Hi all, Currently i am running a small server on a 5400rpm disk with only 8mb of buffer cache, but i was wondering how much of a performance gain it will be if i would place it to a 7200rpm disk with 32mb buffer cache? Anyone could tell me wat one would be better and how much performance gain i could expect and why? I am an IT graduate and usually hardware was my kind of thing, but after 2 years on mac i dont have to worry about upgrading my hardware every 6 months to stay on track with performance )haters gone hate), and i didnt know that much abouth the RPM and Buffer cache about HDDs anyways, so any help is much apriciated. The thing is, i run the server on the 5400rpm disk now whitch is the boot disk for UBUNTU so its formatted for linux, but my 7200rpm disk are from a previous server with lots of data i cant store somewhere els to format my disks to a linux format, SO these 7200rpm disk are still NTFS who i have loaded with a smb protocol on UBUNTU so i can use them and share them, will placing my MC server on a 7200rpm disk whitch are not linux formated, and run the mc server under ubuntu of one of these disk not compramize the performance? specs: ubuntu 10.04 (yup) c2d e6250 @ 2,66ghz 4gb ddr2 667mhz 5400rpm hdd, 8mb buffer, linux format (vs 7200rpm, 32mb buffer, ntfs!) any information would be apriciated! thanks.
