Author Topic: What is Serial ATA RAID 0? (Read 181 times)

BlckMgk · « **on:** June 18, 2004, 10:36:57 AM »

I know its a configuration between HD's, but what is it exactly? Is it easy to configure with a proper motherboard? The reason I ask is because most of my dealings with HD's have been somewhat bothersome. I was shopping around and kept seeing RAID 0 etc, but they always show them paired.. i.e. 2x74GB 10,000RPM etc..

Tried a search for it, but just got more HD purchases.

Do I need 2 HD's to take advantage of RAID 0, is it a faster access rate between the HD?

Any info is appreciated.

Thanks in advance,
-BM

Raid 0 is striped data across at least 2 hard drives, no fault tolerance, doubles the risk of failure. May improve performance but I wouldn't do it.

Its what I was figuring would happen, how much of a performance increase? and How much of a stability issue?

HD's are pretty stable now-a-days, but having a no fault between 2 may get a bit hairy.

Thanks for the quick response Iron..

I couldn't advise ya on the performance issue as I have never tried it. Lemme see what I can find.

about twice as fast since the data is written across 2 paths and drives instead of one. Downfall being twice the risk of hd failure causing the loss of data. Backups are good.

I have one of the 36GB Raptors. I bought it recently when I upgraded my mb. I had planned to overclock the P4 2.8Ghz. However, even the slightest attempt to overclock results in Windows not booting. I did some research and discovered that apparently serial ata is VERY sensitive to overclocking. I tried all the settings in the bios locking the pci bus and every other thing I could find to lock the serial controller at it's designed operating speed but to no avail.

I've got two Seagate 120GB SATA drives in RAID 0 configuration. This setup screams... it's much, much faster than my old 7200rpm non-SATA, non-RAID harddrive.

Interesting. In several of their "real world" application tests the raid 0 configurations were slower than single drive. They attribute that to the increased CPU load of the raid configuration. Lends credence to my sig.

Was only two tests that single was faster than raid 0, a multimedia content creation test and windows xp boot test.
