Magic Gate[edit]

How can you have a discussion of Memory Stick without discussing Magic Gate? It's mentioned in passing but that's all. (talk) 16:58, 27 June 2008 (UTC)

Does that mean that a Memory-Stick will work in a device that reads MMC?

No, they are completely incompatible formats, physically and otherwise. MMC will generally work in a device that reads SD, but not the other way around (SD is physically thicker than MMC.) Memory Stick only works with Memory Stick, but the newer, smaller, 'Duo' version will work in original Memory Stick devices when it is inserted into an adapter. 'Pro' sticks will not work in original Memory Stick devices. TBH I wish Sony would just give up on MS and use SD instead (typing this on a Vaio; I'd realan SD slot instead of my MS slot!) They may do this eventually, but it will be a long drawn-out effort; they have added Compact Flash to some of their top-end cameras (through necessity, due to the limitations on MS).

Memory Stick[edit]

Why is this article at "Memory stick" instead of "Memory Stick"? Isn't "Memory Stick" the proper name? If no one has objections, I will move it. --DropDeadGorgias (talk) 18:24, Mar 24, 2005 (UTC)

Indeed it should be called Memory Stick. -Towel401

Yes, certainly so. A.D.H. (t&m) 00:55, Apr 25, 2005 (UTC)

This article has been renamed as the result of a move request. violet/riga (t) 21:45, 27 Apr 2005 (UTC)

Shouldn't it be really named Memory Stink? :P -- 17:34, 14 December 2005 (UTC)

  • We don't take too kindly to trolls here.(Myscrnnm 06:26, 9 October 2007 (UTC))

Duplicate sentence[edit]

There are two sentences near the top that starts with "With a Memory Stick reader (typically a small box that ...". It seems that someone made an edit and forgot to alter the old bit. Who can find a good way to change it to something better?

Incorrect figures[edit]

Everywhere it says MiB, rather than MB, this is incorrect, since the memory sticks come in megabytes, rather than mebibytes.

No, that's actually correct. The binary prefix MiB (mebibyte) is 220 bytes. Flash memory sizes are always powers of two, so memory sticks are properly measures in MiB and GiB. Dgies 22:05, 13 July 2006 (UTC)

No, they're in powers of ten, a 1gb Memory Stick has 10^9 bytes on it, so it should go down as 1 gigabyte, etc.

Well, this is kind of trivial. Pretty much all manufacturers don't discriminate between MiBs and MBs because the difference is negligible for the consumer, so advertised capacities will often differ anyway.(Myscrnnm 06:28, 9 October 2007 (UTC))
Raw flash chips are generally measured in powers of two BUT actual accessible capacity of a flash based storage device is lower than the raw capacity of the flash due to the need for wear leveling. My experiance is that flash based storage devices have a capacity (as seen at the block device level) somewhere between the decimal interpretation and the binary interpretation of their headline capacity. (talk) 13:46, 26 March 2012 (UTC)

MB/s vs. Mb/s[edit]

I noticed that in one area, it says that the new Memory Stick Micro will have a maximum of 160 MB/s, and a little bit lower it states that it's 160 Mb/s. I'm assuming that the correct value is Mb/s, and I have since changed it. koolman2 22:14, 14 March 2006 (UTC)

Oh yeah, I think I changed that by accident.


i have a bunch of memory sticks but can not find out how much memory is on it can you help

The size can be usually inferred from the model number, written on the back, at least on the ones I own (all from Sony), e.g.: MSA-32A => 32MB, MSX-M1GST => 1GB. I might add some info regarding this, although someone with a bit more knowledge on the model numbers may do better. --Outlyer 17:54, 11 June 2006 (UTC)


i was looking for some basic information on sony's memory sticks, so i used a popular search engine, scrolled down, and read a nice introduction to this memory format. thanks.


Nc, apart from the information found on the article's introduction, I believe there is more information available on sony's memory sticks than what is being shown here. The overall information about the products is actually a bit out of date, since it does not comprise the Memory Stick PRO-HG Duo™ HX, only previous releases such as the Memory Stick PRO-HG Duo™ HC. The HX version was introduced in 2011, as pointed out here: Hope this helps! Many thanks, Zalunardo8 (talk) 10:48, 31 January 2013 (UTC)
Actually, I think we should update the page with this information. What do you guys think about including the following text in the 'Formats and form factors' section? ' Memory Stick PRO-HG Duo HX Sony announced the release of its new Memory Stick on May 17th, 2011 which would be presumably the fastest card ever made by the manufacturer. It measures 20 x 31 x 1.6 mm, with 8GB, 16GB or 32 GB versions available. Also, it offers a maximum transfer speed of 50 Mb per second. [1] ' Please, let me know what you think. Many thanks, Zalunardo8 (talk) 16:07, 31 January 2013 (UTC)


Any comments on the recording quality of memory stick vs. digital 8 videotape?

Primary purpose is recording basketball games for duplication to VHS and DVD along with the creation of highlight clips in MS Movie Maker.

It depends on the device you're using and the speed of the memory stick. Fast memory cards on the latest devices will have much higher recording quality than slow cards on older devices. —The preceding unsigned comment was added by (talk) 07:28, 8 February 2007 (UTC).


They say there are fake ones now! Most of which are "High Speed." Also should mention magicgate RealG187 20:53, 25 January 2007 (UTC)

There definitely are fake ones, and fake kinds of other memory cards too. Most of the ones I've seen were sold on ebay. —The preceding unsigned comment was added by (talk) 07:29, 8 February 2007 (UTC).


Are there adapters in existance, for example one that takes an SD-card and makes it compatible to interface with a Memory Stick-slot? —The preceding unsigned comment was added by (talk) 14:12, 5 February 2007 (UTC).

No, the formats are incompatible. SD only works on SD slots, Memory Stick only works on Memory Stick slots. —The preceding unsigned comment was added by (talk) 07:29, 8 February 2007 (UTC).

max 2GB[edit]

why does M2 Memory only seem to go up to 2GB? nobody appears to manufacture or sell any more than that, despite the limit of 32GB?

The limit is theoretical - meaning they can't yet manufature larger than a certain size becuase of technical limitations or cost. Bilky asko 14:47, 16 June 2007 (UTC)

  • I believe the theoretical maximum capacity of 32GB also applies to the standard original Memory Stick, and not the microscopic Memory Stick M2. However, you're exactly right in saying that we don't yet have the means to make Memory Sticks of 32GB capacity. Although Sony may have that technology, but from a business point of view, it would behoove them to not release memory cards with such large capacities just yet.(Myscrnnm 06:25, 9 October 2007 (UTC))

You can get 4GB from Sandisk now.

What's this about 2TB?! Where does this number come from? Does it take compression into account? (talk) 00:46, 29 December 2008 (UTC)

I edited out the parts about MS being "defined by it's proprietary nature" and about "Sony's stubborness" because I didn't think I was sufficiently NPOV. Especially since competing formats, exception of CF, are also proprietary. Stuck to the facts, about it being not as popular, used (mostly) only by Sony. Also created another section to move this out of the lead and keep the intro down to a summary paragraph, and broke the form factors part into subsections for each memory stick format. Makes it easier to read and edit. Acerimusdux 04:07, 4 March 2007 (UTC)

It is one of the few proprietary formats to have survived. It's lack of public documentation should probably be mentioned somewhere in the article. (talk) 20:14, 29 June 2008 (UTC)

SONY A100[edit]

I edited the use of Memory Stick to "sony digital cameras" to "sony digital compact cameras" since the new A100 Digital SLR camera actually has a CompactFlash slot.

MS & SD[edit]

From the article "It is not clear why Sony decided to diverge from established formats like Secure Digital, and many feel that Sony has done a disservice in introducing yet another flash media product that must be supported.". But wasn't SD released in 2000, a year and a half after MS was released in October 1998. Far from being established, SD had't even been developed when MS was released. Unless anyone objects, I'm removing it from the article. AlexJ 15:56, 27 August 2007 (UTC)

But there is another question: why didn't Sony use MMC in 1998, MMC was introduced in 1997. -- (talk) 16:17, 18 March 2008 (UTC)

Who makes Memory Sticks?[edit]

Are Sony and Sandisk the only manufacturers? Are some made by rebranders? I have seen photos of Pro Duo Memory Stick without any manufacturer name. Would they be definitively fake? -Wikianon (talk) 10:29, 11 January 2008 (UTC)

A long time ago I bought an IO Data branded Memory Stick. They still have some info about it on their website ([1] IO Data Website), though I don't know if it's a rebrand or not. Interestingly enough I was sold it at a Sony Central store. --Dylan (talk) 03:14, 19 January 2008 (UTC)
In addition to Sony and Sandisk, Lexar makes Pro Duo sticks. (talk)

Gaming sticks[edit]

from the article: The normal and PRO versions of Memory Stick Duo are also used with the PSP, which when inserted into the Memory Stick Slot show saved game data, music, pictures, videos and games.

So what is the reason for selling special gaming sticks like this one? —Preceding unsigned comment added by Qaywsxedc (talkcontribs) 19:29, 25 February 2008 (UTC)

Memorystick theorethical limit[edit]

Im sorry but the page says the theorethical limit is 32GB. Although most places say that it is true, i also heard and read in other areas that the therothical limit is 2TB, like the SDHC.

Maybe i should change it........ —Preceding unsigned comment added by Metallica10 (talkcontribs) 22:45, 21 August 2008 (UTC)

It would seem that someone has changed this to state 2TB. I'm concerned that this entire entry is short on references. Are there any good, referable, websites that actually state what the theoretical limit is?

(I wanted to comment on this but don't know how the signature is generated, sorry if I've broken standard etiquette. Gosh, darn those newbies.) —Preceding unsigned comment added by (talk) 06:26, 9 December 2008 (UTC)

Well, I actually changed this to 2TB (Heh, sorry for being late). The statement was only supported by comments, but here's an official announcement: [2] —Preceding unsigned comment added by Metallica10 (talkcontribs) 03:39, 20 April 2009 (UTC)

Potential Vandalism[edit]

In the infobox, it says that the Memory Stick's theoretical maximum capacity is 2 TB. Elsewhere, it says that 32 GB is the max. Is this vandalism? Ginbot86 (talk) 16:02, 19 September 2008 (UTC)

Apparently, Sony's stance is that 32 GB can currently be achieved, with 2 TB limiting the media at some undetermined point in the future. Perhaps this is the source of some confusion. (talk) 11:00, 21 June 2009 (UTC)

Compatibility; card to cameras[edit]

Can someone please tell me which other digital cameras take the Memory Stick PRO Duo Mark 2 card ? I currently have the Sony DSC-T50 Steadyshot and thinking about upgrading to another and would like to use this card. Am I limited to Sony cameras ? Davowolf (talk) 14:14, 13 September 2009 (UTC)

Needs Updating[edit]

There seems to be a lot of missing and incorrect information. Specifically, there is no mention of the Pro-HG Duo HX, and the information on the Pro-HG Duo seems to be incorrect--it states that it's transfer speed is three times that of the Pro Duo, but Sony's website states that the Pro-HG Duo HX has three times the speed of the Pro Duo. It could be that they are comparing different speeds, e.x. transfer/read/write. —Preceding unsigned comment added by Darktangent (talkcontribs) 21:57, 23 September 2010 (UTC)

another name for DIMM card? or whatever memory for motherboard slots is called now[edit]

please add another disambiguation link pointing to just RAM memory, as packaged on "sticks" that one installs in slots on motherboards? — Preceding unsigned comment added by (talk) 16:27, 27 April 2012 (UTC)

microSD to Memory Stick Pro Duo adapter[edit]

What about microSD to Memory Stick Pro Duo adapters and its limitations? — Preceding unsigned comment added by (talk) 06:30, 9 December 2012 (UTC)

wifi claim[edit]

"A prime example is the development of WiFi transfers through a special Memory Stick Pro-Duo which is still in development." Where does this come from? None of the citations make any reference to wifi. (talk) 16:12, 30 January 2013 (UTC)

PRO or Pro?[edit]

This article capitalises Pro throughout, e.g. Memory Stick PRO Duo. However, Wikipedia style is to ["choose the style that most closely resembles standard English, regardless of the preference of the trademark owner"], which would surely be Memory Stick Pro Duo, unless it's an acronym that I'm not aware of. Is there any reason for this styling or should it be changed?
