Greetings ,

I realy want to know how faster the SCSI hard drive than IDE drives , this will help me with choosing my new server .
and which is more important and can effect bowsing speed is to use 1GB RAM or to use SCSI hard drive ?

Thank you,

if it a static download site - go for RAM, if database-driven or a box will have a lot of write requests (along with read requests of course) - SCSI will help more than RAM in most cases.

p.s. assuming that you'll have backups elsewhere. 'cuz usually SCSI drives have better lifetime than IDE ones, but there are tons of exclusions lately :(

the SCSI drive is 2800 rpm faster ;) :D

what is better for you depends on what you do and how much disk-io you have

a 10k SCSI drive is about twice as fast if it comes to DB tasks or swapping

lately i heard of SATA drive what is it ???? sorry for my ignorance.And thanks for helping me.

usually a scsi controller has a dedicated processor for io, where ide uses your cpu for cycles

as for the swapping - if your system started it the drive will never help. swapping is bad for a server. period.

SATA drives are the serial version of IDE drives while PATA are parallel one.
SATA drives are a bit better than older PATA due to some queue reordering, but still SCSI ones are better yet much more expensive.

Hey Thanks Aleck.

no probs. check out 'mass storage' section on www.tomshardware.com

It's not as much how fast 10000 vs 7200rpm, it's the fact that SCSI uses an on board processor as opposed to using the CPU. IDE and SATA both use the CPU for processing, which adds to the overall CPU usage. SCSI is generally more efficient in that aspect.
