7200 SATA RAID 0 vs 10000 RPM no RAID

Which is faster:
1.) 2X 160GB SATA NCQ II Drives in a RAID 0 configuration
or
2.) 1X WD Raptor 74GB 10,000 RPM single drive ??
How much faster are either of these configurations verses a WD Caviar Special Edition ATA100 - 120GB PATA drive?

Thanks.

  1. Depends on what you're doing. If you're loading a lot of small files then the raptor will be the fastest. If you're manipulating large files, then the raid array.

  2. I will most likely be working with larger files.
    Which SATA NCQII Drives do you like the most for RAID 0?

    Thanks.
  3. Since the access time is faster on the Raptor, that will be faster most of the time. If you are video editing or such, the RAID array will be faster. I was going to get 2 200 GB WD's in RAID 0, but I got a good deal on Raptors, and decided to go with 2 74GB Raptors in RAID 0. In that case, you get fast access times and fast read/write speeds due to the array. A RAID 0 array will always beat a single drive Raptor ( well unless you are using 8.4 GB drives, lol.) It depends what the drives will be used for. I use my system for video editing, so the Raptors really help. According to HD Tach, the Raptor tag team gets 112 MB read, and about 80 MB read.

  4. I bought two WD SATA 160GB Caviar drives and am running them in a RAID0, I use my rig for gaming, video editing, 3D rendering, etc... wish I would have spent a couple extra $s on the Seagates for the NCQ, not that I'm unhappy with the WD's, but just for bragging rights.
