Raidion is a trademark of Micropolis.
In 1991, Micropolis Corporation decided to establish a sub-brand for its line of RAID-capable modular storage enclosures. The trademark Raidion® was created and subsequently registered around the globe. The flagship products of the Raidion line were the stackable disk arrays codenamed "Gandiva", which sold as Micropolis Raidion LT and Raidion LS. You can get support information for some products from this line in the Support > Storage Enclosures site area.

When Micropolis Corporation began restructuring in the late 1990s, the Raidion assets were first transferred to the renamed company StreamLogic and then sold off to a newly formed external company, Raidion Systems in Minnesota. Raidion Systems in turn was a subdivision of Peripheral Technology Group (PTGS), also operating out of Minnesota. Raidion Systems continued to sell Micropolis Gandiva systems and added a few own updated products. Around years 2006/2007, PTGS and Raidion Systems ceased operation.

Today, Raidion™ is again a trademark of Micropolis. The former web domain of Raidion Systems,, has since been acquired and redirects here, to this article. At this point, it is undecided if Micropolis will again actively market Raidion™ as a consumer facing brand.
