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%!

Pre-recorded cassettes can sound good (really)

Unfortunately many people didn’t notice the improvement in the quality of pre-recorded cassettes, as they had stopped buying them by the time the developments covered in this (very wordy) video were implemented.

A fantastic insight into one of the many things consumer ignorance got the better of - Digalog.

Do you have a list of Cassettes recorded with Dolby S.

February 24, 2017 | Unregistered CommenterTerry

Unfortunately not - I don't think such a thing exists.

I learnt a hell of a lot from this video. Thanks for this. I am very fond of the cassette format but was, ignorant of the history and much of the process behind the manufacture pre-recorded cassettes. I always considered them to be pretty poor and Digalog passed me by! I will try to get hold of some of these recordings; this has really peaked my curiosity!

WEA's Digalog system used off-the-shelf Concept Design equipment for their digital bin. Concept Design was the first to introduce the digital bin, and this was BEFORE the cassette began its decline. WEA intended to use TDK ferric-cobalt tape for the promotion, and that's why cobalt is mentioned in the one press release. Experience, however, showed the tape had far too many problems running at high speed, so WEA went back to ferric tape as their main tape with chrome filling in when customers asked for it. (The Dolby S cassette at the end of the presentation is loaded with BASF LH-D ferric tape. We supplied 80-90% of WEA's production demand.)

The information about the benefits of cobalt and the problems with chrome is mostly nonsense. Of the names mentioned in Billboard and other publications posted in the video, only Joe Kempler and I knew anything about tape. Chrome is perfectly suitable for frequencies below 200 Hz, and it is far superior to any other formulation in terms of modulation and bias noise. Chrome tape was the only tape specified by A&M Records, Windham Hill, and American Grammaphone; and many major labels used chrome when artists demanded it. Cobalt was NEVER a threat to the use of chrome and offered no technical advantages. The reason metal tape was not used at high speed was that the bias required would make the slave heads too hot. Cost was also a factor.
