Compact Flash da 500MB/s!

jl_cfa_brandID_02

Se credete che il numero di pixel dei sensori dell’ultima generazione sia abbastanza per catturare immagini sufficientemente dettagliate oppure che il FullHD vi possa bastare ed avanzare, beh pensate male. Almeno nelle intenzioni infatti i tre colossi SONY, Nikon e Sandisk, membri fondatori della CFA (Compact Flash Association), hanno in mente ben altri piani: rompere l’attuale barriera dei 167MB/s dei supporti di memorizzazione CF per arrivare alla soglia dei 500MB/s. Tutto questo permetterebbe flussi dati ben tre volte maggiori, a tutto vantaggio di sensori con risoluzioni pił elevate e cattura di filmati HD presumibilmente anche in qualitą RAW video. Capacitą delle memorie e potenza degli elaboratori (preparate il portafogli) cresceranno di conseguenza… of course! E a proposito di dimensioni delle memorie, il nuovo standard proposto arriverebbe fino a 2 terabyte (!): mi ricordo ancora quando una memoria da 128MB sembrava avere una capacitą mostruosa…

Press Release Ufficiale (in lingua inglese)

SANDISK, NIKON AND SONY PROPOSE INDUSTRY STANDARDS FOR NEXT-GENERATION HIGH-SPEED MEMORY CARD FORMAT

Companies Jointly Develop New Specifications to Meet Needs of Professional Photography and Video Markets

Milpitas, Calif., November 29, 2010-SanDisk Corporation (NASDAQ:SNDK), Nikon Corporation and Sony Corporation today announced the joint development of a set of specifications that addresses the future requirements of professional photography and video markets. The three companies proposed the specifications to the CompactFlash® Association (CFA)1, the international standards organization, with the intent to standardize the format.

Professional photography and High Definition (HD)2 video applications require a new generation of memory cards capable of processing significantly larger files. To address the imaging industry’s future speed and capacity demands, SanDisk, Nikon and Sony proposed a new card specification whose performance and storage capabilities surpass those of existing memory cards. Once accepted, the new format will enable exciting new possibilities in the professional imaging and video markets.

The proposed specifications achieve data transfer rates of up to 500 megabytes per second (MB/sec)3 (theoretical maximum interface speed) using the highly versatile PCI Express4 interface. The increased speeds will enable imaging and video applications that could not be accomplished using the current CompactFlash specification’s Parallel ATA (PATA)5 interface. CF6.0, released in November 2010, offers maximum performance of up to 167MB/sec.

The new specifications’ faster speeds enable continuous burst shooting of massive RAW images. The enhanced performance also allows users to quickly transfer storage-intensive high-resolution photos and videos from the card to a computer. The specifications combine high-speed data transfer with low power consumption via a power scaling system to extend battery life.

In addition to industry-leading performance capabilities, the new memory card specifications also meet the future capacity and durability requirements of professional imaging applications. The proposed new format has the potential to extend theoretical maximum capacities beyond two terabytes (TB)6, making it especially useful for high resolution images and HD video applications. Similar in size to a CompactFlash® card, the new format’s access control function and highly durable form factor produce a combination of physical ruggedness and reliability that is indispensable for professional usage models.

“This ultra high-speed media format will enable further evolution of hardware and imaging applications, and widen the memory card options available to CompactFlash users such as professional photographers,” said Mr. Shigeto Kanda, Canon, and chairman of the board, CFA. “This next generation format is expected to be widely adapted to various products, including those other than high-end DSLRs.”

“The ultra high-speed media, which will be realized by this new card format, will expand the capability of digital SLR cameras and other professional digital imaging equipment,” said Mr. Kazuyuki Kazami, operating officer, vice president and general manager, development headquarters, imaging company, Nikon Corporation.

Notes
1 CompactFlash Association (CFA) is an international standards organization developing specifications for CompactFlash products.
2 Full HD (1920X1080X30fps, HD & 3D video support may vary based upon host device, file size, resolution, compression, bit rate, content and other factors.
3 Based on SanDisk internal testing; performance may be lower depending upon host device. 1 megabyte (MB) = 1 million bytes.
4 PCI Express is a serial interface, a computer expansion card standard.
5 ATA(Advanced Technology Attachment) or PATA (Parallel ATA) is an interface standard between PC and storage devices
6 1 terabyte (TB) = 1 trillion bytes.
