As the title says 
I've currently got a Sata150 WD Raptor 74gb
I'm upgrading the rest of the system but here I have a dilemma
A 74gb Raptor costs just over £100 still.
Would I benefit more from buying another of these, setting it to Raid 0 or will I get faster drive performance from buying two 120gb Sata300 hdd's and raid 0'ing these?
Two 120gb Sata300's (7200rpm) I can get for around £35 each
The drives will be used for the operating system only, valuable data will not be stored on them so disk resilience is not an important factor.
