SCSI Drives Bow Out of Capacity Race

For the first time last year, it became possible to buy an ATA disk drive with more capacity than a SCSI drive. Also for the first time in 2002, the average SCSI drive sold with less capacity than an ATA drive--SCSI's 36GB to ATA's 40GB, according to David Reinsel, research manager at IDC. Today, the capacity difference between the two drive types is even more pronounced, with ATA drives shipping with two times the capacity of the highest capacity SCSI drive--for example, Maxtor's 320GB drive, as compared to Seagate's 147GB Cheetah 10K.6. Seagate recently discontinued its 182GB Barracuda 180, a 7200 RPM drive. "The Barracuda 180 was the last SCSI drive to have a capacity advantage over ATA drives," says IDC's Reinsel. Now that that's happened, drive manufacturers "don't need to keep that race up." Instead, manufacturers can now emphasize their drives' performance characteristics. Maxtor may have a 320GB drive, but it's only 5400 RPM, as opposed to the Cheetah 10K.6's 10,000 RPMs, for example. According to Seagate spokesperson ...

  • Optimize database storage

    by  Jim Booth

    In this article, author and consultant Jim Booth maintains that different database objects may each require their own type of storage to make the database operations run more smoothly. Whether you're dealing with tablespaces, indexes, redo logs or archives -- there's a right and wrong storage choice for each database component. This article explains what they are.
