Back in January when Toshiba announced their 4GB 0.85-inch microdrive, they indicated that shipments would start in later 2005. Well, later is almost here as Toshiba putting the 4GB (basically a double platter 2GB drive) into production in April. They expect initial volumes to be between 20,000 and 30,000.
Both 2GB and 4GB models spin at 3600 rpm and weigh less than 10 grams. They are targeted to mobile phones, PDAs and compact MP3 players.
