Claims
- 1. A method of striping data onto a plurality of disk drives forming a volume, comprising the steps of:segmenting the volume into equally sized subsets of disk drives; dividing a data stream into data words; grouping said data words into groups of data words; striping a first group of data words across a first subset of disk drives, where each data word is sequentially striped across a respective disk drive of said subset; and striping additional groups of data words respectively across additional subsets of said disk drives, where each data word in each additional group is sequentially striped across a respective disk drive of each subset.
- 2. The method of claim 1, wherein said grouping step further comprises:dividing each group of data words into subsets of data words; computing parity information for each subset of data words; and storing said parity information for each subset of data words across each subset of disk drives.
- 3. The method of claim 2 wherein said parity information is computed by performing a bit-by-bit exclusive OR on each said subset of data words.
- 4. The method of claim 1, wherein said data stream is a video stream.
- 5. The method of claim 1, further comprising providing said data stream from a mass storage device.
- 6. The method of claim 1, wherein each data word sequentially striped across a respective disk drive of the first subset is stored simultaneously with each data word sequentially striped across a respective disk drive of each additional subset.
- 7. The method of claim 1, wherein said striping steps comprise striping said group of data words in accordance with a standard RAID process.
- 8. The method of claim 7, wherein said standard RAID process is a RAID-5 process.
