High Speed Memory Stick PROs are available, and newer devices support this high-speed mode, allowing for faster file transfers. The only advantage the Vaio adapter has is that it becomes part of your laptop if the laptop has an Expresscard slot, and thus you always have it with you.I've since then tested the microSD to Memory Stick Duo Adapter out with 1 GB microSD Card and it works just fine.

Images recorded on a Memory Stick XC-HG Duo media and SDXC memory card cannot be imported to or played on computers or AV devices that are not compatible with exFAT when connected using a micro USB cable. In October 1999, Sony licensed the technology to Fujitsu, Aiwa, Sanyo, Sharp, Pioneer and Kenwood, in a bid to avoid a repetition of the Betamax failure. As of January 2010 [update], it appeared that Sony had begun to combine support for SD/ SDHC and Memory Stick formats in their products. I pulled the adapter out, stuck it into a Sony MSAC-M2 Memory Stick Duo Adapter (the standard adapter that Sony bundle with Memory Stick Duo).For example, I've tried the Minolta CompactFlash Adapter for SD Memory Cards SD-CF1, the Sony MSAC-MCF1N Memory Stick Duo Adaptor for CompactFlash Slot, and the microSD-to-miniSD Adapter. The Vaio adapter does not read SDHC cards, however, making it not useful for much else other than memory sticks. Some early examples of Memory Stick usage by third-party companies include Sharp's MP3 players, Alpine's in-dash players, and Epson's printers.

In contrast, the Expresscard reader Sony Vaio VGP-MCA20 will only admit the full-size variants (though of course you can use an MS-DUO to MS Adapter here, something that does not work the other way round). A Memory Select version had two 128MB memory banks with a tiny switch for selecting one or the other.However, Sony did not abandon the format at this time, and indicated that it would continue development of the format for the foreseeable future. To use a Memory Stick Micro media with this product, be sure to insert the Memory Stick Micro media into an M2 Adaptor as large as Duo size.
