Yeah, but then a good recovery company should directly tap into memory or use their own temporary controller to access data. Link to comment Share on other sites More sharing options...
Ken Ross Posted May 25, 2017 Share Posted May 25, 2017 23 hours ago, tugela said: The write speeds on those particular cards varies depending on the card capacity. The 16GB version for example writes at 40MB/s, while the larger cards write at 75-80MB/s. Also, if you are using a UHS-I bus device you will only get half of that speed, so you would be better off using a high performance UHS-I card in that case. The 2000x cards run at much higher write speeds (~260 MB/s). All of those cards (with the exception maybe of the 1000x 16GB card) will be throttled by your device write speed, not the card write speed. I'm using the 64 GB Lexar UHS-II card with a stated speed of 150MB/s. In my GH5, the SanDisk Extreme, UHS-I, SDXC Class 10 card, with a stated speed of 90MB/s, is ready for the next 4K clip much quicker than my Lexar. So much for stated speeds. So it's not a question (at least in my case) of 'reliability', but shooting speed. Orangenz 1 Link to comment Share on other sites More sharing options...

Did you check your footage in the camera before taking the card out? Gh5 can't read or format the corrupted card. I was playing back our last shot everything was working great. I returned to shoot mode, turned off the camera and then took the card too soon out. Maybe when there is still this Lumix screen in monitor. Just a second too early.

Everyone can make a bad card, but no one can save you if you pull a card while it's being written to... I was not recording or playing back when ejected the card. I think it's because camera was still shutting down and making some last "writings/markings" to card. Also I have noticed when you flipp open the memory card door. GH5 sometimes writes/flashes the card slots like one second some times. Don't know is it possible to burn card on that moment. It's really wierd because sometimes it does it sometimes not.

So it's not a question (at least in my case) of 'reliability', but shooting speed. That Lexar has a write speed of 75 MB/s, and since (IIRC) the GH5 uses a UHS-I interface, only half of that is available. Which means the write speed will be ~37 MB/s. The Sandisk card probably writes at around 80 MB/s. If you want faster write speeds, use the 2000x cards. Those have UHS-II write speeds of ~260 MB/s for Lexar, and ~280 MB/s for Sandisk (or half if you use them in a UHS-I device). Both of them will be faster than the Sandisk card you are currently using. As a quick test on this laptop, I wrote to a 128GB 1000x UHS-II card I had handy to see what data throughput it would have. Reading off the hard drive and writing through a UHS-I interface to the card yielded sustained write speeds of ~30 MB/s, more or less what you would expect in that scenario. Any speed issues you see are a result of your equipment, not the card. 12 minutes ago, Teemu said: Gh5 can't read or format the corrupted card.

That is probably just the camera disconnecting from the card. The flashing light does not necessarily mean that data is being transferred, just that some card related operation has been carried out.

But for sure I know even if it is just disconnecting from the card or some other card related operation, it may burn your card if ejected at that time. Stupid me, human error. I will do human errors in future also and other people too. Only backups can save in situations like that. Link to comment Share on other sites More sharing options...

That would require physically accessing the silicon. Very few places would be capable of that, even the FBI would be challenged to do that. If you want to see the challenge, have a look at this video to see what is actually inside those cards: Link to comment Share on other sites More sharing options...

It's also much more forgiving of blemishes on faces like that of yours truly. The rendition of my shirt is also more accurate, more homogenous - in Standard and Natural, the colors don't blend together nicely as they do in Cinelike D. White balance may be a touch yellow, these are all straight out of the camera. Wrong topic? jonpais 1 Link to comment Share on other sites More sharing options...

JurijTurnsek Posted May 26, 2017 Share Posted May 26, 2017 How are we still discussing the card brand? Two fatal mistakes were made (removal midst writing and no backup card in the second slot) and any brand can fail. Anecdotally, a coworker of mine said he had to replace a SanDisk SD card multiple times under warranty and he is not a power-user at all. The topic should be renamed, the conclusion written in the first post and the thread should be locked. This is a witch hunt.
