If that M-SYSTEMS drive I mention is available in a reasonable quantity (i.e., more than 10) and for a reasonable price (i.e., less than say $200 for a 4GB size), then you would probably have most SE/30 owners on the planet after this SSD drive. Again, it's the perfect size and it has a 50-pin connector, and it comes in a SCSI-1 or SCSI-2 edition. That means it is just a drop-in replacement for your existing spinning platter drive, no adapters required.
