Old videos are still relevant.

Woooo ! Congratulations ! This video should be the golden standard for all comparisons. 5 Years later it is still very up-to-date. I understood a lot of things with this video, which is the goal of such educationnal video, right ?

Oh why can't all explanations of technical frustrations be explained as clearly, concisely and calmly as this?

this guy is the nemesis of those blabber jabbering speed merchants that pervade KZfaq.

After watching a bunch of videos about SD cards, I'd say this is the best one yet despite the video being 6 years old already

Finally, an informational video on KZfaq that's explained and presented extremely well, without annoying and distracting background music or by a person who can't speak English well enough to understand every word. Ty

At less than 5 months from the introduction of the Raspberry Pi and all the others, your comment at 5:19 is prophetic in nature. Now Class 10 or U1 are the standards we use for the SBC's. Your archive is a wealth of information!

“And start at 36 gigabytes and rise to a theoretical 2 terabytes” The World: *laughs in petabyte*

This guy is very good indeed.Very informative. I also like the old school style presentation. Great stuff.

Best channel on computers

Mr Barnatt you are the best here in youtube explaining computers and peripherals! I'm very very glad to watch your videos. I'ts too much knowledge for all the world! Even me Who is a brazilian guy and learned english alone, your british enlglish is very easy to understand. Congratulations Mr Barnatt!!!

June 1, 2016 - Thank you very much. The part where you froze, dropped and thawed the SD card was both funny and informative. The idea of storing data other than jpgs on an SD card I have never considered. I'll have to try that very soon. My fav is Sandisk micro SD cards class 10 32G Bytes used in a normal size SD card holder. Thanks again, Christopher B..

Great video, pleasure to watch. Narrated with clear and calm voice and without distracting clips this video is very informative. Also, the tests performed on the SD card are straight forward and easy to copy. This video reminds me how the ICT technology was introduced in 80s :-) Back then there was so much hope for bright future.. :-/ Great work, thank you.

Thank you very much for taking the time to create this video. I appreciate it - very informative!

Reminiscent of the old 70's Open University presentations. That's a compliment btw.

i watched this video at 2016 and i figured out again that technology improved very fast in 5 years

Welcome from the future, we now have a 1TB microSD (but it's very expensive).

I wish there was a 100 TB micro sd card

This reminds me of technology presentations in the 80's :P Not bad though and the bit about the waterproof was interesting.

Excellent summary of SD card specs. This stuff blows my mind. I have an old 4K core memory modules as a souvenir of my mainframe computer days. Eight data bits plus one parity bit for each of 4096 locations! Takes as much physical space as several hundred of these SD cards.

Excellent video, thank's Christopher.

I loved you video! Not only you taught me what what the product was, but you told me the efficiency of each one, and the value uses of them all at the same time being compact facts that are easy to remember and weren't explained with long facts that I wasn't seeking. Simple, straight forward and very helpful answers, in other words. :)

Yesss , you can learn a lot from this guy, I wished he was my teacher we in school

Thank you for all your videos, tests and explanations...highly informative.

Your old intro was GOOOOD🔥🔥

An excellent video on SD Cards -- answered all my questions.

Chris, since you changed the music and graphics you seem a little , well, subdued. You don't seem to be as excited as you were or having as much fun. Your videos are still excellent. There are a number of things I enjoyed about your older presentations. Your excitement when unwrapping a new piece of hardware or finding out an unexpected feature on a simpler board such as one of those $10 computers. The music that hearkened back to early computers. The exciting WHOOOOSH when the next section began. Much of it reminded me of how exciting things were when I had my first Texas Instruments TI-4A computer, when simply having music or hearing speech was an exciting new thing. I just writing this to let you know that you are appreciated and enjoyed, that although I may not tune into every video (the subject affects that), the ones I do watch are very satisfying indeed. (I loved seeing your Wallace & Gromit cup and your snack during a time when you had to wait for something in another video.) I hope everything is all right for you and no great tragedy has befallen you, either related to the channel or personally. I'll be looking for your next video and "I hope to see you again VERY soon".

A honest expert on SD Cards

There are not a lot of devices using SDXC yet. I know the Canon XA10 camcorder that I shot this video on can use them, as can some other camcorders and high-end DSLR cameras. But that's about it at present. And there will be very little reason for many devices ever to require the speed of SDXC.

Thank you for telling me about this sd card thing.....I found it is very helpful to watching this kind of explanation or tutorials that is very easy to understand it's content....Hope that this kind of videos is continuously make by you so that it will help more people understand about computers and other stuff that included in computing

Simply put, well articulated, excellent experiment.

Thank you! Great as always! Please keep the videos coming more often!

you surprise me again with another great explanation and you made me realize that they are very important to store data and back ups of critical files due to its small size and robust

Thank you so very much! My Father was the one who always explained the computer and hi-tech world to me. I miss him a lot , but I'm sure he was the one who led my to your vids! Thanks again !

Your videos are so much clearer than most.

Highly useful and infomative, technically and presentationally superb - yet again you are a pro!

Thank you for this video and explaining all about SD cards. It has been hard for me to find out this information and this helped me much.

Helpful is the right word, thank you Barnatt, you took away my doubts, congratulations!!!!!!

This video is so well-constructed.

I benefited from this video, and we are in the year 2020 at the time of the Corona pandemic, and you have made this video for nearly 9 years. And the best thing that I benefited from this video is that the sd card cards are hot and cold water resistant even to the freezer and shock resistant and after all these dangerous severe experiences of these memories remain intact and without any significant damage as can be easily hidden in the money wallet and pasted under the table And hide it anywhere we wanted ... it's really cool. You are also wonderful, Mr. Christopher Barnatt

@elpilito1990 Thanks for your kind feedback. Having bought Sandisk Class 4 cards you may be lucky, as Sandisk cards tend to perform faster than their class rating (which is a guaranteed speed minimum when new). But as you imply, trying to shoot full HD on a class 4 card is hopeful. Fingers crossed! :-)

Thank you for this video. You did an amazing job!! Loved this!

Yes, if you want the very best SD card for HD video at present, get UHS-1.

Informative. Simple explanation. Nice demonstration. Excellent video. Thank you for educating us for free. Great job. Two thumbs up.

I love these videos because it's a man who looks like he's from the ninties explaining current-gen technology in a video style resembling that of the early 2000s

They are quite robust. Was not aware of that. Great video

Great video. Very informative!

Thank you for clearly explaining what the differences are between the types of SD card. :-)

Welcome Back Professor Barnatt , I hope your feeling better. Great video as always.

I don't know about other peoples replies but I am new to all this and I have been watching a lot of your vids and you been very helpful to me.

Thank you for a great video! Keep on the good work!

You make a very good point -- SD cards (and other flash memory cards -- though SD is the most popular) do exactly the same job as USB keys. Currently more desktop and laptop OC have USB ports than SD card slots, hence the need for USB keys if you want to carry data between unknown PCs of this type. But increasingly smartphones and tablets are more likely to have a (micro) SD slot and no full-size USB port -- so SD is becoming very widely used.

The lack of free space could well be the problem if the phone is trying to write cache or other files to the card.

Amazing explanation!

This video caused me to flashback to the seventies when I saw the hair.

@ExplainingComputers thank you for a quite informative video on the differences in different SD cards and what their differences actually are. I'm expecting you'll make more videos as this one was done 4 years ago.

Your videos are very informative. Thankyou!

I do not say that 2TB cards are available. Rather, I cite the specification of SDXC cards as ranging from "32GB to a **theoretical** 2TB".

Thanks, Christopher Barnatt. I found your video on SD cards very informative. I have subscribed to your channel. Thanks again! :-)

I once put a 64GB SDXC Micro SD Card into a SDHC Adapter and SDHC Card reader and it worked absolutely fine

Is it a Canon XA10 -- the smallest camera in Canon's pro range -- and shoots 1080p 24Mb AVCHD files to one or two SD cards. Most of the footage in this video is shot with this camera (aside from the shots of the camera itself!).

Original, concreto y directo. No se puede pedir más. Gracias por subirlo.

Indeed -- and 128GB cards are now on the market -- so 2TB cards are only a few years away now. The max capacity only had to double four times now, and a doubling of maximum capacity seldom takes more than 6 months. :)

Your Technology Explanations Are Always The Best! Very Clear, And Easy To Understand For Anyone. I Love Your Channel!! Now, I Haven't Seen All Of Your Videos. So I Have To Ask. Do You Explain Technology Of All Types? For Example: TV'S, Gaming Consoles, Phones, Cameras, ETC. Or Do You Only Stick To Computers And Their Accessories?

This is an excellent video. Thank you for sharing this online. :-)

Amazing job ! The video was just so good 👍

Great video very clear and to the point.

Great Vid. Very useful and informative, thanks.

Yes -- almost boiling water! Some initial experiments proved that it would have taken ages to melt the ice without it.

watching in december 2020 . best videos for basic info

Another masterpiece from Chris !

very professional video, brilliant explanation thanks!

Came here after you said in the 10yr anniversary video what the recent surgery had done to your throat. Although by comparison to your normal pitch/tone/energy etc you do sound a bit more subdued, unsurprisingly, it was still a great and informative video to watch. One thing about 64gb micro SDs I've found recently is that Windows won't format them FAT32, TP programme required.

Thanks a lot in this video I learned many things

No. Providing that the card works, the image quality will be the same regardless of the card specification.

Great explanation!

Excellent tutorial !

Great video. Keep up the good work.

To be certain of recording HD video with no problems I would opt for a Class 10 SDHC card. A class six card may well be OK, but could cause problems with recording the 1080p 30fps video that this camera can produce. I see that Hero state that you need a class 4 or above SHDC card for this camera (though that may only work for its SD modes I guess). But the cards Hero sell for the camera via their website are Class 10 Sandisk SDHC. So if it were me I'd buy class 10 if you want to use HD.

Thank you. This was very good. I am a level below novice with any of the recording devices.

Excellent video. Thank u for sharing.

Even in 2020, this is still revenant somewhat. The stress test experiment is oddly satisfying to watch, even tho it’s simple.

Great vid. Helped a lot. Thanks!

your video are my goodnight story before i go to sleep

Great Job. Many Thanks !

Up to 2 Terabytes is a very large amount of data for most users. My computer hard drive is just 1 TB. I think it is really amazing how technology has made this possible. I have an 8GB standard SD card for my Kodak Digital camera and have never got past 3 GB of images stored on it, and there were literally several thousand images on it.

Duuude THANK YOU!!! Great video!

Thanks for the tips!

Thanks for this. Micro and mini SD cards have exactly the same speed classes (though are harder to find in the higher classes), so, class-for-class, their IO speed is identical.

I don't know. But it is quite possible that an instrument like that may only accept older or lower-spec cards, as manufacturers of non-PC electronics tend to update their hardware far less frequently.

Fantastic video:)

another great video

Nice one, cheers for the vid!

Thank GOODNESS you explained it so simply - many many thanks

excellent sir!

Well presented, Thank you so much

I'd be interested to see how the different brands stand up to repeated writes to the same locations.

Thank you forbthis video. Just what I was looking for. Regards.

Many thanks! :)

Thanks for a great video. I am a new subscriber as of now.
