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%!

The Picocassette - the smallest (analog) tape cassette ever made

My quest to demonstrate unusual tape based audio formats might have reached its conclusion with the Picocassette. This is the smallest analogue tape format ever released. Created by Dictaphone for their sophisticated handheld voice recorder, the high price and well established competition, meant the Picocassette was a commercial failure. Introduced to the market in 1985, the same year that Back to the Future debuted at the cinema, I've used my own time machine to get hold of a BNIB example of this 30 year old technological wonder. 

If you are lucky, you may still be able to get hold of one of these on ebay.

Dear Matt, Thank you for your wonderful reviews.
I don’t know how to communicate with you directly other than through the comments section.
I spent most of my life in the Hi Fi trade, either as a salesperson or a manager and buyer. ~I also did some consultancy work and the company I worked for also produced the Legendary JR 149 speakers, designed by Jim Rodgers.
I got out of the trade because I got fed up with people discussing the merits of which way round they should connect their cables and if they should buy an overpriced bit of kit to lift the cables off the ground because it made them sound better. They seemed to loose site of the enjoyment of listening to the music rather than “Sound” of the equipment.
Things have not changed much as I see people on you tube discussing the merits of FLAC players over and iPhone and one person concluding that an iPhone was superior to a sony Flac player and that 16 bit flies were sufficient over 24 bit files ????
Have you ever thought of doing a review of a Flac player versers an iPhone ?
If not I would ask you to consider it please.
I might be 60 with diminished hearing so I would like to know if it’s worth me while investing in a Flac player.
I had been considering the Sony but one person said they were rubbish compared to an iPhone.
I had also see someone making comments about the new Astell & Kern AK380 and how good it is.
I appreciate it is a very expensive Flac Player but I trust your reviews.
It would be nice to hear your comments on should we or shouldn’t we ?
Regards Jeremy Travis.

Sound quality isn't too important me. I do have the Sony HAP-S1 at home. Whilst the Sony can and does play 'HiRes' files, I really just bought it for the way it operates rather than how it sounds. I'd imagine my retro amp will be having a negative effect on its sound quality, anyway. I'm just as happy playing an 8-track tape as I am the latest hires files. I just enjoy the music. I've got a Pono player too, but the biggest improvement I've experienced in portable audio in recent years was when I bought my Bose quietcomfort 25 noise cancelling headphones. Playing the tapes I recorded off FM in the 90s are now as enjoyable on my train commute as I would the latest hidef files.

In the days years ago when I was in a senior administrative position, I had one of the very first Pico cassettes. I bought one of these when Dictaphone first introduced the picocassette. I had the portable unit and my administrate assistant had the desktop transcribing unit. I think the desk unit might had a foot control as well to free up the transcribers hands. This unit is sturdy as a tank, I used it for about a dozen years and kept it as my constant companion, on my desk, in my pocket, and in my briefcase. I dictated everything and only used a pen to sign my name. It never failed and always worked like a charm. Also a few years ago I sent the whole kit to electronics recycling. If was fun to see the article. It brought back many memories. Thanks.

When I was in the consumer electronics trade the smallest cassette players were either Olympus or Sony.
I remember when reporters from the BBC used to walk about with Sony TC55 mono cassette recorders.
Eventually Phillips produced smaller cassettes.
Sony produced some smaller and thiner Micro Cassette recorders which I was asked to hide in cigarette boxes or attache case for people that wanted to secret recordings. Some were detectives and some were from the Russian trade delegation.
Who would thing we would end up with flash memory recorders at half the price and much higher recording quality.
