Hi all,

I've currently got a short-stroked Seagate Barracuda 1TB HDD that does around 187MB/s transfer speed (average 145MB/s) according to HDTune Pro. My motherboard has an extra RAID controller built in, which I've not used (MSI K9A2 Platinum V1) and has 6 Sata II ports.

I was wondering what the results would be like if I got an exact duplicate of the drive and set up a RAID 0 array - would it be twice as fast, or more like 50% faster? I've decided against getting an SSD for the OS and programs, so it'd be nice to fully saturate the Sata II interface (300MB/s, I think).

I understand that this won't help with access time or random seek times, but the attraction is that load times for games would be substantially reduced.

Any input would be much appreciated!

Thanks,

Ben

I suspect you will be disappointed. I think you will load in 90% of your original time.
The fast transfer speeds shown by synthetic benchmarks may not apply to the code used to load levels.

Revisit the SSD. Once you use one, you will never go back.
120gb will hold the os and half a dozen games.

yes the raid 0 will be almost twice as fast as the single drive in sequential reads/writes. You will probably add at least a minute to the boot time as the raid bios loads and then initializes the raid.
