2 Different (but same) hard drives in RAID 0

post #1 of 3
Thread Starter 
Hi,
I'm building a new Pc and am working on buying the hard drives. I want two, and from what ive heard having 2 7200 rpm's in RAID is better than 1 10000 and another for data. However, my budged is limited and i want to make use of a circuit city gift card. I found two western digital hard drives one at newegg and one at circuit city, sata 3.0 and 16 mb cache, with 320 GB of data. however, they have 2 different model numbers. will this be a problem for RAID?

Model numbers make no difference. RAID setups are highly adaptable. Speeds, sizes, cache, all can be mixed. Just remember that the weakest link in the system will be the benchmark for how the system performs. You can put a 60GB and an 80GB in RAID-1 and still have security. The array will just be seen as a 60GB array, as that is the smallest disk.

I don't entirely understand how you want to configure your system, but from my RAID experience (2 250GB WD2500AAKS RAID-0), one 10.000RPM drive for the OS and one 250GB drive gave better overall performance than the RAID-0 system with the OS on one partition and general data on another. I think you are planning on the latter. I needed cash, so I sold the 10kRPM Raptor, took the other two disks out of RAID-0, and now have the OS (Tri-boot Debian, XP, Vista) on one of the 2500AAKS drives and general storage on the other. Really, the noticeable performance drop was not too much other than boot time and loading some of my bigger programs and media.
