What type of micro SD card for large amount of write cycles? Thread starter tfe Start date Nov 1, The Dash Cam I use will record all the time when driving and probably when standing still too. That results in a massive load of videos and therefore a massive writing onto the micro SD card.

Well, Never! Why would you need to format your card anyway? For those that are interested, wear levelling works a bit different than what most users think of it. In fact, wear is not spread out across all blocks evenly. Rather, when a block can no longer be written to, the controller inside the flash card detects this and allocates a spare block to replace that block, and internally remaps that block. This generally can not be detected by the hardware that is using the flash card the SD or CF controller and is totally transparent.

So in effect, a block is mapped out and replaced when one is needed. There may be specific filesystems out there that seek to minimize erases by organizing writes sequentially and what not, but that is irrelevant to the inner workings of the card. But the little box or case around that circuit and terminal posts might not last as long due to wear and tear. But some makers, like SanDisk and Lexar make cards that are supposedly tested to hold up better in adverse environmental conditions.

Those are the ones the pros should use! If I had the possibility to vizit the Gran Canyon I woud use the most reliable equi ment. An earthquake can close it…. Now , the question was not answered. We have a photo of my father. Circa a. D Memory Cards are integrated cir cuits. So , I am afraid that the answer is NO!. The answer is similar. I still have a 1 Gb microdrive from about 10 years ago. My camera does have four or more times as many pixels now as I had then so that makes it seem even slower.

The cards are about 5 yrs old and i use them everyday. As a pro I find having a dslr with two card slots to record to both is recommended for inportamnt events such as a wedding. Which leads me to my next point. This bag is extremely heavy. All those little leather. Thanks for the post — I was looking this up on google after my card suddenly started giving me corruption errors when transferring files to my PC.

Cheers, just listening to the PhotobizX podcast where one of the photographers interviewed was saying that he only trusts his cards for one year and replaces them after that. So if I am just using the Micro SD Card as storage drop a movie or file onto the card as its permanent location it should last for a very long time as I am not writing and erasing the files?

I basically am converting some of my DVDs into a video file for my tablet and then loading them onto a Micro SD Card and leaving them there. When the card is filled I wont be erasing anything just reading from the card. I recently ran a cellphone through the washing machine it was so dirty , and the 2 GB microSD card works just fine in my new phone I eventually got the washed phone working too, but it was a good excuse to upgrade.

Individual flash memory cells have a limited lifespan. That's the bad news. Write cycles are important, but MTBF mean time between failures is often 1M-2M hours or more, factoring in advances such as wear leveling, bad-block marking and management, etc. The BBC article Digital memories survive extremes covers an interesting study by Digital Camera Shopper on the durability of memory cards.

The memory cards in most cameras are virtually indestructible, found Digital Camera Shopper magazine. Five memory card formats survived being boiled, trampled, washed and dunked in coffee or cola. In , there was an incident covered happily in a SanDisk press release at the time where a photographer's compact flash card survived a bridge explosion where the camera gear was set up so close to the blast that it was destroyed, but the CompactFlash card survived.

Other incidents like plane crashes are hyped by SanDisk so much that, admittedly, I get nervous using other brands. That said, it's not always easy to get data from a damaged card. An atmospheric research balloon crashed in the Pacific Ocean and was recovered.

One SD card was read easily but another required intervention from SanDisk, but it was eventually read. If you suspect a card may be getting flakey, or if you run into trouble reading a card, immediately create a backup of everything on the card.

There are low-level recovery tools like TestDisk and PhotoRec that come in handy for this. I've used several brands of SD cards in raspberry pi computers, and they usually start seeing memory corruption after a continuous uptime of anywhere between 1 to 3 months, larger SD cards seem to last longer, smaller SD cards wear out in just a couple of weeks.

It is a journalled filesystem previous teams' decision and I have seen a handful of failures in a population of say devices, with some brands having more failures than others. Some are complete catastrophic failures, I can't read nor re-partition and re-format the card and some are simply filesystem corruption and a re-partition and re-write has them working again. We don't trust those to be sent into the field however.

They have only been in the field for a maximum of 3 years. Thank goodness the real information has already been sent to a database and stored. You can theoretically damage them with a severe enough impact. Don't short the pins, or use them in space. Don't use them for long term archival purposes - in years several of the compounds will have started degrading and no-one will know how to read them any more.
