What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.


RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)


U3 CARD (For 4K cameras)




The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for's some.


VERY IMPORTANT. These links take you to the product, however Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market Place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

Hi Mat, facinating and brilliantly informative, I don't know how you do it and find these gems and make a super video telling us all about it - sheer magic.

Thanks for listening

An interesting appearance of a wire recorder in film is in the film "Dick Tracy" (A cinematic masterpiece on it's own).

Thanks for the comprehensive rundown of the wire recorder, a fascinating device.

Thank you! Although I'm not an audiophile I was enthralled and fascinated. Having those old recordings is what made this particularly interesting for me. I love that someone was using this to make their own "mix tape" - one can only imagine how proud they were to show their friends that they could put all their favorite songs on one recording - no more changing the records just to hear your favorites.

By the way, this machine looked particularly beautiful in 4K - thanks.

I've heard something about this machine, but never seen one in action. Interesting video. I don't know how do you manage to acquire these beautiful machines. I can imagine it's as difficult to buy them as to explain to your wife how important is adding another machine to your home (LOL). Keep on with your interesting and well performed videos.

The German Magnetophone and BASF tape were not secrets. AEG introduced both at the German Radio Exhibition in September of 1935. Americans did not pay any attention. (They did not pay any attention to Oberlin Smith, either. He's the American who patented magnetic recording in 1887 before Valdemar Poulsen came up with the idea.)

When you showed the cigarette ad, I was convinced you were going to discuss Fritz Pleumer. He worked for a cigarette company in Germany that decorated the tip if their cigarettes with a "gold ring" consisting of fine bronze powder glued to the paper. The bronze kept coming off onto smokers' lips until Fritz figured out how to get them to stick. In 1928 he figured he could attach fine iron powder to paper to make a magnetic recording medium. It did not work well, but his idea went to BASF engineers who tried iron carbonyl mixed into a cellulose acetate film as a better alternative in 1932. By 1935 and the exhibition, BASF had made great progress in developing a recording tape not much different from we all know.

That's truly a very nice video...... Actually I have this instrument..... My great grand father purchased this long time ago but we do not know how to use it..... It would be a pleasure if there is such a video made which tells how we can use this audio machine!!
