Looking for some opinions here.I'm going to be building a new PC with three disks:2 500 GB 7200 RPM SATA drives1 150 GB 10000 RPM SATA drive.I'm going to use 1 of the 500 GB drives as a backup disk, where I'll write all my OS/Apps/Data Backups.The question I have is, should I use the 150 GB disk for my FS9/FSX installation(s), or should I put the OS on it instead? My intuition is that I'll get the best performance by putting the Flightsim apps on it since there are all the texture files and such that will benefit from the fast read rate, but want to be sure I'm not shooting myself in the foot by having my OS (and swap file) on a slower disk.

Hi Tim,IMHO, keep the OS and all other things not related to FS spread over the 500s. And put FS on your Raptor, atleast that how i have mine setup too. FS9 and FSX each on their own dedicated Raptor.

Hi guys, sorry for adding to confusion :-) here it's a 150GB plus 74GB Raptor in each box. Pagefile is on the 74GB and the rest is on the 150 drive - C - OS, FSX, etc. The 74 is split 50/50 (D-E), the second bit for drivers, installers and primary backups. External drive(s) for large backups. At a later stage, I'll put more temporary files on D. In these kind of situations, I always recommend reading up the OS' help section and what it says about the pagefile (winXP that is, haven't checked Vista yet). It pretty amusing. :-) Para-para-paraphrased :-) The pagefile should be in there somewhere, but not there where the other thing is. However, also not on a further thing but on the fastest other thing where the first thing doesn't or shouldn't reside. Well, something like that. :-) With other words, it probably doesn't make much of a difference as long as you have fast drives and your app is separated from the pagefile. Multiple drives will help not having too many 'collisions of interests'. Hope this adds to confusion! :-) Kind regards Jaap

>2 500 GB 7200 RPM SATA drives>1 150 GB 10000 RPM SATA drive.If load performance in MSFS is a primary goal,First 500 GB Drive:Primary OSDesktop ApplicationsEtc. etc. etc. Second 500 GB Drive:Pagefile (static size betweeen 1024-4092)Backup Data150 GB Raptor Drive:MSFS and assorted items found in the MSFS directory.I'd put the page file on the other 500G and not the 150 simply because having it on a different physical disk than the OS and your primary entertainment title is all that's needed. Your Raptor can be truly dedicated just to simulation.It truly is a personal decision - of the above listed thoughts, I haven't found fault in any of them. Just try to keep the OS/Apps on a physically separate drive than MSFS, and you'll gain the benefits in load times. -GG
