The following chart gives details on availability of adapters to put a given card (horizontal) in a given slot or device (vertical). This table does not take into account protocol issues in communicating with the device.
Following labels are used:
* + (native) – A slot is native for such card.
* D (Directly compatible) – A card may be used in such a slot directly, without any adapters. Best possible compatibility.
* M (requires a Mechanical adapter) – Such adapter is only a physical enclosure to fit one card sized into another; all electrical pins are exactly the same.
* EM (requires an Electro-Mechanical adapter) – Such adapter features both physical enclosure and pins re-routing as terminals are sufficiently different. No powered elements in such adapter exists, thus they're very cheap and easy to manufacture and may be supplied as a bonus for every such card.
* E (requires an Electronic adapter enclosure) – These adapters must have components—potentially requiring external power—that transform signals, as well as physical enclosure and pin routing.
* X (requires an eXternal adapter) – Technically the same as E, but such adapter usually consists of 2 parts: a pseudo-card with pin routing and physical enclosure size that perfectly match the target slot and a break-out box (a

Note that a memory card's dimensions are determined while holding the card with contact pins upwards. The length of cards is often greater than their width. Most cards show a directional arrow to aid insertion; such an arrow should be upward.Speed comparison
