R600 Posted September 19, 2003 Share Posted September 19, 2003 Hi, I'm thinking of getting a second HD in which I hope to set up a raid configuration. I just want to ask everyone - what is the best raid setting if I wanted it for performance? I'm a bit confused with the (0, 1, 0+1, JBOD etc) settings for raid.Oh, I think I'll leave the 'backup' configuration out because I don't really need it.Any ideas?

midnight.commander Posted September 19, 2003 Share Posted September 19, 2003 Raid Level 0 = PERFORMANCE, you need a minimum of 2 drivesRaid Level 1 = BACKUP (mirroring), you also need a min of 2 drivesRaid Level 0,1 = is a combination of the above, you need 4 drivesThere is plenty of other raid-levels, but the one for you would be "Level 0".One more thing you will have to think about is whether you make a hardware raid or a software raid.Hardware Raid: Uses a raid controller (some mainboards have one built in e.g. ASUS P4PE or P4C800, or you get a PCI-card). This is the expensive method, but it has a better performance.Software Raid: You can use Windows' integrated software raid functions. Windows XP Pro supports Raid 0. Other raid levels are only supported on server editions. It the inexpensive method (no cost, exept a hdd), but it also shows lack of performance in comparison to a hardware based raid.Raid Info Link to comment Share on other sites More sharing options...
midnight.commander Posted September 19, 2003 Share Posted September 19, 2003 One more thing:MY suggestion is to forget about the raid!I asume you intend to buy a new hdd. So instead of getting expensive raid equiment or risking a no-performance-enhancing software raid think about getting a faster hdde.g. Western Digital 360GD Raptor 10,000 rpm 30GBIt is an expensive drive with low storage capacity (36GB) but it will boost performance!!!

ggtyh Posted September 19, 2003 Share Posted September 19, 2003 Another hint:You should use to identical drives, otherwise, the drives will auto-adjust to match the size of the smallest, so if you have a 20 GB in a stripping array along with a 40 GB, you'll have 40 GB available. The remaining 20 GB of the 40 GB drive will be lost... (if you want to recover to 20 GB, you'll have to use 2 40 GB drives or unmount your array) Link to comment Share on other sites More sharing options...
R600 Posted September 19, 2003 Author Share Posted September 19, 2003 Can anyone tell me what's the difference between setting 0 and JBOD?Still unsure about going for raid or as mightnight.commander suggested - the raptor 36GB HD Link to comment Share on other sites More sharing options...
midnight.commander Posted September 19, 2003 Share Posted September 19, 2003 JBOD = Just a Bunch Of Disks, several drives operating independently.RAID 0 implements a striped disk array, the data is broken down into blocks and each block is written to a separate disk drive Link to comment Share on other sites More sharing options...
