There is no win98 limit. FAT32 is "limited" to 2TB and standard IDE is limited to 128GB/drive, you can have RAID partitions with IDE larger than that. If you get a Maxtor ATA133 controller card the IDE limit is pushed into the petabytes I think. I don't think SCSI has any limitation on size except what the filesystem can handle. WD makes a 7200RPM 120GB, that was recently going for as low as $150 after $100 mail in rebate. Maxtor makes a 5400RPM 160GB and Seagate has had a 7200RPM 180GB SCSI drive for over a year.
