I currently have an IBM 75GXP 46.1GB, an IBM 34GXP 20.5GB, an IBM 9ES 4.5GB Ultra Wide SCSI, and finally a Maxtor Diamond Max Plus 40 20.4GB. I have about 18GB worth of data, MP3s, downloads, OS, games(these things take up massive space), and etc... With prices these days, it's getting easier to afford the larger drives. I guess you can never have enough space.
