you were doing a crapload of I/O's; if read/write speed is an issue, get a Velociraptor or better yet a TRIM-capable SSD. Even RAID 1 is pretty pointless given the massive size and reliability of modern HDD's - doing a weekly full image of your system drive, + n incrementals a day wouldn't fill modern drive's that quickly. External backups are more for theft/fire/long-term backup etc than for full data recovery IMO. |

| 867571 | 2010-03-17 03:41:00 | My Drive layout is as follows; 160 GB (10,000rpm) for OS/Progs/Working data USB 4 GB for Windows Caching USB 16 GB for Essential Data (must not lose) USB 160 GB for Important Data + copy of Essential Data USB 1 TB for all remaining data + copy of importanta data and 2nd copy of essential data I am planning on getting a 100+ GB SSD later and I will move my OS/Progs onto that and use the 160 GB for working data. |

For sure Sol, but mirroring only protects you from hardware failure; data corruption/accidental deletions etc occur on both spindles at the same time, so it's no help. And I think corruption/deletion is more likely in a home environment, especially given how reliable modern drives are. Would always use mirrors in a server though, usually with hotspares - but that's for systems that require 4-nines uptime. |

Yes, all true, however, if you have data corruption or drive failure you can still continue...backup is an entirely difference matter. I have a NAS device attached to the network for that, however, i'd be pissed if I had to rebuild due to drive failure, its just a pain in the backside... |

| 867575 | 2010-03-18 00:50:00 | I'd create two partitions on one of the 650 Gig drives and/or leave some unallocated space in case I want to dual boot etc. Install the O/S and programs on the first partition and put data on the second. Clone the first physical drive to the other physical drive. |

| 867576 | 2010-03-18 09:43:00 | The Raid installation on the OS and Data drivers is solely for protection against drive failure. Other systems will be installed for data protection. I will set up incremental backups etc as soon as I get it all going. I'm still working on my old machine while I set this one up with all my programs etc. Each drive will be in 6 partitions as I find that helps me to keep things in order, for example one will be dedicated to images and another to video etc. My External USB Backup drive is in 7 partitions. each of 50GB.
