Memory Cards Suitable For MP3 Player

Because of the size of MP3 player, the microSD card is the most ideal type of memory card used in MP3 player. Before buying the memory card, decide how much storage you need, the speed you want and whether the memory card is compatible with your MP3 player (you may refer to the user manual). If the MP3 player is backward compatible, it should able to read older format of memory card.

With the memory card, you can increase the storage size of the MP3 songs you install on the player.

It is my favorite brand whenever I want to get another memory card for my MP3 players or devices. You will never get wrong buying this brand.

      Happy shopping and enjoy the products you bought.

  • I never knew that MP3 players had a memory card. I never got to have one when they were a “thing”. I do think I could use these memory cards for other things – cameras & laptops. We are all visual humans & memory cards are great for us to capture our memories that will last forever. The only thing is once you take it out of the device, it can get lost so easily. Do you know where you could store the memory cards where they wouldn’t get lost?

  • I’m not really use a mp3 player but I really need to have external storage for my Samsung J6. And, I need the best and high quality microSD card since long ago, when I use cheap one, it’s broke too easy. All my data has been erased. So, now I’m using 32gb Samsung microSD. Maybe I’ll upgrade to 64gb pretty soon. So far, I’m quite satisfy with Samsung microSD. It’s compatible with my Samsung J6. Anyway, great article and to all reader here, GET THE ORIGINAL ONE!

    • I agree with you that getting the best and good quality microSD card to store your important data. It can be very frustrating when all your essential information disappeared due to faculty memory card.

      Samsung is also a good brand and it has many good products. I got my daughter a Samsung phone and my home uses Samsung washing machine. 

      You too can get the Samsung microSD card at Amazon with good price. I found one promotion of Samsung 128GB 100MB/s (U3) microSD EVO select memory card with adapter.

  • Hi there,

    I just read your article about Hot Electronics Products In Market. As i love electronics and gadgets i found your article like my kind of thing. You mention everything that is commonly used now a days like memory cards , mp3 players,  all about there specifications and different companies, there storage , everything is nicely explained.  Yo have also provided some links from where we can buy original stuff 


    • Most of the MP3 player’s makers would like to make their products competitive, and one of the strategies is reducing their internal memory storage size in the player. Thus, they offer external storage capability allowing you to add on extra memory card. This is the reason most MP3 players need memory card.

      SanDisk SD card is best suited to store your music on the memory card and you can purchase different capacity at Amazon or eBay online store. I personally consider SanDisk memory card as the best in the market currently.

      Class 10 memory card is better than class 4 and it will cost more normally when you do your purchase.

      Hope you enjoy your favorite musics on your MP3 player and bring along external memory card to store additional music when you come across new song you like.

  • Amazing job breaking explaining the memory card landscape.  I’m always at a loss when I need to pick one out.  It’s tough to get help in store to pick out the right one for your needs.

    Your grid on usage and purpose is invaluable.  I’ve book marked your page so I can get the right cards the next time I’m shopping for some.

    What’s the difference between a Memory stick and a flash drive?  I’ve heard that they are the same except that Memory sticks only work with Sony devices….is that true?

    Thanks again for a great tutorial!

  • I remember when I bought my very first MP3 Player. It only held 20 to 30 songs which meant I had to keep deleting songs if I wanted to add new ones. It was so frustrating lol.

    But today, MP3s have come so far and I can’t believe the amount of storage space memory cards have!

    I do like the fact that memory cards seem reasonably priced too, which means you don’t have to spend an arm and a leg for some decent music storage space.

    However, even after all these years, I’m still not up to date with the lastest and greatest technology. So in addition to music and video use, are memory cards great for some smartphones and digital cameras when it comes to taking photos too or are they not needed since Apps exist for storing photos?

    Cheers, Neil

    • Hi Neil,

      Thanks for the comment.

      Technology continue to evolve therefore the newer MP3 players have so much features and performance than its predecessor. You can store more songs on all the music players nowadays.

      For smartphone and digital camera, the application is likely to be video in nature. Therefore, you ought to choose the highest speed and greater capacity of the SD card when you make purchase. 

      Although cloud-based storage is becoming common in these days, having additional backup onto a portable SD card serve you well and allow you to transfer easily without any internet connection.


  • Thank you for your solid informations. I thought SD cards are outdated and technology is moving toward built-in memories. I didn’t know that the new generation of SD cards (SDXC) has a capacity of up to 2 TB. The rapid technology advancement excites me.

    However, for my mp3 player the old 32GB SD card is still enough. Do you know which devices are now supporting high capacity SD cards?

    • Hi Albert,

      Use of memory chips in any device will cause the manufacturers money, therefore most of them tends to cap their built-in memory at certain storage size in order to price their product competitively.

      With 3D application rising year after year, the adoption of SDXC card is likely to move into main stream the coming years. We will see more new applications on board and our life style may change progressively.

      SDXC uses different file system named as exFAT and it is based on SDA 3.0 specifications. To ensure that the card and its host device work well, you need to look for the SDXC logo on the card and host device.

      You may refer more information at the website of SD Association.

  • Hi there,

    I have to say that this article contains really helpful information! I never understood (until now) why SD cards with the same amount of storage have completely different prices. Well, now (thanks to you) I know.. it’s not only the memory that counts but the transfer speed as well. I can say for sure that the next time I need an SD card I will definitely know what and from where should I buy.

    One big THANK YOU!


    • Hi Nick,

      I am glad that my article provide guidance to you in choosing which SD card to use.

      If the transfer speed is too slow, it may take you more times in retrieving the data stored on the card. When the data recorded is video, the delayed is even more obvious. 

      I used to carry many USB flash drives with different applications on each device, but not anymore. Nowadays, I store all the data on one single SD card and it simplify my job so much easy and efficient.

      Don’t forget to visit my recommendation and check them out at Amazon and ebay marketplaces. Both offer very attractive pricing and various memory sizes for your consideration.

  • Thank you! I often use SD cards, and there is a lot of difference in quality, memory, and price, often depending in which shop you are buying too. The Amazon prices look good. Great video which break things down into understandable pieces, good to know that for a music application on an MP3 player a class 2 is sufficient. It is very useful to buy a card reader at the same time, you can easily connect such a device to your laptop and read all your memory cards. Easy when you’ve mixed a few.

    Thank you for the Titanic “Song” on your About Us:) I have enjoyed it!


    • Hi Loes,

      Glad that you love the Titanic song. I love it too as the movie was very romantic and full of passion for young couple when they are in love. It will be great to put that song onto the MP3 Player and carry along.

      You are right to say there are many different types of memory cards on the market. Depending on your application, we do not need to buy the most expensive and sophisticated type, just the right one is good enough. Easy for your pocket and also meet your need.

      Amazon always has good promotion and many deals can be found on its marketplace or online store. You can also purchase the card reader on Amazon. There are various options for you to select. 

      Here is one of them, Anker 8-in-1 USB 3.0 Portable Card reader

  • I’ve been on the lookout for a way to boost my Mp3 player’s memory for quite some time now, I use it for running every morning and I’m a bit sick of the albums on there! 

    To be honest with you, I’m only looking for a few Gb more really – do you think the quality of the 16GB microSD card Class 4 options is good enough? For just over $6 it’s perfect for me if it will last. 

    • Hi Chris, 

      microSD card with Class 4 + 16GB storage capacity will allow you to store your favorite music on the memory card. This is sufficient for application like this type and you have more space to get your music on it.

      As the price of memory chip drop further, you will be able to get more byte on the card. More memory give you more option to store your favorite album. 

      Thank you for giving your comment on my site.

  • I just purchased a new mp3 player which needs a memory card but the seller on ebay (who I contacted) does not have an instruction manual for the device which only states on the front that it is a digital mp4 player/zy. As you mentioned:
    Before buying the memory card, decide how much storage you need, the speed you want and whether the memory card is compatible with your MP3 player (you may refer to the user manual). If the MP3 player is backward compatible, it should able to read older format of memory card.

    I don’t know which memory card to buy and I don’t know whether its backward compatible? (I don’t know what backward compatible means)

    But anyway, I was thinking of buying a 64 gb TF card Class 10 and I have not seen any class 2 cards as of yet. I only intend to record music at the least off the built in FM radio or from a cd in my laptop.

    Hope you can answer my quetions.


    • Hi Mark,

      Glad to receive your query.

      Backward compatible means the MP3 player can read older format of memory card. However, as technology changes super fast nowaday, the newer MP3 player may not cater to all the old format of memeory card. Therefore, it is prudent to transfer your data often from the old device to the newer one, once a new technology is being introduced in the market.

      It is pity that older generation will have a hard times to keep up with the new technology and need to re-learn constantly.

      Class 2 is consider rather slow speed with modern time therefore you may not see it in the market anymore.

      Your decision to get a 64GB memory card with class 10 should be sufficient to record your music. Big brands like SanDisk, Toshiba, Kingston are good to consider.
      Hope you enjoy your music often while out from home with your lovely portable device onhand.

      Best regards.

  • Thanks a lot for this helpful article. I learned a lot about different memory cards. As I travel often, I like to have my music recorded on an MP3 player. So I need a good memory card. I’ll look it up on Amazon because I’m one of those people who likes to shop online.

  • Many thanks to you for sharing such an excellent article with us .When I used a phone before, my phone had very low phone memory then I had to use the memory card especially for mp3 player.And since then I started using the memory card on my phone and now I have purchased a new phone where I do not need a memory card, I still use the memory card.I use my memory card at Toshiba Company.And it’s a very good company and I’ve been using it for a long time and I haven’t had any issues and my device is still up and running.

    • Hi Shariful Islam,

      Toshiba used to produce many memory products in Japan and the last I know their flash memory is very competitive in the market. But with advancement and competition, Toshiba is out of the game now. 

      I would suggest you consider SanDisk or Samsung when you want to get your memory card. Both of them have long term planning for their product line up and you will be getting support long term for your memory card.

  • Thanks for sharing a very important article with us.

      I have been involved in memory products for many years, since 1997. During that time, memory chips are expensive and most memory cards are used in corporate. Consumers like us cannot afford to purchase it, not even thinking about getting online as there is no internet connection.

      The world has changed so much since then. Memory cards come with different platform and various format. We now have so many options to choose. I wish this article help you in understanding the memory card product features and allows you to choose the right one for your usage.

  • Hi there, thank you for writing this informative and useful article. From your article, I can understand the function, the types, the pricing and the different brands of memory cards that best suits for the MP3 player. The microSD card is the most ideal type of memory card due to the size of the MP3 player. I can download the songs depends on the storage size I’ve got with the memory card. It is great that the memory card can be removed and transferred the file to the other devices so that I can listen to the music not only on MP3 player. Thanks for your post! 

    • Hi Miki,

      Glad that you are using microSD card to store your favorite songs on it and bring along your MP3 player to wherever you like. Music give us good feeling, especially when we are in bad mood and nice songs can really bring us up.

      SanDisk and Samsung have very good selection of microSD cards in their product family. Do check it up at Amazon store and fill your heart with beautiful songs you love. 

  • Many thanks to you for sharing such a beautiful article with us and I get the opportunity to discuss a wonderful topic through your article. The modern-day information technology has become very modern and we can no longer afford the technology with which we could use it five years ago. Three years ago, I could save a lot of songs with a 4GB memory card. But now it is not possible. The size of the memory card in the current market is 16GB 32GB 38GB etc. The current song and video memory size is all the better and much better than before. So we should use the advanced memory card and I am currently using the Sandisk memory card .I think your article very useful articles and I would like to share article on my social media.

    • Hi Shanta Rahman,

      You are right. 4GB memory card is not available in the market as technology make advancement and company improve their product features. 

      Although we have cloud to store our songs but when there is no internent connection we will not be able to access those songs. Memory card allow you to access your favorite songs anytime and anywhere, without any concern of the internet availability. 

      SanDisk has many product categories of memory for you to select, depending on your needs. Feel free to visit their website often and subscrbite to their product news. You will get notice when there is new product available.

I think from your review, SD card with SDXC is the best one that I have to purchase and ho it will help me to store my files. Can I order multiple orders at one time?

    • Hi Shimba,

      Yes, you can order as many cards you wish. For me, I like to store different products in different memory cards. This allows me to categorize them with different needs and also easy for me to identify when you need them.

      The price of memory cards have came down quite a lot and most of us can afford to buy few cards at one go. 

      Thank you for dropping by at my blog and I wish you get your favorite memory cards in sooner time.

    Previously, I would only consider the capacity and the price, but thanks for posting this very informative article, I’ll have this as my guide when I buy my next memory card. From the knowledge I gained from this post, I can be able to assist other people.

    God bless you more,
