You guys are very brilliant -- but since this is an encyclopedia and not really a user chatboard -- would someone be so kind as to actually explain in simple terms what is the function of an ExpressCard? The only description seems to be that it's superior to a PC card -- but what does a PC card do? Is it like a jump drive? Is it to carry data? Please let the rest of us know... Thanks so much.

Over 10 years later, I had the same problem: what is it for? Couldn't find out.

Heres the problem: Need to connect a 3G PCMCIA card to my expresscard slot. Any solutions?
An anon over on WP:AFC requested this be created. As his proposed article has information that seems to be missing, I'm reduplicating it here:

Do 54 cards fit in 34 slots? What about 34 in 54? -- Abdull 08:39, 27 May 2006 (UTC)
Added this -- Profnick 01:11, 3 July 2006 (UTC)
Yes, 34 fit in 54 slots, but not the other way around. The 54 cards are simply wider, but use the same connector. 69.87.200.181 13:56, 25 November 2006 (UTC)
I'd like to see some technical explanation on why these are superior to the PC card. -- Yamla 16:12, 29 June 2006 (UTC)

The voltage claims don't make sense. These cards are said to run on lower voltages. But the USB 2.0 standard requires 5 volts. Is it available on this connector, or not? 69.87.200.181 14:00, 25 November 2006 (UTC)
It would be good to have some good external links to lists of what cards are actually available in this format, at least until it becomes more common. 69.87.200.181 14:00, 25 November 2006 (UTC)
Perhaps the Where to Buy section of the ExpressCard site fits the bill? Someone want to write up a small section for available cards or should this just go in the references? -- Pcloches 22:11, 1 December 2006 (UTC)
Unfortunately, I've been scouring the 'net looking for an ExpressCard Bluetooth datapter... simple reason? Those darn usb bluetooth dongles all stick out so far that you have to pulg and unplug em every time you store your laptop. An ExpressCard Bluetooth adapter that could just be left in the slot would really make my laptop useage a much better experience. The ExpressCard seems to be bordering on vaporware. You'd think that some company would realize that just adapting a tried-and-true bluetooth chipset to the new format would generate nice profit ... and they'd be the only player for a little while at least. ~sigh~ -- DigitalSorceress 13:54, 28 April 2007 (EDT)
UPDATE: well, I did find (hopefully NOT vaporware) a decent USB bluetooth adapter that may solve my initial complaing:: the MoGo Dapter Supposedly to be released June 2007. -- DigitalSorceress 14:02, 28 April 2007 (EDT)
I've not seen it mentioned anywhere authoritative (or indeed anywhere else at all), so it can't be added into the article - but there are apparently no ExpressCards providing SCSI interfaces. Adaptec do/did a nice line in PCMCIA SCSI cards, but I've been unable to find an ExpressCard equivalent. This is not good, as I have a pile of external SCSI kit that I like to be able to connect my laptop to. Is there a fundamental technical limitation preventing offering SCSI interfaces, or is it lack of market size? I have a SCSI filmscanner, a SCSI MO drive and a SCSI coffeepot (actually, I'm joking on the last one) that I'd like to be able to connect. 85.158.137.195 ( talk) 08:38, 1 October 2008 (UTC)
The attached diagram
shows that the CardBus card connected through a CardBus controller, while the USB option of the ExpressCard connects directly to the system bus, which is a bit misleading.
Is there even really a CardBus controller? Isn't it just an extension of the PCI bus (or ISA bus on the older PCMCIA cards)?
-- Pcloches 22:11, 1 December 2006 (UTC)
From the article itself: "whereas CardBus utilizes an interface controller that only interfaces with PCI". -- Indrek 21:17, 23 December 2006 (UTC)
I appreciate the diagram. It probably answers a few questions, and so should be integrated into the article. My original question, "What do you mean?" is modified, having seen the diagram. If I understand correctly that the throughput for the ExpressCard is the total of 2.5 Gbit/s + 0.48 Gbits/sec for a total of 2.98 Gbits/sec, then it would help understanding the explanation -- eliminate possible ambiguities -- if the explanation included that total number.

With the increased speed, Firewire 800 (1394b) and SATA are the most interesting applications. They should be mentioned here. —Preceding unsigned comment added by 190.86.113.248 ( talk) 04:05, 4 December 2007 (UTC)
Is there just a single USB port per ExpressCard slot? Have any laptops shipped with two ExpressCard slots? Here's an idea I'll toss out for free. ExpressCard 68! Two 34mm wide slots side by side, able to run independently or with the second slot configurable just for additional PCIe data lanes so faster devices can be used when PCIe x1 speed is too slow. Or how about adding a second connector in the 54mm slot that has additional data lanes? ExpressCard 54X! To make that even better, have a loopback feature to the laptop's LCD driver (disabling and bypassing the built in video GPU) so that an upgraded videocard can simply be plugged into the slot, without requiring any external hardware and a separate monitor. —Preceding unsigned comment added by Bizzybody ( talk • contribs) 04:35, 30 December 2007 (UTC)
Because ExpressCards are pieces of hardware, technically they should be compatible with any operating system as long as it supports the ExpressCard, right? I have three specific ExpressCards in mind: one with a built-in card reader, one with a a pci express port, and another one with a broadband modem. Do you think guys think they would work regardless of the computer they are on? 69.122.137.56 ( talk) 21:30, 10 June 2008 (UTC)
There is a sentence in the article that says "This is an open standard by ITU-T definition which can be obtained from the ExpressCard website." This gives the reader the impression that the ExpressCard spec is an ITU-T standard. It isn't. If it was an ITU-T standard, it would be available from the ITU-T web site rather than some other web site. And it wouldn't cost $2500 to buy a copy. - Mulligatawny ( talk) 05:12, 5 April 2009 (UTC)
Adding a section about relatively poor consumer take-up of the ExpressCard Standard. Removing the two pictures of ExpressCard into PCMCIA slot adapters - yes they exist, but they have no relevance here. Centrepull ( talk) 11:05, 30 June 2009 (UTC)
The available power seems very limited. Please add details about this to the article. USB cards seem to not work very well because they can not pass through enough power. Such cards often offer aux connector for external power supply which is usually not supplied, and inconvenient in any event. This is a surprising limitation for a supposedly more modern connector standard. Seems to be a general problem with USB 2.0 expansion cards, particularly when used with external storage devices (hard drives etc). Is it also a problem for USB 3.0 cards? - 71.174.180.139 ( talk) 14:42, 2 June 2010 (UTC)
Going to the linked PCMCIA ExpressCard website yields the message that "the PCMCIA Association has been dissolved and the San Jose office closed. All activities and Standards, including the ExpressCard Standard and PC Card Standard, will be managed going forward by the USB Implementer's Forum." I don't pretend to be knowledgeable enough about these events to edit the entry, but I think it would be good if somebody who can put the situation in context would edit appropriately. —Preceding unsigned comment added by 24.87.65.232 ( talk) 23:51, 29 September 2010 (UTC)
Two times articles states that USB 3.0 cards are for ExpressCard 2.0 only. It is not true. Yes, EC2 have 1xPCIe 2.0 and USB 3.0, instead of just 1xPCIe 1.0 and USB 2.0, but nothing prevents from having PCIe chip providing USB 3.0 ports and speeds. Such card are common both for EC1 (where however it is limited to about 250MB/s from theoretical 400MB/s, maximum of USB 3.0. this is kind of problem if such card have two USB 2.0 ports, which limits their total speed to about 250MB/s from maximal 800MB/s) and EC2 (where it is limited by 500MB/s, which still can be limiting factor if using two USB 3.0 ports in such card - however such EC2 are essentially illogical, as for EC34 it is better to just use internal USB 3.0 port, and for EC54 it is better to have one port using internl USB 3.0 and one additional using 1xPCIe 2.0, which can provide 500MB/s which is sufficient to provide full USB 3.0 speed - 400MB/s). EC1 card commonly uses Renesas Electronics/NEC chips, like µPD720200, µPD720200A, and also µPD720202. All of this 3 chips have 2 USB 3.0 ports, and PCIe 2.0 interface (compatible with PCIe 1.0 and both EC1 and EC2). So actually all 3 can be used in PCIe 2.0 (or 1.0 of course), and is even faster, as can provide up to 500MB/s (still less than 800MB/s for two USB 3.0 port setup). — Preceding unsigned comment added by 91.213.255.7 ( talk) 12:25, 28 August 2011 (UTC)
what is the latest on the express card. and express devices. are they still in use, has there been any advances upgrades or are these dyng out. who can say really. I dont't know myself. — Preceding unsigned comment added by 121.98.109.199 ( talk) 11:26, 27 December 2012 (UTC) it seems that lots of new laptop models are missing expresscard slot and also fw port for example. but there is still so many expencive fw hardware, which users invested into. for me the interesting question is about the performance- do all expresscards provide the full performance for fw or does one have to be cautious about it? 90.157.168.26 ( talk) 09:40, 19 December 2013 (UTC)
