Clicky, check out the bar graph towards the bottom of Eugene's post. SR will be posting a pretty comprehensive article on RAID, hopefully soon. The graph is a selection from the results obtained for that forthcoming article.
Even running _four_ WD740GDs in RAID-0 is not enough to match the single user performance of a single WD1500ADFD. The 4x RAID-0 array manages a tie in the OfficeDriveMark, but falls short in the remaining four of SR's Desktop DriveMarks. Also observe the 4x RAID-0 array delivering _slower_ performance than 2x RAID-0 in FarCry and WoW, and only managing a gain of a few percent in the Sims 2.
You are welcome to say what you want, but the simple fact remains that no RAID setup will deliver improved desktop performance. Power users looking to increase storage performance should look to faster single drives or adding indendent spindle(s) to service additional loads.
RAID-0's shortcomings are well documented:
A) Reduced reliability
B) Increased heat/power draw/noise
C) Increased system complexity
D) Greatly complicated backup and disaster recovery
E) Substantially increased cost
However, many have tried to justify/overlook those shortcomings by simply saying "It's faster." Anyone who does this is wrong, wasting their money, and buying into hype. Nothing more.
