View source for Comparison of memory cards

{{Short description|none}} <!-- This short description is INTENTIONALLY "none" - please see WP:SDNONE before you consider changing it! -->
This table provides summary of comparison of various [[flash memory|flash]] [[memory card]]s, {{as of|2025|lc=on}}. Of memory cards (i.e. intended as such, to use e.g. internally), SD cards allow for largest capacity by far (with [[SDUC]] variant up to 4&nbsp;TB max. currently available, and the spec allocs up to 128&nbsp;max.), though the much bulkier [[CFexpress]] cards can also match the capacity. The relatively large (external) [[USB flash drive]]s allow for more capacity, and are available with 8&nbsp;TB.

| Packages the flash memory, currently soldered in shipping smartphones, into a removable card form factor.  Uses the SCSI command set including queuing. The electrical interface makes use of [[differential signaling]], which enables high bus speeds and robustness under noisy conditions and reduced pin count (compared to parallel bus alternatives such as [[UHS-I]]).

== Physical details ==
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.

== Compatibility ==
[[File:MiNe-KissX 100-7096R (705470547).jpg|thumb|Chain of adapters:<br />microSD→miniSD→SD→CF]]
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''' ('''D'''irectly compatible) – A card may be used in such a slot directly, without any adapters. Best possible compatibility.
* '''M''' (requires a '''M'''echanical 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 '''E'''lectro-'''M'''echanical 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 '''E'''lectronic 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 e'''X'''ternal 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 [[card reader]]) that holds a real card. Such adapter is the least comfortable to use.
* '''XM''' (requires an e'''X'''ternal electro-mechanical adapter) – Technically the same as '''EM''', 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 [[card reader]]) that holds a real card. Such adapter is the least comfortable to use.
* ''Empty cell'' – Card cannot be used in such slot, no single adapter is known to exist. Sometimes a chain of adapters can help (for example, miniSD→CF as miniSD→SD→CF).

The physical adapter is in fact purely ''electromechanical'', although the xD and SD protocols are ''completely incompatible''.  This demonstrates that the cameras themselves must understand the SD protocol, and thus the adapter is more properly termed an electronic adapter, with the electronic logic contained in the camera rather than the physical accessory.</ref>
