| 141041 | 2003-05-03 14:04:00 | I have two harddrives (1 * 5400rpm and 1 *7200rpm) and a cd writer. If I put the 2 harddrives on the same IDE will the 5400 slow down the 7200. Should I put the 5400 as master with the CD writer on the secondary IDE. What is the best config for this. | Berryb (654) | ||
| 141042 | 2003-05-03 14:19:00 | It would be really nice to have a little bit more information as it's rather hard to tell what would be the best way to set it up. As it all depends on how they're going to be used. Running the two harddrives on the same cable shouldn't slow them down though. |

| 141043 | 2003-05-03 14:27:00 | Hi, Just because one drive spins slower than the other doesn't mean it'll slow down the faster one - data transfer should still go at about the same speed - usually the first IDE channel is using an 80pin IDE cable, which will handle faster data transfer speeds than the 40pin that is probably connected to the secondary IDE channel. Putting either HDD on the channel with a CD Rom/burner could possibly slow down the Hard drive, but the two hard drives together should run fine (I'm running a 7200 and a 4500 together on the same channel and it's not affecting performance at all. HTH Mike. |

| 141044 | 2003-05-04 00:22:00 | OK JM here goes your info. the RPM's on a drive, help with accessing the information, soo quicker access time for both sequential and random data finding. then there is the IDE speed, usually recorded in ATA or UDMA format. (they are practically the same) Now if you have 2 drives (doesn matter wether they are optical or platterzs) and those two drives are on the same 80 core cable. THe drives when been accessed independently will run at there optimal speed, for a hard-drive its usuall ATA100. For a CD-rom its usually ATA33. So there is no performance loss. However if you want to send info from the cd-rom to the hard drive then the info is only going to be sent at ATA33 as thats the maximum of the cd-rom. So in that situation you go as fast as the slowest drive. This would occur even if the drives weren't on the same channel as well because the bottleneck of ATA33 still exists. Now there is descrepancies because i believe an ide cable can only send 1 lot of information to 1 drive at a time, so if your accessing 2 drives on the same channel performance could drop further. But this maybe someone else could clear up |

| 141045 | 2003-05-04 00:37:00 | If you have a 5400 & 7200 rpm hdd's on the same ide cable, will it be better to have the OS on the faster drive (7200rpm) ?:| 7200 = Primary master, 5400 = Primary slave ?:| |

| 141046 | 2003-05-04 01:16:00 | put the OS on the fastest drive. you may want to test the drives to see which one is the fastest. a new 5400rpm drive can be faster than on old 7200rpm drive. the 7200rpm drive will have the fastest seek speed but may not have the quickest read/write speed. HDtach is a good hardrive tester. |

| 141047 | 2003-05-04 07:50:00 | Cheers for that roofus. I know most of that already though :D What I was referring to is that if you're going to be doing CD writing from one harddrive to the CDRW. You generally want these to be on different channels. So you would have the layout slighly different as to if you hardly ever burnt CDs in that manner. |

| 141048 | 2003-05-04 09:56:00 | When given the chance always have drives on different channels. Even if you are only a light user. In a pinch stick the optical drive on the same one as your hard drive. its really not going to make that much of a difference | roofus (483) | ||
| 141049 | 2003-05-04 11:33:00 | Thanks for the help. The OS is on the 7200 (Ultra ATA/100) with the 5400 (Ultra ATA/66) as a backup drive only. The CD writer used mainly for CD's with some writing now and again. Both drives are running in UDMA. The 7200 is a new drive and both channels are using an 80 pin cable. I will put the 7200 on as master on the primary and the other harddrive and cd writer as master slave respectively. How does this sound? Speed difference I suspect to be minimal in any config but thought it was worth the ask as every bit of speed helps. Cheers |

How does this sound? general rule of thumb is to keep cd drives and hard drives on seperate ide's. with most pc's it really dosn't matter if you mix hd and cd but some pc's (mainly older ones) can suffer slowdowns and other incompatibilties. |
