Quelle carte mémoire MS ? - Memory Stick inside

[Hawkeye]

Bonjour,

Voilà ma question portera surtout sur les Memory Stick. J'ai déjà des CF Sandisk Ultra II et Extreme III.

Je vais continuer à utiliser mes CF. Je pense mettre et laisser en permanence une carte Memory Stick dans le slot prévu (pour dépanner). Mais que prendre ? Il y a plusieurs formats supportés par l'alpha 700. MS Duo / MS Pro Duo et MS-PRO HG.

Est-ce que vous utilisez des MS dans votre alpha 700, si oui en êtes vous content ?
J'ai entendu dire qu'elles étaient moins performantes que les CF en écriture.

Quelle marque faut-il privilégier ? Sandisk ou Sony ?

Quelle est le type de MS le plus performant (je me doute bien que c'est le HG) ?

Merci pour vos lumières

Quelle est le type de MS le plus performant (je me doute bien que c'est le HG) ?

Je me répond à moi même, voici ce que j'ai trouvé sur le site de Sony :

http://www.sony.net/SonyInfo/News/Press/200612/06-1211E/index.html

SanDisk Corporation (NASDAQ: SNDK) and Sony Corporation today announced the development of the "Memory Stick PRO-HG" format expanded from the "Memory Stick PRO" format.

The continuing increase in the capacity of IC recording media has broadened its usage as a practical way to store high-resolution digital photos, music and video content (from the Internet or TV programs) on portable devices that are designed to handle digital entertainment content. The demand for real-time recording and transfer of multiple gigabytes of data using IC recording media is expected to increase rapidly, due to the growing popularity of high resolution video and digital still image applications.

"Memory Stick PRO-HG" media offers high performance to meet the stringent demands of end users. This new media format uses an enhanced, 8-bit parallel interface in addition to a conventional serial and 4-bit parallel interface. The interface clock frequency also increases to 60MHz from 40MHz. This means that maximum data transfer speed increases up to 480Mbps, or 60MB/s (theoretical value), three times as fast as that of "Memory Stick PRO" media. The minimum write speed at 8-bit parallel transfer is 120 Mbps, or 15MB/s. These enhancements allow large data amounts of up to several gigabytes to be quickly transferred, as well as the real-time recording of high-resolution video and still images.

Since "Memory Stick PRO-HG" is an extended format of the "Memory Stick PRO" format, "Memory Stick PRO-HG" compliant host devices support the conventional "Memory Stick PRO" media as well as "Memory Stick PRO-HG" media. In addition, the "Memory Stick PRO-HG" media can be used conventional "Memory Stick PRO" compliant host devices as well as "Memory Stick PRO-HG" compliant host devices.

Licensing for the development of "Memory Stick PRO-HG" compliant host devices is scheduled to commence in January 2007.

Et bien personnellement, j'utilise une MS pro duo (sandisk) de 4 Go. Je ne l'utilise qu'en cas de besoin (c'est à dire quand ma CF est remplie).

Si ton but est de l'utiliser comme une carte de secours, prends tout simplement la moins cher.
