In point of fact, the Microdrive is indeed a hard drive. Its form factor and interface are the same as a Compact Flash card but internally, both in form and function, it is a hard drive. (See http://www.hgst.com/hdd/micro/datasheet.htm )
At the time it was introduced by IBM, it held a considerable advantage in price and capacity over contemporary Compact Flash cards. However, nowadays a 1 GB CF card is comparable in price to a 1 GB Microdrive (about $180 for either). If one wanted to give the gift of music to an athleticly inclined grad, now's a good time to snag a $49 MXP from the e.Digital store, add a $180 1 GB flash card, and present them with a skip-proof voicenav player at a very reasonable price.
. "It is not technically a hard drive" the microdrive is an HDD...it can be configured under three different modes of operation....meeting different industry standards.
CF is an ATA standard with attachment....to allow for HDD performance....CF is meeting HDD criteria...not the order as you comment.
It's an addressing issue...
Edig is driving the bios of these different periphery through their(MOS)low level management....derived from application embedded IC technology.
Edigs ability lies at the IC level...where they have the ability to drive embedded items such as flash....and make it function as if it where CF....etc.....under its own proprietary standard. This happens at the embedded level with an RTOS having a full low level /high level complement. When utilizing flash....because of their patented data and allocation structure.....they perform.
