cards

My new SDXC card of choice is the Lexar 64GB UHS-II technology (U3) for a read transfer speed up to 1000x (150MB/s).

Only SDXC class 10 speed 3 cards will be fast enough to use with the GH4 if you plan to film in 4K, remembering 4K takes a lot more memory than simple HD footage.

Transcend Information, Inc. (Transcend®), a worldwide leader in storage and multimedia products, is proud to announce its launch of SDXC/SDHC UHS-I cards featuring full support for the Ultra High Speed Class 3 (U3) specification. Capable of reaching incredible read and write speeds of up to 95MB/s and 85MB/s, Transcend’s SDXC/SDHC UHS-I U3 cards provide the performance necessary to harness the full power of UHS U3-compliant digital recording equipment.

Cinema-Quality 4K Video Recording

Recently released by the SD Association, the Ultra High Speed Class 3 specification guarantees a minimum constant write speed of 30MB/s to facilitate cinema-quality video recording. Transcend’s SDXC UHS-I U3 and SDXC/SDHC UHS-I U3X “Extreme” cards, however, can achieve at least double this performance with blazing-fast write speeds of up to 60MB/s and 85MB/s respectively. When used with today’s advanced camcorders, such as the Sony® 4K Handycam® FDR-AX100, Panasonic® Lumix® DMC-GH4, and Canon® EOS® C500 Cinema Camera, these cards ensure smooth 4K video capture in stunning color and clarity.

Quick and Seamless File Transfers

In devices that do not support the UHS-I specification, Transcend’s SDXC/SDHC UHS-I U3 cards offer constant write speeds of at least 10MB/s (SD Speed Class 10 performance), which makes them perfect for Full HD video recording as well as fast-action consecutive shooting. Pairing the new UHS-I U3 cards with Transcend’s RDF8 USB 3.0 multi-card reader or the handy RDF5 USB 3.0 card reader with built-in USB port significantly reduces the time it takes to transfer data from card to computer with read speeds of up to 95MB/s.

Enormous Storage Space Up to 128GB

Featuring capacities ranging from 32GB to an enormous 128GB, Transcend’s UHS-I U3 memory cards are fully equipped to handle the increased capacity requirements of professional photography and filmmaking. For instance, the 128GB SDXC UHS-I U3 card can store more than 20,000 high-resolution JPEG images (12 megapixel camera, 6MB file size), over 8,500 RAW images (based on 14MB file size), or a full 8 hours of 4K Ultra High-Definition footage (4096×2160 35Mb/s H.264 AVC compression). Moreover, Transcend’s SDXC UHS-I U3 cards make extended video recording sessions possible thanks to the use of the exFAT file system that allows users to exceed the 4GB size per file limit of FAT32.

Free RecoveRX Software

For added value, each Transcend memory card includes a free download of Transcend’s exclusive RecoveRx™ photo recovery software – an extraordinarily effective tool for bringing back accidentally deleted or lost files. All Transcend memory cards are fully tested for compatibility and reliability, and carry Transcend’s renowned Lifetime Warranty. The SDXC UHS-I U3 cards (R95MB/s, W60MB/s) are available in 64GB (US$49) and 128GB (US$109) capacities, while the SDXC/SDHC UHS-I U3X cards (R95MB/s, W85MB/s) are available in 32GB (US$59) and 64GB (US$119) capacities.

    While researching what SD card might be best for my GH4 purposes, I have discovered that SD card descriptions can be wildly confusing. For example, HC vs XC, read vs write, peak speed vs sustained speed, Mbps vs MB/s, Specification I vs Specification II, etcetera.

    Also during my research, I see that SanDisk has just released a new Extreme Pro SD card speed U3 rated at 280 MB/s. At first blush, this seems to be leading edge performance. However, this card is Specification II.

    If my reading of the GH4 manual is correct (and also if the manual itself is correct), the above SanDisk card may not be compatible with the GH4. Page 22 of the manual specifically says the camera is compatible with UHS I speed 3 and the new SanDisk card is UHS II speed 3. Perhaps the card will work with the GH4, but at a reduced speed since the camera will not accommodate the additional connection pins of UHS II. But if that is the case, why pay the vast price premium and not enjoy full performance of the card?

    Which returns me to my original question. What is (or will be) the most reliable and best value SD card for recording 4K on the GH4?

    HDW : I have always found SDXC cards to be a bit more nippy than SDHC cards and the price of the new Transend SDXC U3 64G at £26 is unbeatable value for money. I do wish these card manufacturers would all adhere to the same protocol instead of 600x like Lexar which tells you nothing and keep it to read/write speeds.

    Hi,

    I can’t find this anywhere! How do you check how much space is left on the card? Truly stumped me!

    Cheers

    HDW : I am looking into this for you.
