Sandisk zet in op CFast 2.0 (650 MB/s) in plaats van XQD

Door -

Gisteren werd een nieuwe specifcatie van de CFast-standaard aangekondigd. Versie 2.0 is goed voor schrijf- en leessnelheden van maximaal 650 MB/s, al zal de praktijksnelheid in eerste instantie op circa 350 MB/s uitkomen. Dat is een stuk sneller dan de eind vorig jaar nieuw aangekondigde XQD standaard..CFast lijkt qua specificaties de ideale opvolger van CompactFlash. Dat stelde Susan Park van Sandisk in een gesprek met FotoVideo.nu. De CFast standaard bestaat al enige tijd (toen nog versie 1.0), maar tot nu toe zijn er nog geen camera die het ondersteunen. Versie 2.0 is geheel ´futureproof´ en lijkt daarmee klaar voor de uitrol. Susan verwacht dat de kaartjes nu echt binnenkort op de markt komen, maar durft vanwege ´forward looking statements´ (Sandisk is beursgenoteerd) geen harde datum te noemen. 

Voor video en DSLRs

De CFast-kaartjes zijn ontwikkeld met video en high speed DSLR´s. Met name voor 4K video is CFast interessant vanwege de hoge doorvoersnelheden. Met 30 beelden per seconde vergt 4K video al snel 200 tot 250 MB per seconde en dat halen reguliere geheugenkaartjes zoals CompactFlash en SD nog niet, al ligt er wel een nieuwe specificaties van SD klaar die meer dan 300 MB/s haalt. Het maximum van de huidige generatie CompactFlash-kaarten ligt op 167 MB/s en dat is dus te weinig voor 4K video. 

XQD vs CFast

Maar hoe zit het dan met het recent aangekondigde XQD? Sony, Nikon en Lexar hebben daar al hun steun voor XQD al toegezegd. Sandisk stelde dat Canon en Phase One hun ondersteuning voor CFast hebben toegezegd, al betekent dat feitelijk niet dat er binnenkort ook een product beschikbaar komt. Alleen Nikon ondersteunt momenteel XQD met de D4 (die overigens ook CF-kaartjes slikt). De maximale praktijksnelheid van XQD ligt momenteel in de praktijk op 168 MB/s (op basis van kaartjes van Sony), De maximale theoretische snelheid zou overigens ook in de buurt van de 600MB/s uitkomen. 

In het hogere segment lijkt dus sprake te yijn van een nieuwe standaardenstrijd als het om high end geheugenkaarten gaat. CompactFlash is momenteel de standaard, maar zal in 4K producten plaats moeten maken voor ofwel XQD of CFast 2.0. Ook is het aannemelijk dat professionele DSLR´s gebruiken zullen maken van een opvolger van CompactFlash, zoals Nikon dat al doet met de D4. Sony produceert wel al XQD geheugenkaarten, maar gebruikt ze niet in haar topmodel, de A99. Canon lijkt nog geen definitieve keuze te hebben gemaakt (de dit jaar uitgekomen 1D X heeft twee CompactFlash-sloten).

SANDISK ANNOUNCES DEVELOPMENT OF CFAST MEMORY CARDS FOR NEXT-GENERATION PROFESSIONAL PHOTO AND VIDEO APPLICATIONS

  • New specification delivers up to four times faster performance than current CompactFlash® memory cards used in today’s professional-grade cameras
  • Ideal for next-generation cameras offering high resolutions and featuring advanced professional video recording applications
  • Currently sampling CFast2.0 memory cards to camera manufacturers as they design and optimize their next-generation host devices for CFast2.0

PHOTOKINA, Cologne, Germany, September 18, 2012SanDisk Corporation (NASDAQ: SNDK), a global leader in flash memory storage solutions, today announced that it is developing flash memory cards based on the new CFast2.0 specification introduced today by the CompactFlash Association (CFA). The new specification enables next-generation photo and video applications by delivering up to four times faster performance than the CompactFlash memory cards currently used in DSLR cameras and other imaging devices.

“CFast2.0 memory cards will help drive the future of professional photography and video-recording applications,” said Shuki Nir, senior vice president and general manager, Retail, SanDisk. “With the CFast2.0 specification’s unparalleled performance, flash memory can now enter new markets such as high-definition TV and even cinema production.”

Ideal for Next-Generation Professional Video Applications
Professional video applications are growing more powerful than ever before, with 2K video enjoying widespread use and full-frame 4K video already gaining adoption in high-end production environments. These next-generation video applications can produce videos with incredibly high resolutions and large file sizes. The CFast2.0 specification supports advanced video applications through higher interface bandwidth and much higher levels of Video Performance Guarantee to meet the requirements of 2K/4K digital intermediate compressed production environments.

“Professional photographers, videographers and cinematographers demand increasingly powerful cameras that help them unleash their creativity,” said Masaya Maeda, managing director and chief executive, image communication products operations, Canon. “With extremely fast performance, CFast2.0 memory cards will enable us to develop next-generation cameras with more powerful features than are currently supported by CompactFlash cards.”

Ideal for Next-Generation Photography Applications
Digital cameras are expected to become more powerful, with the ability to capture images at greater than 40MP resolution. These next-generation cameras will produce photos of unprecedented quality, and the large file sizes can quickly overwhelm a CompactFlash memory card’s data-transfer rates and halt shooting.

The CFast2.0 specification features theoretical performance of up to 600MB/sec, four times faster than the highest-performance CompactFlash memory cards. The new specification delivers the fast speed needed to capture a series of high-resolution photos and transfer them quickly to a computer, particularly important to professional photographers whose workflows demand the utmost efficiency.

“PhaseOne believes in open standards where many players have access to the technologies required to create a healthy ecosystem and drive the future of imaging,” said Henrik Håkonsson, chief executive officer, PhaseOne, a leading medium format camera manufacturer. “We intend to integrate CFast2.0 memory cards into our new cameras because they offer significantly higher recording performance and faster offload speeds than other memory card formats.”

Sampling Now
SanDisk is currently sampling CFast2.0 memory cards to camera manufacturers as they design and optimize their next-generation host devices for the new specification.

The CompactFlash Association Announces CFast 2.0 Draft Specification

CFast2.0 Introduces SATA-3 Format Capable of Up to 600MB/sec

Cupertino, California – September 18, 2012 – The CompactFlash Association (CFA) announces the CFast 2.0 draft specification and celebrates seventeen years of performance leadership in flash memory card markets. The CFast 2.0 draft specification was approved by the CFA Board of Directors for a 90 day final approval vote by all voting members. General availability of the CFast 2.0 specification for non-members is expected in Q4 of 2012. The CompactFlash Association was formed in 1995 as the initial digital film format and continues to serve professional imaging markets where high performance and high quality recording media are important. CFA has consistently created specifications to meet the current and future requirements for professional imaging and video markets. CFast2.0’s performance capability of up to 600MB/sec enable CFA to serve new professional video markets such as high definition TV production and cinema video production environments.

CFast 2.0 leverages the SATA-3 interface for higher performance based on a computing industry storage interface and protocol. Host manufacturers will be able to leverage their experience and investment in the ATA storage protocol and media manufacturers will be able to leverage high volume solid state disk (SSD) controller technology to serve the high performance requirements of this market. The new format will have VPG (Video Performance Guarantee) capability with profiles capable of supporting compressed digital intermediate video formats.

Professional video features are growing more powerful, with 2K video enjoying widespread use and 4K video already gaining adoption in high-end production environments. High Definition TV production environments require digital intermediate compression formats where 2K @ 120 frames per second requires reliable performance of 200MB/sec to 250MB/sec. 4K production environments require 4X the data rates of 2K. For example, 4K at 30 frames per second also requires 200MB/sec to 250MB/sec. These next-generation video applications produce videos with incredibly high resolution that exceed CompactFlash cards’ data recording maximum capability of 167MB/sec for CF6.0.

The new CFast2.0 specification is available to members and will be available for purchase by non- members after the IP review period closes in the fourth quarter of 2012. Key features of CFast2.0 include:
