SDHC UHS Speed Class 3 cards for 4K
  • Vitaliy_KiselevVitaliy_Kiselev

    SD Association have announced a new high-performance option and symbol specifically designed to support a wide array of 4K2K television and video products.

    A new Ultra High Speed (UHS) Speed Class 3 (U3) symbol will indicate products capable of recording 4K2K video and will operate exclusively on SDXC UHS-I and UHS-II memory cards and devices and SDHC UHS-I and UHS-II memory cards and devices.

    The UHS Speed Class 3 defines a sizzling fast 30 Megabytes per second constant minimum write speed to ensure high-quality video recordings. This means 4K2K video, live broadcasts and content can be recorded on high-performance cameras such as Digital Single Lens Reflex (D-SLR), Digital Single Lens Mirrorless(DSLM), camcorders and video cameras and then played back smoothly. Consumers will benefit from a single card that is capable of meeting all of their video, photo, music, document and data storage needs.

    “The world’s favorite SD memory card continues to evolve and meet shifting industry needs,” said Brian Kumagai, president of the SD Association. “Our new UHS Speed Class 3 standard will give consumers and businesses more flexibility and capability as the market shifts to 4K2K video formats. Both SDXC and SDHC memory card standards already offer the massive storage needed to support 4K2K video with enough room to store photos, music, documents and other data on a single portable card.”

    New devices offering the UHS Speed Class 3 will be backwards compatible and will work with existing SD memory cards.

    New standard speed between the memory card and the device can be up to 312 Megabytes per second.

    SanDisk are owned by much more people, more widely present and known.

    The safest choice for 1080p 25fps ALL-Intra 200Mbps seems to be still the SanDisk Extreme Pro 64 GB SDXC memory card (280 MBps, Class 10, UHS-II, U3) I guess?

    Transcend 600x gets bad reviews online.

    very sad. still no real RAW card out there for BMPCC except the sandisk it seems. I read about PNY Red Elite cards, but they are almost as expensive.

  • _gl_gl

    (sorry, wrong thread)

  • _gl_gl

    Not massively cheaper than the SD Extreme Pro, but still nice if it works. Not many people selling it yet in UK:

    Amazon UK: £65 (from Amazon): http://www.amazon.co.uk/Transcend-Ultimate-Performance-UHS-I-Memory/dp/B00J3KA9HC/ref=sr_1_9?s=computers&ie=UTF8&qid=1406064854&sr=1-9&keywords=transcend+uhs-3

    Ebay (Hong Kong, no 'fake' feedback) £51: http://www.ebay.co.uk/itm/Transcend-64GB-SDXC-Ultimate-95MB-s-85MB-Write-C10-64G-64-G-GB-SD-XC-UHS-I-U3-Ne-/321410886874?pt=UK_Computing_FlashDrives_SM&hash=item4ad594ecda

    Worldwide lifetime warranty (used it once on an old card, no issue getting it replaced by Transcend UK).

    ADATA Launches SDXC UHS-I Speed Class 3 (U3) Memory Cards

    Supports 4K Ultra HD Video Capture

    ADATA™ Technology, a leading manufacturer of high-performance DRAM modules and NAND Flash application products, announces the launch of XPG and Premier Pro series SDXC UHS-I Speed Class 3 (U3) memory cards. Compared to the UHS-I U1, write speeds are increased by 750% and 500%, respectively. Both series are designed to support the latest UHS-I U3 specifications, enabling the cards to capture professional grade high-quality images as well as smoothly transfer large files without any time gaps.

    As demand for ultra-fine quality video continues to increase, the 1920 × 1080 pixel resolution of Full HD in the past has quickly evolved into the 4K Ultra HD high resolution standard (3840 × 2160). High-quality video recording creates larger files which require more disk space, presenting challenges to the operation and load bearing capacity of recording equipment and storage media. ADATA XPG and Premier Pro SDXC UHS-I U3 are specifically tailored to 4K2K ultra-high definition devices, and deliver outstanding speeds of up to 95/85 MB/s and 95/60 MB/s, respectively. The SDXC UHS-I U3 cards are ideal for burst mode photography and high resolution videos to capture each fantastic moment with the utmost precision.

    According to the SD Association, the UHS-I Speed Class 3 (U3) must achieve a minimum write speed of 30MB per second and support UHS-I U3 photographic equipment specifications to deliver optimal capacity. ADATA XPG and Premier Pro series SDXC memory cards are based on the UHS-I U3 standard and provide users with next-level performance. ADATA SDXC UHS-I U3 cards have been tested under extreme conditions, and come with a lifetime warranty. The XPG series provides 64GB of storage capacity and the Premier Pro series is available in both 64GB and 128GB.

    @mpgxsvcd I'm wondering the same thing about the 128gb Transcend card. I guess you'll find out in a couple of days huh?

  • kevin_kirchmankevin_kirchman

    @mpgxsvcd You got the transcend working in a GH4 (both 4k and 200mbps 1080p) or just in theory it should work?

  • kellar42kellar42

    I use a Florida address to get things to Panama, so the U.S.

  • mrbillmrbill

    @kellar42 - shipping to where?

  • kellar42kellar42

    I'm a little confused by all of this...Amazon seems to think the extreme pro Sandisks I already have will work, but there is a new Sandisk linked to here which cannot but immediately shipped from anywhere that seems very powerful. I bought a kingston that is the recommended accessory just to have an option in case what I have doesn't work. If anyone has a link to a sure thing top of the line that is shipping NOW, please let me know.

  • karlkarl

    I wonder whether the microcontrollers in those new fast SD cards will at some point have enough computing power to allow for funky hacks like "let the SD card merge some images written in succession" (as in focus stacking or alike).

    Here's an interesting article on hacking SD card controllers.

  • Vitaliy_KiselevVitaliy_Kiselev

    Extending its industry leadership in memory card solutions, Toshiba America Electronic Components, Inc., a committed leader that collaborates with technology companies to create breakthrough designs, has introduced the world’s fastest microSD memory cards. The new cards are the first in the industry to comply with the UHS-II interface standard, the ultra high speed serial bus interface defined in the SD Memory Card Standard Ver. 4.20. Available in 32GB and 64GB capacities, Toshiba’s new microSD memory cards offer the fastest transfer rates available, are UHS Speed Class 3 (U3) enabled, and allow high-quality 4K video capture at constant minimum write speeds of 30MB/s. This means that 4K2K video, live broadcast and content can be recorded on high-performance cameras.

    The 64GB cards offer a maximum read speed of 260MB/s and a maximum write speed of 240MB/s. The 32GB cards have a maximum read speed of 145MB/s and maximum write speed of 130MB/s, which represents an 8x write speed improvement and 2.7x read speed improvement when compared to Toshiba’s current 32GB microSD UHS-I cards (5). These faster transfer speeds reduce the time required to download large data movie and music files to smart phones and tablets, and enable camera users to shoot high resolution digital still images in a continuous high speed shooting mode.

    My UPS guy just delivered my Transcend 128GB UHS-1 SDXC Memory Card (Speed Class 3) from B&H today so now I wait for my GH4 from them. https://farm8.staticflickr.com/7100/13761583664_a89cb2f40b_b.jpg

  • mpgxsvcdmpgxsvcd

    I got the Transcend card today. It works as advertised. Plenty fast enough for GH4 and dirt cheap.

  • mpgxsvcdmpgxsvcd

    @aldolega

    GoPro recently put Sandisk on their blacklist. Basically GoPro publicly stated that Sandisk cards don’t write at their stated data rates. GoPro put out firmware that dumbs the camera down if a Sandisk card is inserted.

    Basically any of these companies can make bad cards including Sandisk. The best way to handle it is to not overspend on the cards and buy several of them instead. Any card can fail at any given moment no matter how much you spent on it.

    Be prepared to switch out cards at a moment’s notice and also be prepared to lose footage. Limiting the impact of those losses is what will be the best option.

    FYI, Kingston is one of the biggest RAM manufacturers in the world. http://en.wikipedia.org/wiki/Kingston_Technology

  • aldolegaaldolega

    I try to stay with SanDisk because I've read that they are one of the only companies that actually make their own cards/memory, and it seems to me like they would pawn the stuff that fails QC off on the other brands they supply memory/cards for. Maybe this is true, maybe not, but to me, it seems silly to skimp on cards to save a few bucks when I've spent thousands on everything else.

  • AdamTAdamT

    I got one of the Kingston 64GB U3 cards and I had the feeling that files were transferring much faster over my USB3 card reader. Just did a comparison to my Transcend 32GB Class 10 card and found that copying a 1.3GB file from my desktop to the card is almost 7X faster with the Kingston card (21s vs. 1m 20s). Going the other way the speed increase seems about the same.

  • mpgxsvcdmpgxsvcd

    It looks like the “Standard”(Not Extreme 60 MB write speed) versions of the Transcend cards are shipping now. My 64 GB card should be here on Thursday.

    I didn’t get the 128 GB version because the battery won’t last that long. I don’t mind swapping out the memory card at that the same time as the battery. I will buy several of these 64 GB cards if they work in the GH4 ok.

    You can get a 128 GB 600x Transcend card for $95 that theoretically should work in the GH4 as well. I will get one of those when the GH4 ships just to try it.
