z0mbi3 Posted January 3, 2006 Author Share Posted January 3, 2006 No no No, not I got thme installed... but I wanna COMBIND the two so it will be 120 GB ON ONE Drive or should I say Local Disk.... is there a way I can COMBIND the 2 Drives?

sven Posted January 3, 2006 Share Posted January 3, 2006 you would have to raid them together. i have no idea how that is done becuase i havent done it before myself. im sure someone out there knows how on a desktop machine. Link to comment Share on other sites More sharing options...
KamiQuazi Posted January 3, 2006 Share Posted January 3, 2006 you wouldn't get a 120gb, u will get the double of the smaller drive... you will only get 80gb if u RAID them together... Link to comment Share on other sites More sharing options...
ripken204 Posted January 3, 2006 Share Posted January 3, 2006 do not raid those! waste of space and may not even work. just follow the guide that jcarle posted. does it really matter that you will have 2 drives? i have my 1 hard drive partitioned into 4.

gamehead200 Posted January 3, 2006 Share Posted January 3, 2006 you wouldn't get a 120gb, u will get the double of the smaller drive... you will only get 80gb if u RAID them together...Doesn't RAID 5 combine the disk space of all drives? (Not sure...) Link to comment Share on other sites More sharing options...
ripken204 Posted January 3, 2006 Share Posted January 3, 2006 raid 5 needs at least 3 drives, 2 drives are in raid 0 and the 3rd drive is a mirrorso say 2x40=80, then you will need another 80gig drive as the mirror Link to comment Share on other sites More sharing options...

jcarle Posted January 3, 2006 Share Posted January 3, 2006 RAID 5 requires a minimum of 3 physical hard drives, and[TOTAL CAPACITY] / [NUMBER OF DRIVES] = [sPACE USED FOR CHECKSUM]Which means for 3 x 80GB hard drives, the total capacity available is 160GB since 80GB is used for checksum.

ripken204 Posted January 3, 2006 Share Posted January 3, 2006 only 80gigs are used for checksum? i thought that you needed a checksum of the total disk space that u want to using(160gigs).but you may be right, we both do know that its would be 160gigs of useful space and then there is a backup disk.

nmX.Memnoch Posted January 3, 2006 Share Posted January 3, 2006 only 80gigs are used for checksum? i thought that you needed a checksum of the total disk space that u want to using(160gigs).For RAID5 yes. For RAID1 (mirroring) you need the total size for checksum. With RAID5 you lose the space of 1 drive for checksum...so if you had 6 x 160GB drives you'd lose 160GB off of the total RAID'ed space.He could do what's called JBOD (Just a Bunch Of Disks). There's no speed gain or redundancy...it'd just make the drives look like a single drive. JBOD uses each disk in succession. So basically it just writes to Disk 1 until it fills it up, then moves to Disk 2 until it's full, then Disk 3, Disk 4, etc, etc. There may be a slight increase in read speeds if the files are on different disks of a JBOD volume, but it's not going to be that noticeable.At any rate, none of these are something you can do to a drive that already has Windows installed on it without reinstalling the system. And the only way to do it from a fresh install is with a hardware RAID controller. If you want a stripe set (RAID0) then the best thing to do would be to pick up an identical 80GB drive and hardware RAID them. Software RAID will also work, but it'll use your system CPU for the calculations which could actually slow your system down. Link to comment Share on other sites More sharing options...
boggen Posted January 3, 2006 Share Posted January 3, 2006 would suggest leaving them as seprate drives and not joining them together in raid 0. small drive make it your OS driver and the new drive your apps or media or move or music drive etc... it is so much better able to format OS drive without worry of loosing all your due to being on other drive.if you setup raid 0. formating means total loose of data on both drives. if one drive fails = total loss of data on both drives. if ya go route of raid 1. 40 gigs on old drive and 40 gigs on new drive will be mirrored. if one drive fails you still have data on one of them that you can retrieve using other pc if nessary. the extra 40gig on the new drive you could use as OS drive Link to comment Share on other sites More sharing options...
