RAID 0 vs. Single Raptor

post #1 of 6
Thread Starter 
In the next month or two I am going to get a new HD setup and make the switch to Vista. Right now I have a Seagate Barracuda 320GB HD. I am thinking about setting up RAID 0 with two Barracuda 160GB HD's and using my current one to backup files every month or so. I have seen the numbers on RAID 0 and single Raptor drives, but is their a significant real world difference in performance? I use my PC for general use and lots of gaming. I want high performance without spending too much cash.

In all honesty, technically speaking in terms of Access Times and CPU Utilisation are far superior on the Raptor. But Raptors are getting a little dated and modern drives like the Barracudas are faster in terms of Average Read performance.

Access times etc on the Raptor you will not notice unless your like looking at numbers in HD Tach. For pure performance average read is what matters as that's what you'll notice when loading up your games.

When you say that Barracudas have a faster average read time than a single Raptor, are you takling about Barracudas in RAID 0 or a single drive?

A single Raptor vs a Single Barracuda is a tough one, in my findings they are almost identical in average read perfomance. RAID0 would obliterate a single Raptor. Now, in terms of price/performance the barracuda is better. You can purchase 2x Barracuda for the cost of a single Raptor.

Single one. I have a 500GB Seagate 7200.11 that gives me 91.5MB/s average read...

I get ~135MB/s average on my RAID. Unless you need the speed for apps that work with large files (video editing, CAD, ect) RAID really isnt worth it unless you want more that 1 TB of storage. I would look into a Velliraptor. They a little costly but it will give you greater performance if you need it. In most cases, with going to RAID, you will only see improvements in your HDTach benches, not real life performance increase (unless you work with video editing, CAD, ect.).
