Need Cheap device to backup SD-cards on the go. Ideas? Sun, 05 Mar 2017 12:43:29 -0700 fatpig 16545@/talks/discussions I have been looking at the WD MyPassport Drives for some time to backup SD cards to a 2.5 in HDD on set or on travels. They have an inbuilt SD slot and can do a backup without a Computer.

But: It only copies at around 55mb/s speeds and its still quite expensive ( 160$ for 2TB version ) Has anyone looked at cheaper, smaller devices like Raspberry Pi, android devices, etc - that feature USB3.0 for data backup to an external HDD? Obviously, Usb2 speeds are not of interest here.

UHS-III memory cards coming with 624MB/sec speed Thu, 23 Feb 2017 20:14:32 -0700 Vitaliy_Kiselev 16502@/talks/discussions

Pacifico Yokohama, Japan — CP+ Camera and Photo Imaging Show Booth # G-16 — Feb. 22, 2017 — The SD Association announced today UHS-III, doubling the fastest SD memory card transfer rate up to 624 megabytes per second (MB/s). UHS-III faster speeds help move large amounts of data generated by data-intense Gbps wireless communication, 360-degree cameras, drones, 3D, 4K and 8K videos recorded on SDXC and SDHC memory cards.


Immense storage capacities introduced with SDXC memory cards give users the ability to take more pictures and make unique video features on the latest imaging devices. Fast UHS bus interfaces help users manage that content more quickly. Since it is fully backwards compatible, devices offering UHS-III bus interface will accept the billions of existing SD memory cards in the market today.

“SD memory card capabilities continue to expand, paving the way for new and highly anticipated imaging and video features, from virtual reality to 8K video,” said Brian Kumagai, SDA president. “The SDA remains committed to supporting innovation by consumer electronics manufacturers and to delivering the same performance and interoperability consumers and professional users love about SD memory cards.” The SDA released a visual mark to denote UHS-III SD memory cards for easy matching with devices’ recommendation for the best SD memory card for optimal performance.

The UHS-III high-speed interface signals are assigned to the second row of SD memory card pins introduced with UHS-II. This newest bus transfer speed option will be available in full-size SDHC and SDXC cards, as well as microSDHC and microSDXC cards. It does not change the physical size or shape of the cards as the move from UHS-II to UHS-III involves only a PHY change, allowing relatively easy and fast upgrades of existing UHS-II products to UHS-III.


Both UHS-I and UHS-II make the robust storage specified for SDHC and SDXC manageable and even more portable. Ultra High Speed was announced in June 2010 with UHS-I delivering top bus-interface speeds of 104 MB/sec, which was tripled to 312 MB/sec in UHS-II. UHS bus interfaces are backwards compatible and are exclusive to SDXC and SDHC products. All UHS-equipped memory cards achieve greatest performance when paired with corresponding UHS devices. SDXC and SDHC UHS-I and UHS-II products are already in retail outlets around the world and supported by leading camera manufacturers. You can read more about UHS on our website.

TLC and MLC difference in cheap SSDs Mon, 31 Oct 2016 19:39:20 -0600 Vitaliy_Kiselev 15972@/talks/discussions image

Two cheap (not absolute bottom, Phison PS3110-S10, small size - 120GB, so speed is smaller) SSD drives, one is MLC (on left) and one is on TLC (on right). Sequential writing scenery.

As soon as SLC buffer in TLC disk ended write speed dropped to below HDD level.

Read speed is ok on both, nothing to worry.

SD cards speed tests Wed, 09 May 2012 07:50:51 -0600 humpman 3152@/talks/discussions Here are the simple instructions.

  1. Download HD_Speed zip file from
  2. Extract the HD_Speed.exe executable from the zip file and start it. It may hang for a while (Not Responding) when it starts up because it is scanning your system for drives but eventually will become available.
  3. Set the parameters to Bits/Sec, BlockSize=32KB, Mode=Write and Duration 01:00.
  4. Insert your blank SD card in your computer. HD_Speed will destroy all data on your card.
  5. Choose the appropriate drive letter in HD_Speed and run the test. Be careful here, don't choose your other drives. When you're done, you'll want to format your card before using it.
  6. Report your results in Mbps along with the following information:
  • Card Reader
  • Card Brand
  • Card Type (SD or SDHC or SDXC)
  • Card Class
  • Card Size (in GB)
  • Date Purchased
  • Card Write Speed (in Mbps) Current and Average
External hard drive for editing video Fri, 06 Jan 2017 13:26:16 -0700 PeteK 16294@/talks/discussions Hey everyone! What do you guys recommend as a good external hard drive for editing videos on a late 2012 iMac with a 2.7 GHz intel core i5 processor using FCPX? I have been making videos for a while now and I've been looking at getting an external to make editing faster and less taxing on my computer. However, every higher end hard drive I have come across has had mixed reviews and I can't seem to make up my mind. I currently do short films which are shot on the GH2 with Sanity X on it. I may try different hacks such as driftwood and flowmotion later on. My films usually range from 2-10min long so nothing too big. I'm mainly looking for speed as opposed to storage and it would be amazing if I could find one for under $150 as I am hoping to get a new lens also :D. Any advice and suggestions would be greatly appreciated! Thanks in advance!

BD-R one time readable Sun, 20 Nov 2016 04:13:01 -0700 davjd 16070@/talks/discussions I'm having a strange and weird problem. I create a BD-R (video) disc with encore. The blu ray is readable by any home blu ray player (as far as I tested) and (fortunately) every time I want to. BUT when I try to read it with my computer, in the same fixed internal drive I use for burning it, I'm able to do it only once. Every other time I insert the disc, I can't read it. After a while it tries to load it the disc seems to be empty. The same using another external usb bd burner/reader even on another computer. Both computers are Windows 7. BUT - external usb bd burner/reader - connected to my mac book pro - disc is readable again. I can't understand if the laser is going bad on my bd drive, if the disc gets modified somehow when I read it or what esle. Need help, suggestions are welcome

More layers and more TLC in NAND memory Thu, 10 Nov 2016 03:33:52 -0700 Vitaliy_Kiselev 16024@/talks/discussions

SK Hynix plans to launch the mass-production of 48-stack 3D NAND flash memory chips from the end of this month. This is the second time among global memory chip makers to do so behind Samsung Electronics.

In a situation where the flat micro-processing technology reached its limit at around 10 nanometers, 3D NAND was developed as an alternative to overcome the limit.

SK Hynix will increase its monthly 3D NAND output from 10,000 units in the third quarter of last year to 20,000-30,000 units by the end of this year, with the share of 3D NAND in its overall NAND output rising to around 15 percent.

The share of 3D NAND in NAND companies' overall production is forecast to rise to 57.8 percent in 2017 from 23.6 percent in 2016 and 6.7 percent in 2015.

SK Hynix is now developing the next-generation 72-stack 3D NAND and is expected to begin the mass-production from the latter half of next year.

Note that it is almost all TLC memory, not only it can have speed issues but rewrite cycles are lower and lower.

Today's commodity 2D MLC flash has raw wear-out in the 2,000 to 3,000 write cycle range.

Samsung TLC specs at 1000 cycles.

2D QLC (4 bit one) memory must drop to 500 cycles.

quick formatting vs. full formatting for video editing Sat, 17 Sep 2016 17:01:48 -0600 matt_gh2 15747@/talks/discussions Question for my fellow PVers. What are your thoughts on the benefits or lack thereof on doing a full format vs. a quick formatting. I bought a new 6tb external hard drive that is currently in NTFS. I'm going to reformat it Mac OS extended journaled. Does it make a difference if I do quick format vs. Full formatting? (It will be used for video editing and will have the video footage and audio files stored there.) Thanks, Matt

CFexpress - another type of fast cards Wed, 07 Sep 2016 10:28:56 -0600 Vitaliy_Kiselev 15674@/talks/discussions

The CompactFlash Association (CFA) announces the CFexpress Family of high-performance removable storage based on PCIE® and NVM Express®.

CFA has developed high-performance removable cards standards for the last 21 years with the popular CompactFlash®, CFast®, and XQD® formats. The CompactFlash Association was formed in 1995 as the initial digital film format and continues to serve professional imaging and industrial markets where high performance and high-quality recording media is essential for high-speed capture and high-speed transfer into the workflow.

CFexpress is the next evolution in an open standard format for a broader set of applications, such as professional imaging, personal computing, servers, IoT and industrial. CFexpress differs from prior CFA standards in that CFexpress is a specification spanning multiple form factors and performance levels to match various market requirements while maintaining the same electrical/physical interface and memory/storage protocol. The new CFexpress specification is under development within the CFA CFexpress Working Group.

CFA’s goals for the CFexpress family are:

  1. Unify the ecosystem around a removable storage specification that has longevity in the market
  2. Provide a platform that scales with performance increases in the PCIE® interface
  3. Leverages the technologies and skillsets of the larger volume compute markets
  4. Seamless compatibility with the capture ecosystem and workflow tools.

CFexpress leverages the PCIE® physical interface for higher performance based on the high-volume compute industry. PCIE® CFA’s objective is to specify multiple removable storage devices that spans from two lanes architecture all the way up to eight lanes. With the current PCIE® Gen 3 delivering maximum theoretical interface speeds of 1.0GB/sec per lane, CFexpress would enable theoretical sequential speed of up to 8GB/s.

CFexpress also utilizes the low latency NVM Express® memory/storage protocol across all of the form factors. This enables compatibility with a broader set of ecosystem components, such as controllers, OS, capture devices and workflow modules. In imaging, compute and industrial applications, the use of PCIE® /NVM Express® enables access to wide range of open standard platforms consisting of mature and proven drivers. In addition, the new CFexpress format also enable easy compatibility with the Thunderbolt® interface which is also based on PCIE®. Actual CFexpress products will vary in performance based on market requirements and protocol overheads.

Professional video data rate requirements are growing at an exponential rate exceeding the capabilities of existing open standard formats. 4K RAW video at 30fps requires 400-500MB/sec of sustained performance not including any overhead to guarantee performance over the entire recording media. 4K RAW video at 120fps requires 1,600-2,000MB/sec. 4K RAW video at 240fps requires 3,200-4,000MB/sec. Even in High-Quality I-Frame compression formats, the data rates quickly exceed 1.0GB/Sec at high frame rates.

  • PCIE® Gen 3 Interface Provides a max theoretical interface speed of 1.0GB/sec per lane of PCIE®. This speed enhancement enables a new generation of higher performance cards to meet requirements for professional video recording.
  • Family of Form Factors Provides multiple form factors to address multiple market segments with a unified physical interface and memory/storage protocol. 2 lane and 4 lane form factors will be the initial focus but anything from 1 lane to 8 lanes is possible. This provides a range of up to 8GB/Sec with PCIE® Gen3.
  • NVM Express® A storage interface designed from the ground up for NVM storage. The NVM Express protocol features fixed length commands, an efficient queuing model, and very low non-cacheable PCIe accesses per command, delivering reduced I/O overhead and performance improvements in comparison to legacy storage device interfaces. NVM Express® is gaining popularity across various flash-based storage solutions and has driver support on all leading OSs.

Mr. Tom Ando of Canon and CFA Co-Chairman of the board said; “As the Co-Chairman of the CompactFlash Association I am pleased and excited to introduce CFexpress as CFA’s continues the tradition of performance leadership. The higher performance provided by CFexpress formats will further increase the capabilities and value for photographers, videographers, cinematographers, industrial, and compute applications. I am very pleased and proud to see the CFA creating standards that address new market requirements.”

Host and card manufacturers will be able to leverage the compute industry’s investment in PCIE® and NVM Express®. 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 new VPG profiles at every increases performance levels. CFA’s goal for CFexpress is the development of a standard that can span many market segments and provide a stable and consistent format to fully leverage the industry’s R&D investments and less churn in the market of standardized and proprietary recording media formats.

Mr. Koichiro Kawamura of Nikon and CFA Co-Chairman of the board said; “As the Co-Chairman of the CompactFlash Association I am also pleased and excited to introduce CFexpress. The specification is a family of form factors that can serve many market segments with a unified physical interface and unified memory/storage protocol. We are excited with the vision that CFexpress will unify the imaging and industrial ecosystems around formats that are easily compatible with the computing markets. CFexpress represents a unique opportunity to unify the market around truly open standard formats.”

CFA invites host and media companies interested in supporting the new CFA specifications to also join CFA as members. Membership in the CompactFlash Association enables participation in CFA CFExpress Working Group and access to new specification before they are available for purchase by non-members.

GH4 Memory Cards. What works and what doesn’t? Tue, 29 Apr 2014 12:22:28 -0600 mpgxsvcd 10276@/talks/discussions I have a GH4 and the following 7 memory cards. Listed in order of their theoretical speed. Some of these cards have failed with the “Motion Recording was cancelled due to the writing speed of the memory card” error message in the GH4 and some have not. If they failed then it was always in the stills mode while recording 1080p @ 60 FPS 200 mb/sec ALL-I video.

These cards all failed at some point

  1. Eye-Fi 8 GB Class 6
  2. Eye-Fi 16 GB Class 10
  3. Transcend 32 GB Class 10
  4. SanDisk 8GB Extreme SDHC 30 MB/sec Class 10
  5. Transcend 64 GB SDXC UHS-I Class 3(Gold Plated Label)

These cards have never failed despite my best efforts to make them fail

  1. Transcend 32 GB SDHC UHS-I Class 1
  2. PNY 64 GB 90 MB/sec UHS-I Class 1

Please post your experiences with different memory cards and the GH4. Please only comment if you have the GH4 and have tried the memory card with it. No comments like “This memory card is better so it must work”. Just actual tests that you have performed yourself.

Back up solutions for video on the road Tue, 21 Jun 2016 19:43:27 -0600 mojo43 15262@/talks/discussions I am looking for suggestions on cheap and tiny backup solutions on the road that have high enough transfer speeds. Currently I bring my laptop and use usb 3 to transfer typically 2 64 cards a day.

Samsung UFS cards Thu, 07 Jul 2016 15:42:28 -0600 Vitaliy_Kiselev 15327@/talks/discussions image


  • 530 MB/s sequential read speeds
  • 170 MB/s sequential write speed
  • 40,000 IOPS random read rate
  • 35,000 IOPS random write rate


Samsung Electronics, the world leader in advanced memory technology, today unveiled the industry's first removable memory cards based on the JEDEC Universal Flash Storage (UFS) 1.0 Card Extension Standard*, for use in high-resolution mobile shooting devices such as DSLRs, 3D VR cameras, action cams and drones. Coming in a wide range of storage capacities including 256, 128, 64 and 32 gigabyte (GB), Samsung's UFS cards are expected to bring a significant performance boost to the external memory storage market, allowing much more satisfying multimedia experiences.

"Our new 256GB UFS card will provide an ideal user experience for digitally-minded consumers and lead the industry in establishing the most competitive memory card solution," said Jung-bae Lee, senior vice president, Memory Product Planning & Application Engineering, Samsung Electronics "By launching our new high-capacity, high-performance UFS card line-up, we are changing the growth paradigm of the memory card market to prioritize performance and user convenience above all."

Samsung's new 256GB UFS removable memory card ─ simply referred to as the UFS card will provide greatly improved user experiences, especially in high-resolution 3D gaming and high-resolution movie playback. It provides more than five times faster sequential read performance compared to that of a typical microSD card, reading sequentially at 530 megabytes per second (MB/s) which is similar to the sequential read speed of the most widely used SATA SSDs. With this UFS card, consumers have the ability to read a 5GB, Full-HD movie in approximately 10 seconds, compared to a typical UHS-1 microSD card, which would take over 50 seconds with 95MB/s of sequential reading speed. Also, at a random read rate of 40,000 IOPS, the 256GB card delivers more than 20 times higher random read performance compared to a typical microSD, which offers approximately 1,800 IOPS.

When it comes to writing, the new 256GB UFS card processes 35,000 random IOPS, which is 350 times higher than the 100 IOPs of a typical microSD card, and attains a 170MB/s sequential write speed, almost doubling the top-end microSD card speed. With these substantial performance improvements, the new 256GB UFS card significantly reduces multimedia data downloading time, photo thumbnail loading time and buffer clearing time in burst shooting mode, which, collectively, can be particularly beneficial to DSLR camera users. To shoot 24 large/extra fine JPEG photographs (1,120 megabyte (MB)-equivalent) continuously with a high-end DSLR camera, the 256GB UFS card takes less than seven seconds, compared to a UHS-1 microSD card which typically takes about 32 seconds, at 35MB/s.

To achieve the highest performance and most power-efficient data transport, the UFS card supports multiple commands with command queuing features and enables simultaneous reading and writing through the use of separately dedicated paths, doubling throughput.

As the leading memory storage provider, Samsung has been aggressive in preparing UFS solutions for the marketplace, while contributing to JEDEC standardization of the Universal Flash Storage 2.0 specification in September 2013 and the Universal Flash Storage (UFS) 1.0 Card Extension standard in March 2016. Following its introduction of the industry-first 128GB embedded UFS chip in January 2015, the company successfully launched a 256GB embedded UFS memory for high-end mobile devices in February of this year. As of earlier this month, Samsung also completed the Universal Flash Storage Association** (UFSA)'s certification program that evaluates electrical and functional specifications for compatibility of a UFS card, and Samsung's new UFS card products were approved as UFSA-certified UFS cards with the right to use the official UFS logo for the first time in the industry

And are the USB3 models backwards compatible to usb2 in case i need to plug them to my phone?

Nifty Thunder Rocket - Thunderbolt 2 SSD 1250MB/s read/write Mon, 19 Oct 2015 10:11:48 -0600 jmc 13961@/talks/discussions I just came across this from a company called Nifty. It's a Thunderbolt 2 SSD drive with similar read/write speeds to Lacie's LBD, but much smaller, fanless, bus powered and lower priced. It's aimed at 4K raw editing and ships in November but strangely there seems to be little or no info about it other than on the website:


I always wondered why there was a lack of Thunderbolt SSDs/enclosures on the market - I assumed it was to do with licensing to certain manufacturers, but that was just a hunch. I know there are a few around now from Lacie and the like, but all seem to be very expensive still and most aren't Thunderbolt 2 yet. This seems to be a step in the right direction, and I like the fact that it's PCIe rather than 2.5", but can anyone actually vouch for the company? And how likely it will live up to its read/write speed claims?
