I was looking for a quiet solution, thats why I was thinking about the 5400rpm, but if 7200rpm and 5400rpm are nearly the same noise, then I think I will go for a 7200rpm...
I have thought about a 10krpm, like raptor and so, but the server has to run a CS:S server and a fileserver....
The connection is a 10mbit/10mbit and 10mbit means about 1.25mb/s and even a slow harddisk, like a 7200rpm SATA can handle up to 300mb/s, which means no problem at all regarding the file server part, not even with a 5400rpm i think...
But the the game server part I think 10krpm raptor would improve performance, but I think a 7200rpm can handle it, dont you guys?
Would a single 10000rpm Raptor read/write faster than 2x7200rpm in RAID0?
Theoretically RAID0 with two disks means double read/write speed, so the RAID0 with 2x7200rpm would give me both fast read/write for the game server and alot of capacity for the file server (2x200gb or so), dont you think?
If it were only a game server then it really wouldn't matter, the server would still load the game/levels before the client, so it would be fine. But you say it will also be a file server so that may cause some issues. However, if it is only going to serve a few people at a time then it should be fine.
From my experience, modern 7200 RPM hardrives can barely be heard. Pobably the only way you would really notice the sound is if you have no fans in the computer.
I have a 74Gig Raptor and a 80Gig 7200rpm drive. I can't here either of them when my cas fans are turned up (I have a fan speed controller for the case fans). When the fans are turned down I can hear the Raptor some but I can't really hear the 7200rpm drive unless it has been sitting idle so long that it has to spin back up.
Everyone seems to be overlooking a simple point here, he's not doing anything local, serving contect will be limited to the network interface, he said 10Mb so any 5400rpm drive, prefably not set as a system drive, will server data more than fast enough. Put the OS on one and the CS data and file data on the other, or hell just the CS on the OS and the rest of the data on the other as file serving will stress the hd way more than the CS server. Just make sure you don't extra crap running on the server and you shouldn't have a problem (No AV, disk utilities, etc.)
Get the quitest drive you can find, samsungs and seagates seem to generally be quite in my experience.
The important thing with a game server is that you have a good nic and fast cpu and ram (think Intel 10/100M or S for example) Built in nics burn too many cpu cycles.
