Heya, I'm currently sporting the following rig: AMD A6-3500 APU ASUS F1A75-M Motherboard 2x4GB Corsair Vengeance DDR3 1600MHz 2x Seagate Barracuda 7200.9 250GB SATA2 HDD 1x Seagate Barracuda Green 2TB SATA3 HDD I use the 2TB HDD for media storage, but I have run out of space, so I have purchased an additional two identical HDDs to boost my storage to 6TB. I would like to set the drives up in either JBOD or RAID 0 (striping), but am not sure whether that would be efficient ... The 250GB drives are over 6 years old and one of them is making some really unhealthy sounding noises, so I'd like to get rid of them. At present, one of the drives are used for my OS and software, while the other is used for storing backups of software and game installers. What sort of performance issues and general problems am I likely to run into if I were to install my OS and software on one of the 2TB drives (they only run at 5900RPM). This isn't a performance oriented computer and is primarily used as a media server and HTPC. It's left on 24/7 and is scheduled to restart once a week in the middle of the night so startup and loading times aren't really an issue, so long as I don't hit buffering issues. Additionally, if I do decide to keep my OS on one of the 250GB drives, would I be able to setup a JBOD or RAID 0 array across the three 2TB drives, without losing the data on the drive I already have. Or would I have to make a backup? Thanks in advance!
