To Raid κανει τι διαφορα σε ολα τα bench που εχω τρεξει(εχω 2χ74gb Raptors) κ σε real world εφαρμογες οπως πχ σε παιχνιδια,φορτωμα win κ τα σχετικα,ΑΡΚΕΙ να μην εχεις 1-2Gb RAM οπωτε τοτε η διαφορα σε ταχυτητα μικραινει αλλα παραμενει

Ααα κ καλοδουλευτος

......και το πιο βασικό που δεν είπατε ακόμα, να έχει ο κάθε δίσκος το δικό του κανάλι PATA/SATA.

[LL_NEO]

Το raid άρχισε να διαδίδεται μετά την έλευση των SATA δίσκων οι οποίο ως γνωστόν .... δε μπορούν παρα να είναι μόνοι τους στα κανάλια τους.
